Refractory plastic construction method using tamping refractory pug has a certain plasticity known as fire-resistant plastic. Refractory plastic are generally made of mud embryoid use, when to use the ram ramming construction will produce plastic deformation without the risk of fragmentation or collapse, can maintain the shape of the deformed after lifting force. In the United States ASTM, the provisions with plasticity index detector when measured refractory deformation index of greater than 15% were refractory to how much money can 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% of refractories manufacturers, prone to fragmentation when ramming difficult tamping dense. Steel fiber reinforced refractory castable to a certain size heat-resisting steel fiber (length of about 20-35mm, cross-sectional area of ??approximately 0.13-0.2cm2) mix by adding refractory aggregate, binders and additives consisting of pourable refractories (Refractory material), known as the steel fiber reinforced refractory castable. Compared with non-heated heat-resisting steel fiber castable, such castable has the following characteristics: (1) inhibit castable in conservation, the use of high-temperature baking and produce hand shrink. (2) increase the castable toughness, resistance to mechanical shock resistance and mechanical strength. (3) improve the thermal shock resistance of castable. (4) to prevent micro-cracks generated in the castable or extensions extend under thermal stress and mechanical stress which lead to cracking or peeling. Now used to enhance heat refractory castable materials and more varieties of steel fiber refractory sales, but only five kinds of grades widely used, its alloy composition and performance table below. Generally below 1000 ℃, castable lining one side of body heat is the use ME304 and ME430 grades of stainless steel fiber reinforced, while above 1000 ℃, is the use of ME446, ME310 and ME330 heat-resistant stainless steel fiber reinforced grades.
