Abstract

In heat treatment the cooling process is the most critical phase for the quality of the products. Knowledge of cooling is a prerequisite to be able to tackle problems like form changes and crack risks, as well as to predict the results of the heat treatment through computer calculations. Industrial cooling is commonly done without direct action on the cooling process. In this project a number of methods have been investigated, where it is possible to influence the cooling rate during the cooling process. The methods that gave the greatest influence were ultra sound, moving of the parts, and interrupted cooling, respectively. Three computer programs for PCs have been tested and compared with the results from hardening of test rods. The differences between the programs were great, and the most expensive program gave the best result
