Top Quality Custom Made Magnesia Carbon Brick for Steel Furnace

Brief introduction of magnesia carbon brick

So far, in the iron and steel metallurgical industry is still a large number of magnesia carbon brick, magnesia carbon brick application improved the converter of various technical wood economic indicators, reduce the consumption of refractory materials. In addition, as a non-burning products, compared with the traditional firing magnesia dolomite bricks, magnesia carbon bricks production of fuel consumption savings of at least 80%.

Application of magnesia carbon brick

  1. Furnace mouth: because the temperature of furnace mouth changes violently and the erosion of slag and high temperature waste gas is more harmful, the refractory used for furnace mouth must have high thermal shock resistance and slag resistance
  2. Furnace cap: furnace cap is a part seriously corroded by slag, so magnesia carbon bricks with strong slag resistance and thermal shock resistance are required.
  3. Furnace hearth and bottom: these parts are severely scoured by molten steel during blowing, but the damage is generally light compared with other parts, so magnesia carbon bricks with low carbon content can be selected.
