OREANDA-NEWS. November 09, 2011. TISCO trial production for metallurgy de-dust ash recycling project has got a major breakthrough. The first heat of nickel chrome molten iron was successfully smelted; via examining all the indexes reach the project goals. Compared with ordinary hot metal, the chrome nickel molten iron can add value above 5000 yuan per ton, reported the press-centre of TISCO.
 
Since trail production of Metallurgy de-dust ash recycling project was started on July 16th, it has already smelted out 25,000 tons of carbon steel, the materials are mainly solid carbon steel waste. The raw material of chromium nickel produced this time is solid stainless steel waste, production of the molten iron chromium and nickel content and stainless steel is very close to stainless steel molten iron, which can be directly used for stainless steel smelting, and shorten the steel making time and reduce the cost.

Success of Nickel chrome molten iron by shaft furnace smelting is the world's first. In order to overcome this worldwide technical problems, TISCO organized research group and carried out a lot of prophase research and test, after two years of scientific research by technical personnel, they gradually grasp the process characteristic of nickel chrome molten iron smelting in the shaft furnace, by all those above efforts, the trial production of nickel chrome molten iron get one-time success.??
 
Chromium and nickel are the necessary of precious metal for stainless steel production, which are containing in large amounts in solid waste during stainless steel smelting. TISCO is a steel company which mainly on stainless steel production, each year nearly million tons of chromium and nickel contained solid waste need to be treated, efficient recycling this part has a great significance for TISCO.
