摘要

ferrous metallurgy; steel making processes. SUBSTANCE: pig consists of layer of aluminum and layers of cast-iron. It has steel envelope with aluminum and cast-iron layers enclosed inside it. Aluminum layer is located asymmetrically between layers of cast-iron in center portion of pig. Ratio of aluminum mass to cast-iron mass is equal to 1?1.5-8.5). EFFECT: reduced burning losses of aluminum; improved quality of steel. 1 dwg
