Refractories variety is complete, covering common kinds on the market, according to different form, divided into shape and not stereotypes refractories, refractory, not stereotypes refractories and can be divided into two categories, can be plastic and castable.
Stereotypes refractories
Stereotypes refractories, is raw material, after pressing molding, after high temperature firing or unburned drying, established can't change the shape of refractory products, the resistance to high-tech stereotypes refractories containing chromium corundum composite brick, corundum brick, phosphate brick, brick of perlite and diatomite brick, lightweight mullite brick, etc. Convenient setting fire-resistant material selection and procurement, construction scheme of mature, is to choose the more types of lining refractory material. But stereotypes refractories with fixed size, more suitable for large area construction, such as small area around the corner range construction more difficult.

Don't finalize the design can be plastic
Don't finalize the design can be plastic, generally by the granular and powdered materials, combined with the plasticity of clay such as binder and made from a moderate amount of plasticizer, appearance is silly putty, have higher plasticity, long shelf life, formability, stability during the storage. Tech centers don't finalize the design can be in plastic represented by corundum silicon carbide can be plastic, its operation is simple, ramming performance good, impact resistant, high temperature resistance, wear resistance, suitable for target orientation Angle, etc.

Don't finalize the castable
Don't finalize the castable refers to a certain grain size distribution of refractory aggregate and powder, binder and additive mixture of refractory materials, also known as particulate refractories, has simple process, cost savings, is advantageous for the mechanized construction etc, solid durable, construction after the completion of the whole can be reduced in the process of using the well material wear, cracking, peeling, collapse and so on. In tech centers of resistance, steel fiber reinforced castable, corundum castble clay castable, silicon carbide wear resistant castable, etc, has been widely used in thermal technology equipment.
