Using No-Cement Castable Instead of Firebrick to Prevent Rapid Expansion in Rotary Kiln Firebrick is a versatile product, but since refractories are not a commodity, there are applications where firebrick is effective... and applications where it’s ineffective. Recently, a project was completed to correct damage caused by the failure of firebrick installed by another refractory contractor. Our client’s process was super-heating EAF dust to extract the pure zinc that’s contained in the dust. The facility contained a large baffle wall located in the secondary unit, or chamber, off of the high temp rotary kiln. The original baffle wall was constructed with firebrick design. The brickwork failed in 6 to 8 months. The main failure mode was rapid expansion due to chemical attack. As you c
