Method and apparatus for measuring the quenching intensity of liquid quenching baths

摘要

There is obtained a continuous rapidly responding and controllable measurement of the quenching intensity of quenching baths. A test body is inserted into the bath and a controlled heating is applied to a portion of the surface of the test body raising the temperature of that portion of the test body surface to a constant temperature of 50 DEG to 700 DEG C., especially 150 DEG to 400 DEG C. higher than the temperature of the bath. The heat energy required to maintain this temperature constant is used as a measure of the quenching intensity of the bath.
