By way of “raising high carbon content and post blowing” as well as recarburization practice can the high carbon steel of fine quality be refined in the converter.

通过“拉补吹”、炉后增工艺，转炉能够冶炼出合。

When melting cast iron f or rollers in main frequency induction furnace,the recarburization of the molte n iron could be effectively achieved by using new types of recarburizer.

用工频电炉熔炼铸铁轧辊时,采用新型增剂可以有效地解决铁液增问题。
