1. Generally, the water-soluble quenching cooling medium decreases with temperature rise, and the hardening oil is enhanced when the temperature increases, and the cooling capacity is not changed. The polymer quenching cooling medium such as a PAC quenched cooling medium, the additive and water will be separated at 78 ° C, so the use temperature should have a range.
2. The pressure of the quenching cooling medium has a significant effect on cooling capacity.
3. The flow and cooling ability of the quench cooling medium is proportional to the relationship, and the baffled quenching workpiece is immersed in a stationary liquid, but can still be heated on the surface of the workpiece meter, and when the liquid moves immediately complete the workpiece quench, the quenching cooling medium is, the larger the flow rate, the larger the flow rate of the quench cooling medium, The greater the cooling ability.
4. The additive content is directly affected by the cooling capacity, the higher the content of the polymer quenching cooling medium, the lower the cooling capacity, and thus the content of the adjustment of the polymer quenching cooling medium can obtain different cooling speed, so that the cooling ability of the quench cooling medium Changes between water and oil.
