Effect of heating technology on scale adhesion in the steel charge heating process
Abstract
The adhesion of scale to the steel substrate is an important parameter in the charge heating process before plastic processing. A low value of adhesion adversely affects the operation of heating furnaces, while too high value causes the scale to roll into a steel product and deteriorate its purity and quality. The paper presents the methodology of adhesion determination and the results obtained on the basis of the presented methodology. The influence of heating technology on adhesion for constant furnace efficiency and different values of excess air ratio is discussed. The furnace efficiency and the excess air ratio are the basic parameters of the process. It is extremely important in the context of the challenges of optimizing production processes, which in turn is an important element of the circular economy.
