摘要
研究了显象管玻壳模具用 4Cr5MoSiV1钢的不同热处理工艺下的组织与硬度的关系 ,特别是回火温度与硬度的关系 ,提出了预备热处理采用 1 1 0 0℃淬火 ,82 0℃回火的调质处理替代退火处理 ,随后经 1 0 2 0℃淬火 ,780～80 0℃× 4h回火 2次 ,并改善炉内温度分布状况 。
The relationship between hardness and the microsructures,especially between hardness and temper temperature of 4Cr5MoSiV1 steel used in the kinescope glass shell moulds during heat treatment processes were investigated. The result shows that the good structures and properties can be obtained by means of heating at 1 100 ℃,quenching by air, tempering at 820 ℃ as pre heat treatment replacing annealing,then heating to 1 020 ℃ and quenching again, after that,tempering at the temperature between 780 and 800 ℃ for 4 h twice, meanwhile, improving the temperature distribution in the furnace.
