Mathematical modelling of the thermal regime of a ladle- furnace unit considering internal heat sources

We apply mathematical modelling to study heat transfer processes during fire refining of blister copper in a ladle-furnace unit. A unit was designed test the technology using bottom blowing bubble mode by gaseous reducing agents (hydrocarbons) and an oxidiser. Mathematical allows properties real process be described based on formalisation physical laws regularities. It proposed use agents, rather than expensive residual fuel, as liquid-reducing agent. The produces higher technical economic indicators process. In addition, some technological operations were transferred directly ladle, thereby eliminating need for re-melting heating refined copper. One identified problems maintain predetermined thermal regime, which provides very possibility both performing introducing reagent (determining hydro-gas-dynamic parameters) into melt blowing. An original method considering effects chemical reactions models presented example exothermic oxidative refining. two different methods analysis allowed comprehensive assessment influence main regime can used determining specific effect various parameters (composition fuel consumption, temperature degree blast enrichment, lining design, etc.) dynamics changes field melting whole.
