Adoption of speeded changing could reduce the degree of carbide segregation more than 3 grades whereas repeated upsetting and drawing-out could only reduce 1-1.5 grades.
本文通过大量试验和机理的研究，高速钢锻件经过反复镦拔。只能降低炭化物偏析度1～1.5级。
The effective measures are presented bo avoid zonal segregation of carbide.
提出了避免碳化物带状偏析的有效措施。
