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.
