Shangzhuang Refractories Co., Ltd., Zhengzhou City, to introduce basic refractories magnesium oxide, calcium oxide as the main component of refractories, the main products are brick, magnesite-chrome brick, brick, magnesium, zirconium, magnesium aluminate spinel brick ,, Mg-Al brick, brick, magnesium, calcium, dolomite brick and newly developed iron magnesium spinel brick. Containing magnesium oxide (Mgo) more than 80% of the firebrick called brick, according to the index can be divided into many grades of refractory grade wholesale, brick alkaline slag and iron slag has good resistance Which refractories, refractory degree higher than the clay and brick. Mainly used on open hearth, basic oxygen furnace, furnace, non-ferrous metal smelting equipment and glass industries as well as some of the high-temperature equipment. Magnesia-chrome brick for more basic slag resistance and thermal shock resistance is also much higher than brick, so the more widely, magnesia-chrome brick in steel smelting and non-ferrous metallurgy industry has almost replace brick . Refractories Co., Ltd., Zhengzhou City shangzhuang understand refractory raw materials rich in natural resources in Henan, except magnesia raw materials, other raw variety, good quality. Henan bauxite reserves amounted to 280 million t, ranking second in the country. In addition, Henan coal, electricity and other energy sufficient refractories manufacturers, based on a variety of materials fused, synthesis, sintering, homogenization and other materials in the domestic market accounted for a large share, and exported to Europe, America and Southeast Asian countries enjoyed a high reputation. But raw mining method behind wasteful mining, mining the rich abandoning the poor, less than 50% recovery of ore mined, serious waste of resources.
