The M18 Single Disc Of Copper Casting Machine Control System Research And Design

Copper has been widely used in such industries as mechanism, electronics and chemistry for its conductivity, diathermancy, ductility and rot-proof-ness. Copper casting wheel is an important part of copper smelting. In china, some metallurgical enterprises use foreign equipment, whose prices are more than three times as much as the domestically produced equipment, taking up a large fixed assets. Therefore, the research and development of the quantitative copper casting wheel system disk have great significance for copper smelting enterprises.Based on the technological transformation of Jinchang Smelter——old M18 casting equipment, we learn from similar imported equipment and update it to design a new set of control system. In order to effectively control the exact casting quantity of the anode plate, the weight of casting uses the approach of dual-mode fuzzy control, using the different weights of the casting packages as input, the servo position sensor signal as the feedback signal, and the dumping speed of casting packages as output to form a dual-mode fuzzy control:when the weight of a deviation is greater than a threshold, we can make use of proportional control to improve the system response; when the bias is reduced below the threshold, we can use the fuzzy control to improve the system's damping performance to reduce the overshoot.The control system mainly consists of IPC (IPC), programmable logic controller (PLC), the drive components with PLC control system as its core and the control measure casting, disc operation, the anode plate enhance and translation as coordination. Disk drive motor and pan motor use frequency control to achieve good control of speed and improve the operating characteristics of the system. The software of the system includes PC system monitoring software and slave PLC control program. According to the process of the equipment, the system uses STEP 7 V5.4 software and "structured programming" approach to complete PLC program. Besides, the system uses WINCC configuration software to design a monitoring program for monitor and management. The control system uses PROFIBUS-DP Field-bus and Industrial Ethernet, setting up the communication technology within the system and realizing the exchange of information.As it is reported, this new system can effectively overcome the quantity error of the anode plate and enhance the stability of the disc in order to satisfy the demand of real operation.
