THE IMPROVEMENT OF FUSED PERICLASE CRYSTAL SIZING METHODS
https://doi.org/10.17073/1683-4518-2014-11-50-55
Abstract
The new digital analysis is developed for microscopic investigation of fused periclase structure blocks which claims to be the objective estimation. The basic parameters distinguishing the devised method from the conventional linear chord definition method are shown. As an example the results for the fused periclase crystals manufactured by both «Magnezit» Group and other producers sized by new digital method and by the conventional methods are presented. The practical approval of fused periclase with more than 97,5 % MgO and various CaO/SiO2 ratio in the initial periclase-carbonaceous refractories discovered no influence of this parameter on the refractories behavior in the steel-teeming ladles' lining. Ill. 4. Ref. 5. Tab. 2.
