Abstract
PURPOSE: To prevent the generation of cracks in the surface of a sheet product, by hot-forging a sintered blank comprising such a high melting point metal as W or Mo into to sheet blank, and then, by hot-for ging the edge of this sheet blank in order to deform it into a wedge shape, and by hot rolling this wedge shape blank.
CONSTITUTION: A powder of such a high melting point metal as W or Mo is press- formed into a compressed powder blank which is then baked in a hydrogen atmosphere; an electric power is then conducted across this baked blank which then generates a resistance heat and is sintered thereby. This sintered blank is again heated in a hydrogen atmosphere and is subjected to a hot forging pass; hereby, the blank is deformed into a wedge shape with a taper angle of about 20 degrees after once passing a sheet shape. This wedge shape blank is heated in a hydrogen atmosphere and is hot rolled into a sheet shape. By the present constitution, any creack does not generate in the surface of the sheet product so that the rolling yield of the sheet product is improved.
