Effect of furnace efficiency on scale adhesion in the steel charge heating process

Abstract

The paper presents the results of research on the influence of the efficiency of a metallurgical heating furnace on the adhesion of scale formed during the heating process of the steel charge. The methodology for measuring the adhesion of scale to the steel substrate as well as the measurement stand by means of which the research plan was carried out were presented. In addition, the method for determining the heating curves for selected furnace performance and measurement results are presented. The calculation results demonstrating the effect of efficiency on scale adhesion are summarized.
