Abstract

The invention discloses a sealing device for an inlet of a continuous annealing furnace, and belongs to the technical field of cold rolling. The sealing device comprises a furnace shell, an upper furnace door, an upper sealing roller, a furnace door lifting device, a lower furnace door, a lower sealing roller, a base plate, an in-furnace roller, a flat plate, a sealing curtain, a sealing box, a baffle plate bracket, a connecting rod and a baffle plate lifting device. The end surface flange of the furnace shell and the upper furnace door are separately connected with the base plate through bolts; the angle of inclination of the flange is 5-7 degrees; the lower sealing roller is connected with the lower furnace door through a bearing; the sealing box is mounted on the top of the furnace shell; and the connecting rod is connected with the baffle plate lifting device through a connector. The sealing device has the advantages of being simple in structure, low in cost, good in sealing property, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of cold rolling, in particular to a sealing device at the entrance of a continuous annealing furnace. In particular, it relates to a sealing device for the entrance of a continuous annealing furnace. Background technique [0002] In order to meet the requirements of customers for the internal structure and performance of strip steel, steel mills generally use annealing furnaces to anneal coils, especially continuous annealing units, which have been adopted by most cold annealing units due to their short production cycle and high product quality. Rolling mills use. In such a continuous annealing furnace unit production line, in order to ensure the stability of the gas composition in the furnace, the production personnel often use sealing rollers to seal the furnace entrance at the entrance of the annealing furnace. Because there is a certain gap between the sealing roller and the steel strip, the protective...
