摘要: A mathematical model of the nickel converter has been developed. The primary assumption is that three phases in are thermal and chemical equilibrium. All matte, slag, gas brought to equilibrium at end each a series short time steps throughout an entire charge. An empirical both matte slag used characterize activity coefficients phase. Two sulfide species were allow for modeling sulfur-deficient mattes. heat balance carried out over step, considering major flows converter. was validated by detailed comparison with measured data from six industrial charges. overall predicted mass shown be close seen actual practice, gave good fit temperature up last two or blows At this point, reactions begin deviate strongly “equilibrium,” probably due coming under liquid-phase mass-transfer control. While does work, it not strictly valid, majority charge gas-phase
