Field manual correction device and correction method for continuous annealing furnace

Abstract

The invention relates to a field manual correction device and correction method for a continuous annealing furnace, and belongs to the technical field of production equipment for cold-rolled strip steel in the metallurgical industry. The following technical scheme is adopted: one end of each of two transmission rods (1) which are arranged in parallel is fixed to a connection plate (16); a jack (4)is in drive connection with the connection plate (16); the other end of each of the two transmission rods (1) which are arranged in parallel is fixedly connected with a correction disc (6); a strip steel guide plate (7) is arranged on the correction disc (6); a V-shaped groove is formed in the strip steel guide plate (7); a scale (8) is arranged on each transmission rod (1); and each transmissionrod (1) is fixed to a support (5) through a location ring (17). The field manual correction device and correction method have the following beneficial effects: strip steel which is seriously deflected and even hung onto a furnace wall in the continuous annealing furnace can be manually recovered to a normal position in the field in the case of not opening the annealing furnace, so that the accident handling time is greatly shortened, and lots of energy consumption caused due to blow-in of the annealing furnace is avoided.

Description

technical field [0001] The invention relates to an on-site manual deviation correction device and a deviation correction method for a continuous annealing furnace, and belongs to the technical field of cold-rolled steel strip production equipment in the metallurgical industry. Background technique [0002] The continuous annealing production line is a production unit mainly producing cold-rolled sheets, and the continuous annealing furnace is the key equipment for re-annealing the cold-rolled sheets. The continuous annealing furnace usually adopts a fully enclosed furnace structure. The furnace is filled with a reducing atmosphere of hydrogen and nitrogen mixed to form a protective gas, which is used to isolate the air and prevent the strip steel from being oxidized in the continuous annealing furnace. The strip steel in the continuous annealing furnace is driven by the furnace roller under tension to complete the entire annealing process. The thickness of strip steel produ...

Problems solved by technology

This method of starting the furnace to deal with the production accident of the strip steel colliding with the furnace wall is inefficient, time-consuming, and consumes a lot of nitrogen, which cannot meet the actual production needs of large-scale continuous annealing furnaces.

It consumes a lot of manpower, material resources and time, which brings great inconvenience to efficient production
