本文论述了低合金16Mn(HP)钢板,采用不同的控制轧制工艺参数、形变温度(即轧制温度),其次选择合理的形变量及冷却速度等。使钢在r相区再结晶以下及r+α双相区域进行较大变形。以获得细化铁素体晶粒,增加晶粒中的位错密度和细小亚晶的组织结构。从而提高屈服强度,保持塑性(韧性)不变。此工艺应用于冶金工业生产,不但改善产品质量,并可免去热处理,缩短生产周期等,具有显著的社会经济效益。
This paper discusses the low alloy 16Mn (HP) steel plate, using different control rolling process parameters, deformation temperature (ie, rolling temperature), followed by the choice of a reasonable amount of deformation and cooling rate. The steel is recrystallized in the r-phase zone and r + α two-phase zone for greater deformation. To obtain refined ferrite grains, increasing the dislocation density in the grains and the microstructure of fine subgrains. Thereby increasing the yield strength, maintain the plastic (toughness) unchanged. The process used in metallurgical industry production, not only to improve product quality, and can be removed from heat treatment, shorten the production cycle, with significant socio-economic benefits.
