Electric Furnaces with the Largest Production Capacity in the World
The Algerian project under construction of China Steel Equipment is the largest comprehensive steel mill for ironmaking, steelmaking and rolling under overseas general contracting of Chinese enterprises. Among them, the annual production of DRI is 3 million tons, that of steel-making and continuous casting is 2.15 million tons, and that of bar is 2 million tons. China Steel Equipment Centralized Advantage Team has overcome the difficulties of overseas construction and tight construction period, produced qualified products in the shortest time, achieved a number of world first, and created good economic benefits, which has been praised by the owner.
One 240t electric furnace is the main process equipment in the steel-making and continuous casting workshop of SISCO Algeria Project. 1 240t ladle furnace; 1 set of raw material treatment system (MHS), the main raw material for steel making is 100% H/CDRI; 1 8-Strands Continuous Caster with 180 Casting Sections × 180mm-200 × 200mm, fixed length 9-12m, arc radius R=10.25m. This project EAF is currently the world's largest electric furnace per unit capacity.
This project adopts the process flow of direct reducing iron-steelmaking-continuous casting-rolling steel, and adopts the process of direct reducing iron hot discharging, hot conveying and hot charging electric furnace in gas-based shaft furnace. Using DRI as raw material, 700-900 C direct reduction iron is heated to the high-level bin of electric furnace. It enters the electric furnace steel-making by continuous feeding. The power consumption per ton of steel can be reduced by 150kWh, the melting time can be shortened by 17%, and the capacity of electric furnace steel can be increased by more than 17%. The comprehensive cost of power consumption for high-speed bar rolling with 2-slitting is reduced by more than 15% compared with traditional non-slitting high-speed bar rolling.
