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,采用可以有效地解决铁液的问题。

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“高拉补”、炉后工艺，转炉能够冶炼出合格的高钢。

Using carburizing agent and devulcanized agent,experiment of carburisation and desulphuration for semisteel which in smelting high titanium slag by electric cooker has been studied.

用脱硫对冶炼高钛渣副产半钢进行了脱硫试验研究。

The semisteel after the treatment can be used in cast iron and it has a good economic effectiveness.

半钢经过脱硫处理并合金化可以用作铸造生铁,而且有较好的经济效益。
