一、前言65Mn 钢带年产量很大,冷轧中间退火是其生产过程中重要的工序之一,它直接关系到带钢随后继续加工的难易和最终热处理的质量优劣。65Mn 钢退火温度范围较狭,只经一次退火往往难以得到满意的球化组织。冷轧带钢退火时球化速度、生成相及其相对量与退火工艺关系如何?
I. Introduction 65Mn strip annual output is large, cold rolling intermediate annealing is one of its important processes in the production process, which is directly related to the subsequent strip steel and then continue the difficulty of the quality of the final heat treatment. 65Mn steel annealing temperature range is narrow, it is often difficult to obtain a satisfactory spherical structure only by an annealing. Annealing of cold-rolled strip nodular speed, the formation of phase and the relative amount of the annealing process how?
