Abstract
BOF process is one of the most productive ways of steel manufacturing. Byproducts of this process are metallurgical slag, gases (volatile-rich oxide and other chemical compounds), metallurgical dust, and excessive heat. Nevertheless there are developed a large number of waste gas cleaning systems and recycling technologies, these factors still have negative impact on whole biosphere. The greatest effect it makes on the atmosphere since during melting, a substantial amount of carbon and nitrogen oxides are released into the environment. The steelmaking dust can be classified by its origin. The main types of waste dust include: fragments of the raw material (as a result of technological overload and crushing of the raw materials), products of evaporation and condensation (vaporized molten slag and graphite ripe). For their capture in conditions of Ukrainian manufacturing developed a number of specific technological schemes involving precipitation of dust component in special units (Venturi tubes, cyclones, and scrubbers). Their use can reduce the concentration of hazardous substances and to the regulated legal framework limit.
