Magnesia Carbon Brick Magnesia Carbon Brick Introduction Changxing Refractory is able to manufacture magnesia carbon brick for every ladle, EAF, and BOF. We will design you a well-balanced lining, providing optimal performance at the lowest possible cost. Our magnesia-carbon brick is made from more than 98% electrically fused magnesite, high purity graphite and metallic antioxidants as needed. Size and specification can be tailored according to furnace type. Changxing Refractory magnesia carbon refractory brick factory is located in the magnesium capital of China, and products with high bulk density and low porosity. Magnesia Carbon Bricks Manufacturers series used for the electric furnace are made by adoption of fused magnetite, high-purity magnesium sand and graphite as principal raw material, through high-pressure molding and low-temperature treatment. This product is mainly used for electric furnace lining, which enjoys advantages including high temperature resistance s...

Application of low thermal conductivity MgO-C bricks in ladle

图片
Magnesia Carbon Brick Currently, inhibition of steel temperature droping has become a major issue for many steel plants. Therefore, in order to suppress temperature drop of molten steel, there has a test to study insulation problem of refractory material lining in 185t ladle, by comparing three different measures. Measure 1: Reducing the heat transfer effect of sidewall castables (30% reduction). This method is by reducing coarse particles in castable, increasing porosity and other measures to reduce the thermal conductivity, to suppress heat dissipation. Measure 2: Using insulation materials in the backlayer of wall castable. This method is to use one layer insulating refractory bricks with less than 1W (m celsius) thermal conductivity between ladle steel shell and wall castable, to inhibit heat dissipationheat. Measure 3: Reducing the heat transfer of slag line magnesia carbon brick heat transfer (30% reduction). This method is developed in recent years, to select ...

Application range of magnesia carbon bricks

Application range of magnesia carbon bricks Application range of magnesia carbon bricks Magnesia carbon bricks  are made of magnesia, dead-burned magnesia, fused magnesia, high-purity magnesia, high-quality graphite and bauxite additives. The performance of alumina magnesia carbon bricks has a great relationship with the graphite content in the bricks. As the graphite content increases, the strength of the brick decreases, the thermal expansion rate decreases, and the residual expansion rate increases. Refractory  MgO-C bricks  are very suitable for the requirements of steel smeltin. This kind of brick has the characteristics of high fire resistance, high corrosion resistance, excellent heat resistance, high temperature spalling stability, high thermal shock resistance, etc. It has been rapidly popularized and applied. Using carbon materials that are difficult to be wetted by slag, molten steel, and the high refractory properties of magnesia, high slag resistance and solu...
