Guiding device, welding device and continuous annealing device

Abstract

The invention discloses a guiding device and a welding device for guiding a strip head of a cold hard roll to a welding machine for welding, the guiding device comprises a support, a first driving assembly and a guiding assembly, and the guiding assembly and the first driving assembly are both arranged above a guide plate table used for allowing a cold hard roll to pass through by the support; the guiding assembly comprises a driving roller, a driven roller, a belt and electromagnets, the first driving assembly is connected with the end of the driving roller, the driving roller and the driven roller are rotatably arranged in the width direction of the cold hard roll, the belt is annularly arranged, the middle of the driving roller and the middle of the driven roller are in transmission connection through the belt, and the electromagnets are arranged between the driving roller and the driven roller in a clearance mode, and the electromagnets are arranged in the belt in a clearance mode. The device solves the problem that a welding machine can hardly match and weld the tail of a former cold hard roll and the head of a latter cold hard roll due to the fact that the head of the latter cold hard roll is easy to break on a guide table, and meanwhile, the potential safety hazard caused by manually knocking the break angle is completely eradicated.

Description

technical field [0001] The invention belongs to the technical field of strip steel cold rolling annealing, and in particular relates to a guiding device, a welding device and a continuous annealing device. Background technique [0002] After the hot-rolled strip is cold-rolled, a chilled coil is formed, and the chilled coil needs to be annealed in a continuous annealing process to eliminate internal stress. In the actual production process of the chilled coil, due to defects on the surface of the chilled coil of the steel coil, it is necessary to cut the coil. Welding followed by annealing. [0003] At present, a welding machine is arranged between the continuous annealing furnace and the uncoiler, and the tail of the chilled coil of the previous coil set in the continuous annealing furnace is on the welding machine, which needs to be connected with the tail of the chilled coil of the next coil on the uncoiler. Welding, during welding, the head of the last coil of chilled ...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides a guide device, a welding device and a continuous annealing device, which solves the problem that the welding machine is prone to kinks on the previous coil caused by the bending angle of the head of the latter coil on the guide table. The problem that it is difficult to match and weld the tape tail and the tape head of the next chilled roll, and at the same time eliminate the safety hazard caused by manual knocking on the corner
