Abstract

The invention relates to a novel blowing device of a cold rolling device, which comprises a large flow centrifugal blower, an upper blowing air blade and a lower blowing air blade, wherein the large flow centrifugal blower is connected with a main pipe, the main pipe is internally provided with a control valve and communicated with the upper blowing air blade through an upper pipe and the lower blowing air blade through a lower pipe, the upper blowing air blade and the lower blowing air blade are fixedly arranged on a base of the cold rolling device, a blowing station used for placing a cold roll steel sheet is arranged between the upper blowing air blade and the lower blowing air blade; an included angle between the plane of an air outlet of the upper blowing air blade and the longitudinal center plane of the upper blowing air blade is 30-60 degrees, and an included angle between an air outlet of the lower blowing air blade and the longitudinal center plane of the lower blowing air blade is 30-60 degrees. The novel blowing device has weak noise, reduces the energy consumption and the cost and is convenient for maintenance.

Description

technical field [0001] The invention relates to a cold rolling equipment of a metallurgical system, in particular to a purging device. Background technique [0002] All cold rolling blowing systems are designed to use traditional air pressure blowing. The advantages of this blowing system are: large blowing force, easy to dry the plate surface. When using compressed air to blow: When the compressed air passes through the small hole on the purge head, it can be regarded as the flow rate of the gas passing through the shrinking nozzle or small hole. Here, the volume flow is used for calculation. According to the mechanical design manual, it can be found that: when P / P 0 When >0.528, the volume flow rate under the standard state is: When P / P 0 When ≤0.528, the volume flow rate under the standard state is: Q V = 454 S P 0 293 ...
