Abstract

Proizvodnja čelika u čeličanama također rezultira i nastajanjem većih količina troske kao proizvodnog ostatka. Tako dobivena troska može se primjenjivati u različitim granama industrije, ovisno o njenim svojstvima i sastavu, koji se dodatnim postupcima prilagođavaju specifičnim zahtjevima primjene. Toplinska stabilnost troske ovisi o sastavu i morfologiji, što je posljedica načina proizvodnje čelika i brzine hlađenja troske. U ovom radu je ispitana toplinska stabilnost uzorka troske dobivene u procesu proizvodnje niskougljičnog čelika u elektrolučnoj peći u kompaniji ABS Sisak d.o.o. Ispitivanja su provedena simultanom tehnikom toplinske analize, diferencijalnom toplinskom analizom i termogravimetrijskom analizom te su određeni temperaturni intervali gubitka mase.

Abstract (english)

Steel production steelworks results also in large amounts of steel slag as a byproduct. The resulting slag can be applied in different branches of the industry, depending on its properties and composition, which are tailored to the specific application requirements by additional procedures. Thermal stability of slag depends on its composition and morphology, which is a consequence of steel production process and cooling speed of slag. Therefore, the heat stability of the slag sample, obtained in the process of steel production in the electric-arc furnace in ABS Sisak d.o.o., was investigated in this work. Investigations were performed bysimultaneous thermal analysis, differential thermal analysis and thermogravimetry. Temperature intervals of loss of mass of slag sample were determined.
