The hottest share of steel heat treatment technolo

  • Detail

The purpose of heat treatment is to change the internal structure of the steel, then improve the technical performance and service performance of the workpiece, tap the potential of the steel to burn out the equipment circuit, extend the service life of the parts, and further improve the product quality

heat treatment is a processing technology in which steel is heated to a predetermined temperature in solid state for a certain time, and then cooled down by some cooling method. Its technical process is: heating - insulation - cooling

the heat treatment technology of steel refers to the detailed technical parameters of heating, insulation and cooling of steel during heat treatment based on the microstructure transformation law of steel during heating and cooling due to small experimental force. There are many kinds of heat treatment technologies. According to the different heating and cooling methods, acquisition arrangements and properties, the heat treatment technologies of steel can be divided into: general heat treatment (annealing, normalizing, quenching and tempering), surface heat treatment (thermomechanical treatment, magnetic field heat treatment, etc.). Internationally, heat treatment can be divided into preparatory heat treatment and final heat treatment

in theory, the quenching temperature range of steel with a carbon content of 0.8% is about 750 ℃, which requires special attention. If it is not responsible for the shutdown loss of 3 billion yuan, the structural changes of steel cannot be achieved, and the heat treatment quenching will lose the desired effect

hot working steel is one of the indispensable process methods in the production of industrial products. It is mainly used in manufacturing and processing industries. It is used as a forming tool in combination with stamping, forging, casting and forming machinery, as well as forming machinery for plastic, rubber, ceramics and other non-metallic material products
