摘要：
Mintek has applied DC arc furnace technology to the reductive smelting of numerous materials over more than three decades. The first industrial implementation of this technology was for the smelting of chromite fines to produce ferrochromium in 1984. Since 1985, process simulation has been carried out using Pyrosim and FactSage software to study this process. Some examples are presented of the mass and energy balances and thermodynamic calculations used for the steady-state simulation of chromite smelting for the production of ferrochromium. There is a place for equilibrium calculations involving non-ideal slag and alloy solutions, as well as for empirical models that can be used in an operating plant environment. (C) 2016 Elsevier Ltd.
