Bearing steel tube heat treatment process formula!


Precision heat treatment

Precision heat treatment has two meanings: on the one hand, according to the use of parts requirements, materials, structure size, the use of physical metallurgy knowledge and advanced computer simulation and testing technology, optimize the process parameters, to achieve the required performance or maximize the potential of the material; On the other hand, the stability of the optimized process is fully guaranteed, and the product quality dispersion degree is very small (or zero) and the heat treatment distortion is zero.

Energy saving heat treatment

Scientific production and energy management are the most potential factors for the effective use of energy. The establishment of professional thermal treatment plants to ensure full load production and give full play to equipment capacity is the choice of scientific management. In terms of heat treatment energy structure, primary energy is preferred. Make full use of waste heat and waste heat; Adopt the process with low energy consumption and short cycle to replace the process with long cycle and high energy consumption.

Less oxidation free heat treatment

By using protective atmosphere heating instead of oxidation atmosphere heating to control carbon potential and nitrogen potential controllable atmosphere heating, the performance of the parts after heat treatment is improved, the defects of heat treatment such as decarburization, cracks, etc. are greatly reduced, the amount of finishing left after heat treatment is reduced, and the material utilization rate and machining efficiency are improved. The quality, distortion and service life can be improved obviously by vacuum and hot gas quenching, vacuum or low pressure carburizing, nitriding, nitrocarburizing and boronizing.

Bearing parts heat treatment quality control in the whole machinery industry is the most stringent. Bearing heat treatment has made great progress in the past 20 years.
