Opis:: The validity of new ES legislation came into force in April 2013 and it assures identification and tracing of explosives from the explosive producers to the final consumers and thus there will be new trends in using new explosive materials produced in mixing and charging motorcars on the spot of consumption when minig mineral raw materials above/under ground.

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.
