Inclusion Control

The hot metal fed converter in Panzhihua Steel Company is characterized by high sulfur content of 0.085% and high phosphorus content of 0.133%. Under this condition, some technologies like control of sulfur and T[O] content, ladle slag optimization, calcium treatment and protective casting were used in practice, and the desired result of T[O] as low as 0.0014% and sulfur content of 0.0023%was achieved, which met the cleanness requirements by anti-HIC X65 tube steel. With the help of inclusion control technology, grade of inclusions in as-cast steel was less than 0.5. In addition, total amount of inclusions was only 0.0044% which dispersed in slab in form of small spherical particle.

High Sulfur Content

In cognizance of the problems of low desulphurization rate for hot metal, large sulfur-recovery in converter, as well as high sulfur content in products when producing non-oriented electrical steel with vanadium-content hot metal, countermeasures have been carried out. Sulfur content in non-oriented electrical steel is decreased obviously with the study on technologies of desulphurization for hot metal with vanadium & titanium, sulfur-recovery control in converter, and desulphurization in RH refining process as well. The results of industrial tests show that the rate of w（S）≤0.008 % is as high as 100 %, and the rate of w（S）≤0.005 % reaches 91.43 %. And besides, sulfur mass fraction is 0.004 2 % on average (0.001 9 %~0.006 9 %).
