Abstract
With micro-sintering experiment, using single factor research to study the dephosphorization agents and process parameters on the impact of high phosphorus slag and internal mechanism during sintering dephosphorization rate. The study find that the rate of gasification dephosphorization of slag modified by the dephosphorization agent mixed with C

which corresponding compositon was 0.18%, 0.29% and 0.69%, can be up to 40.5%. In the mixture for dephosphorization agent, the alkalinity of sinter mixture control in 1.0, with a carbon control at 4.0%, the sintering temperature control at 1350°C, dephosphorization effect is better when the phosphorus content is higher, but while the phosphorus content reach to certain content, the influence of phosphorus content becomes weak.
