Plastic refractory has fairly good plasticity and is suitable for casting construction. Mouldable plastic refractory is produced by mixing quantitative refractory aggregate, power, fireclay, binder, and other additive and squeezed to brick green body shape. Plastic refractory still has good plasticity when properly packed and stocked for a certain time. RS Castable Refractory Supplier can provide you with high-quality plastic refractory.

Plastic Refractory Materials
According to different kinds of plastic refractory composition aggregate, plastic refractory can be classified into high alumina plastic refractory, fireclay based, corundum, silica, magnesia, chromite, zirconia, carborundum plastic refractory, etc. Plastic moldable refractory is a great solution when refractory castable and bricks are too complicated or cumbersome and formwork is unavailable. Plastic refractory possesses excellent strength and high density, as well as abrasion, slag, and spall resistance can be used in a wide range of applications.
For plastic refractory application, ramming plastic refractory is also resistant to molten metals, which makes it perfect for applications such as boiler work, forge furnaces, tundish linings, ladle linings, burner blocks, and patches.

Plastic Refractory Applications
Plastic refractory features good thermal resistance, easy and convenient for construction. Moldable plastic refractory is applicable to various heating furnaces, soaking pit, annealing furnace, blast furnace, is also available for arc furnace lid, high-temperature furnace nozzles and so on. According to alumina content, plastic refractory can be classified into different grades for different applications. RSA-45 is ceramic bonded plastic refractory designed for rapid repairs to brick and monolithic lings while RAS-80 is a chemically bonded plastic refractory that is mainly used for capping and on the spouts in electric induction furnaces.
