Effect of Heat Treatment on the Quality of Deep Groove Ball Bearings
Deep groove ball bearings in the production process contains a variety of manufacturing processes, which have a strong technical manufacturing process is a deep groove ball bearing heat treatment. This is the deep groove ball bearings in the production of the most important one process, to a large extent affect the quality of deep groove ball bearings. However, many enterprises of the bearing procurement staff on the deep groove ball heat treatment process does not understand, resulting in the purchase of deep groove ball bearings can not judge its quality, the impact of follow-up use. Strong bearing has its own bearing technology R & D team, we summed up in recent years, deep groove ball heat treatment technology development of several types, according to different kinds of heat treatment, can greatly enhance the use of deep groove ball bearings performance, to ensure deep groove ball bearings The quality of production.
Clean heat treatment
We may not know, deep groove ball bearing heat treatment production will form waste water, waste gas, waste salt, dust, noise and electromagnetic radiation will cause pollution to the environment, and clean heat treatment technology can solve the problem of environmental pollution, but also Bearing heat treatment technology one of the direction of development. Clean heat treatment technology has basically put an end to the use of coal as fuel, greatly reducing the SO2, CO, CO2, dust and cinder emissions, to solve the deep groove ball bearing heat treatment caused by pollution problems.
Less heat-free heat treatment
Less heat-free heat treatment due to the precise control of carbon potential, nitrogen potential control of the atmosphere heating instead of the traditional oxidation atmosphere heating, can significantly improve the performance of deep groove ball bearings, decarburization and cracks and other bearing heat treatment defects have been resolved The Less heat-free heat treatment of the follow-up processing to reduce the amount, but also improve the utilization of materials and processing efficiency. Vacuum heating gas quenching, vacuum or low pressure carburizing, nitriding, nitrocarburizing and boronizing can significantly improve the quality, reduce
distortion and improve life.
Energy saving heat treatment
Deep groove ball bearings are often in the heat treatment of waste heat can not be fully caused by the waste of energy, and energy-saving heat treatment in the heat treatment of energy structure, by giving priority to primary energy, make full use of waste heat, waste heat, reduce the heat treatment process cycle Play all aspects of the ability to make energy to the most effective use.
Precision heat treatment
Under normal circumstances, we said that the precision heat treatment contains two meanings: First, according to the use of deep groove ball bearings needs, materials, structural size, the use of physical metallurgy knowledge and advanced computer simulation and detection technology to optimize the process parameters to achieve the required Performance or maximize the potential of the material; the other is to fully guarantee the stability of the heat treatment process to achieve a very small dispersion of product quality and heat treatment distortion is zero.
Not only deep groove ball bearings, all the heat quality of the bearings are in the machinery industry in the most stringent. Bearing heat treatment in the past 20 years has made great progress, but there are still many aspects of the improvement of the test of each bearing practitioners.
