Monolithic refractories by a certain size grading refractory aggregate and powder, binder, admixtures and become refractory materials, also known as scattered refractory materials. Monolithic refractories are used for the lining of thermal equipment. They can be baked directly without firing. Compared with firebrick, monolithic refractories have a simple process (because of eliminating the burning process), energy saving, low cost, easy to mechanized construction and other characteristics, in some thermal equipment to use the effect is better than firebrick.
