Natural gas is still the most ideal fuel
2020年11月10日Precision heat treatment Precision heat treatment has two meanings: on the one hand, it is based on the use requirements, materials, and structural dimensions of the parts, using physical metallurgy knowledge and advanced computer simulation and testing techniques to optimize process parameters to achieve the required performance or Maximize the potential of the material; on the other hand, fully guarantee the stability of the optimized process, and achieve a small (or zero) product quality dispersion and zero heat treatment distortion.
The quality of heat treatment is directly related to the quality of subsequent processing and ultimately affects the performance and life of parts. The heat treatment quality control of bearing parts is the most stringent in the entire machinery industry. Vacuum heating gas quenching, vacuum or low-pressure carburizing, nitriding, nitrocarburizing and boronizing can significantly improve quality, reduce distortion and increase life. Most people switch to light oil, and natural gas is still the most ideal fuel.
The waste heat utilization of the combustion furnace has reached a high level. Bearing heat treatment has made great progress in the past 20 years, mainly in the following aspects: research on basic heat treatment theory; research on heat treatment technology and application technology; development of new heat treatment equipment and related technologies. In order to reduce the emissions of SO2, CO, CO2, dust and coal slag, the use of coal as fuel has been basically eliminated, and the use of heavy oil is becoming less and less.
Less non-oxidizing heat treatment uses protective atmosphere heating instead of oxidizing atmosphere heating to controllable atmosphere heating with precise control of carbon potential and nitrogen potential. After heat treatment, the performance of parts is improved, and heat treatment defects such as decarburization and cracks are greatly reduced
