Embodiment 1
[0020] According to the volume percentage of 5:95, glycerol (chemically pure) and distilled water are made into glycerin aqueous solution, and the following additives are added (by weight percentage of glycerol aqueous solution): 0.04% anti-aging agent; 0.1% anti-rust agent; 0.01% defoamer; 0.4% cooling rate regulator. Above-mentioned anti-aging agent is salicylic acid; Antirust agent is borax; Defoamer is Polyethylene Glycol (average molecular weight is 400); Cooling rate adjuster is polyvinylpyrrolidone (average molecular weight is 1300000), uniformly mixed by mechanical stirring Prepared as a quenching cooling medium and allowed to stand for 24 hours.
[0021] Three different quenching media were tested with a type quenching cooling rate tester. It was found that in the high temperature zone (pearlite transformation stage), the cooling rate of the 5% glycerol quenching medium was faster than that of quenching oil; in the low temperature zone (martensite) transformation sta...

[0024] According to the volume percentage of 3:97, glycerin (chemically pure) and distilled water are made into glycerin aqueous solution, and the following additives are added (by weight percentage of glycerin aqueous solution): 0.04% anti-aging agent; 0.1% anti-rust agent; 0.01% defoamer; 0.4% cooling rate regulator. Above-mentioned anti-aging agent is salicylic acid; Antirust agent is borax; Defoamer is Polyethylene Glycol (average molecular weight is 400); Cooling rate adjuster is polyvinylpyrrolidone (average molecular weight is 1300000), uniformly mixed by mechanical stirring Prepared as a quenching cooling medium and allowed to stand for 24 hours.
[0025] Three different quenching media were tested with a type quenching cooling rate tester. It was found that in the high temperature zone (pearlite transformation stage), the cooling rate of the 3% glycerin quenching medium was faster than that of quenching oil; in the low temperature zone (martensite) transformation sta...
