冷床是冶金轧钢行业对轧制产品（螺纹钢、园钢、钢管等）有效进行冷却的工作台面。冷床由机械传动系统、水冷却系统、冷床工作台面、固定支架等方面组成。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。

The cooling bed is metallurgical industry of rolled products (steel, steel, steel and other garden) effectively cooling the work surface. The cooling bed by mechanical tran***ission system, water cooling system, cooling bed table, etc. of fixed bracket. 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.

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.

优化水量，优化步距。尽可能的使型钢完整进入水区，加强现场通风，保证型钢进入水区前温度小于400℃。水冷时间不宜过长，因为冷却时翼缘为拉伸—压缩—拉伸过程.

Optimize the amount of water and optimize the step distance. As far , the steel can be fully entered into the water area, and the field ventilation is strengthened. The temperature of the steel before entering the water area is less than 400. The time of water cooling should not be too long, because the flange of the wing is stretched, compressed and stretched.

中型轧钢车间生产的各种钢材，经轧钢机轧制后由热锯机（或剪切机），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.
