发明名称	METHOD FOR ROLLING SHAPE STEEL AND METHOD FOR PRODUCING SHAPE STEEL
摘要	PROBLEM TO BE SOLVED: To improve the surface quality of a shape steel product by suppressing the seizure between a roll and the material to be rolled in shape steel rolling, and to improve rolling efficiency by preventing the spalling of the roll in the shape steel rolling operation. SOLUTION: In the method for rolling shape steel, a roll comprising a ferrous material as an external layer, and a cemented carbide layer at the inside is used. The method for producing shape steel uses the method for producing shape steel. COPYRIGHT: (C)2006,JPO&NCIPI
