| 摘 要： | 为研究连续退火工艺,开发冷轧钢种,开发了一种新型连续退火模拟实验机.该实验机采用单片试样,在有N2,H2保护气氛的密闭环境中进行退火.实验过程中,利用大电流对试样进行直接电阻加热,采用喷气/喷雾组合窄缝喷嘴进行冷却,并可对试样施加张力;加热、冷却、张力和气氛可按设定的工艺参数控制;整个退火过程在一个工位上完成,试样不需要移动.介绍了实验机的设计原则、系统结构、特点以及主要技术指标.性能测试结果表明,退火后的试样,其组织和力学性能均匀性及重现性均比较好.

| Abstract: | A new simulator was developed to investigate continuous annealing processes and develop cold-rolled steel grades,on which the close annealing process in N2/H2 protective anmosphere is available with sheet pieces as specimens.During simulation the specimen may be tensioned with a hydraulic cylinder resistance-heated at high current and cooled by narrow-mouth nozzles for high-speed jetting/spraying,and the heating,cooling,tensioning and composition of atmosphere were all controlled according to preset paramet... |
