Reasons for high temperature of fag bearing in Germany

Reasons For High Temperature Of Fag Bearing In Germany

(1) Clean heat treatment waste water, waste gas, waste salt, dust, noise and electromagnetic radiation from heat treatment production will pollute the environment. To solve the environmental pollution problem of heat treatment and implement clean heat treatment (or green heat treatment) is one of the development directions of heat treatment technology in developed countries.

In order to reduce the emission of SO2, Co, CO2, dust and cinder, the use of coal as fuel has been basically Dimension Series eliminated, and the use of heavy oil is becoming less and less. Most of them use light oil, and natural gas is still an ideal fuel. The waste heat utilization of combustion furnace has reached a high degree.

The optimization of burner structure and the strict control of air-fuel ratio ensure the reasonable combustion, so as to reduce NOx and CO to a low limit; Using gas carburizing, carbonitriding and vacuum heat treatment technology instead of salt bath treatment to reduce the pollution of waste salt and CN toxic substances to water sources;

Water soluble synthetic quenching oil is used to replace some quenching oil, and biodegradable vegetable oil is Dimension Series used to replace some mineral oil to reduce oil pollution.

(2) Precision heat treatment precision heat treatment has two meanings:

on the one hand, according to the use requirements, materials and structural dimensions of parts, it uses physical metallurgy knowledge and advanced computer simulation and detection technology to optimize process Dimension Series parameters to achieve the required performance or give full play to the potential of materials;

On the other hand, the stability of the optimized process is fully guaranteed, and the product quality dispersion is Dimension Series very small (or zero) and the heat treatment distortion is zero.

(3) Scientific production and energy management of energy-saving heat treatment are potential factors for effective utilization of energy. Dimension Series Establishing a professional heat treatment plant to ensure full load production and give full play to equipment capacity is the choice of scientific management.

In terms of energy structure of heat treatment, primary energy is preferred; Make full use of waste heat and Dimension Series waste heat; Adopt the process with low energy consumption and short cycle to replace the process with long cycle and high energy consumption.

(4) Less and no oxidation heat treatment is from using protective atmosphere heating instead of oxidation atmosphere heating to controllable atmosphere heating with accurate control of carbon potential and nitrogen potential.

After heat treatment, the performance of parts is improved, heat treatment defects such as decarburization and cracks are greatly reduced, finishing allowance after heat treatment is reduced, and material utilization and machining efficiency are improved.

Vacuum heating and gas quenching, vacuum or low pressure carburizing, nitriding, nitrocarburizing and boronizing can significantly improve quality, reduce distortion and improve service life. The heat treatment quality control of fag bearing parts is strict in the whole machinery industry.
