Practice on recycling and utilization of the residual slag from continuous casting
The comprehensive utilization rate of the casting residue in most steel mills is only 10％.The Xichang im-provement is part of the hot casting residual slag is recovered to LF for refining slag,part is returned to is returned to vanadium/steelmaking BOF,part is used to hot split blocks.The cooled residual tailings are used to make molten steel refiner,which realizes the self-circulation of the casting residue resource plant,and realizes the value apprecia-tion of the residual residual tailings,energy saving and low-carbon emission reduction.
