| Abstract: | The DIL402C thermal dilatometer, STA449C thermal analyzer, the type Gleeble-1500D thermal simulation testing machine were employed to test the linear expansion coefficient, major phase change temperature, mechanic properties at high temperature of 2Cr13. The effect of these properties at high temperature on surface quality of billet and the mechanism of surface depression and micro - crack formation on billet were analyzed. The study showed that heat transfer performance of mold fluxes for 2Cr13 stainless steel was vitally important. |
