Abstract

The need to adjust the monolithic refractories to increasingly severe and unstable Blast Furnace casthouse operating conditions has been a major challenge for refractory suppliers in order to guarantee the runner’s safety and its availability for operation. This paper presents the properties of a new robust single line Al2O3-SiC-C refractory castable developed to endure the severe operating conditions that main runners are facing in today's Blast Furnace casthouse scenario. Practical results during almost one year of testing revealed a significant lower wear speed of the new refractory lining when compared to a standard product.
