Description
Technical Field
[0001] The utility model relates to the technical field of nitriding treatment, in particular to a high-temperature nitriding treatment tank. Background Art
[0002] Gas nitriding furnace is also called nitriding furnace. Gas nitriding is a heat treatment process. Nitriding treatment refers to a chemical heat treatment process that allows nitrogen atoms to penetrate into the surface of the workpiece at a certain temperature and in a certain medium. The role of nitriding is: 1. Nitriding can make the surface of the parts have higher hardness and wear resistance. 2. Fatigue resistance. Due to the greater pressure formed in the nitriding layer, the fatigue limit of the nitrided workpiece can be increased by 15% to 30%. 3. Improve the corrosion resistance of the workpiece. Nitriding can form a dense phase layer with high chemical stability on the workpiece, which has high corrosion resistance in water vapor and alkaline solution. Nitriding process: Ammonia is introduced into the stainless steel vacuum sealed tank in the nitriding furnace and heated to 490℃~550℃. Keep it for a proper time. According to the material and deep requirements of the workpiece, the insulation time ranges from 3 to 90 hours. The desalination treatment equipment is mainly used for traditional Christmas or nitrocarburizing of gear shafts, crankshaft molds and other workpieces. It has the characteristics of low treatment temperature, short time and small deformation of the workpiece.
[0003] At present, nitriding treatment mainly includes four types: vacuum nitriding, gas nitriding, solid nitriding and liquid nitriding. Vacuum nitriding is to treat the material with nitrogen under vacuum conditions, which can achieve controllable penetration of nitrogen atoms, thereby forming a hard nitride layer on the surface of the material. Gas nitriding is to place the workpiece in an environment containing a nitriding agent (such as ammonia) and control the temperature and time to allow nitrogen atoms to penetrate the surface of the material. Solid nitriding is to contact the workpiece with active nitride powder at a certain temperature to allow nitrogen atoms to penetrate the surface of the material. Liquid nitriding is to immerse the workpiece in liquid nitrogen or other cooling media and quickly cool it to obtain a surface hardening effect.
[0004] At present, the industry uses gas nitriding to perform batch processing on workpieces. The number of workpieces to be processed in batches is large and the volume is heavy. The existing technology mainly places several workpieces to be processed in batches on a hanger or a trolley with a hanger, and then uses a manipulator or a forklift to take the workpieces in the nitriding treatment tank. Such an operation is easy to cause serious wear of the power transmission components of the manipulator or forklift due to the large number of workpieces and the heavy volume, and the great force applied when the manipulator or forklift takes the workpieces. Therefore, it is necessary to provide a high-temperature nitriding treatment tank. Utility Model Content
