| Abstract: | The casting microstructure and ingredient distribution of the high chromium steel roll were investigated. By means of comparing these data with Thermo-Calc for Windows (TCW2) software analogue and unbalanced solidification phase, the solidification process was systematically analyzed under the condition of centrifugal casting. Meanwhile, the variation of as-cast microstructure during heat treatment was also summarized so as to improve the component of roll, control the mill rolls' casting microstructure and optimize the roll heat treatment process. |
| Keywords: | roll high chromium solidification heat treatment |
