优化水量，优化步距。尽可能的使型钢完整进入水区，加强现场通风，保证型钢进入水区前温度小于400℃。水冷时间不宜过长，因为冷却时翼缘为拉伸—压缩—拉伸过程.
Optimize the amount of water and optimize the step distance. As far ， the steel can be fully entered into the water area， and the field ventilation is strengthened. The temperature of the steel before entering the water area is less than 400. The time of water cooling should not be too long， because the flange of the wing is stretched， compressed and stretched.
轧件在冷床冷却过程中由于冷却水不能均匀分布在型钢表面，头部冷却速度较快，弯曲，冷床设备，形成浴盆状，使腹板上的积水不能流出，导致上表面收缩率明显大于型钢下表面，产生上弯。
为消除不均匀变形，首先应该使2辊压下量足够大，满足型钢塑变要求。消除型钢原有变形，达到统一的变形的目的。
Rolling in bed cooling process due to the cooling water can not be uniformly distributed on the surface of steel， the head of the fast cooling rate，冷床报价， the first bend forming tub shaped， make web water can not flow， resulting in the surface shrinkage rate was significantly higher than that of the steel surface，冷床， due to bending.
In order to eliminate the uneven deformation， first of all， the 2 roller should be large enough to meet the requirement of the type of steel plastic change. The original deformation of the steel has reached the goal of uniform deformation.
使冷床区域产生空气自然对流，形成烟囱效应，造成冷床上圆钢下部冷却速度过快，出现冷却不均匀，影响了产品的质量。步进翻转冷床利用步距与齿距的差值，使圆钢在冷床上每移动一个齿距，冷床设备生产，圜钢就滚动了一个角度，避免了圆钢在冷床上的不均匀冷却所造成的质量问题。
The cooling bed area of air natural convection， the formation of a chimney effect caused by the cooling bed bar lower cooling speed， appear uneven cooling effect of the quality of the products. Step by step difference of inverted cooling bed and pitch， the bar in the cooling bed every movement of a pitch， round steel rolling an angle， to **oid quality problems of round non-uniform cooling in the cooling bed caused by.
