摘要
以唐钢冷轧厂罩式退火炉内罩制作为例,阐述了在该产品的试制过程中采取的一系列创新。解决了大直径波纹筒不易调圆、对接尺寸精度难保、波纹轧制尺寸精度不足等技术难题。确保了制作的罩式退火炉内罩产品具有良好的气密性、稳定性、耐冷热骤变性、尺寸的精准性,完全满足冷轧全氢罩退的使用要求。
The series of innovation in trial production of inner cover of batch annealing furnace in Tang Steel Cold Rolling Mill are stated. The technical difficulties are solved such as making a large-size corrugated cylinder being round,guaranteeing precision of butt size,ripple rolling size being not enough precise. The made inner cover has good air tightness,stability,resistance to hot and cold shock,precise size and completely meets requirement of cold-rolling full-hydrogen batch annealing.
