Abstract

A new method for increasing the cooling capacity of a fluidized bed is presented. It is based on the principle that the heat liberated during the quenching of parts is absorbed by the evaporation of water within the fluidized bed. The spraying of the sample surfaces with water during cooling in a fluidized bed proved to be a useful alternative to salt-bath cooling for isothermal treatments, provided that the transformation temperature is significantly higher than the evaporation temperature of water. The bainitizing of low-alloy high-carbon steel parts is discussed as an example.
