轻压下和拉速对42CrMo钢410 mm x 530 mm铸坯轧成Φ195 mm材的低倍和中心C偏析的影响
The effects of soft reduction (0 ~ 8 mm) and casting speed (0.42 ~ 0.49 m/min) of cast bloom on macrostructure and segregation of 42CrMo steel Φ195 mm rolled product are tested. The results show at present process condition that when the superheat degree of 42CrMo steel is controlled at 20 ~ 30℃ with secondary cooling specific water content 0.3 L/kg
mold and end electromagnetic stirring 100 A/l.5 Hz and 400 A/8 Hz
the casting speed 0. 49 m/min and the total soft reduction 6 ~ 8 mm
the internal quality of 42CrMo steel rolled product can be efiectively improved.
