METHOD FOR MANUFACTURING UNIFORMED STEEL BILLET IN TWIN ROLL TYPE STRIP CASTING

摘要

PURPOSE: A method for manufacturing uniformed steel billet in a twin roll type strip casting is provided which manufactures uniformed steel billet in the width direction of casting rolls by uniformly solidifying the steel billet in the width direction thereof to the utmost. CONSTITUTION: In a method for manufacturing steel billet using a twin roll type strip caster equipped with a cylinder part comprising a sleeve on the surface of which a coating layer (25) is formed; and two rolls comprising a shaft part connecting both side parts of the cylinder part, wherein the two rolls are oppositely installed, the method comprises the process of performing the casting by pre-processing the surface of a sleeve (23) that is excluded as much as a width of the hot band of steel billet from the edge, and installing an electric heat hindrance layer (26) having less heat conductivity than the sleeve at the processed surface of the sleeve.
