热轧圆钢冷床夹尾装置——制动轮系统,系瑞典中央·莫格斯哈马公司(Centro-Morgardshammar)设计、制造的定型产品。该装置为一滚筒,安装于成品轧机之后,冷床之前。高速运行的钢材从端部导嘴进入以一定速度旋转的滚筒,这个滚筒起制动作用,使轧件减速并停止下来,然后将其送入冷床。该装置制动精确度较高,在轧件速度为25m/s时,即可在±100mm范围内使其停止。例如:当成品线速为25m/s,根据 S自由=(V~2)/(2gf) Hot-rolled round steel bed clamp device - brake system, the design and manufacture of Centro-Morgardshammar, Sweden. The device is a roller, installed in the finished rolling mill before the cooling bed. High-speed running steel enters the drum rotating at a constant speed from the end nozzle. This drum acts as a brake to decelerate and stop the rolling stock, which is then fed to the cooling bed. The device has high braking accuracy and can be stopped within ± 100 mm at a rolling speed of 25 m / s. For example: when the finished wire speed is 25m / s, according to S freedom = (V ~ 2) / (2gf)
