Document Type and Number:

WIPO Patent Application WO/2016/104865

Kind Code:

A1

Abstract:

A rolling method according to one embodiment of the present invention may comprise: a rolling step for screwing down a supplied slab; and a heating step, performed prior to or during the rolling step, for heating the slab by placing a heater in the travel path of the slab immediately after a spot of the slab at which the height of the slab uniformly converges passes through the position of the heater in the travel direction of the slab, wherein the heater elevates or retains the temperature of the slab. A continuous casting rolling method according to another embodiment of the present invention comprises: a continuous casting step for producing a slab; a rolling step; and a heating step, wherein the heating step places a heater in the travel path of the slab immediately after the initial spot of the slab at which the height of the slab in the direction perpendicular to the travel direction of the slab begins to be constant passes through the position of the heater in the travel direction of the slab. In addition, another embodiment of the present invention suggests a continuous casting rolling device for performing the aforementioned method.
