Plant for water treatment and distribution for non-contact cooling of reheating furnace

Ovaj rad obuhvaća detaljan postupak projektiranja automatizacije sustava za postrojenje koje obrađuje i distribuira vodu u cilju beskontaktnog hlađenja peći. U uvodnom dijelu objašnjen je princip rada programabilnog logičkog kontrolera te struktura od koje se sastoji. Također, detaljno je opisan postupak projektiranja u programskog alatu TIA portal te je obrađen proces stvaranja vizualizacije signala i konfiguracije alarma na HMI sučelju. Glavna tema u diplomskom radu obrađuje koncept rada cijelog postrojenja u automatskom i ručnom režimu rada te su definirani uvjeti rada pojedinih dijelova postrojenja u cilju sprečavanja neželjenih stanja. U završnom dijelu rada prikazana je simulacija koja daje detaljan uvid u samu vizualizaciju rada postrojenja.This paper covers a detailed process of designing the automation of a plant system that processes and distributes water for the purpose of indirect cooling of the walking beam furnace. The introductory part explains the principle of operation of a programmable logic controller and the structure of which it consists. The design process in the software tool TIA portal is described in detail and the process of creating signal visualization and alarm configuration on the HMI interface is clarified. The main topic in the thesis deals with the concept of operation of the entire plant in automatic and manual mode and defines the operating conditions of individual parts of the plant in order to prevent unwanted conditions. The final part presents a simulation that provides a detailed insight into the visualization of the plant operation
