冷床下料装置将其收集成组送至输出辊道上, 再由输出辊道将其送到冷剪剪切成定尺成品。冷床的设计质量与安装精度直接决定着产品的终质量。

The cooling bed feeding device collect group sent to the output roller, the roller output will be sent to the cold shear into thespecified product. Design quality and installation accuracy of cooling bed directly determines the final quality of the product.

工艺过程是：线材出精轧机后先入水冷导管进行急冷，冷却到650～750℃，经成圈器成圈后落入流态床中。流态床用流动的、导热性好的粒料(锆砂，含ZrO267.2%；SiO232.8%)作媒介，用鼓风机搅动这些颗粒呈悬浮运动状态，如同铅浴池中的铅液沸腾一样。Theflowbedisusedasamediumforflowing,goodthermalconductivityparticles(zirconiumsand,containingZrO267。

The process is as follows: after the wire is finished, the first step is to enter the water cooling pipe and then to cool it to 650~750 degrees. The flow bed is used as a medium for flowing, good thermal conductivity particles (zirconium sand, containing ZrO267.2%; SiO232.8%). The particles are stirred by the blower to move in suspension, just as the lead liquid in the lead bath is boiling.

潜行装置有两种形式：一种是杠杆式，另一种是滑块式。带潜行装置的拉钢式冷床很大优点足冷床床面利用率可达60%，可以自由地储存轧件，机动性能较好。

There are two forms of stealth device: one is lever type, the other is slider type. The biggest advantage of the pull steel cooling bed with stealth device is that the utilization rate of the cold bed can reach 60%, so that the rolling parts can be stored freely and the maneuverability is better.
