manufacturing process of dolomite used as refractory materials

Dolomite Refractory Dolomite bricks are made up of MgO 25-45%, CaO 35-65%, and other materials. They have high refractoriness, Thermal stability at high temperature and slag resistance. They are more porous, more shrinkage softness and less strong. They can be used up to 2300 o C without load and up to 1650 o C with the load.

Jul 29, 2019 In manufacturing steel by the basic open-hearth furnace and L.D. process the importance of dolomite as refractory material has greatly increased. Dead burned dolomite used as refractory lining in basic open-hearth furnaces and Bessemer converters. Also used as a basic flux in the smelting of iron ore in blast furnace removes alumina and slag. May 20, 2017 Dolomite aggregate is a kind of refractory aggregate which is made of dolomite. It can be made into refractory such as dolomite aggregate concrete. Dolomite is carbonate mineral which takes the form of rhombohedral. The color of dolomite aggregate is usually white. Due to dolomite aggregate properties, dolomite is mainly used in making basic refractory, flux for blast furnace iron

How to process dolomite rock and what is it used for

Mar 18, 2021 Dolomite Refractory Brick. Natural dolomite is calcined into dolomite sand, which is then made into dolomite bricks, with CaO content 40%, MgO content 35%, and a small amount of SiO2, Al2O3, Fe2O3 and other impurities. If the mass ratio of CaO to MgO is less than 1.39, it is called magnesia dolomite brick. Dolomite bricks are mainly used in the burning zone of stainless steel Sep 29, 2021 The Qualified dolomite powder will be packed and used in rubber, glass, building, ceramic, etc. While the unqualified powder will be sent back for re-grinding.

The Dolomite sinter or Dead-burned dolomite is generally used in the refractory industry for the refractory made by firing dolomite, with or without additives, at high temperature to produce dense, well-shrunk particles. This refractory is widely used wherever steel is refined using basic slag and can stand temperatures up to 2.300C. Refractory materials are used in some high-intensity and highly industrial applications, requiring robust protective materials. These applications range from furnaces and kilns to incinerators, and even reactors. Refractories are used to make crucibles and similar uses like moulds for casting glass, metals and for flame retardant and heat deflecting surfaces for even as high temperature as ...
