OREANDA-NEWS. January 16, 2013. The successful hot commissioning of 350000 ton road base materials production line in early of Dec. 2012 and 1 million ton stainless steel slag co-product wet treatment line a few days ago in the first phase project of TISCO-HARSCO Technology Corp. Ltd. marked that the project construction has made substantial progress, the two production lines have entered into trial production and laid a solid foundation for the full operation of the whole project, reported the press-centre of TISCO.  
   
TISCO-HARSCO Technology Corp. Ltd. is equipped with the internationally advanced equipment and adopts the most advanced steel slag treatment technology. The total project investment is 1 billion yuan. Its construction started in March 27, 2012. The first phase of the project consists of 1 million ton stainless steel slag co-product wet treatment line, 350,000 ton road base materials production line, 500,000 ton stainless steel slag co-product drying and fertilizer production line, 300,000 ton carbon steel slag crushing and super fines production line and 100,000 ton Performix (additives for steelmaking) production line.
   
After the stainless steel slag co-product wet treatment line is operational, it will separate the residual metals in the slag from the slag co-product; the recovered metals will be used as raw materials for steelmaking, the slag co-product as fertilizer, which laid a solid foundation for the stainless steel slag co-product drying and fertilizer production.
   
The trial production of the road base materials production line shows that the new, high grade and high strength road base materials produced by TISCO will be launched on the market. Comparing with conventional road base materials, these materials can save 6% cement, their strength and elasticity is higher and the pavement cracking can be effectively prevented.
   
The first phase of the TISCO-HARSCO Technology Corp. Ltd. will be put into operation at third quarter of 2013. The annual sales revenue will be about 470 million yuan. At that time, it will be the largest fertilizer and relevant metallurgical co-products production base with the whole processes and most advanced technologies in the world steel industry; the steel slag generated during steelmaking in TISCO will be fully efficiently reused and zero waste discharge will be achieved. It is the trend-setter in steel slag treatment in China and will play a demonstration and leading role in steel slag recycling for steel plant.
