Research on Recycling Technology of Returning Hot Casting Residual Steel Slag to Converter
In order to make full use of the residual steel slag and reduce environmental pollution,the steel-making plant of Angang Steel Co.,Ltd.has researched on the recycling technology of the RH and LF residual steel slag of the No.4 branch plant to realize the return to the converter or to the LF refining furnace,and proposed and realized the smelting technology of the converter with the addition of casting residual steel slag for the first time.By returning the RH and LF cast residual steel slag to the converter in a hot state,the rapid slag formation and efficient dephosphorization of the converter in the early stage are realized,which saves the slag consumption and oxygen consumption,and shortens the converter processing time.
