Background

Brass is an alloy composed of copper and zinc, and brass composed of copper and zinc is called general brass, and if it is a plurality of alloys composed of two or more elements, it is called special brass. The brass has stronger wear resistance, and is often used for manufacturing valves, water pipes, connecting pipes of internal and external machines of air conditioners, radiators and the like. The brass band is one of brass products, and has large market demand and wide application due to good mechanical property.

In the production process of the brass band, a bell jar furnace is needed to carry out heat treatment on the brass band. When the existing bell jar furnace is used, the air in the bell jar furnace does not flow, so that certain unevenness exists in the temperature distribution in the bell jar furnace, the heat treatment of the brass strip is not facilitated, meanwhile, the position of the brass strip in the bell jar furnace cannot be moved, the phenomenon of unevenness is easy to occur when the brass strip is heated in the heat treatment, and the actual production of the brass strip is further influenced.

In view of this, we propose a bell jar furnace for producing brass strip.
