| Abstract: | Effect of filling ratio and melting speed on the quality of ESR ingot of H13 hot - work die steel was studied. Test result proved that appropriate increase of filling ratio and melting speed was propitious to the reduction of the mlcrosegregation of H13 hot - work die steel, so that the trausvesal impact toughness of the steel was improved. |
