在复吹炼钢条件下,研究了从炉顶和炉底同时向熔池喷入气体时,熔池的混合程度及其对传质的影响。传质过程的速率常数是用来表示熔池的混合程度及其与气体引起的搅拌能有着较好的伴随关系。这表明在混合吹炼过程中,熔池的混合程度可以单独地由顶部和底部气体喷吹参数来控制。 Under the conditions of complex blowing steelmaking, the mixing degree of the molten pool and its effect on mass transfer were studied when the gas was injected into the molten pool from the top of the furnace and the bottom of the furnace simultaneously. The rate constant of the mass transfer process is used to indicate the degree of mixing of the bath and its accompanying relationship with the gas-induced stirring. This indicates that during the mixing blow, the degree of mixing of the bath can be controlled individually by the top and bottom gas injection parameters.
