The Reformation Of Production Automation System For Han Gang 3500mm Plate Rolling Mill

With China’s rapid economic development, China’s iron and steel degree of automation has also undergone huge changes, the rolling technology automation and process has made considerable progress. The one hand, the rolling process parameters with the different needs of the users do more optimization, on the other hand, users need more variety and higher quality. Therefore in order to cope with the complexity of the market demand, the steel mills, spare no effort to rolling equipment and technology, a full range of upgrade and renovation in order to achieve the purpose of maximizing production efficiency.Handan Iron and steel production line automation system is outdated and not very efficient to meet the different needs of individual users, design the transformation of their production to higher efficiency and the steel mills in various stages of production, and design appropriate transformation problem, and the introduction of some new equipment, upgrading of some hardware, improved software. Through the transformation of the entire automation system to improve the level of control of the device, the yield of the steel mills, the quality has reached a higher level, and has important practical significance for reducing energy consumption.In this paper, Hebei Handan Iron and Steel 3500 mm Plate transformation, its full range of automation transformation. In basic automation L1,area of rolling area and finishing equipment upgrade at the same time, the best large may be old devices make full use of its various parts of the control functions easier operation and maintenance, and good completed the basic part of the control task, while Siemens Win CC configuration software to develop a simple and practical PC monitoring system, to complete the display of real-time parameters, process parameter setting, dynamic curve show.L2 process control computer system transformation from the furnace area, and the line equipment mill area, the shear zone, and finishing zone, from the furnace before the feeding roller until the Storehouse collecting device. The entire heavy plate partition production line process tracking and control. The process control computer selection of technically advanced and sophisticated equipment, in compliance with the principle of universal, open, high speed, reliability, ease of upgrade and expansion in the structural design of the hardware system, add new items to the need to adapt to the next. At the same time to achieve process optimization control, technologically sophisticated mathematical models are selected in the control area of process control computer.
