Dingsheng mining professional light burned magnesia powder manufacturer, refractory materials have high purity.

The raw materials of refractories have high purity:

(1) the composition of molten iron has a significant effect on the life of lining refractory, especially the content of silicon, phosphorus and sulphur.

(2) the high end temperature of the converter will lead to the reduction of the lining life, especially when the end temperature is above 1700 degrees C, and the corrosion rate of the lining refractories will be significantly increased by each increase of 10 degrees C.

(3) increasing the basicity of slag is beneficial to reduce the erosion of slag to basic refractories.

(4) increasing the MgO content in slag can reduce the erosion of slag to refractory materials.

(5) increasing the FeO content in slag will cause corrosion of refractory lining.

(6) in the early stage of converter blowing, the basicity of slag is relatively low and the erosion of lining is serious. Dolomite slagging should be used to make the MgO content in slag close to saturation.

(7) fluorite also eroded the lining. Therefore, the amount of fluorite should be reduced as far as possible.

(8) in dolomite and magnesia dolomite refractory, the slag resistance of MgO is better than that of CaO, but the presence of CaO can improve the thermal plasticity and slag penetration resistance of the refractories.

(9) the material required for furnace lining refractories has a high purity, such as magnesium dolomite sand required for the total amount of impurity SiO2+A12O3+FeO less than 3%, and other similar requirements such as fused magnesia, graphite and so on.

Light burned magnesia

 

Magnesium Oxide recognized Dingsheng Mining: Magnesium Oxide, desulfurization of Magnesium Oxide, professional light burned magnesia powder manufacturers. Relying on the abundant magnesite resources in Dashiqiao, the Magnesium Oxide products produced by our factory have good activity, high purity, positive color and very stable quality. Light burned magnesia ball has the characteristics of high magnesium content, low silica content, low surface rate, fast delivery speed, strong production capacity and large monthly output.

With the continuous development of the economy and the continuous progress of science and technology, Magnesium Oxide, light burned magnesia balls and magnesia products have been widely applied. Magnesia powder has been widely used in the fields of metallurgy, steelmaking, chemical, chemical, feed, environmental desulfurization, medicine, chemical fertilizer, construction, railway and so on. Magnesium Oxide recognized the fire resistance of Higa. Magnesium Oxide for magnesium, desulphurization and professional Magnesium Oxide
