Recent investigation of refining furnace lining

In the case of smelting low carbon steel, ultra-low carbon steel and killed steel, the commonly used magnesia chrome brick, alumina magnesia carbon brick, magnesia dolomite brick, castable and commonly magnesia carbon brick cannot meet the requirements of steel quality improvement and smelting speed. Therefore, according to the requirements of steel refining and smelting conditions,…

Low carbonization of steelmaking electric furnace refractories

Due to the development of clean steel and ultra-low carbon steel and the requirements for energy saving and consumption reduction,the development of low carbon refractories has become an inevitable trend.at present,the main development trend of carbon containing refractories used in various parts of electric arc furnaces,such as magnesia carbon bricks,aluminum carbonaceous materials,Al2O3-MgO-C materials or other…

Development and application of refractory materials for steelmaking electric furnace

Lightweight With the improvement of energy conservation and environmental protection requirements,the lightweight of kiln has become and inevitable trend of development.the development of low thermal conductivity and energy-saving refractories is mainly reflected in the following aspects: Design of material structure using lightweight aggregate:light weight is achieved under the premise of ensuring the necessary corrosion resistance…

The carbon in the magnesia carbon brick

The role of carbon in refractories Applications in refractories are not uncommon, and many new products have been developed in the past year to accommodate new metallurgical processes and developments in refractories.Refractory experts have long known that different forms of carbon exhibit excellent properties in refractories.In refractory oxide, carbon can reduce the wettability of slag,…
