为适应不同型号、不同厚度的角钢，防倾翻装置的上有一个可以随时取放配重的斗壳，这样就可以实现不同型号、不同厚度角钢在裙板处稳定下滑。

In order to adapt to different types and different thickness of angle steel, the andumping device has a  shell that can be taken and counterweight at any time, so  different type and thickness angle steel can slide steadily at the skirt plate.

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。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。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。

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.

流态冷床法的基本原理是：利用一定速度的气流吹动沸腾床上的固体颗粒，使之处于悬浮运动状态，依靠煤气在流态层中的燃烧，使流态层具有要求的温度，线材从中通过时冷却，完成奥氏体的分解转变。

The basic principle of the flow state cold bed method is that the solid particles on the fluidized bed are blown by the flow of gas at a certain speed, so that it is in the state of suspended motion, depending on the combustion of gas in the flow state, the flow layer has the required temperature, and the wire is cooled when it passes through, and the  and transformation of the austenite is completed.
