The invention discloses a gas carbonitriding automatic control method and device. The device comprises nine devices, namely, a nitriding furnace 1, a PLC, a pressure sensor, a hydrogen probe, a thermocouple, a blade, a fan, a heating and temperature control device and an air exhausting device. After being subjected to degreasing, cleaning and surface treatment, a part is subjected to closed loop feedback control of a vacuum pump, nitrogen, ammonia, ethyl alcohol, temperature and pressure in the furnace, so that the nitrocarburizing of various common nitriding steel such as high-speed steel and stainless steel is achieved. The device is energy-saving and efficient in use, easy to maintain and free of pollution, the product is high in quality performance, the PLC control system is adopted to quickly confirm and control the depth of the white etching layer and the reticular layer of the part to be stable according to the number of corresponding parts and the technological parameters of the material, the uniformity of stainless steel mass production is stable, the ammonia consumption is less, the energy consumption is low, the nitridation time is short, and the efficiency is high.
Description
Technical field [0001] The automatic control method and device for gas carbonitriding of the present invention belong to the technical field of gas carbonitriding. Background technique [0002] Nitrocarburizing is a chemical heat treatment process that involves nitriding and carbon infiltration, also known as soft nitriding. The main purpose is to improve the wear resistance and seizure resistance of steel to meet product quality requirements. In the soft nitriding industry, companies continue to pursue better production processes, higher quality nitriding products, and more complete production control methods and devices with a more complete degree of automation to reduce labor costs, reduce human errors, increase process stability, and increase products. Quality and improve production efficiency, etc. [0003] The existing nitrocarburizing technology is mainly divided into liquid method and gas method, namely salt bath nitrocarburizing and gas nitrocarburizing. Because the salt ...
