Embodiment Construction

[0013] refer to figure 1 , 2 , a side guide plate of a coiler, comprising a side guide plate body 1 and a liner plate 2, and an arc-shaped guide groove 3 is provided near the lower end of the liner plate. Arc-shaped guide groove 3 is to utilize on the former take-up side guide plate backing plate to realize with the guide hole pattern of planer processing certain radian. The thickness is 60mm; the width is 150mm, the distance between the lower edge of the arc pass and the bottom of the liner is 10mm; the arc is an arc with a radius of 37, the arc depth is 25mm, and the opening of the arc pass is 70mm; the arc pass curve formula is: Y = 1369 - X 2 , X ∈ [-35, 35].

[0014] After the strip is finished rolling, the head of the strip first enters the slanted part of the side guide plate of the coiler, and due to the existence of the arc guide pass, the strip grad...

Abstract

The invention relates to a steel rolling side guide plate, in particular to a side guide plate of a recoiling machine, aiming at solving the technical problems of unsteady through plate of a current recoiling machine and liner wear of the side guide plate of the recoiling machine. The technical proposal of the invention is as follows: the side guide plate of the recoiling machine comprises a guide plate body and a liner plate, which is characterized in that an arc-shaped guide slot is arranged near the lower end of the liner plate. The inner concave surface of the arc-shaped guide slot is an arc-shaped curve, the formula of the arc-shaped curve is as follows: Y=square root (1369-X), X is an element of a set [-35, 35]. A hard alloy layer can be bead welded on the concave surface in the arc-shaped guide slot.

Description

Technical field: [0001] The invention relates to a steel rolling side guide plate, in particular to a coiler side guide plate. Background technique: [0002] The surface of the liner of the side guide plate of the coiler is easily ground out of grooves during the production process, and the grooves are uneven and irregular due to the influence of rolling thickness, steel type and plate shape. After the strip steel enters the side guide plate, due to the irregular grooves affecting the stability of the strip steel running, in hot rolling production, the strip steel plate shape sometimes has sickle bends, S bends, etc., and these strip steel runs under the clamping of the side guide plates Unstable, often jumping back and forth on the side guide plate, which has a bad effect on the coil shape and the edge of the strip. In order to increase the stability of the through plate during production, this situation is generally improved by increasing the clamping force of the side gu...
