Description

Technical Field

[0001] The utility model relates to the technical field of bell-type annealing furnaces, in particular to an automatic cleaning bell-type annealing furnace for steel coil production. Background Art

[0002] The bell-type annealing furnace is a metal strip annealing device, which is used in an environment that requires annealing in a low-oxygen atmosphere. The equipment is mainly composed of a furnace table, a material tray, a circulating fan, an inner cover, a heating cover, a cooling cover and other components. During the use of the bell-type annealing furnace, each device will be continuously contaminated. The bell-type furnace needs to be cleaned regularly, otherwise it will cause contamination to the annealing materials, especially to the annealing of the finished product;

[0003] The traditional cleaning method of a hood annealing furnace is to clean the inner wall by rotating a brush. Although this method can remove some impurities, the lack of prior wetting and softening steps results in limited cleaning effects, especially for stubborn stains adhering to the wall. It is difficult to achieve an ideal cleaning effect. Therefore, we propose an automatic cleaning hood annealing furnace for steel coil production to solve the above problems. Utility Model Content

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides an automatic cleaning bell-type annealing furnace for steel coil production, which has the following beneficial effects:
