Alumina based refractories are usually used in metallurgical furnaces and their thermal shock resistance is of great importance. In order to improve thermal shock resistance and mechanical properties of alumina based refractories short ceramic fibers were added to the material. SEM technique was used to compare the microstructure of specimens and the observed images gave the porosity and morphological characteristics of pores in the specimens. Standard compression test was used to determine the modulus of elasticity and compression strength. Results obtained from thermal shock testing and mechanical properties measurements were used to establish regression models that correlated specimen properties to process parameters.
Aluminozni vatrostalni materijali najčešće se koriste u pećima u metalurškom inženjerstvu gde je od izuzetne važnosti njihova termostabilnost (otpornost na termošok). U cilju poboljšavanja termostabilnosti i mehaničkih svojstava ove grupe materijala dodavana su kratka keramička vlakna. Karakterizacija mikrostrukture uzoraka određena je skening elektronskom mikroskopijom (SEM), a rezultati su korišćeni radi poređenja poroznosti i morfoloških karakteristika posmatranih uzoraka. Korišćena je standardna laboratorijska metoda određivanja čvrstoće i Jungovog modula elastičnosti. Dobijeni rezultati vezani za termostabilnost i mehanička svojstva poslužila su za formiranje modela koji povezuje svojstva uzorka sa procesnim parametrima.
