1 foreword to adjust industrial structure further, raise the economic benefits of company of the group that bring steel, by Wuhan designing institute the design builds 6 shed machine of Xiaofang base Lian Zhu June 2000 complete of put into production, more large-scale technical reformation is passed twice again after, technology of system of this project automation advanced, price is reasonable, moving performance on the safe side, rate of electric appearance unifinication is high, move a few years to come, moving effect is very good all the time, produced steel to amount to 800 thousand tons 2003. Function of system of 2 PLC automation introduces a basis to produce the demand of craft, automation system cent is one class automation and control of 2 class automation, among them one class automation is fundamental automation class, it is a whole report / appearance unifinication controls a system, every shed even casting machine the controller of S7-300 series PLC that sets subsidiary of Ximen of a Germany, public facilities uses a S7-400 PLC, electromagnetism agitate system uses the PLC of ABB company, 1 ～ 3 flow, systems of 6 control of face drifting fluid have 4 ～ each a S7-300 PLC, set two CRT additionally to operate a station, its configure ark graph to be like attached drawing. Attached drawing deploys even system of casting machine automation the graph the main effect of one class automation, it is the logistic control that completes each technology plant and operation, the 2 indication that are status of craft parameter, facility mix the setting; of craft parameter call the police the monitoring; that reachs technological process picture the 3 communication that are process control and computer. Is the main characteristic of this system: ? Unifinication of appearance of? of Mei of take along sth to sb is designed, the construction is strict, automation rate is high, ability of data processing of S7 series PLC and logistic operation ability are very great, process designing is agile, interference rejection capability is strong, use safeguard convenient etc. (Vector controls the 6SE70 series that the stage of packets of 1) drive part is machine, large to pulling correct circumgyrate, vibrating motor facility that needs timing introduces Xi Menzi company frequency control device, the inverter of silicon controlled rectifier that electromagnetism agitate uses Swedish ABB company to produce cabinet group. (2) casting machine answers revolving stage the function of public PLC is big packets to wrap Gai Sheng to fall apply turn rent a car among control; walk, litre fall; of dynamoelectric valve control turns interconnected system of water system of engine of Lian Zhu of; of control of system of hydraulic pressure of; of control of control; fan. (3) casting sheds vibration of PLC function crystallizer to control; to pull correct machine to procrastinate move control; to bring ingot lever drive to control; cut car to control; casting to shed roller path to procrastinate move 2 cold water of control; to control; breakdown to call the police etc. (4) CRT operates station picture to use software of configuration of Wincc of Xi Menzi product, are its main is the function: ? Canister of the phlegmy Jie that seek Zhuang asks    technological process of  Ru? to the picture shows; breakdown calls the police the picture shows, forms for reporting statistics is printed and graph of process value trend shows etc. The system controls cent to move control and maintenance to control 3 kinds of fashion for automata, hand. Automata cent is process computer control and electric automata two kinds. After selection process computer controls fashion, pilot set value comes from 2 class computer. After choosing electric automation to control fashion, the system is finished automatically by PLC program, systematic operation and set buy come from CRT to operate a station. Choice hand changes control way, have the aid of operates station and work station to undertake operating at CRT. This kind of means controls monomer device normally. In maintenance means falls, select switch is hit beside machine, the site that basically is used at equipment is debugged with maintenance. Of 3 systems perfect with in improving the moving process in casting machine, according to spot circumstance and the change that craft asks. We also are done to certain respect in real time perfect and improve measure further. If a transducer controls roller of mould adobe blocks of instead of 3 machine that pull correct,use; of device of a frequency control to be opposite alone 24V dc system undertakes more detailed press kind respectively power supply controls; to those who increase partial process to be worth is in on Wincc picture show and trend, these improve the proof in running practice is to be beneficial to Lian Zhu to move normally and go to the lavatory of machine the maintenance of equipment is safeguarded. System of control of PLC of this casting machine runs 4 last words up to now, casting base surface and in-house quality satisfy craft requirement completely, for me the factory developed diversity of structure of breed steel, stimulative product successfully to produce main effect, also obtained very considerable economic benefits.
