Refractories and Industrial Ceramics

Zonal changes have been studied for a refractory mix of OAO Kombinat Magnezit (Satka) on reaction with melt in the open-hearth process. Four zones of change are isolated. In successive zones there is a reduction in MgO content in the material and a relative increase in the amount of CaO, TiO 2, Al 2O 3, SiO 2, and Fe. In this direction there is an increase in feruginosity of periclase and an increase mix porosity, melt and substitution solid phases appear. These changes reduce refractory mix resistance and promote its breakdown. © 2011 Springer Science+Business Media, Inc. Source

Refractories and Industrial Ceramics

A new method is considered for using heat insulation material offered by the OOO Ogneupor Trade Group company during steel pouring into a mold. The technical result of using the new method consists of a reduction in surface defects and those within the macrostructure of an ingot, abandoning use of an exothermic mixture, and a simultaneous reduction of heat insulation material consumption. © 2011 Springer Science+Business Media, Inc.
