冷床主要有拔齿式冷床、齿条步进式冷床、拨爪式冷床、运载链式冷床、滚盘式冷床等。
将已轧制成型产品通过辊道输送进入冷床，再由齿条步进式拔齿等形式，将排列在冷床上的工件逐步移向冷床顶端，达到了工件的冷却效果。
The main bed tooth pulling type cooling bed, rack step type cooling bed, poking claw type cooling bed, carrier chain cooling bed, rolling disc cooling bed etc..
The rolling molding products through the conveyor into the rack cooling bed, stepping teeth and other forms, will be arranged in workpiece cooling bed is gradually moved to the top of the bed, the cooling effect of the workpiece.
冷床是轧钢生产中重要的辅助设备。冷床的作用在于将800℃以上的轧件冷却到150～100℃以下，同时使轧件按既定方向运行，在运输过程中应保证轧件不弯曲。由于轧制产品形状繁多相差悬殊，因此，轧钢车间的冷床型式是多种多样的。
The cooling bed is an important auxiliary equipment in steel rolling production. The bed is 800 degrees above the workpiece cooling to 150~100 DEG C, and make the operation according to the established direction, in the transport process should ensure the workpiece does not bend. Because the rolling shape of the product range of disparity, so the type of cooling bed steel workshop are diverse.
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。为适应不同型号、不同厚度的角钢，防倾翻装置的上有一个可以随时取放配重的斗壳，这样就可以实现不同型号、不同厚度角钢在裙板处稳定下滑。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.
