摘要：

Kinetic model of desulphurization incorporating transitory reaction in plume zone and permanent reaction at top slag-metal interface is applied to desulphurization by calcium carbide powder injection in 400 ton torpedoes at Hoogovens IJmuiden. Fraction of powder particles entrained in gas bubbles depends upon gas now rate. Overall increase in percentage desulphurization at higher gas now rates is primarily due to increase in the mass transfer coefficient in the bulk metal and in the plume region. Practical aspects of the effect of nozzle design on desulphurization in torpedoes are also discussed.
