.¦µ100/320 ¡Á 300 Four-high Cold Rolling Mill Control System

Cold-rolled laboratory establish the level of the level. Influence the development ability of the new products of company and possibility to meet the demands of new products directly. This laboratory is on the basis of already having SG-300 four rollers of cold calender. Carry on the related transformation. And the laboratory construction that carry on. The cold calender is modern machine , typical representative of the electricity , integrated system of liquid. Its level of control's level, Will influence the result of use of this rolling mill and properties of product directlyThis paper in roller department elasticity out of shape to consider rolling mill and at the partial foundation, Establish the system of rolling mill model, At studying hydraulic composition and foundation to control method of control system; it benefits and analyzes the mathematical models of the hydraulic control systems of various influence factors in rolling course to set up; Regard rolling model as the target, has analyzed the dynamic characteristic of the position control system.Require according to model and system , has controlled some designs Rolling mill hydraulic pressure pigeonhole, down, automatically control and monitoring system adopt PLC , Company of AB , realize first class control, The computer realizes the data are gathered and second control of the man-machine interface, Transfer speed allocate Siemens direct current transfer and fit rapidly systematicallyThis software uses Windows98 as its O.S, Utilize development software RSview32 and RSlgox500 software of AB Company to carry on the development of the control system, Utilize the programming way facing target , carry on module treatment of all functions, the maintainability of the procedure is good, The result shows: The software interface is friendly, easy to operate...
