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，冷床设备生产，头部冷却速度较快，弯曲，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， 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.
该冷床设备主要用于轧后钢板在线缓慢自然冷却。在型材生产线上，冷床哪家好，冷床对型材还具有预弯曲功能，防止型材在自然冷却过程中因各处质量不等导致出现不规则弯曲。应用领域：冷床主要应用在钢铁行业、冶金行业等。
With the cooling bed equipment is mainly used for rolling steel platesonline slow natural cooling. Profile production line has the function of cooling bed pre bending profiles， prevent profiles in the natural cooling process of the entire qualityranging from lead to irregular bending. Application: bed is mainly used in the iron and steel industry， metallurgical industry， etc.
明确轴向位置，加大矫直压力。不要单独打8辊轴向，调整侧弯时应以每相临的3个辊为一个调整单元，保证矫直稳定性。侧壁斜度的处理措施是经常注意检查各辊轴向位置，窜动情况。注意在不同间隙情况下，冷床价格，矫直力的选取。对H2与H3的测量做到每批抽查，以做到及时调整。
The axial is clearly defined and the straightening pressure is increased. Do not play the 8 roll axis alone. When adjusting the side bend， 3 rolls per phase should be used as an adjustment unit to ensure the straightening stability. The treatment of side wall slope is to check the axial and movement of each roll. Pay attention to the selection of maximum straightening force under different clearance conditi. The measurement of H2 and H3 is done in each batch， so as to adjust it in time.
