Abstract
According to production condition of an 180 t oxygen converter
the hydraulic simulation test of 1/15 model of oxygen top blown converter has been carried to get the effect of blown process parameters on bath. Results showed that as top blown gas flow rate was m 15.5 m
3
/h the change of oxygen lance position and gas flow rate have little influence on mixed time of bath; with lowering top lance position and increasing top blown gas flow rate the splash amount of bath increased ;and as gas flowing rate was 16.0 m
