Rh Why does it take so long to smelt silicon steel?

Reasons for the long time of rh smelting silicon steel;

The external refining of 1 and RH generally requires two or three fine-tuning of components to meet the target requirements.

2. When smelting IF steel and silicon steel, argon gas is blown at the bottom of the whole process, and the gas supply intensity is increased at the later stage to promote the steel slag reaction to further reduce carbon. In the process of smelting, the top oxygen lance changes from high to low, and the lower the C content at the end of smelting, the better.
