Mass transfer coefficients in metallurgical reactors

An overview on the application and achievements of physico-mathematical modeling of metallurgical processes in China is briefly declared. The important role of coefficients in model formulation is shown from our experience. The mass transfer coefficients of the slag-metal reactions and the gas-metal reactions are discussed referring to the flow conditions near the interface. The influence of the surface-active species on the mass transfer and the inteffacial reaction is also discussed briefly.
