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.

拉钢式冷床，其特点是利用单爪绳式或链式拉钢机，横向成批拖运轧件。这种拉钢机往往配备有潜行装置，以达到有选择性地拖运某一根（束）轧件的目的。潜行装置有两种形式：一种是杠杆式，另一种是滑块式。

Pulling type cooling bed is characterized by single rope or chain machine, horizontal rolling batch haulage. This kind of steel are often equipped with stealth device to selectively hauling a workpiece to root (beam). There are two forms of the lurking device: one is leveraged, the other is a slider.

针对角钢试生产初期冷床下钢发生倾翻的特点及原因，作业区技术人员指导岗位自己设计制作了防止角钢倾翻装置，通过冷床长度的测量及冷床裙板至冷床齿条距离，选定防止角钢倾翻装置的位置及长度，利用装置自身重力，从而实现角钢的稳定下钢，顺利进入冷床。

The needle angle steel trial production of steel bed early occurrence characteristics and causes of the tilting of the work area, the guidance of technical staff their own design to prevent angle tilting device, by measuring the cooling bed length and bed apron and bed rack distance, the selected angle to prevent tipping device and length of use of the device's own gr***ity in order to achieve the stability of angle steel, ***oothly into bed.
