| Abstract: | This paper describes the transformation of the optimization process of cold heading steel SWRCH22A steelmaking in Shougang Shuicheng Iron ＆ Steel Co. Those optimization measures can be taken for serious molten steel resiliconization phenomenon and unstable castability, the average resiliconization amount of SWRCH22A in Shougang Shuicheng Iron ＆ Steel turns from 0.04% to 0.02% ,the number of continuous casting furnaces turns from 2 to 7. Practice has proved that Shougang Shuicheng Iron ＆ Steel has been fully equipped with the ability to produce quality SWRCH22A. |
