What is magnesia dolomite refractory?
Magnesite dolomite refractory contains a lot of free CaO, high temperature has a larger plasticity, can buffer the thermal stress due to temperature fluctuations. Thermal shock resistance is better than magnesium chrome brick
Because the magnesia dolomite refractories used in the process or after the use of the waste brick process, does not produce environmental pollution. Based on the above advantages, the development of magnesia dolomite refractories has received widespread attention. However, magnesia dolomite refractories CaO easy to water, a lot of inconvenience to the production, transportation, using magnesia dolomite refractories, which limits the development of magnesia dolomite refractories.
In the firing zone of the cement kiln, the f-CaO in the magnesia dolomite material is easily combined with C2S in the clinker to form C3S, so that the kiln cover is easy to be hung, and the kiln crust and the refractory brick are firmly combined and easy to maintain
The CaO of magnesia dolomite refractory is beneficial to the purification of molten steel. In the aspect of smelting clean steel, magnesia dolomite refractory also has good dephosphorization and desulfurization effect
The magnesite and dolomite is rich in resources, wide distribution and low price.
