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.
冷床主要有拔齿式冷床、齿条步进式冷床、拨爪式冷床、运载链式冷床、滚盘式冷床等。
将已轧制成型产品通过辊道输送进入冷床，再由齿条步进式拔齿等形式，将排列在冷床上的工件逐步移向冷床顶端，达到了工件的冷却效果。
The main bed tooth pulling type cooling bed, rack step type cooling bed, poking claw type cooling bed, carrier chain cooling bed, rolling disc cooling bed etc..
The rolling molding products through the conveyor into the rack cooling bed, stepping teeth and other forms, will be arranged in workpiece cooling bed is gradually moved to the top of the bed, the cooling effect of the workpiece.
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.
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.
