SLAB SURFACE TEMPERATURE CONTROL METHOD OF A TWIN ROLL STRIP CASTING PROCESS, WHICH CONTROLS THE SURFACE TEMPERATURE OF A SLAB

摘要

PURPOSE: A slab surface temperature control method of a twin roll strip casting process is provided to control the surface temperature of a slab within a 100°C.;CONSTITUTION: A slab surface temperature control method comprises: a step of directly forming two roll of castings from the molten steel(S10); a step of transferring the formed slab to a rolling mill through the loop pit of the inert atmosphere(S40); a step of rolling the slab transferred by casting a thin plate(S51); a step of controlling the atmospheric oxygen concentration of the loop pit to 0.1~5%; and a step of controlling the surface temperature of slab to 100°C.;COPYRIGHT KIPO 2010
