Keywords: quenching, quenching agent, containing, polyvinyl alcohol, cooling, various workpiece, quenching liquid,

　　this quenching agent is supplied as a concentrated solution containing 10% ~ 12% polyvinyl alcohol. When in use, water should be added and diluted into aqueous solutions of different concentrations for quenching and cooling of various workpieces. The specific method for preparing quenching liquid is shown in the following formula:
　　M = NW/P
　　where: m is the weight of synthetic quenching agent concentrated liquid, kg;N is the concentration of quenching liquid to be prepared, see the weight of quenching liquid to be prepared, kg;P is the actual concentration of synthetic quenching agent,%.
