二小型作业区型材改造试生产过程中，通过冷床裙板自重式防止角钢倾翻装置的设计及应用，在小角钢的收集过程中，省去了在移钢小车处人工将角钢翻正操作，压缩了了冷床输出的时间，有效防止因角钢倾翻而影响钢材的输出节奏，实现了冷床正常稳定的下钢。
Two ***all work area profile transformation production process, prevent the inclination angle of design and application of double bed apron device by gr***ity, in the process of collecting ***all angle, eliminating the need for moving steel trolley artificial angle righting operation, the output of the compressed cooling bed time, effectively prevent tilting angle and effect of output rhythm of steel, the steel cooling bed under normal and stable.
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。Application:bedi***ainlyusedintheironandsteelindustry,metallurgicalindustry,etc。
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.
