以首钢京唐2250mm热轧为例,对卷取机芯轴速度控制和张力控制原理进行了详细的分析,重点介绍了速度控制与张力控制的切换以及TMDrive—50逆变器在芯轴调试过程中应该注意的关键点。卷取机是热轧生产线核心设备之一,处于生产线末端,对钢卷收集起着关键作用。首钢京唐2250mm热轧共采用3套地下卷取机。本卷取机是三辊式卷取机,带有踏步控制。在液压控制下,卷取机芯轴可以膨胀和收缩。该芯轴在传动侧以两个双排轴承支撑,而在运转时,操作侧则以外置轴承支撑。在电动机和卷取机芯轴之间装配一个齿轮
Taking Shougang Jingtang 2250mm hot rolling as an example, the paper analyzes the principle of winding speed control and tension control in detail, mainly introduces the switching of speed control and tension control and the commissioning of TMDrive-50 inverter in mandrel Should pay attention to the key points. Coiler is one of the core equipment of the hot rolling production line, at the end of the production line, plays a key role in the coil collection. Shougang Jingtang 2250mm hot rolled a total of 3 sets of underground coiler. This coiler is a three-roll coiler with step control. Under hydraulic control, the winding mandrel can expand and contract. The mandrel is supported on the drive side by two double-row bearings, while in operation the external bearings are supported on the operating side. Assemble a gear between the motor and take-up mandrel
