WIPO Patent Application WO/2015/099224

Kind Code:

A8

Abstract:

A hot rolling device, according to one embodiment of the present invention, may comprise: a cast part supply portion for producing a cast part; a hot roller, which is linked to the cast part supply portion, for receiving and hot-rolling the cast part; and a heating unit, which is arranged between the cast part supply portion and the hot roller, for reheating an outer surface portion in the widthwise direction of the cast part while latent heat is maintained in the center portion of the widthwise direction of the cast part from pre-heating. Also, a device for continuous casting/hot rolling, according to another embodiment of the present invention, may comprise: a continuous casting device for producing a cast part; a hot roller linked to the continuous casting device so as to receive the cast part; and a heating unit, which is provided at the front end of the hot roller, for repeatedly heating the cast part at a plurality of points so as to evenly heat the cast part. Also, a method for casting/hot rolling, according to another embodiment of the present invention, may comprise: a continuous casting step of producing a cast part; an even heating step of repeatedly heating the cast part from a plurality of points in the transporting direction of the cast part; and a hot rolling step of reducing the cast part after the even heating step.
