Abstract
Tračnice čine osnovu svakog sustava kolosiječne konstrukcije, te ostvaruju direktni kontakt s kotačima željezničkih vozila. S obzirom na preuzimanje vrlo velikih dinamičkih opterećenja vozila, vrlo je važno osigurati visoku kvalitetu tračnica u procesu proizvodnje. Kroz ovaj rad obuhvaćena je tematika procesa proizvodnje i kontrola kvalitete željezničkih tračnica. U uvodnom dijelu prikazan je povijesni razvoj tračnica te je objašnjena njihova važnost u današnjem svijetu. Također dane su osnove informacije o tome što su zapravo tračnice, osnovni oblici tračnica, dimenzije i primjena. Nadalje je detaljno opisan sastav čelika za proizvodnju tračnica i sam proces industrijske proizvodnje tračnica. Prilikom preuzimanja tračnica od strane naručitelja potrebno je voditi računa o kvaliteti proizvoda. U svrhu kontrole kvalitete koristi se norma HRN EN 13674-1, koja kao obavezan europski standard donesen od strane Europskog povjerenstva za normizaciju, te proizvođačima nameće pravila osiguranja kontrole i kvalitete proizvodnje. Normom su definirana osnovna ispitivanja Vigneolovih tračnica linijske mase 46kg/m i više, koja obuhvaćaju kvalifikacijske testove, testove prihvatljivosti te kontrolu unutarnje i površinske kvalitete tračnica. U radu su navedena osnovna pravila te ograničenja za svaku vrstu ispitivanja, te u kratko prikazana ispitivanja profila tračnica.
Abstract (english)
Rails are a basic component of every railway track structure, which is in direct contact with rail vehicle wheels. Due to significant dynamic load of rail vehicles, it is of utmost importance to assure high rail quality in production process. The paper discusses the topic of production process and quality control of rails. In introduction, historic development of rails is explained together with their role in modern world. Basic information about rails, their shape, dimensions and application are given. Further, rail steel composition as well as rail production process are described. Prior to rail installation, quality check must be presented to client by the rail manufacturer. To provide quality control procedures, a standard HRN EN 13674-1 is published by European Committee for Standardization – CEN in order to provide unified rules for assuring rail quality. The standard defines basic tests for Vignole rails 46kg/m and above, which include qualification tests, acceptance tests as well as internal and surface quality checks of rails. the paper defines basic principles and constrains for each type of test and presents test examples of certain rail profiles.
