531X305NTBANG1 專爐控制系統(tǒng)面置

Special furnace control system: each converter body, loose feed, waste heat silver furnace, flue gas purification with 1 PLC and 1 operating station, converter body common part, blower room, gas recovery and mine transport with 1 PLC and 1 operating station. The 1# and 2# converter are each equipped with 1 server. The control system configuration of the converter is shown in FIG. 1.
The control system connection network has four layers: 1, device network (DeviceNet/ProfiBUS); 2. Control network (residual ontrolNet) : 3 factory level management network (EtherNet/P); 4. Local city network (EtherNet/IP), the network is set in the main control room of the converter, in order to network the 10 operating stations and servers of the 2 converter in the main control room of the converter. The equipment network connected to the field equipment has DeviceNet and ProfiBus, such as the oxygen gun inverter and the 6KV medium voltage inverter of the gas blower directly communicate with the PLC through the equipment network card. All 1#/2# converter and common part PLC, operation station and server use ControlNet to connect more than one control network to realize PLC, operation station and server data sharing and real-time delivery
The casting machine and refining furnace are replaced by an independent ContrlLoix control system. The plant level management network (EtherNet/P) connects the server of the converter, continuous casting machine and LF fine furnace control system with the level management machine and scheduler to realize the exchange of main production and energy data, and provides scheduling and decision data for the plant level management and scheduler. Each operation station and server of converter adopts DELL medium and high-end commercial computer. The system platform of the server and operating station is Windows2000(server/client edition), the monitoring software of the operation station is RSView32, the PLC configuration software is RSLogix5000, and the network configuration software is RSLinx(ControlVet/DeviceNet). The operation screen of the converter body is shown in Figure 2 >
The #/2# converter is equipped with a server in the main control room, which is used for network management, user login control, production data management, report printing, communication of the upper management network, software development and maintenance of professional engineers. Lay the foundation for realizing ERP function. Servers can also be used as operation stations in production.
