| 摘 要： | 高速钢钢锭锻前加热质量对后续的锻造工艺影响至关重要,对M42高速钢钢锭的锻前加热工艺进行了研究。理论计算了M42钢的晶界熔化温度和变形加热温度,结合生产经验设计试验方案,将试样在不同的加热工艺下加热,然后对加热后的组织进行观察分析,从而得出最理想的锻前加热工艺。研究结果表明,M42钢锭最优的高温保温段加热工艺:1 150℃×5 h,为实际生产应用提供理论参考。

| Abstract: | The heating quality of H.S.S.ingot before forging is very important to the following forging process, the heating process for M42 H.S.S.is researched.The most ideal before-forging heating process is got from:calculating in theory the grain boundary melting temperature and deforming heating temperature for M42 steel, designing test plan combined the production experience, heating the samples under different heating processes, and then viewing and analyzing the heated structure.It is showed from the research that the best high-temperature holding section heating process for M42 ingot is 1 150 ℃×5 h.This conclusion can offer a reference for actual production. |
