Product Details
Direct reduction ironmaking method
◇Tunnel kiln method: 10,000 to 50,000 tons
(Has been phased out)
◇Rotary kiln method: 30,000 to 200,000 tons
(Low investment)
◇Blast furnace melting method: 100,000 to 800,000 tons
(High investment, the pre-reduction process of rotary kiln is still needed before entering the furnace)
Direct reduced iron is a non-blast furnace ironmaking technology. It is a non-blast furnace ironmaking technology (encouraged) in the national industrial structure adjustment. Direct reduced iron is a direct raw material for special steel and powder metallurgy, and it is a necessary diluent for scrap steelmaking.
Due to the various drawbacks of long-process blast furnace ironmaking, with the abundant accumulation of scrap steel resources, short-process electric furnace steelmaking has gradually developed into the mainstream, and the demand for reduced iron will greatly increase. Relying on a professional technical team and strong processing capabilities, Dingzheng Group leads the country in the direct reduction technology of rotary kilns MER is devoted to the innovative research and industrial application on the energy-saving, high-efficiency and purification technology on the calcination and smelting of industrial furnaces, casting pipe/pressure vessel process and the energy recycle. Our R&D technical level has taken as one leader in China. The R&D team has proper professional structure which covering process, thermal tech, casting, machinery, EIC, material, civil construction, steel structure…
