| Abstract: | Technical proposal of alloy structure steel 42CrMo from converter smelting, LF +RH refining and bloom continuous casting, and the test result were introduced. The production practice shows that the surface quality is good, the segregation of composition rate cab be controlled at 0.96～1.03,the center porosity and center segregation is ≤1.0, T[O]≤15×10-6，and [H]≤1.8×10-6。 |
