Hot galvanizing noise reduction and edge thickness control baffle, device and method

Abstract

The invention discloses a hot galvanizing noise reduction and edge thickness control baffle, device and method, and relates to the field of noise reduction baffles. The hot galvanizing noise reductionand edge thickness control baffle comprises a baffle, a mounting block on the upper portion of the baffle and a noise reduction plate, wherein the hot galvanizing noise reduction and edge thickness control baffle is divided into a working area, a transition area and a noise reduction area, the lower end of one side, far away from the transition area, of the working area is arc-shaped, the transition area and the noise reduction area are provided with airflow guide grooves, and the noise reduction area is also provided with the noise reduction plate. The hot galvanizing noise reduction and edge thickness control device comprises the hot galvanizing noise reduction and edge thickness control baffle, strip steel and an air knife plate, when the strip steel is treated by the hot galvanizing noise reduction and edge thickness control device, the noise pollution is reduced due to the special structure of the baffle and the matched use method of the device, and the edge thickness control ofthe treated strip steel is better.

Description

technical field [0001] The invention relates to the field of noise-reducing baffles, in particular to a baffle, device and method for hot-dip galvanizing noise reduction and edge thickness control.

Problems solved by technology

[0002] With the environmental protection requirements of industrial production on the site environment are getting higher and higher, the control of noise is gradually being paid attention to, and the continuous hot-dip galvanizing unit is continuously increasing with the speed of the production line. The air knife currently used is widely used as air knife or nitrogen The main medium, in order to accurately control the weight of the coating required by customers, the excess liquid zinc is blown through a certain pressure of airflow to obtain the target control coating weight, the air knife uses gas as the main medium, and the existing air knife Under certain conditions, using the smallest control gap and adjusting the lip gap of the air knife to the best, still cannot effectively reduce the noise generated by the air knife blowing the zinc liquid, which has a greater impact on the working environment

[0003] During the working process of the air knife, the noise generated has always been one of the important topics studied by manufacturers and research institutes, optimizing the structure of the air knife, reducing the working time of personnel in high-noise environments, etc. However, the reduction of noise still has certain limitations. The noise generated on site still requires the staff to wear anti-noise earplugs, anti-noise helmets, earmuffs, etc. to isolate or reduce the noise
