Abstract

PURPOSE:To improve the accuracy of a rolling stock by providing a mechanism, used for preventing the deflection of a work roll of one side and controlling the deflection of a work roll of the other side with respect to the horizontal direction, in case of using a mill as a five high mill. CONSTITUTION:Large-diam. work rolls 2, 3 are supported by backup rolls 6, 7, when a mill is used as a four-high mill. When the mill is changed into a five-high mill, small-diam. work rolls 4, 5 are incorporated into the outlet side 11 of the mill after extracting the work roll 2, and the roll 3 is used as an intermediate roll. At that time, intermediate rolls 12 and backup rolls 13 are provided to the small-diam. work rolls 4, 5. By this mechanism, the deflection of the roll 4 in the horizontal direction is prevented, and the shape of a rolling stock is controlled by advancing and retreating to/from the inlet side 10 of the stock. Accordingly, the accuracy of a rolling stock is improved.

A pair of horizontal bending prevention i-structures 8゜8 support the body of one small-diameter work roll on the entry and exit sides of the rolling equipment to prevent horizontal deflection, and the other supports the body of one small-diameter work roll to prevent horizontal deflection of the other small-diameter work roll. The large diameter work roll 2.3 is supported by the backup roll 6.7 and the horizontal bending adjustment mechanism 9 is provided, and when switching to four stages as shown in FIG. 2, the large diameter work roll 2.3 is supported by the backup roll 6.7 and When switching to 5 stages and using it, take out one of the large-diameter work rolls (the upper large-diameter work roll 2 in the figure) and offset the small-diameter work rolls 4.5 to the rolled material exit side 11 instead. The upper small-diameter work roll 4 is directly supported by the backup roll 6, and the other large-diameter work roll 3 is used as an intermediate roll to back up the lower small-diameter work roll 5 via the large-diameter work roll 3. The body of the lower small-diameter work roll 5 is supported by the roll 7, and the horizontal bending adjustment mechanism 9 prevents horizontal bending of the upper small-diameter work roll 4 by the horizontal bending prevention mechanism 8.8. The side 10 is pushed and pulled to adjust the amount of deflection and control the shape of the rolled material.
