Refractory - Wikipedia
Refractory materials are classified into three types based on fusion temperature (melting point). Normal refractories have a fusion temperature of 1580–1780 °C (e.g. Fire clay) High refractories have a fusion temperature of 1780–2000 °C (e.g. Chromite) Super refractories have a fusion temperature of > … Zobraziť viac 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 Zobraziť viac 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, … Zobraziť viac Refractories are classified in multiple ways, based on: 1. Chemical composition 2. Method of manufacture 3. Fusion temperature 4. Refractoriness Zobraziť viac • Fire brick • Masonry oven • Refraction (metallurgy) Zobraziť viac 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 Zobraziť viac 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 … Zobraziť viac WebA popular insulating castables. 2500 ° F Insulating Offers exceptional strengths with low densities and thus high insulating. 55LB/25KG BAGS.
