Refractories (Refractory material) according to the chemical characteristics can be divided into three categories: (1) acidic refractories (Refractory material). Acidic refractories (Refractory material) is RO2 (SiO2 ZrO2) as the main refractory component (Refractory material), refractory silica brick is typically acidic (Refractory material), in addition to zirconia products, semi-silica brick, clay brick, zircon products; Al2O3-SiO2-based material and Al2O3-SiO2-ZrO2-based materials are acidic refractories (Refractory material) refractory much money, such as: high alumina bricks, mullite brick, zircon mullite zirconium corundum brick and brick. Refractory plastic construction method using tamping refractory pug has a certain plasticity known as fire-resistant plastic. Refractory plastic generally made use of refractory clay embryoid wholesale, construction with pestle ramming cause plastic deformation without the risk of fragmentation or collapse refractories, can maintain the shape of the deformed after lifting force. Refractories distributor in the United States ASTM provisions determined by the plasticity index detector, the deformation index of greater than 15% were to be plastic, less than 15% were for ramming. In China International states: 15% deformation index - between 40% to be plastic. Strictly speaking refractory plastic should be a kind of semi-rigid plastic material wet. When the plasticity index greater than 40%, conformal bad, by ramming motions slump-prone, plasticity index of less than 15%, while prone to fragmentation ramming difficult tamping dense.
