Problems solved by technology
This method has the following disadvantages: the torque module has limited capacity and cannot provide greater tension. If the strip steel coil is large and the waste edge wire is long, the motor cannot provide sufficient power when the waste edge winding is too large, resulting in Waste edge silk loose roll
The torque motor controlled by the torque module is not easy to control during operation, and its torque cannot be increased with the actual situation. In actual production, it often occurs that the belt is broken due to excessive tension or the coil is loosened due to too small tension.

The invention relates to the technical field of steel rolling, in particular to a trimming coiler control system and a control method thereof. The system comprises a trimming coiler, a frequency conversion device, a controller and a transmission device. The controller is connected with the transmission device through the frequency conversion device. The transmission device is connected with the trimming coiler. The method comprises the following steps: setting and storing related parameters in a data storage module; performing turning moment accumulative calculation to obtain the current given turning moment M of the transmission device; controlling the frequency conversion device to control the working of the transmission device according to the current given turning moment M. The trimming coiler control system and the control method thereof provided by the invention guarantee that the force applied onto a coiler is a constant force and prevent the accident of trimming wire coil loosening or breakage by using a turning moment control mode.
Description
technical field [0001] The invention relates to the technical field of steel rolling, in particular to a control system and a control method for a waste edge coiler. Background technique [0002] Scrap edge treatment is the process requirement of cold-rolled strip steel production line, and scrap edge coiling is an important way of scrap edge treatment. In the production process of cold-rolled strip steel, efficient and well-run scrap coiling equipment not only contributes to the good operation of trimming equipment to ensure trimming quality, but also obtains good scrap coils, making scrap coils a The raw materials produced and processed by downstream manufacturers create additional profits for strip steel manufacturers. The drive of the traditional scrap coiler is a torque motor, and its controller is a torque module, which takes the current loop as the input and control object, so that a certain tension can be established between the scrap coiler and the trimmer for effe...
