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, conveying and discharging to the cooling bed rack, the temperature 900 DEG C to 100~300 C.

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.

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.
