Description

Technical Field

[0002] As competition in the steel industry becomes increasingly fierce, each company is developing high-end products with its own advantages to meet market demand. Under the general trend of energy conservation and emission reduction, the automotive, home appliance and other related fields have an increasingly obvious demand for high-quality cold-rolled high-strength steel. One of the methods to improve the strength of cold-rolled strip is to achieve rapid cooling of the strip in a continuous annealing furnace.

[0003] When the strip undergoes continuous cold rolling annealing, the surface of the strip will oxidize when it comes into contact with the air, and the cooling material will adhere to the surface of the strip. When the strip is curled, the surface debris will damage the surface of the strip and reduce the quality of the strip.

[0022] When the steel strip moves inside the annealing rack, after the air cooler is powered on, the bottom of the vertical pipe is connected to the inside of the round pipe through the connecting pipe, and the air cooler pushes the gas through the air holes to cool the surface of the steel strip.

After the steel strip encounters oxygen, impurities oxidized on the surface are curled by the extrusion of the extrusion rod, which is convenient for cleaning through a rubber plate. The threaded rod is threadedly connected to the inner wall of the threaded hole frame. The threaded rod is twisted to push the extrusion rod for adjustment. When the threaded rod moves, the sliding rod is driven by the elastic rod to slide on the inner wall of the sliding hole frame, which is convenient for adjusting the extrusion rod and increasing the clamping force of the extrusion rod on the surface of the steel strip.
