Description

Technical Field

[0001] The utility model relates to the technical field of annealing furnaces, in particular to an annealing furnace which is convenient to maintain. Background Art

[0002] Annealing furnace is a kind of equipment that applies slow heating and cooling process below critical temperature to metal, the purpose is to eliminate the structural stress inside the metal caused by cold working and improve the plasticity of the metal. Annealing furnace can be divided into electric annealing furnace and gas annealing furnace according to the type of heat source. Among them, electric annealing furnace is divided into alkaline annealing furnace and acid annealing furnace according to the atmosphere in the furnace. Gas annealing furnace mainly uses natural gas as fuel and is widely used for bright annealing, isothermal annealing, stress relief annealing, etc. Most of the existing annealing furnaces fix the thermal insulation lining to the inner wall of the furnace body by anchoring or threading. Under the condition that the thermal insulation lining is deformed or damaged, the staff needs to enter the furnace body to maintain or replace the thermal insulation lining. The above-mentioned anchoring or threading method makes the staff time-consuming and labor-intensive to operate, and needs to be improved. Utility Model Content
