摘要
钢材在辊道运输需要停止或改变方向时,大多使用挡板。为了实现钢材和挡板的软接触,采用变频控制匀减速原理,以西门子PLC、变频器为基础开发了有一定泛用性的辊道控制程序块。在实验室利用PLC模块、变频电机、变频器等组成的试验装置,模拟实现了辊道减速的整个过程,钢材与挡板达到了软接触。
In most circumstances the back plate is used to make steels stop or change direction in roll table transportation. To realize the soft contact between steels and plate, the principle of uniform deceleration by frequency conversion control is used. With Siemens PLC, frequency transformer, the universe -purpose roll table control program model is developed. In laboratory with test device composed of PLC model, frequency transformer and frequency conversion motor, the whole procedure of roll speed reduction is simulated, the soft contact realized.
