Blast furnace is a multi-functional smelting Coal preparation aims at the production of coke of suitable quality for smooth and stable blast furnace operation. The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides. Interpretación Traducción  blast furnace. The slag formed consists of the limestone flux, ash from the coke, and substances formed by the reaction of impurities in the ore with the flux; it floats in a molten state on the top of the molten iron. The preheated air reacts vigorously with the preheated coke, resulting in both the formation of the reducing gas (carbon monoxide) that rises through the furnace, and a very high temperature of about 1,650° C (3,000° F) that produces the liquid iron and slag. Blast furnace has been used for iron/copper/copper -nickel/zinc/lead and zinc-lead complex concentrate smelting for a long time. In Europe, the blast furnace developed gradually over the centuries from small furnaces operated by the Romans, in which charcoal was used for reducing ore to a semisolid mass of iron containing a relatively small amount of carbon and slag.
