Application of water-soluble polymer quenching medium in vacuum quenching
　　People have tried to use water-soluble polymer as quenching medium in sealed box type multi-purpose furnace and vacuum quenching furnace . the test shows that the carbon potential of the furnace and its control are not adversely affected by using water-soluble polymer pantan fire medium, and the quenching quality is improved and the environment is equivalent to oil quenching, the cost is slightly reduced. The application of water-soluble polymer quenching medium in vacuum quenching has opened up a new way for the tools and molds made of vacuum water quenching carbon steel.
