Description

Technical Field

[0001] The present application relates to the technical field of strip steel drying, and in particular to a cold-rolled silicon steel drying device. Background Art

[0002] After the strip is cleaned in the cleaning section, a certain amount of moisture will remain on the surface. If this moisture is not removed in time, it may affect the subsequent processing of the strip, such as cold rolling, welding, etc., and even cause rust, defects and other problems in the product. Therefore, the strip needs to be dried to remove the moisture on the strip surface and improve product quality.

[0003] Traditional cold-rolled silicon steel drying equipment uses hot air drying, which requires a special high-temperature resistant fan to introduce 200°C hot air from the furnace area heat exchanger. The pipeline distance is as long as 100 meters, which consumes a lot of heat energy and increases production costs. In addition, the nozzle is a hole nozzle, and the blowing effect is poor, which affects the quality of the strip steel product. Utility Model Content
