Abstract

The invention discloses an annealing furnace. The furnace comprises a furnace body. An annealing shell body is arranged in the furnace body. Gaps are arranged between the furnace body and the bottom surface of the annealing shell body as well as between the circumference surface of the annealing shell body. The upper end of the annealing shell body is fixedly connected with the furnace body. The circumference surface on the middle-upper portion of the annealing shell body is besprinkled with through holes. The inner lower portion of the annealing shell body is provided with a support plate. A thermal insulation layer is arranged on the support plate. The thermal insulation layer is provided with a fixed pillar and a plurality of fixed grooves. A fixed plate is detachably arranged at the top end of the fixed pillar. A plurality of grooves are formed in the positions, corresponding to the fixed grooves, of the fixed plate and are matched with gas cylinder openings. A furnace lid is arranged at the top end of the furnace body and provided with a gas purification cavity. An air cylinder is arranged at the lower end of the furnace body. An air cylinder output shaft extends into the furnace body and is connected with the support plate. An air heater is arranged at the lower end of the furnace body and communicated with the gap between the bottom surface of the annealing shell body and the furnace body. The annealing furnace is capable of improving the working efficiency.

Description

technical field [0001] The invention relates to the technical field of metal annealing, in particular to an annealing furnace. Background technique [0002] Annealing refers to slowly heating a metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. The purpose is to reduce hardness, improve machinability; eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grain, adjust structure, and eliminate structure defects. The annealing of gas cylinders is to eliminate internal stress and achieve good plasticity. The annealing furnace is a machine used to implement the annealing process. [0003] The existing gas cylinders are annealed in the annealing furnace, and the surface of the gas cylinder cannot be heated uniformly, resulting in poor annealing effect; in addition, it is very inconvenient to take out the gas cylinder after the annealing is completed. Contents of the invention [000...
