Abstract
PURPOSE: To reduce the amount of removal due to scarfing and to improve the yield, in the automatic scarfing method for the surface of the high temperature metallic material after the rought rolling, by varying the traveling speed of the material to be scarfed, and by carrying out the variation control of the amount of scarfing.
CONSTITUTION: When the slab S of thickness t0 is scarfed by the scarfer 4, the amount of scarfing Δt' for the bottom zone l (generally 2m) is set at 1.5W2.0mm; this amount of scarfing is successively reduced, so as to set the general amount of scarfing Δt at 0.5W1.0mm which is then applied to the whole. As a result, the amount of scarfing is reduced as compared with the amount of scarfing for the whole surface Δt' depending on the conventional method, and then, the yield is improved. Above controlling means is constituted as follows; the amount of scarfing is set at the controller 3 which is given the input from the position detector 1 and the temperature detector 2 installed on the traveling line of the slab S, and the control is carried out so as to give the feed speed suitable for the set value to the scarfer 4 through the motor 5 for driving the slab S.
