中型轧钢车间生产的各种钢材，冷拉采购，经轧钢机轧制后由热锯机（或剪切机），冷拉，切成定尺长度，还需要冷却到常温，再进行矫直。轧制后的热轧件冷却时，由于连续生产，一般都是在缓慢的横向移动过程中逐渐冷却的。这种使轧件横向移动并冷却的设备，叫做冷床。
All kinds of steel produced in medium rolling mill are cut by hot saw (or shearing machine) after rolling mill， and it is cut into length of fixed length. It also needs to be cooled to normal temperature and then straightened. After rolling， the hot rolled parts are cooled down gradually because of continuous production. The equipment for rolling and cooling the workpiece is called cold bed.
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，圣霖冷拉， will be arranged in workpiece cooling bed is gradually moved to the top of the bed，冷拉报价， the cooling effect of the workpiece.
冷床是中小型棒材车间不可缺少的辅助设备之一。它的功能是将轧机轧制后经飞剪剪切成倍尺长度的棒材， 输送并卸到冷床齿条上冷却， 使其温度由900℃降至100 ～ 300℃。
The cooling bed is one of the auxiliary equipment in the ***all bar workshop indispensable. It is the function of the bar rolling mill after double length flying shear， conveying and discharging to the cooling bed rack， the temperature 900 DEG C to 100~300 C.
