Refractories characteristics chart
In materials science, a refractory (or refractory material) is a material that is resistant to decomposition by heat, pressure, or chemical attack, and retains strength and form at high temperatures. Refractories are polycrystalline, polyphase, inorganic, non-metallic, porous, and heterogeneous. They are typically … See more Refractory materials must be chemically and physically stable at high temperatures. Depending on the operating environment, they must be resistant to thermal shock, be chemically inert, and/or have specific ranges of See more Refractory materials are useful for the following functions: 1. Serving as a thermal barrier between a hot medium and the wall of a containing vessel 2. Withstanding physical stresses and preventing erosion of vessel walls due to the hot medium See more • Fire brick • Masonry oven • Refraction (metallurgy) See more Refractories are classified in multiple ways, based on: 1. Chemical composition 2. Method of manufacture See more All refractories require anchorage systems such as wire formed anchors, formed metal (for example, hexmetal) or ceramic tiles to support the refractory linings. The anchorage used for refractories on roofs and vertical walls are more critical as they must remain able to … See more WebMay 1, 1991 · Basic Refractory Design Uninsulated refractory sidewalls generally yield a furnace shell temperature of about 65OF for a new lining. Comparatively, new linings with common thicknesses of insulation show sidewall shell temperatures ranging from 450-550F.
