Abstract: 

Preheating in steel industries is defined as a treatment during which different steel profile is continuously heated up to the hot working temperature. One of the most important side effects in this process is surface oxidation or "scaling". Furthermore the adhesively of oxide scales on the slab surfaces is considered as a crucial factor. In the present investigation, using a new concept, the effects of chemical composition and the interface morphology on the scale adhesively of three different low carbon steels are studied. The results indicate that the presence of Si leads to interface "Fayelite" phase formation, which tends to strengthen and increase the adhesively. More over it was observed that the interface roughness would enhance the mechanical adhesively.
