Description

technical field [0001] The invention relates to the field of forging equipment, in particular to an annealing furnace for annealing by utilizing the waste heat of castings. Background technique [0002] In the production process of forgings, the process of annealing forgings is often involved. At present, the forging is generally cooled to room temperature, and then put into an annealing furnace for heating and annealing. However, this results in a loss of thermal energy for the forging, and the annealing furnace consumes a large amount of energy. Contents of the invention [0003] On the one hand, it provides an annealing furnace for annealing by using the waste heat of the casting, and the annealing is carried out by using the waste heat of the casting. [0004] In order to achieve the above purpose, the following technical solutions are specially adopted: [0005] An annealing furnace for annealing with the waste heat of castings, comprising: a furnace cover, a hollo...
