Chinese JV to build stainless steel plant complex in Indonesia

SEATTLE (Scrap Monster): Two Chinese firms have committed to make total investments of US$ 1.63 billion in Indonesia. The investments will be made towards construction of a stainless steel plant and a power plant in Morowali Industrial Area, Central Sulawesi as part of joint venture projects to support development of industrial areas outside Java. The projects are expected to provide big boost to infrastructure development in eastern Indonesia, by reducing the need for imports of steel. In 2016, the country had imported more than 50% of its steel consumption.

The memorandums of understanding (MoUs) to this effect were signed on the sidelines of the China-Indonesia Cooperation Forum: Belt and Road Initiative and Global Maritime Fulcrum held in Beijing on Friday. The announcement of fresh investments in Indonesia follows the bilateral meeting between Indonesian President Joko Widodo and China’s Xi Jinping at the Belt and Road Forum for International Cooperation held last month in Beijing.

The Indonesian Industry Ministry’s director general for metals, machinery, transportation and electronic equipment, I Gusti Putu Suryawirawan stated that Chinese Delong Holdings Limited plans to invest around US $ 980 million to build a stainless steel factory at Morowali. The company will form a joint venture named PT Dexin Steel Indonesia to build the plant with a production capacity of 3.5 million tons. Delong’s subsidiary, Delong Steel Singapore Projects Pte Ltd will own 45% of shares of the joint venture, while 43% will be owned by Shanghai Decent. The remaining 12% will be owned by PT Indonesia Morowali Industrial Park. The plant will manufacture steel bars, wire and slab.

Suryawirawan stated that the 2,000 hectare industrial park is an ideal location for the proposed stainless steel plant, mainly due to the presence of nickel smelter within the park, which can meet the raw material supply requirement of the plant. Morowali would turn out to be the second steel factory complex in Indonesia after Cilegon in Banten, Suryawirawan added. A feasibility study has already been commissioned by WISDRI Engineering and Research in connection with the project, he noted.

In addition, another memorandum of understanding (MoU) was signed among Tsingshan Group and Bintang Delapan Group and PT Indonesia Morowali Industrial Park towards construction of two power plants in Morowali Industrial Area, Central Sulawesi. The plants, with a combined capacity of 700 MW, will be built at a total investment of $650 million.

Meantime, Minister of Industry Airlangga Hartarto appreciated the business to business cooperation between China and Indonesia. He noted that the recent MoUs will help to accelerate development and prosperity in Indonesia.

Sandblasting with anticorrosive undercoat

No, the new white colour is not a new marketing strategy, we are not changing the colour of TAURUS shears and balers. The distinctive white colouring is the result of the special anti-corrosive treatment performed on each and every component of all new Taurus shears and balers. This special treatment prevents rust and corrosion from damaging the metal components of the shears, balers and shredders while also ensuring that the top coat of paint is more vivid and stays durable for longer. TAURUS shears and balers are in constant contact with abrasive scrap, and if placed outdoors are at the mercy of the elements. Thankfully, by applying this anti-corrosive, two step primer, rust, peeling or fading of the paint is minimized.

The anti-corrosive treatment described involves more than just applying an undercoat; several stages of the treatment are required. First, all components must be sandblasted:

Sandblasting is a mechanical cleaning process which involves spraying the surface of the metal with an abrasive grit at very high pressure. This process removes all foreign substances such as calamine and  metal oxides from surface of the metal and also gives it a rough finish for better adhesion of the final UV protective topcoat.

 

HOW do we do it?

Sandblasting such massively heavy objects which can weigh 30 tons or more provides special challenges in itself. The job is undertaken by qualified personnel in a separate department with the aid of suitable lifting equipment. Sandblasting is undertaken manually so that we can be sure that all areas of each component is completely free of contaminants before being sprayed with the anticorrosive undercoat.

 

After sandblasting, the structures are hand painted with a layer of twin component undercoat which provide much better adhesion properties for the final topcoat while also protecting against all manor of atmospheric and chemical agents, abrasion and damage from impact.

Shear components which undergo a further manufacturing process at our CNC machining center are sand blasted and painted separately before final assembly and application of the topcoat.

The work intensive process of sandblasting and applying an undercoat is not often followed by other manufacturers but never the less deemed necessary to ensure the high quality, long lasting finish and special anti-corrosive properties of all TAURUS shears, balers and shredders.

Thailand increases imports , the US increases exports

The recent trade statistics released by the Thai Customs Department suggests significant jump in ferrous scrap imports by Thailand during the month of April this year. The imports during the month were up by over 97% over the imports during the corresponding month a year before. The ferrous scrap supply from the US and Australia reported notable increase during the month.

According to Customs data, the totaled 108,019 metric tons in April this year. When matched with the previous month, the imports were up by 54.4%. Thailand’s ferrous scrap imports had totaled only 69,972 metric tons (mt) in March 2017. When matched with the same month a year before, the imports during the month were up by almost 97.3%. It must be noted that the country’s imports had totaled only around 55,000 metric tons in April 2016.

The key scrap supplier to Thailand during April this year was the US. The imports from the US totaled 72,515 metric tons, accounting for 67% of total imports by Thailand. The scrap imports from the US jumped mutifold from just under 1,800 mt in March this year. The second largest exporter of scrap to the country in April was Australia with 5,978 mt. The imports from Australia jumped higher by 103% upon comparison with the imports during March 2017. In third place was Dominican Republic with 3,036 mt. The other key exporters in April this year were Panama (1,831 mt), Philippines (1,711 mt), Trinidad & Tobago (1,672 mt) and the UK (1,355 mt).

For this reason the US ferrous scrap exports gain almost 28%

With the exception of South Korea and India, all major overseas buyers of US ferrous scrap upped their orders in the opening four months of 2017.

As a result, America’s exports to all destinations climbed 27.7% year on year from 3.113 million tonnes in the first four months of 2016 to 3.974 million tonnes by the same stage of 2017.

Turkey continued to lead the way, purchasing 857 499 tonnes in the January-April period for a year-on-year increase of 3.1%.

However, this gain was eclipsed by the surges in shipments to Mexico (+82.1% year on year to 542 774 tonnes), Taiwan (+55.2% to 485 329 tonnes), China (+381.4% to 309 407 tonnes), Vietnam (+1087.4% to 278 776 tonnes) and Canada (+147% to 222 320 tonnes).

Higher volumes were also dispatched from the USA to Thailand (+32.6% to 175 401 tonnes), Peru (+24.2% to 158 059 tonnes) and Bangladesh (+56.8% to 122 585 tonnes).

Also in this year’s January-April period, US ferrous scrap shipments to South Korea tumbled 38.6% to 202 509 tonnes while India’s purchases were slashed by 73.6% to 122 993 tonnes.

The Recycling of vehicles

An ELV or End of Life Vehicle still contains a significant amount of value due to its many valuable components. Many of these components can be reused to give the car a sort of “second life.” c must comply with the requirements of Legislative Decree no. 209 ELV recycling act from 24 June 2003 Directive 2000/53 / EC.

 

In Italy, more than 700,000 used cars come to the end of their life each year, and most of the components contained in these cars can be considered reusable. It goes without saying that many components are sold as spare parts or can be reconditioned, with as many parts as possible removed recyclers need only to process the body and chassis of the car

 

The first and most important part of the recycling process is to remove all liquids from the car; fuel; lubricating oil; cooling fluid, brake fluid, engine and gear oil are all cleanly removed using special tools and stored in certified canisters before being sent to specialist reprocessing factories for cleaning and reuse. All removed liquids are considered hazardous goods, as they can be highly toxic and damaging to the environment.

 

The lubricating oil once extracted from the car can be transformed into base oil´s or used in industrial plants such as cement factories where it is used as a fuel.

 

Aside from the removing liquid pollutants, batteries and tires must not be forgotten. The batteries are made from and contain heavy metals such as lead, chromium, cadmium, copper, zinc and mercury. Once they have come to the end of their life they must be recycled as they are highly toxic and dangerous to the environment. Car batteries are sent to specialist recycling centers while the waste tires are granulated and have their metal belts removed. The remaining rubber granulate is a valuable source of energy for energy-intensive industries.

 

Electrical and electronic equipment as well as lightbulbs can be collected and reused as they are without the need for reprocessing. If, on the other hand, they cannot be reused, then the glass components can be used to create fiberglass for insulating purposes or to create specialist tiles. The windscreen, front and rear side windows are all removed and shipped to specialist glass recycling factories.

 

The plastic components of a car include the: dashboard, door, bumper, windscreen wiper elements. However, the recycling process varies. Some parts are recovered and extracted before shredding, but others are separated after the shredding process.

 

The same applies to the metal content and in particular to steel and aluminum which can be recycled indefinitely without losing their special metallic properties. Seats and mats are also removed as they are mainly composed of elastomers, resins and or cellulosic materials, all of which can be effectively recycled. Larger easy to remove items such as seat cushions, mats and bumpers are removed before shredding while any remaining plastics are sorted using drum magnets and other specialist machinery post shredding.

 

TAURUS offers customers working in the car dismantling sector a wide choice of products and equipment to facilitate the complex process of  ELV cars recovery. Hammer mills from the Taurus Redline range including the M168J, are suitable to transform scrap cars in to high quality recycled materials. The DIABLO shear baler from the TAURUS BLACKLINE range and the TAURUS BLULINE shears and balers make light work of ELV chassis while the TAURUS REDLINE BRAVO pre shredder is the perfect machine to process entire cars with or without engine in a safe way without the risk of explosions.

The standard operation of a full sized shredder is not without risk of explosions. The high temperatures produced by the intense friction created during the shredding process will instantly igniting any flammables entering the hammer mill and could cause an explosion.

If the pre shredding process is omitted then inevitably partially filled or even empty car petrol tanks, gas tanks and LPG or BBQ gas tanks will enter the shredder chamber. As the mills hammers tear in to these tanks and release the gas or vapor an explosion will occur. These explosions can be quite sever and can cause damage to nearby buildings as well as being a major health and safety risk for the mill operator and other personnel.

 

During an overload situation the “press flap” returns to a neutral position to aid in freeing the material as both rotors spin in the opposite direction.

In this phase, the teeth of the low speed rotor tear the previously blocked material apart against the face of the “swinging-floor”. Grouser teeth in the swinging floor ensure the optimal positioning of the rotor teeth.

Once the blockage has been cleared, the rotors revert to their natural state of rotation to process the remaining material which was unable to be processed on the first pass.

In case of very dense scrap several passes may be required however this process can be repeated auto-matically without operator intervention until all the material has passed through the millfeeder (the number of cycles required to process heavy and dense scrap depends entirely on the torque and power available to the rotors).

At the end of the overload cycle, the “swinging-floor” returns to its normal operating position.

The operator can also choose to override the automatic cycle by adjusting the “swinging-floor” and the direction of rotation at his own discretion.

The contact surface of the “swinging-floor” is constructed of thick high strength wear resistant steel (HARDOX).

 

Grinding chamber of an Hammer Mill

 

Regardless of how much care is taken to sort hazar-dous from the scrap before feeding the mill, it is im-possible to completely remove all potential sources of explosion, especially if these sources are “ hidden” in auto bodies or bales.

 

By pre-shredding the material in a low speed shredder which uses teeth rather than hammers you can al-most entirely remove any explosion risks. Any petrol or gas tanks will be torn open at low speed and the po-tential explosive mix will harmlessly dissipate before reaching the hammer mill.

 

During normal operation of the pre shredder there is almost no chance of an explosion oc-curring due to the low speed of the rotors and the fact that the chamber of the pre-shredder is mainly open.

The different counter-rotating rotor’s speed, their position, number and shape of the teeth are all designed to harmlessly tear apart gasoline tanks and most gas containers.

 

Using a pre shredder such as the Bravo will give mill operators a distinctive economic advantage over shredder operators who chose not to pre shred their scrap. A quick return on investment and lower ope-rating costs of the main shredder are achieved due to:

 Lower energy consumption (even and optimal scrap fed to the hammer mill).

 Increased working life of the wear parts (hammers, grates, liners..)

 Lower maintenance costs due to the higher productive life of castings

 Lower service costs due to increased service intervals

 Less downtime associated with explosions and removal of “hidden” unshreddables.

 Allows smaller shredders operators to easily process bulky and dense material (such as bales) that otherwise could only be processed by larger more expensive machines.
