Short Description:
Precast block also known as unshaped refractory prefabricated block, is mainly made of refractory castable and refractory plastics. Its classification includes castable prefabricated block and plastic prefabricated block; there are aluminate cement, water glass, Phosphoric acid and aluminum phosphate, clay binding and low cement binder prefabricated blocks; according to the type of aggregate, it is divided into high alumina, clay, siliceous and corundum prefabricated blocks; according to the molding method, it is divided into vibration molding and vibration compression molding And ramming and forming prefabricated blocks; the mass of prefabricated blocks is dozens of kilograms to several tons, so they are divided into large, medium and small prefabricated blocks; the prefabricated blocks are equipped with steel bars and anchors, so they are divided into ordinary prefabricated blocks and steel prefabricated blocks. Blocks and anchors prefabricated blocks, etc.
