1.轧制过程中，冷床作业人员严禁上冷床，不准在辊道、齿条上行走。
2.生产中出现乱床等事故，必须等停轧以后进行处理清出。
3.冷床取样要使用专用工具进行取样。
4.作业中应注意观察周围的情况，无关人员严禁进入大冷床的***区域。
5.因乱床等事故造成的热废品，当班必须清出，确保冷床周围的环境整洁。
1. in the process of rolling, cooling bed workers strictly on bed, don"t walk on the roller rack.
2. in the production of random beds, such as accidents, must wait after the stop rolling process to clear out.
3. bed to use a special tool for sampling sampling.
Should observe the situation around 4. operati, unrelated pers non dangerous region in the cold bed.
Waste heat 5. bed because of chaos caused by the accident, the duty must be clear, to ensure the surrounding environment clean bed。
二小型作业区型材改造试生产过程中，通过冷床裙板自重式防止角钢倾翻装置的设计及应用，在小角钢的收集过程中，省去了在移钢小车处人工将角钢翻正操作，压缩了了冷床输出的时间，有效防止因角钢倾翻而影响钢材的输出节奏，实现了冷床正常稳定的下钢。
Two ***all work area profile transformation production process, prevent the inclination angle of design and application of double bed apron device by gr***ity, in the process of collecting ***all angle, eliminating the need for moving steel trolley artificial angle righting operation, the output of the compressed cooling bed time, effectively prevent tilting angle and effect of output rhythm of steel, the steel cooling bed under normal and stable.
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，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, 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.
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。Shouldobservethesituationaround4。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，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.
