摘要: Magnesia- carbon (MgO-C) refractory bricks have been used in the slag line of ladles due to its superior penetration resistance and excellent thermal shock at high temperatures. However, life this has become limited on prolonged use poor oxidation as well low strength Thus, physical chemical properties MgO-C refractories could be improved by addition suitable additives micron or nano range. Magnesium aluminate (MgAl2O4) spinel recognized one most effective material wear resistance. The particle size distribution MgAl2O4 is also important factor that influence both refractories. Hence, present work deals with improvement
