Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment furnace structures, in particular to a heat treatment furnace structure. Background Art

[0002] The furnace body of the heat treatment furnace is usually composed of steel plates, steel plate skeletons and insulation layers. The inner wall and door panel of the furnace are usually made of high-temperature wear-resistant materials to ensure its good high-temperature resistance and corrosion resistance. In addition, the furnace body must also have good sealing performance to ensure the heat treatment effect. The heating system is usually composed of a gas heater or a resistance heating system. The gas heater is a device that uses gas energy for heat treatment. It has the advantages of high efficiency, energy saving and environmental protection. It is suitable for heat treatment of high-temperature and high-strength alloys. The resistance heater uses the thermal energy resistance effect to convert electrical energy into thermal energy and is suitable for low-temperature heat treatment.

[0003] Although the current heat treatment furnace structure can perform heat treatment on metals, the existing heat treatment furnace structure mainly adopts natural exhaust for the heat treatment of high-temperature and high-strength alloys. It is easy for the chimney to be not cleaned for a long time, and the accumulated ash and carbon deposits will reduce the chimney's ability to pass air. When the chimney suction is insufficient, the furnace gas rises, the temperature in the upper part of the furnace is high, and sometimes the temperature difference between the upper and lower parts reaches 200°C, so that some metals cannot fully react during the heating process. At the same time, when the existing heat treatment furnace needs to take out the metal during use, since the heat treatment furnace has only one opening for taking out, the staff needs to move the metal so that the metal can enter the next step, which increases the workload of the staff. At the same time, when the staff moves the metal, the overheated metal will cause harm to the staff. Utility Model Content
