The Principle of Heat Extraction with the use of Liquid Single Organic Polymers is as follows:

      When hot metal is immersed in these single polymer quenchants a film of liquid organic polymer is deposited on the hot metal as it contacts the diluted quenching fluid. The speed of the quenching rate depends on the thickness of the deposited coating. The thickness of this coating is regulated by the concentration of polymer in the quench bath. As the hot metal is cooled to below the separation point of the polymer, the liquid organic polymer drops off the hot metal and again becomes soluble in water.
      It is because of the above listed mechanism that quenching equipment be designed properly to allow for the best possible quenching system to insure good results on the materials being hardened.
      The purpose of this report is to help with the design of quenching systems which will be used with single polymer quenchants.

INTRODUCTION
The design principles which will be incorporated in this report are meant mainly for the heat treatment of ferrous metals. We are aware of the fact that certain heat treating applications may require quench systems which must be tailored to the individual process. This report is designed to cover 85% to 90% of the quenching systems utilizing single polymer quenchants.
