摘　　要：我国高附加值模具钢的成材率一直落后于世界先进水平。本文在对国内某厂生产模具钢成材率偏低的问题进行理论分析之后,通过采用矩形断面、大高宽比与锥度、减小帽容比、优化尾部形状与轧制规程等优化设计,在保证质量的前提下,使模具钢的成材率提高到了83.51%。The yield of high value-added mold steel has been lagging behind the world advanced level in China. The issue of low yield rate of mold steel in domestic factory was analyzed. Some design methods were adopted, including rectangular section, large ratio of height and width and taper, capacity decrease of ingot hot top, tail shape and rolling schedules optimization, etc. The yield was raised to 83.51% on the premise of guaranteeing the quality.
