Refractory - Wikipedia

A refractory material or refractory is a material that is resistant to decomposition by heat, pressure, or chemical attack, and retains strength and form at high temperatures. Refractories are inorganic, nonmetallic, porous, and heterogeneous. They are typically composed of oxides of the following materials: silicon, aluminum, magnesium, calcium, and zirconium.dolomite waste refractories,Home > Mine > dolomite waste refractories Refractory - Wikipedia, the free encyclopedia A refractory material is one that retains its strength at high temperatures.Recycling Method of Waste Refractory Bricks in,In this case, Recycling Method of Waste Steel refractory brick In the monthly production of 900t steelmaking waste bricks, there are 250t can not be selected points and can only be abandoned,

RHI & Magnesita: how they stack up - IMFORMED

RHI & Magnesita: how they stack up One could argue that last week’s announcement of the proposed merger of two of the world’s largest magnesia and refractory groups – RHI AG’s takeover of Magnesita Refratários SA to form RHI Magnesita – was only a matter of time.Dolomite – Its Processing and Application in Iron,When dolomite is used as a fluxing material then it is used as either raw dolomite or calcined dolomite. When dolomite is used for the protection of refractories, it is used in calcined form and when dolomite is being used as a refractory raw material, it is used in the form of sintered dolomite. The uses and form of dolomite in iron and steel,Production of porous firebrick from mixtures of clay and,,Fired sample containing only clay and refractory waste mixture Refractory waste was used to increase the refractoriness of the product by reducing the amount of glassy phase in the structure.
