Description

Technical Field

[0001] The utility model relates to the technical field of cold-rolled strip steel processing, in particular to an automatic annealing device for cold-rolled strip steel. Background Art

[0002] The purpose is to eliminate the hardening of cold rolling, so that the steel plate can be recrystallized and softened, and have good plasticity. Annealing methods include bell-type furnace coil annealing and continuous furnace annealing. Coil annealing is divided into tight coil annealing and loose coil annealing. Continuous furnace annealing is divided into vertical continuous furnace annealing and horizontal continuous furnace annealing. Protective gas is generally introduced into the furnace. At present, bell-type furnace annealing is mostly used. Although the processing cycle is long, due to the large number of furnaces, flexible use, and investment savings, continuous furnace annealing has a large output. Among them, horizontal continuous furnace annealing is only used for processing and low-output special steel, such as decarburization annealing of silicon steel.

[0003] Prior art, such as: CN215251012U, an annealing device for cold-rolled strip steel. The utility model can flatten the cold-rolled strip steel with bad plate shape by setting a clamping roller to prevent uneven thickness. By setting a blower and a fan in coordination, the blower can perform preliminary annealing on the cold-rolled strip steel that has not entered the box body. After the clamping roller flattens the cold-rolled strip steel, the fan in the box body performs secondary annealing on the cold-rolled strip steel, and the annealing is uniform. By setting a protective gas tank and a gas delivery port in coordination, the protective gas in the box body can be evenly blown away to prevent thermal blockage caused by poor airflow circulation of the protective gas, which causes the steel plates to stick.

[0004] However, the device still has certain shortcomings during use. After flattening the cold-rolled steel, the cold-rolled steel strip cannot be flattened and placed according to the size of the plate. It has certain limitations to use only the limiting rollers. When the device is cooling, debris is easily generated on the outer surface of the cold-rolled steel strip, and the device cannot clean the debris from the outer surface of the cold-rolled steel strip, which will affect the overall quality of the cold-rolled steel strip and reduce its practicality.
