They are mixed powder particles composed of a variety of aggregates or aggregates and one or more binders. When used, they must be mixed with one or more liquids to be evenly mixed and have strong fluidity; shaped refractories generally refer to refractory bricks, which have standard shapes and can also be temporarily processed when built and cut according to needs. Refractory bricks can be divided into fired bricks, unfired bricks, fused bricks (fused cast bricks), and refractory insulation bricks according to the preparation process. They can be divided into standard bricks, ordinary bricks, special bricks, etc. according to shape and size. It can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical effects at high temperatures.
