Unshaped refractories, also known as bulk refractories, are refractories made by mixing refractory aggregate with certain grain size grading and powder, binder and admixture. It is usually used for the lining of thermal equipment, directly baking and heating without burning process. Compared with refractory bricks, it has the characteristics of simple process (because the firing process is omitted), energy saving, low cost, and convenient for mechanized construction. The effect of using amorphous refractory on some thermal equipment is better than that of refractory bricks.
