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，冷床， 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.
冷床是中小型棒材车间不可缺少的辅助设备之一。它的功能是将轧机轧制后经飞剪剪切成倍尺长度的棒材， 输送并卸到冷床齿条上冷却， 使其温度由900℃降至100 ～ 300℃。
The cooling bed is one of the auxiliary equipment in the **all bar workshop indispensable. It is the function of the bar rolling mill after double length flying shear，冷床设备， conveying and discharging to the cooling bed rack， the temperature 900 DEG C to 100~300 C.
当流态层温度为250℃时，奥氏体分解温度为550～600℃，冷床哪家好，同铅浴淬火相似；当流态层温度为300℃时，奥氏体分解温度约为500℃左右，比铅浴淬火还低。
When the temperature of the flow layer is 250 C， the austenite decomition temperature is 550~600， similar to that of lead bath quenching. When the flow state temperature is 300， the austenite temperature is about 500 C， which is lower than the lead bath quenching.
