Abstract
An on-line intelligent control method for the cooling characteristics of a quenching liquid in heat treatment production includes the steps of: step 1: subjecting a workpiece to thermal insulation; step 2: measuring the cooling characteristics and the heat transfer coefficient of a quenching liquid followed by correction; step 3: starting cooling; step 4: then changing the internal circulation rate; and step 5: removing the workpiece. This scheme can effectively avoid the problem that the cooling of a workpiece in industrial production deviates from the ideal cooling characteristics of a quenching liquid obtained in a laboratory.
