When YRT turntable bearings are heat-treated, it is directly related to the subsequent processing quality and affects the performance and life of the parts. And bearing heat treatment is also the place of energy consumption and pollution in bearing manufacturing. The bearing heat treatment equipment directly affects the bearing heat treatment quality, as well as energy consumption and pollution. So when using it, pay attention to the following points.
(1) Clean heat treatment
Waste water, waste gas, waste salt, waste oil and electromagnetic radiation from heat treatment production will pollute YRT turntable bearings. To solve the environmental pollution problem of heat treatment, the implementation of clean heat treatment (or green heat treatment) is one of the development directions of heat treatment technology. This places high demands on the heat treatment atmosphere, quenching oil and cleaning equipment.
(2) Precision heat treatment
Precision heat treatment is to fully ensure the stability of the optimized process, achieve very small (or zero) product quality dispersion, zero heat treatment distortion, reduce grinding allowance, improve production efficiency, and save materials. The realization of precision heat treatment must have good furnace temperature uniformity, temperature control accuracy, and good cooling and stability of the quenching agent.
(3) Energy-saving heat treatment
When using YRT turntable bearings, it is necessary to select new thermal insulation materials to improve the energy utilization rate of heat treatment equipment; optimize the heat treatment process, increase process output, and give full play to the capabilities of the equipment.
(4) The manufacturer of crossed tapered roller bearing with less non-oxidizing heat treatment stated that by using protective atmosphere heating instead of oxidizing atmosphere heating to a controlled atmosphere heating with precise control of carbon potential and nitrogen potential, the performance of parts after heat treatment is improved, and heat treatment defects such as oxidation, Decarburization and cracks are greatly reduced, the finishing allowance after heat treatment is reduced, and the material utilization rate and machining efficiency are improved.
