Opis:
The quality of refractory materials plays an important role especially in high temperature processes. In case of violation of qualitative properties of refractory materials, the safety of the use of the technological equipment in which these materials are used is compromised. The requirements on the quality of refractories and their properties are now high, as their operating life should be as long as possible. The aim of the article is to point out the quality of refractory material in contact with corrosive media, to analyze the technological factors that affect the quality and safety of technological equipment. An analysis of the refractory material, as well as the analysis of the melt was performed. Subsequently, an experiment was realized, which was evaluated by macroscopic analysis and chemical analysis. After the experiments, we found that the melt had penetrated the masonry and consequently created corrosion layers in the masonry. These layers have affected the life of the material and reduced the safety of the technological equipment in which they were used.

Opis:
This paper is a file of analytical information with intent to summarize so far known knowledge and to anticipate new development and possibilities of improving oxygen converter lining. Technological methods currently used in steel production put high requirements for the quality parameters of used refractory building materials. The article pursues the analysis of balance thickness of the magnesium-carbon refractory lining of basic oxygen furnace during the campaign. Development and innovation of the technologies of steel production is also reflected in increment of the requirements for magnesium-carbon refractory materials for basic oxygen furnace linings. Permanent increment in steel production has substantial influence on the refractory materials consumption in the worldwide scale. Specific methods proceedes during refining process of scrap material as quick temperatures alternation, changes in slag composition or impacts of heavy pieces of scrap material, influences destructively the basic lining of basic oxygen furnace. The static crucible corrosion test, as a simple experiment, is very useful for study of these processes because a direct observation of refractory – slag reactions in real systems is impossible. For that reason, corrosion crucible tests were adapted so that carbon basic refractories was isolated from the atmosphere by high alumina cast able cover. For such reason the high accent is put to the charge of refractory lining during the campaign which is connected with permanent increment of gunning repair refractory materials consumption. Continual increment of refractory bricks quality leads to the prolongation of time of the basic oxygen furnace campaigns.
