introduction：Development history of heat treatment （1）Cleaning heat treatment Waste water from heat treatment production、Exhaust gas、Waste salt、dust、Noise and electromagnetic radiation will cause pollution to the environment。Solve the environmental pollution problem of heat treatment，Perform clean heat treatment（Or green heat treatment）It is one of the directions of the development of heat treatment technology in developed countries。To reduceSO2、CO、CO2、Dust and cinder discharge，The use of coal as fuel has been virtually eliminated，Less heavy oil is being used，Most have switched to light oil，Natural gas remains the most desirable fuel。 The waste heat utilization of combustion furnace has reached a high level

introduction：Heat treatment of die is an important process to ensure the performance of die。It has a direct impact on the following properties of the mold。 Mold manufacturing accuracy：The tissue transformation is not uniform、Incomplete and excessive residual stress caused by heat treatment cause mold processing after heat treatment、Deformation during assembly and mold use，Thus reducing the accuracy of the mold，Even scrap。 Strength of die：Heat treatment process is not properly formulated、The heat treatment operation is not standard or the heat treatment equipment is not in good condition，Causes the strength of the mold being treated(hardness)Not up to design requirements。 The working life of the mold：Structural disconformity caused by heat treatment

introduction：Some users have broken the output shaft of the drive motor after several months of operation of the equipment。Why did the reducer break the output shaft of the drive motor？For this purpose we looked at the output shaft cross section of the drive motor，It is found that the cross section of the output shaft of the reducer is almost exactly the same。The outer ring of the cross section is brighter，And the more toward the axis of the section color darker，It breaks at the end of the shaft！figure2Its a cross-sectional photo。This fully shows that the main reason for the broken shaft of the output shaft of the drive motor is that the motor and the reducer are assembled differently！ When the concentricity between the motor and the reducer is guaranteed to be very good，Motor output bearing[bearing:
