Abstract：In order to reduce the oxidation burning loss of 08Al slab，the effects of different heating conditions（atmosphere composition and temperature）on the oxidation kinetics of 08Al were investigated by simulating the high temperature oxidation process of 08Al slab. The results showed that the oxidation burning loss greatly decreased with the decrease of p(O2). When the volume fraction of O2 was less than 1%，the burning loss reduced by more than 70%. On the condition of 4% O2，the temperature decreased from 1 250 to 1 200 ℃，and the burning loss of 08Al steel decreased by 12%. Thus，reducing the p(O2) ratio was more effective in reducing the billet oxidation burning loss compared with reducing the temperature.
