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.

矫直板位于冷床入口侧, 由制动裙板拔入的轧制棒材首先落到矫直板上, 使棒材保持大平直度。矫直板每块长1. 15m, 宽250mm , 上有10个齿形, 块与块之间只留出动齿条移动间隙, 安装在定支架上。

The straightening plate is located on the inlet side of the cooling bed, and the rolled bar pulled by the brake apron first falls on the straightening plate to maintain the maximum flatness of the bar. The straightening plate is 1. 15m long and 10 250mm wide. There is only a movable clearance between the block and block, which is installed on the fixed support.

拉钢式和往复多爪推齿式两种冷床对于圆钢都不太适用，容易拉斜、滚乱。冷却圆钢（管坯）以使用链式冷床较好，上钢一厂、大连钢厂的650轧钢车间都采用链式冷床，两者所不同之处在于：上钢一厂的圆钢搁在台架上，链条拉着圆钢缓慢前进，由于圆钢单重较大，一般不会乱滚。大连钢厂的圆钢直接搁在链条上，前进过程中圆钢与链条无相对运动。Application:bedi***ainlyusedintheironandsteelindustry,metallurgicalindustry,etc。两种链式冷床使用单位反映都较好。

The two kinds of cooling beds, pulling steel type and reciprocating multi tooth type, are not very suitable for round steel. Cooling round steel (Guan Pi) to use the chain type cold bed is better, the 650 steel mill of Shanghai steel factory and Dalian steel mill use chain cold bed. The difference lies in that the round steel in the first steel plant is on the bench, the chain pulls the round steel slowly forward, because the single weight of the round steel is larger, it will not roll out. The round steel of Dalian steel plant is directly placed on the chain, and there is no relative movement between round steel and chain during the progress. The use unit of the two types of chain cold beds is better.
