OVEN FOR MELTING in a liquid bath of materials containing nonferrous, ferrous metals and refractory EDUCATION

摘要

FIELD: metallurgy.;SUBSTANCE: furnace consists of caisson shaft divided with cross partition into melting and reducing chambers equipped with low and upper tuyeres, of sole, of siphon for accumulation and tapping metal and slag via corresponding channels with orifice in lower part of end wall, of device for loading charge and solid materials into melting and reducing chambers and of pipe for fume extraction. The siphon is equipped with at least one bushing for insertion and transfer of an electrode in it, with a block for electrode manipulation, with a power source, and with a block of control-measuring facilities and automation. Also an upper part of the electrode is connected to the power source and to the block of control and measuring facilities and automation; the output of the latter is coupled with an input of the manipulation block ensuring vertical reciprocal motion of the electrode via its drive and its deviation from vertical axis.;EFFECT: ensuring long-term furnace operation maintaining minimal level of mechanical losses of metals and increased safety and reliability of operation.;8 cl, 1 dwg
