Abstract
PURPOSE: To titled apparatus made possible to effectively descale, by arranging the brushing roll behind the differential rolling mill.
CONSTITUTION: In the said differential rolling mill 5, the upper roll 5-1 and the lower roll 5-2 are rotated at different circumferential speeds. Hence, a horizontal stress due to the tension is caused in the hot rolled steel sheet S passed through the gap of upper and lower roll 5-1, 5-2; this horizontal stress causes cracks in the scale covering the steel sheet S. Moreover, when the hot rolled steel sheet S is wrapped around upper and lower rolls 5-1, 5-2, a bending stress is caused in the steel sheet S by the bending work, and hereby, the descaling effect is increased. The brushing roll 6, installed on the run-out side of above stated differential rolling mill 5, perfectly removes the scale crushed by the mill 5 from the surface of the hot rolled steel sheet S, by touching the surface of steel sheet S so as to grind it. As the material of the hair of the brushing roll 6, nylon, etc., including abrasive grains is employed.
