Profile Of Magnesia Brick
Date:2015-08-21 19:13 From:Zhengzhou Sunrise Refractory Author:admin
Magnesia brick is an alkali refractory whose main crystal phase is periclase, and the content of MgO is more than 90%. Magnesia brick is made by sintering in high temperature which is through crushing, batching, mixing, molding and sintering at high temperature of 1550 ~ 1600 degrees.
Magnesia brick is the main product of alkali refractories with the good property of slag resistance, superior refractoriness under load, good alkali resistance, strong corrosion resistance and steady volume in high temperature.
With the above excellent characteristics, magnesia brick can be mainly applied to basic open hearth furnace, steel-making furnace bottom and furnace wall, non-ferrous metal smelting furnace and high temperature tunnel kiln, especially in glass industry, magnesia brick can be used in the regenerators of glass furnace.
Zhengzhou Sunrise Refractory Co., Ltd. who is a professional glass refractory manufacturer is mainly engaged in the research and development of glass refractory products.
