What kind of castable has a long service life for the kiln mouth of a rotary kiln?
Several years ago, steel fiber corundum castable and high-alumina castable were used for the kiln mouth of the rotary kiln, but the results were not satisfactory. They were prone to cracking and had poor thermal shock resistance, resulting in a short service life and increased costs. Refractory castable is composed of aggregates, powders, binders, additives, water, and other liquid materials. Under high-temperature conditions, it exhibits good sintering performance, volume stability, corrosion resistance, and high-temperature mechanical properties. The refractory lining at…
