  • Types of Heat Treatment Process
    For high chromium balls containing more than 10% chromium, it is necessary to quench and then temper them. For large low chromium balls with less than 10% chromium content, tempering is required. (The specific process depends on the customer's heat treatment process)

  • Types of Heat Treatment Process
    In addition, there are three quenching methods: water quenching, oil quenching and gas quenching. For grinding balls, the latter two methods are the best. In addition, gas quenching is more suitable than oil quenching for ultra-high chromium spheres. However, oil quenching is most suitable for mills with chromium content between 10 and 18%.
  • Types of Heat Treatment Process
    Quenching process: First, the grinding ball is heated to a certain degree within a specific time, and then it is directly quenched in oil or air for several minutes.
    Tempering process: the quenched grinding ball is heated to a certain extent for a period of time.
  • AUTO PUSH ROD TYPE HEAT TREATMENT MACHINE
    Push-rod heat treatment is the most popular equipment in grinding medium heat treatment process, because it is not only flexible, but also very energy saving. The daily output of ordinary high chromium grinding medium ranges from 10 tons to 30 tons. The whole conditioning process requires only two operators.
  • AUTO PUSH ROD TYPE HEAT TREATMENT MACHINE
    The machine is controlled by PLC and the operator can modify the temperature of each section by touching screen according to the process requirements. The ball heating and hardening process is fully automatic. The machine is equipped with an alarm system, which can clearly tell the operator the working cycle and machine failure information.
  • AUTO PUSH ROD TYPE HEAT TREATMENT MACHINE
    Working Process
    Quenching part: grinding ball - grinding ball into the furnace - preheating - heating - insulation - pushing ball out - quenching (oil or gas) - grinding ball
    Tempering part: ball loading (original or quenched)- Push the ball into the furnace - heating - push the ball out - packaging
