Before steel materials are subjected to an appropriate heat treatment, they must be preheated. During this process scale is formed, which can be a problem in the proper heat treatment of the steel charge. The preheating process of the steel charge is carried out under specific conditions – parameters. These conditions determine certain properties of scale. One of the most important issues in this context, important from the point of view of the potential removal of scale from the charge surface, is the correlation of the heating process temperature and the adherence of the scale to the steel substrate. The paper presents the results of such research and their discussion. In addition, the methodology for measuring the scale adhesion to steel substrate is presented. Mathematical relations endearing impact of heating rate on the scale adhesion have been developed.
