In May 2018, 5.5 m gas furnace with side door is installed and debugged smoothly, this furnace belongs to batch furnace, which is mainly used for heating metal artifacts, for annealing heat treatment.
The design of slide furnace door is designed to consider the restriction of the height on the crane at the customer factory and the height of the factory, and the slide door can effectively reduce the height restriction.
This type of batch furnace mainly composed of furnace body, furnace lining, furnace door and the furnace door opening device, sealing device, trolley, combustion system, gas pipeline, air pipeline, exhaust pipeline, sealing device and electrical and automation system and components.
