[0002] Refractory bricks are generally divided into two types, namely amorphous refractory materials and shaped refractory materials. Amorphous refractory materials, also known as castables, are mixed powder particles composed of multiple 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 refractory materials generally refer to refractory bricks, which have standard shapes and can also be temporarily processed when cutting according to needs. Molding devices are required during the processing of refractory brick blanks.
