Abstract
V okviru diplomskega dela je obravnavana metoda vrednotenja življenjskega cikla LCA, sodobnega orodja za analizo, vrednotenje in oceno življenjskega cikla proizvodov, procesov in storitev. Kratko je predstavljen standard upravljanja z okoljem ISO 14001, ter standardi družine ISO 14040, splošna načela in pravila za vodenje in vrednotenje študije LCA, ter uporaba na področju proizvodnih tehnologij s posebnim poudarkom na področju proizvodnje visokokakovostnih jekel za protibalistično zaščito, na primeru jekla PROTAC 500 največjega slovenskega proizvajalca jekla. V okviru dela sta izvedeni kompleksna analiza in vrednotenje življenjskega cikla ter SWOT analiza debele pločevine iz jekla PROTAC 500. V okviru izvedene študije smo analizirali in ovrednotili emisije v zrak pri treh glavnih procesih izdelave jekla PROTAC 500 v neposrednem industrijskem okolju proizvodnih obratov največjega slovenskega proizvajalca jekla: procesu izdelave jekla v električni obločni peči in vlivanje v slabe na napravi za kontinuirno litje, ogrevanju slabov v potisni peči in vročem valjanju slabov na plošče debelin od 6 do 25 mm. Količine emisij so logično visoke in so seveda direktno povezane s količino proizvedenega jekla. Količine proizvedenih jeklenih plošč so bile v letih 2010, ko se je pričelo z industrijsko proizvodnjo jekla PROTAC 500, pa do leta 2015 do maksimalno 100 ton na letnem nivoju. V letu 2016 je proizvodnja narasla na 1487 ton, v letu 2017 pa je že presegla mejo 2000 ton na letnem nivoju. Izvedeno delo je prispevek k dvigu produktivnosti in izboljšanju kakovosti ter doprinos k področju varstva okolja in zmanjšanju porabe energije in surovin.

Title:Implementation of life cycle assessment tools into the field of the armour steel semiproducts
Abstract:
In the context of the graduation thesis, the method of life cycle assessment LCA, a modern tool for analysis, evaluation and assessment of the life cycle of products, processes and services, is discussed. The ISO 14001 environmental management standard and ISO 14040 family standards, the general principles and rules for managing and evaluating the LCA study, and the use in the field of production technologies with special emphasis on the production of high-quality steels for anti-ballistic protection, in the case of PROTAC 500 steel by the largest Slovenian producer of steel, are presented briefly. Within the framework of the thesis, a complex analysis and evaluation of the life cycle and SWOT analysis of thick sheet metal made of PROTAC 500 steel were made. Within the framework of the conducted study we analysed and evaluated the emissions into the air in the three main processes of PROTAC 500 steel production in the direct industrial environment of the production plants of the largest Slovenian steel producer: the steel production process in the electric arc power furnace and the casting into slabs on the continuous casting device, reheating of slabs in push-type furnace and hot rolling of slabs on plates of thickness from 6 to 25 mm. Emissions are logically high and, of course, directly related to the amount of steel produced. The quantities of steel plates manufactured in years from 2010, when the industrial production of PROTAC 500 steel started, to 2015 were up to a maximum of 100 tons per year. In 2016, production increased to 1487 tonnes, and in 2017 it already exceeded the 2000 tonnes on an annual level. The thesis is a contribution to raising productivity and improving quality and a contribution to environmental protection and reduction of energy, and raw materials consumption.
