Original abstract

Outdated machine for continuous casting of steel (CCM) has often fail to meet the requirements for produc-tion of the desired high quality carbon or stainless steel blank. Their control system acts as a so-called Black Box System, which provides operators the possibility of the system as needed to adjust and tune in order to achieve the required quality of steel produced. During the reconstruction of the caster is especially suitable to modify the secondary cooling, and slab CCM own rollways controlled cone possibly comple-mented well pronounced soft reduction. The necessary hardware modifications CCM cannot be designed without major upgrades the software control system based on the formation of new numerical models and their application to reduce of surface cracks and corners and central cavities or other defects. It was there-fore developed a series of numerical models in the form of modules, control modules and data visualization modules. Based on the model of the temperature field of the strand. The inclusion of modules in the control system CCM, which depends on the capabilities of the caster and customer requirements, can be built into the server embeddable the second levels of management. This server communicates via OPC protocol with superiors and subordinates systems. It also includes off-line simulator that allows you to test and simulate different cooling strategy and settings for different steel grades. The flexibility of such a solution is pre-sented for converting the caster with nine to thirteen engine cooling zones and optimizing the secondary cooling supported by on-line numerical optimization, the current temperature field slab. It is also demon-strated by the inclusion of a modular system management system CCM.

Zastaralý stroj pro plynulé odlévání oceli (CCM) má často nesplňují požadavky na výrobky a-ných požadované vysoce kvalitní uhlíkové nebo polotovaru z nerezové oceli. Jejich řídicí systém funguje jako tzv Black Box systému, který poskytuje operátorům možnost systému, jichž je zapotřebí k nastavení a naladit tak, aby se dosáhlo požadované kvality vyrobené oceli. Při rekonstrukci závodníka je zvláště vhodný k úpravě sekundární chlazení, a deska CCM vlastní válečkové tratě řízený kužel možná comple-zdokumentoval i výraznější snížení měkké. Nezbytné hardwarové úpravy CCM nemůže být navrženy bez velkých modernizace řídicího software systém založený na vytvoření nových numerických modelů a jejich aplikace pro snížení povrchových trhlin a rohů a centrálním dutin nebo jiné vady. Bylo to tam, přední vyvinul řadu numerických modelů ve formě modulů, řídicích modulů a vizualizace dat modulů. Na modelu teplotního pole provazce základě. Zahrnutí modulů v řídicím systému CCM, který závisí na schopnostech požadavků kouzelníka a zákazníka, může být zabudován do serveru integrovatelné druhých úrovních řízení. Tento server komunikuje prostřednictvím OPC protokolu s nadřízenými a podřízenými systémy. Obsahuje také off-line simulátor, který vám umožní testovat a simulovat jinou strategii chlazení a nastavení pro různé ocelí. Flexibilita tohoto řešení je předem prezentovány pro převádění kolo s devět-třináct motoru chlazení zón a optimalizaci sekundární chlazení podporované on-line numerické optimalizace, aktuální teplotního pole desky. Je také démon-zány zahrnutím modulárního systému pro správu systému CCM.
