Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein
Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.
Referring to shown in attached drawing 1-2, the embodiments of the present invention disclose a kind of annealing furnace hot air circulation cooling system, including
Cooling section 10 and degreasing section 3 are equipped with airflow channel 4, the airflow channel 4 one between the degreasing section 3 and the cooling section 10
End connects 3 inner cavity of degreasing section, and the other end connects 10 inner cavity of cooling section, and the degreasing section 3 is equipped with water-cooling apparatus
5, the cooling section 10 is equipped with air-cooling device 6, and the water-cooling apparatus 5 sprays cold on the steel band into the degreasing section 3
But water forms the vapor of heat, and the hot steam that the degreasing section 3 is formed enters the cooling section 10 from the airflow channel 4.Institute
It states cooling section 10 to be made of five groups of cooling units connected side by side 11, the cooling unit 11 is respectively provided with one group of corresponding air cooling
