Abstract
PURPOSE:To prevent steel material from temp. drop in transporting and to eliminate the generation of crack and malformation by sticking a heat insulating material on the surface of said materials being in high temp. CONSTITUTION:In a direct rolling of a steel ingot from a soaking pit or cast billet by continuous casting, a heat insulating material of small heat conductivity and high porosity is stuck on a part of the surface being likely to cool, of steel stock 1 of high temp. with bonding agent of inorganic group for high temp, <1,200 deg.C m.p., and is transported to the rolling process. At this time, the heat insulating material is stuck on the front surface of the stock 1 by a clamp 5 and a rotary blowing device 9, or by hand with the aid of a clamping tool and a press-contact tool. Thus the stock is transported to the rolling process to be rolled, but when the insulating material is an obstacle to the hot rolling, the material is stripped off with a functionally strengthened high press. descaling device, a scraper, a totary roller, and a press-pushing roller at the feed-inside of the rolling mill.
