Zero-Carbon Tempered MgO – ZnO Brick as Alternative of Fired Magnesia Chrome for Safety Lining of Stainless Steel Ladle

New environment-friendly processes and the reduction of pollutant emissions are the new driving force of the steelmaking industry. Magnesia chrome bricks fired above 1,700°C are used in the safety lining of stainless steel ladle due to its higher physical and mechanical properties and dimensional stability. Tempered bricks were developed using a special binder system that eliminates the firing process and CO2 emissions. The new brick is based on MgO-ZnO with free chrome and carbon. Properties and performance results of fired and tempered brick used in the safety lining of the stainless steel ladle will be presented in this paper.
