Abstract
Description
Technical Field
[0001] This utility model relates to the field of strip steel production technology, specifically to a drying device for continuous annealing production. Background Technology
[0002] The purpose of annealing cold-rolled strip steel is to reduce severe work hardening and improve the formability of the sheet. Annealing is typically performed above the recrystallization temperature to obtain a soft microstructure with good cold formability. During annealing, there is a possibility of linking recrystallization with changes in the steel's chemical composition, which involves reaction annealing. If high strength is desired for the sheet's processing and use, and there are no special requirements for cold formability, annealing can also yield a microstructure between fully roll-hardened and fully recrystallized microstructures. In this case, heat treatment is used for recovery and partial recrystallization.
[0003] The continuous annealing process requires pickling → cold rolling → uncoiler → inlet shearing → welding → cleaning → drying → inlet looper → continuous annealing. Therefore, cleaning is required before annealing, followed by drying. However, existing drying equipment mostly uses high temperature drying, which takes a long time, has low drying efficiency, and high energy consumption, resulting in high production costs.

A first fixing rod and a second fixing rod are mounted on both sides of the steel belt. A first fixing block and a second fixing block are respectively fixed on the first fixing rod and the second fixing rod. A rubber scraper is clamped and fixed on the first fixing block. An air-cutting nozzle is fixed on the second fixing block. An outer shell is provided between the first fixing block and the second fixing block. A negative pressure chamber is opened inside the outer shell. A brush roller is rotatably installed in the negative pressure chamber of the outer shell. A negative pressure pipe is connected to the outer shell.
[0007] The beneficial effects of this utility model are as follows: When in use, after the strip steel is cleaned, excess water is scraped off by a rubber scraper, and then the excess water on the strip steel is further brushed off by a rotating brush roller. The rotation direction of the brush roller is opposite to the conveying direction of the strip steel. The water brushed off is extracted through a negative pressure pipe, and then the strip steel is dried by air cutting nozzles again, thereby completely removing the water on the cleaned strip steel.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, the negative pressure chamber is connected to the negative pressure pump via a negative pressure pipe.
[0010] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the extraction of water accumulated in the negative pressure chamber and increases the water removal efficiency.
[0011] Furthermore, both ends of the brush roller are connected to an external power device via a synchronous belt or gear.
