A high temperature sealing component

Abstract

The invention provides a high-temperature seal assembly. The high-temperature seal assembly comprises a base plate and a plurality of seal blocks. The base plate is a round isolation plate, a round through hole is formed in the circle center of the base plate, the seal blocks are arranged on the base plate along the circumference, the seal blocks are composed of seal block bodies and backing plates, the seal block bodies are ceramic fiber specially-shaped folding blocks, the backing plates are specially-shaped fiber backing plates, the specially-shaped fiber backing plates make contact with the base plate, the seal blocks are fixedly arranged on the base plate, a round baffle is further arranged on the base plate, and the baffle is connected with the seal blocks internally and is in clearance fit with the seal blocks. According to the high-temperature seal assembly, existing heat-resistant seal materials are replaced by the seal blocks formed by the ceramic fiber specially-shaped folding blocks and the specially-shaped fiber backing plates, therefore, expenditures can be cut down, cost can be reduced, meanwhile, the service life of equipment can be prolonged, and losses, caused by equipment replacement and the like, in manpower, material resource, yield and the like are reduced accordingly.

Description

technical field [0001] The invention belongs to the technical field of heating devices, and in particular relates to a high-temperature sealing assembly. Background technique [0002] On continuous annealing furnaces, disc rollers and their supporting components are generally installed between different heating sections to ensure that the strip runs while reducing sag without damaging the strip surface. In the production process, the position of the disc roll can be switched by the disc roll changer equipment without affecting the continuous production of the unit, so that the fiber roll or ceramic roll can be replaced quickly on-line, but when the position of the roll is wrong or other failures occur, the heating furnace It will automatically alarm and switch to safe mode, causing the unit to stop, affecting production output and quality. The sealing device of the disc roller changer is to ensure the balance of heat in the furnace and reduce its loss. [0003] When the an...

AI Technical Summary

Problems solved by technology

[0003] When the annealing furnace disk roll changer equipment of the cold plate annealing pickling unit was put into operation, the original design of the stainless steel sealing curtain was burned and deformed, and the fiber support roller and the disk roll changer were jammed many times. Not only caused the cold line unit to stop many times, but also damaged the uploading tool, which seriously affected the normal operation of the cold line and increased the production cost
