RH DegasserlRH Refining Furnace

August 02, 2018

With R&D of vacuum steel-making technology, from 1970s, the RD furnace starts to appear as the continuous casting arises. Because taking the technology of steel liquid is circled in the vacuum tank in the RH furnace, then reached short -time, high-efficiency, matched with the converter continuous casting etc. features,then RH furnace has been widely used in the converters.

 

RH Refining Furnace

Through RH treated, the steel has below obvious features:

1) Alloy basically did not act with the slag,

2) Alloy is added into the steel liquid directly, high recovery efficiency,

3) Steel liquid can be Quickly and evenly mixed,alloy part can be controlled within the narrow scales

4) Lower gas content, few impurity, high purity of steel liquid,

5) Also adjust the temperature in the chemical way temperature rising with top lance, supply the fine flowing, high purity, accord with the casting temperature’s steel liquid, to good for the many times of furnace casting in the continuous casting production process.
