Not only can design a good workshop so that the blast furnace production to achieve high yield, long service life of the ironsmelting equipment, can also reduce energy consumption, cost savings, so as to achieve the goal of economic environmental protection, the design, from the design of blast furnace refractories. the design of cooling equipment and handling of slag and iron were borrowed from domestic and foreign advanced blast furnace. The design uses the hearth and bottom of the ceramic cup, copper stave heat load cooling equipment. The blast furnace cooling method using soft water closed loop cooling. Outlet platform casthouse rectangular double casthouse, four iron port balance arrangement, slag and iron ditch is reasonably arranged, and molten iron to swing stream mouth, a flat field of iron blast furnace equipment selection high degree of mechanization, the choice of the dust removal facilities to improve iron field operating environment.
