Abstract

The paper deals with porosity of metallurgical sinter. It is aimed at the research on relation between porosity and reducibility of sinter. It evaluates the relation between these two properties in economical point of view of pig iron production. In the introduction, the paper sums up international experience with testing of materials porosity. It defines main qualitative properties of metallurgical sinter beside porosity such as its reducibility and disintegration in relation with porosity determination. In the main part, the paper presents results of porosity tests. It describes the experimental method used for it and conditions for it. There is compared porosity of samples with high and low reducibility. The effect of porosity on reducibility is studied. It is interpreted on the economics of production process. The effect of porosity sinter characterized with indicator of reducibility on gas consumption during pig iron production is presented.

Keywords: Porosity, reducibility, economics of pig iron production, non-direct reduction
