Description

Technical Field

[0001] The utility model relates to the technical field of annealing furnaces, in particular to an annealing furnace with circulating cooling water. Background Art

[0002] Annealing is a metal heat treatment process, which means slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce hardness, improve machinability; reduce residual stress, stabilize size, reduce deformation and crack tendency; refine grains, adjust structure, and eliminate tissue defects. To be precise, annealing is a heat treatment process for materials, including metal materials and non-metallic materials. Annealing furnace is a kind of equipment used in annealing process. It is divided into three types according to its size: small, medium and large. Small and medium annealing furnaces are generally box annealing furnaces. When using this annealing furnace, the workpiece needs to be placed inside the equipment, and then the temperature of the workpiece is raised and maintained for a period of time by heating. After the heating process is completed, the hot air will be discharged, and cold air will be gradually introduced to cool the workpiece.

[0003] The existing annealing furnace equipment cooling method uses natural cooling or gradually introducing cold air to cool the heated workpiece, which takes a long time to cool, and the equipment lacks the function of recycling internal resources, which reduces resource utilization and reduces the environmental protection of the equipment.

[0004] Secondly, the mobility and controllability of existing annealing furnace equipment is not safe and convenient enough, resulting in poor stability of the equipment during operation and insufficient safety of use, which urgently needs to be developed. Utility Model Content
