Embodiment Construction

[0010] The present invention will be further described below in conjunction with drawings and embodiments.

[0011] Such as figure 1 According to the technical characteristics of the narrow-strip five-stand tandem cold rolling mill, selecting high-performance control components is the key to meet the control requirements. As the control core PLC, the 3005 series CPU of VIPA Company was selected as the master station of the PROFIBUS system. The IM253DP slave station and a TP270 touch screen were installed on the main console. The S7-200 slave station and the DC control devices that simultaneously control 1~5# racks are installed with PROFIBUS expansion board MD24. # The IM253DP of VIPA Company is set as the slave station for the machine side operation box and the coiling operation table of the rack.

[0012] This set of PLC system uses VIPA's Speed ​​series CPU 315-2AG12 as the master station, and the number of slave stations has reached 16. As the master GPU 315-2AG12, the ...

Abstract

The invention discloses an electrical control system for a narrow strip steel five-stand cold tandem rolling mill. A VIPA 3005 series PLC of Germany and a CT irreversible all-digital direct-current speed regulation device MENTOR-II of England serve as control cores, cascade control over the speed and closed-loop control over tension are achieved, all performance indexes of equipment and a productare greatly increased, and the obvious economic benefits are obtained. The electrical control system applies PROFIBUS communication, wire arrangement between cabinets and between operating platforms is omitted, the system failure rate is greatly decreased, meanwhile, a good man-machine picture is set on the main operating platform, and convenient is provided for failure overhauling by a customer.

Description

technical field [0001] The invention relates to an electrical control system for a five-stand cold continuous rolling mill for narrow strip steel, which is suitable for the mechanical field. Background technique [0002] There is a very good market for cold-rolled narrow-strip steel, but the rolling mill equipment in many factories is relatively old, especially the electrical installation level and control performance are poor, which directly affects the product quality, yield and output, and of course also affects the company's profitability. economic benefits. Contents of the invention [0003] The present invention proposes an electrical control system for a narrow-strip five-stand cold tandem mill, with the German VIPA 3005 series PLC and the British CT irreversible full-digital DC speed regulating device MENTOR-II as the control core, realizing cascade control of speed and tension The closed-loop control has greatly improved the performance indicators of equipment an...
