发明名称 METHOD AND DEVICE FOR CORRECTING POINT BEND OF ROLLED STOCK AND HOT STRIP ROLLING EQUIPMENT
摘要 <p>PURPOSE:To correct the point bending of a rolled stock in a hot rolling time without time loss and influence to productivity by stop of a rolling mill, securely, without requiring a complicated device and a control means, in a simple constitution, economically and practically. CONSTITUTION:The upward camber of a bar material 30 rolled by the rolling mill 2D is corrected by vertically movable horizontal rollers 15 and the point of the bar material 30 having a point bend is brought into contact with one of a pair of vertical guide rollers 10 set to an opening a little larger than the width of the bar material 30 and the bend part of the point of the bar material 30 is bent by the reaction from a vertical roll of a thrust given by the rolling mill 2D to the bar material 30 to the direction opposite to the bend part to be corrected. Moreover, the vertical roller 11 is driven and rotated by a motor 11 to relieve a shock when the bar material 30 comes in contact with the vertical roller.</p>
