Refractories Co., Ltd., Zhengzhou City shangzhuang understand refractory wear depends on the composition and structure of the material. When the material is dense polycrystal composed of a single crystal, the wear resistance depends on hardness of the constituent material of mineral crystals. Refractory price high hardness, high wear resistance. As for unusual sexual refractory mineral crystals when fine grain size, high wear resistance. When the material consists of multi-phase composition, its wear resistance is also directly related to the bulk density or porosity of the material, also in connection with the classification of the relevant group. Thus, at room temperature in terms of a particular refractory refractory wholesale, its wear resistance is proportional to its compressive strength, the sintered article of good abrasion resistance is also good. The wear resistance of refractory products related to temperature. Shangzhuang Refractories Co., Ltd., Zhengzhou City, to introduce basic refractories magnesium oxide, calcium oxide as the main component, the main products are brick, magnesite-chrome brick, brick, magnesium, zirconium, magnesium aluminate spinel brick brick ,, magnesium, calcium brick, dolomite brick and iron magnesium spinel newly developed bricks. Containing magnesium oxide (Mgo) more than 80% of the firebrick called brick, according to the index can be divided into many grades grades, brick alkaline slag and iron slag has good resistance, high refractoriness than 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 .
