Bearing heat treatment technology, which has several

     (1) Clean the heat treatment heat treatment of wastewater, waste gas, waste salt, dust, noise and electromagnetic radiation etc. formed on the environment caused by pollution. Heat treatment to solve environmental problems, implement clean heat treatment (also known as green heat treatment) is one of the directions developed heat treatment technology development. In order to reduce SO2, CO, CO2, and cinder dust emissions, has been basically put an end to the use of coal as a fuel, the amount of heavy oil is less and less in favor of mostly light oil, natural gas is still the best fuel. Furnace waste heat utilization has reached a high degree of optimization and configuration of the burner air - fuel ratio to ensure strict control of the combustion reasonable premise that NOX and CO reduced to a minimum; use of gas carburizing, carbonitriding and vacuum heat treatment technology alternatives to reduce the salt treatment and waste salt containing CN- toxic pollution of water; a water-soluble synthetic oil instead of part of the quenching oil quenching, using biodegradable vegetable oil instead of mineral oil to reduce the portion of oil contamination.

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

     (3) energy-saving heat treatment of scientific production management and energy efficient use of energy is the most promising factors, a professional heat treatment plant in order to ensure full capacity, full capacity of equipment is scientific management choice. In the heat treatment of the energy structure, preference primary energy; full use of waste heat, waste heat; use low-energy, short cycle process instead of long period, large energy-consuming processes.

     (4) less non-oxidation heat treatment by the use of protective atmosphere heating alternative oxidizing atmosphere heated to a precise control of carbon potential, nitrogen potential of controlled atmosphere heat after heat treatment improved the performance of the parts, heat treatment significantly reduced defects such as decarbonization, cracks, heat treatment after finishing allowance reduction, improving the utilization efficiency of the material and machining. Vacuum heating gas quenching, vacuum or low pressure carburizing, nitriding, nitrocarburizing and boriding, etc. can significantly improve quality, reduce distortion and improve life.

     Bearing parts heat treatment quality control in the whole machinery industry is the most critical. Bearing heat treatment in the past 20 or so years has made great progress, mainly in the following areas: Heat Treatment basic theory; heat treatment process research and application of technology; the development of new heat treatment equipment and related technologies.
