A large domestic steel plant, cold rolled plate continuous production line, production of cold rolled plate. The original air knife drying system uses high-pressure fan to remove oil, using 4 12.5KW high-pressure fans, a total of 50KW, equipped with 4 pieces of 1700mm in length, and the effect is not good, energy consumption is large, which has a serious impact on the product quality of cold-rolled plate.According to the requirements of the steel plant, Airhank company provided professional solutions after on-site investigation and understanding. Equipped with 1700 mm2 hank SA series stainless steel pressure equalizing blades, hank-100 & nbsp; 15HP high speed centrifugal blower were used to replace them. The original production speed was increased from 220m / min to 300m / min, and the production capacity was increased by 36.3%.It not only solves the problem of poor drying effect, but also ensures the quality of cold rolled sheet. It also reduces energy consumption and improves production efficiency. Hank engineer also put forward the scheme of using one for use and one for standby according to the situation, so as to avoid the huge loss caused by the fan damage in the original system.
