Abstract

The invention discloses an entry loop mechanism and system and a continuous annealing line loop control method. The entry loop mechanism and system and the continuous annealing line loop control method are applied to the technical field of steel rolling. The entry loop mechanism comprises a loop bottom roller, a bearing, a bearing seat, a pneumatic performing mechanism, a band-type brake roller, a base and a connection rod. The bearing seat is arranged in the roller side face position of the loop bottom roller. The band-type brake roller is assembled in the bearing seat through the bearing. The bearing seat is fixed to the first end of the connection rod. The second end of the connection rod is hinged to the base. A fixed part of the pneumatic performing mechanism is connected to the base. A movable part of the pneumatic performing mechanism is hinged to the second end of the connection rod. The technical problem that in the prior art, after strip steel in an entry loop is broken, a strip head is sucked in an annealing furnace is solved, and the fault handling time is shortened greatly.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to an inlet looper mechanism, a system and a method for controlling the looper of a continuous withdrawal line. Background technique [0002] The continuous annealing unit is an important link in the production of cold-rolled strip steel. It has a series of advantages such as short process, high output, and good product quality. It is an indispensable annealing equipment. The entrance speed of the high-speed continuous annealing line is fast. When producing thin-gauge strip steel, belt breakage often occurs in the cleaning section and the entrance looper. For example, the 1420 continuous withdrawal line has a maximum design speed of 1000m / min at the entrance, a maximum speed of 750m / min in the furnace area, and a maximum speed of 1100m / min at the exit. Belt breaks often occur in the cleaning section and the inlet looper during production. [0003] Currently, the brake block ...
