Quenching process skills of ከፍተኛ ድግግሞሽ ማጥፊያ ማሽን

1. Adding salt to the water can double the cooling rate: the cooling rate of salt water quenching is fast, and there is no phenomenon of quenching cracks and uneven quenching. It can be called the most ideal coolant for quenching. The proportion of salt added is preferably 10% by weight.

2. Impurities in the water are more suitable as quenching liquid than pure water: adding solid particles to the water can help to clean the surface of the workpiece, destroy the effect of the vapor film, increase the cooling rate, and prevent the occurrence of quenching spots. Therefore, it is a very important concept to use the quenching technology of mixed water instead of pure water for quenching treatment.

3. The polymer can be mixed with water to form a water-soluble quenching liquid: The polymer quenching liquid can be prepared according to the degree of water added to the quenching liquid with the cooling rate from water to oil, which is very convenient, and has no fire, pollution and other.
