Description

Steel plate traction device {STEEL TRANSFER DEVICE}

TECHNICAL FIELD The present invention relates to a steel sheet traction apparatus, and more particularly, to a steel sheet traction apparatus for pulling down a steel sheet sandwiched between a feed roll.

In general, a hot rolling process in an ironworks is carried out by heating the slab 2 in a heating furnace 1 to a temperature suitable for rolling operation, for example, 1100 to 1300 ° C, as shown in FIG. Rolling is carried out with the rolling mill 4 while conveying through it, and the steel sheet 6 of the desired thickness is made through the accelerated cooling facility 5, again corrected by the hot straightener 7, and then lengthened by the cutting machine 8 It is made in the order of storing in the warehouse (9) in the state cut to fit the width.

By the way, when rolling the slab 2 which passed the heating furnace 1 to the steel plate 6 of the desired width | variety and length with the rolling mill 4, the temperature difference of the upper and lower slab 2 which is a rolling material, and the diameter difference of the upper work roll. Alternatively, a bending deformation occurs in which the tip of the rolled steel sheet 6 is bent upwards or downwards as shown in FIG. 2 due to various factors such as the speed difference between the upper and lower work rolls during rolling. Among such bending deformations, in particular, in the case of bending deformation bent downward, the bent tip hits the feed roll 3 and damages the equipment.

Such equipment accidents lead to enormous process losses (decreased productivity) due to the interruption of work and the repair and maintenance.

In order to solve this problem, the guide 10 is installed on both left and right sides of the rolling mill 4 at the point where the tip bent by the bending deformation is concentrated. When the tip of the bending deformation falls, it first collides with the guide 10 and then is transported. The roll 3 was combed to prevent breakage of the feed roll 3.
