Expert System Research For Steel Making Dynamic Scheduling

In the last few years, with the progressive development of computer technology and intelligent control, more and more new technique and progressive methods applied in the production. They give new activity and opportunity of survival for enterprise's developing. Enterprises can pay attention to energy conservation and emissions reducing, cleaning production and resource reuse during the production run.Currently full continuous casting and non straight carbon steel is way for reducing, increasing private benefits and remaining survivability in Number One Steel Works. How to guarantee the rationality and validity between convertor and casting machine is a very very important work. At present, In number one steelmaking, the production directing is with the help of experience. Production can be much influenced by human factor. Although plenty researches and practice have been done with many countries'iron and steel enterprises and scholars. Yet it is also an investigative key point.The course of steel manufacture is a high temperature, high pressure, swift, changeable, complexity and uninterrupted system. Various procedure parameter, frequency changes of different kinds of factors, remarkable non-linearity, time variant, spatial distribution and determinacy. Production process is interfusion, balance and control among physical condition transition, flow of matter control at time, temperature and space. Syntaxes and match between material circulation states are of great importance. There are sequential processing relation, material circulation balance, equilibrium of stock, energy balance and time balance among each process.This paper introduces the subsystem of converter and casting machine,collected and analyzed the steel manufacture,through the linear programming got scheduling production organization model, got more reasonable production organization modes by further optimization. This system can comprehensive the typical scheduling rules, analyzed the control for steel manufacture and correlated data with expert control system. Optimization objective is the shortest change over time between convertor and caster. The aim is science dispatch, possible arrangements, reducing dissipation of energy best matching between convertor and caster, the cohesive strategy of converter and casting machine matching has been realized,giving full play to the production capacity of convertor and caster, to protect quality and quantity molten steel giving to continuous caster, more heats for continuous caster, integration control, reduce enterprise cost, increase private benefits and marketability.Through system emulation come to the expect aim. production dispatch system better realized fundamental strategy of expert dispatch with manual intervention control.It supplied beneficial support for training newlywed persons, supplying production early warning information, reducing labor intensity, decreasing accident, optimizing production flow. System obtained the good result with the economic performance.
