Effect of Oxidation Temperature to Descaling Properties of the Scale Formed on Silicon Containing Steel

Abstract:

Article Preview

Silicon is an effective element to improve steel hardness by solid solution hardening. However, it is difficult to remove the scale formed on high Si contained steels. In the present study, descaling tests were carried out with three heat patterns of oxidation treatments to make clear the effect of oxidation temperature on descaling properties of the scale formed on Si containing steel. Two-step heating at 1210 °C-1140 °C shows the best descaling results. Descaling properties should be influenced by scale morphology and structure at the scale / steel interface. Furthermore, the results of present study suggest that fracture behavior of the scale, which is controlled by voids and cracks, is also important factor for descaling properties.
