Effect of Quenching Medium-Concentration and Temperature on Cooling Rate of Quenching Fluid
1. The influence of concentration on cooling rate: the concentration is inversely proportional to the cooling rate, and the cooling rate decreases with the increase of concentration, whereas the cooling rate increases with the decrease of concentration. Therefore, if you want to increase the cooling rate, then add tap water to reduce the concentration, and vice versa, add quenching liquid concentration increases, cooling rate decreases.
2. The effect of temperature on cooling rate: Simply speaking, the higher the temperature, the lower the cooling rate; the lower the temperature, the higher the cooling rate. Therefore, in order to increase the cooling rate, the quenching agent can be cooled in production to reduce the temperature; conversely, heating or stopping the cooling cycle, increasing the quenching agent temperature, can reduce the quenching cooling rate.
3. The influence of agitation on cooling rate: agitating quenching fluid (packaging swing workpiece) can increase its quenching cooling rate; conversely, reducing quenching cooling rate
