Abstract
PURPOSE: To make the descaling treatment to adapt itself to variations of the line speed, in order to stabilize the operation, by installing the descaling apparatus comprising the scale breaker, the high pressure water jetter, and the brushing roll, on the feeding side of the cold rolling mill.
CONSTITUTION: On the feeding side of the cold rolling mill 7, the descaling apparatus comprising the scale breaker 4, the high pressure water jetter 5, and the brushing roll 6, is installed; the hot rolled steel sheet passed through the welder 2 and the looper 3 is introduced into this descaling apparatus, where the cracks are formed in the scale, and next, the scale is removed off by the high pressure water jet, and the remaining scale and foreign matters are removed off by the brushing roll 6; hereby, the sheet surface is cleaned, and the sheet is cold rolled by the cold rolling mill 7. As a result, the conventional pickling apparatus is unnecessitated, and the descaling treatment adapts itself to variations of the line speed, and besides, since the fluid mixture of iron sands or the like is not used, the early abrasion of the appartus is avoided, so that the operation is stabilized.
