NEW ROBUST MAIN RUNNER REFRACTORY CASTABLE FOR SEVERE BLAST FURNACE OPERATING CONDITIONS: NEW ROBUST MAIN RUNNER REFRACTORY CASTABLE FOR SEVERE BLAST FURNACE OPERATING CONDITIONS

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.
