Abstract

The metal product is cooled by a liquid consisting of suspended and/or dissolved substances whose presence ensures heat transfer conditions permitting most of the optinal allotropic transformation of the material constituting the metal product to be effected. The liquid is heated to a temp higher than 75% of its b. p in degress C. Specifically the liquid is an aqueous saline solution, preferably saturated or supersaturated.
