Vacuum heat treatment is a new treatment technology combining vacuum technology and heat treatment technology, which can realize almost all the heat treatment processes involved in conventional heat treatment, and greatly improve the quality of heat treatment and the oxidation resistance and corrosion resistance of the workpiece. It can achieve no oxidation, no decarburization, no carburization, remove the phosphorus chips on the surface of the workpiece, and have the effect of degreasing and degassing, so as to achieve the effect of bright and purified surface.
Vacuum carburizing is also a kind of carburizing, but the performance of the equipment is different, of course, the process is also very different. Vacuum carburizing is divided into vacuum carburizing oil quenching furnace and vacuum carburizing gas quenching furnace according to different quenching methods. From the appearance of the vacuum carburizing oil quenching furnace and vacuum oil quenching furnace similar, vacuum carburizing gas quenching furnace and vacuum high-pressure gas quenching furnace similar. After the addition of carburizing function, more gas supply system, gas flow control system, carburizing pressure control system and changes to the heating system, these system additions and changes, most of them are inside the equipment, so the appearance of the vacuum carburizing furnace and vacuum furnace is not very different.
The 19th Beijing International Heat Treatment Exhibition 2019 was held on August 9-11, 2019 in Hall 6-7 of China International Exhibition Center (Jing'anzhuang) in Beijing. The exhibition is unprecedented, exhibitors reached more than 130, held 14 technical office sessions, attracting a total of more than 6,000 professional visitors to visit.
The annual "Autumn Staff Training" of Zhengzhou Feixhong Heat Treatment Equipment Manufacturing Co. In order to detect the effect of this skills training, consolidate the staff skills knowledge mastery, in the company's leadership attaches great importance to the strict organization of the training teachers, the training summary of this year's examination.
This equipment is mainly used for plate heat exchanger parts, which realizes continuous intelligent operation, automatic transfer between stations, automatic pressing during heating, continuous pressure control, compact structure, high vacuum degree (ultimate vacuum degree: 6.7╳10-4Pa, test vacuum degree reaches The machine has compact structure, high vacuum degree (ultimate vacuum degree: 6.7╳10-4Pa, test vacuum degree: 5.8╳10-5Pa), fast and efficient production cycle, saving manpower and material resources.
Carburizing is the process of making carbon atoms infiltrate into the surface layer of steel. It is also the process of making a low carbon steel workpiece with the surface layer of high carbon steel, and then quenching and low temperature tempering to make the surface layer of the workpiece with high hardness and wear resistance, while the central part of the workpiece still maintains the toughness and plasticity of low carbon steel.
