Abstract
PURPOSE: To prevent crack formation in the surface of rolls, by, in hot rolling of the sintered compact made of a high melting metal such as W, Mo, forming the portions of press. rolls, which contact with the material to be rolled, with a tool steel of specific material.
CONSTITUTION: The surface portions of three rolls 1, which hot-roll a sintered compact of a high melting metal such as W, or Mo, is made of a tool steel, e.g., SKD 6, SKD 61, SKT 1W6 etc. defined by JIS. The sintered compact W, Mo, etc. placed in the space formed between the three rolls 1, which rotate around the axes 1a, is hot-rolled by the rotation of the three rolls at a temp. of 1,200W1,400°C. During rolling, no crack is formed in the surfaces of the rolls, so that the rolls long lives.
