Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment equipment, and more specifically, to a gradual temperature heat treatment furnace. Background Art

[0002] Heat treatment furnace is a general term for industrial furnaces that perform various metal heat treatments on metal workpieces. The temperature is generally lower than that of a heating furnace. Heat treatment furnaces can adopt various types of heating furnaces. After the heat treatment furnace heats the workpiece to increase the temperature of the workpiece, the workpiece needs to be taken out of the furnace chamber of the heat treatment furnace and quickly placed in a water pool for quenching. The furnace door is opened by a cylinder, and then the workpiece is taken out. During this process, the workpiece is exposed to the air for a long time, resulting in unstable quality of the workpiece. The workpiece itself is also prone to cooling from the outside to the inside to form a temperature difference, which makes it difficult to ensure the intrinsic quality of the workpiece after quenching.

By controlling the rotation of the furnace body, the time the workpiece is exposed to the air can be greatly shortened, and the purpose of temperature control of the workpiece is achieved to ensure the quality of the workpiece. During the rotation and unloading process of the furnace body, the purpose of limiting the rotation angle of the furnace body is achieved through the interference between the limit block and the limit plate, thereby avoiding excessive flipping of the furnace body, ensuring the quenching quality, and ensuring the intrinsic quality of the workpiece after quenching and the consistency of the workpiece quality.

[0004] However, in actual use, this structure places the workpiece inside the furnace cavity and then heats it through the temperature inside the furnace body, resulting in a higher temperature on the side close to the air outlet and a lower temperature on the side far from the air outlet, which causes uneven heating of the workpiece during the heating process, thus affecting the quality of the workpiece.
