The effect of condition of the charge surface on the scale adhesion for excess air combustion

Abstract

In the process of heating steel the processes of chemical interaction occur between the furnace atmosphere and the surface of the steel being heated. Great importance, in aspect of course of the oxidizing process equal as well as for phenomenon of scale adhesion on the charge surface, condition of his surface has. Roughness is parameter defining condition of surface. The methodology of investigations of scale adhesion in work was presented. The methodology of measurement of roughness surface was introduced. Influence of surface roughness on the scale adhesion was described. The paper presents correlation of the scale adhesion but roughness of surface.
