(2) neutral refractories (Refractory material). Neutral refractories (Refractory material) mainly refers to R2O3 (Al2O3, Cr2O3), and atom mineral crystal (SiC C B4C BN SI3N4) as a main component of refractories (Refractory material) refractory low, such as corundum brick, charcoal brick, silicon carbide brick, boron carbide refractories (Refractory material), boron oxide refractories (Refractory material), nitride refractories (Refractory material) and so on. Steel fiber reinforced refractory castable to a certain size heat-resisting steel fiber (length of about 20-35mm refractories, cross-sectional area of ??approximately 0.13-0.2cm2) mix by adding refractory aggregate, binders and additives consisting of castable refractories (Refractory material), known as the steel fiber reinforced refractory castable. With no heat resistant steel fiber castable refractories compare agents, 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 refractory castable materials and heat-resisting steel fiber varieties, but only five kinds of grades more widely adopted, the 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.
