制定了连续退火热循环制度,以便生产深冲冷轧低碳封顶钢钢带。这种热循环制度是由再结晶处理,配合水急冷的快速冷却和接着的时致处理所组成,由于急骤冷却可以在不到一分钟内就能实现充分的过时效,这与过去时效时间常常需要三十分钟到一小时成了鲜明的对照. 制定了水急冷工艺,以实现提出的热循环制度,采用冲掉带钢表面所形成的蒸汽薄膜的薄板喷水法,使随即急冷的带钢的完好形状能够得到保证。变形的原因是蒸汽薄膜不均匀的依附和消失。闸明了喷咀装置和操作条件例如喷头压力、水温和带钢移动速度的影响。
Developed a continuous annealing thermal cycle system, in order to produce deep-drawn cold-rolled low-carbon steel strip. This thermal cycling system consists of recrystallization, rapid quenching with rapid cooling of water, and subsequent time-dependent processing. Sufficient cooling can result in adequate over-aging in less than one minute, as is often the case with past aging times It takes 30 minutes to one hour to become a sharp contrast.Water quench process was developed to achieve the proposed thermal cycle system, using the thin strip of steam film formed on the strip surface water spray method, so that immediately quenched strip The perfect shape can be guaranteed. The reason for the deformation is that the steam film is unevenly attached and disappears. The effect of the nozzle arrangement and operating conditions such as nozzle pressure, water temperature and strip moving speed is clarified.
