Advantages of vacuum carburizing

The American Ipsen company proposed vacuum carburizing in the 1950s. Vacuum low-pressure carburizing has incomparable advantages in terms of the structure and performance of the workpiece after carburizing, process flexibility, production cost and environmental protection. It does not need to use carrier gases such as CO and CO2, but achieves efficient carbon transfer through high carbon flow, so that the carbon concentration in the surface austenite of the workpiece is quickly saturated, effectively overcoming the shortcomings of ordinary gas carburizing, and has a uniform infiltration layer. It has the characteristics of good performance, excellent infiltration layer structure, small fluctuation of surface carbon concentration, high degree of automation, and low environmental pollution. Carburizing under vacuum conditions can effectively avoid the black structure and surface decarburization of the carburized layer due to intergranular oxidation .

Vacuum carburizing equipment

The outstanding features of vacuum carburizing equipment are the variety of options, multiple uses and advanced carburizing control systems. Users can make a variety of choices for low-pressure vacuum carburizing equipment according to different requirements, and choose single-chamber, double-chamber, three-chamber or multi-chamber furnaces according to the requirements of the number of processing chambers in the equipment configuration; according to the different loading methods of carburizing workpieces Vertical or horizontal furnaces can be selected; oil quenching or gas quenching furnaces can be selected according to different quenching methods; degassing chamber, preheating chamber, carburizing chamber, carbonitriding can be selected in the equipment according to different processing chamber functions chamber, slow cooling chamber or quenching chamber; furnaces with different effective heating zone sizes can be selected; the equipment can be installed in a special heat treatment workshop or a mixed workshop, forming a joint production line with cold processing equipment; It can be either periodic vacuum carburizing equipment or production line vacuum carburizing equipment. Vacuum carburizing equipment has a variety of uses, and can flexibly realize various heat treatment processes, such as vacuum carburizing, vacuum carbonitriding, vacuum carburizing + oil quenching, vacuum carburizing + gas quenching, and full functions of vacuum tempering furnaces .

The use of vacuum carburizing

At present, in the automobile industry of developed countries in the world, low-pressure vacuum carburizing heat treatment has been gradually applied, and it will gradually replace the conventional controlled atmosphere carburizing (or carbonitriding) heat treatment and become the main heat treatment production technology.
