Abstract

Kombinat Magnezit JSC has developed a process for manufacturing densely sintered large-grain periclase-lime powders that are resistant to hydration due to formation of enclosing films on the surface of the grains. A performance test of pitch-impregnated periclase-lime converter refractories at the Krivorozhstal’ Works has shown their advantages over dolomite-periclase refractories. The service life of a converter lining produced from the test powders was increased from 690 to 946 heats.
