The chill roll freezes the molten plastic to the substrate almost instantaneously, therefore it must have an adequate water cooling system.
冷却辊轴几乎能瞬间把基材上的热容胶体冻结，因此它必须要有合适的水冷却系统。

In the event of a stall, immediately open the roll gap and turn off the cooling water.
在轧机发生事故时，应快速打开轧辊间隔，关掉冷却水，去掉辊身上卷曲的带钢。

The strip temperature model calculates the temperature increment caused by roll deformation and the strip's cooling temperature after it is being rolled.
