The utility model content
There are problems such as speed of cooling is slow, band steel cooling uniformity is bad in the utility model in order to solve existing cool wind box, and then a kind of zinc-plated annealing furnace multilayer airduct circulation jet flow cool wind box is provided.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: cool wind box described in the utility model comprises the bellows seat, insulation pot, a plurality of airducts, airduct union lever and erecting frame, uniformly on the sidewall of each airduct have a plurality of spouts, a plurality of airducts are horizontally disposed with the formation tube bank and a plurality of airduct is rectangular distribution, the end of a plurality of airducts is installed on the bellows seat, insulation pot is installed on the bellows seat and insulation pot covers in the tube bank that is made of a plurality of airducts, from top to bottom a plurality of airducts of She Zhiing are row, leave between every adjacent two row airducts and be used to the gap passed with steel, each row airduct is provided with erecting frame by linking together by an airduct union lever between the adjacent two row airducts.
The beneficial effects of the utility model are:
The utility model comes design cycle jet flow cool wind box by the airduct that adopts multilayer to have spout, can make the cool wind box speed of cooling accelerate, be with the steel cooling evenly, is applicable to the process for cooling of band steel on the galvanization production line fully.Concrete advantage of the present utility model is:
1, the utility model is compared with existing bellows and has been adopted layered arrangement, by use of the present utility model, makes band steel plate temperature better controlled in processing parameter;
2, these bellows adopt circular duct, and compare protection gas suffered flow resistance in bellows with square bellows littler; And it is more stable that the angled ejection of air-flow makes the protection air-flow in protection gas and the bellows, reduces the shake of band steel in the stove, thereby can reduce the too high tensile influence of band steel;
3, this cooling structure makes the circulation of protection gas obtain good control, helps save energy;
4, this cooling structure is made simply, reduces cost of manufacture.
