Direct-Bonded Magnesia-Chrome Bricks and Semi direct -bonded Magnesia-Chrome bricks Direct are composed of high-purity or secondary-purity or fused magnesia and chrome concentrate.
Glass phase concentrate in the triangle zone of the crystalline phases. Which are directly bonded to each other.
The produces are characterized by low-porosity. high cold crushing strength. Strong resistance to abrasion, corrosion, thermal shock and spilling.
Direct-bonded magnesia chrome bricks are made from high grade magnesite clinker and chrome oxide. By high pressure shaping and high temperature firing, its characteristic is the high direct-bonding rate, and big crystallite. It has a good thermal spalling resistance. The low basic neutral nature gives itself a good slag resistance when servicing low acid feed furnaces. The brick is a realistic lining material for refining furnace, electric furnace, glass melting furnace and cement rotary kiln etc. Magnesia chrome bricks are refractory bricks made of a mixture of magnesia (MgO) and chromium oxide (Cr2O3). They are known for their high refractoriness (the ability to withstand high temperatures), excellent thermal shock resistance, and good chemical stability. Features: High refractoriness: can withstand temperatures up to 1750 �°C Excellent thermal shock resistance: can withstand rapid temperature changes without cracking or breaking Good chemical stability: resistant to attack from most acids and alkalis High strength: strong enough to withstand heavy loads and wear and tear Good insulation properties: help to maintain consistent temperatures in high-temperature environments
Supplier: Various firebrick, such as direct bonded magnesia-chrome brick, sic mullite wear-resistant brick, high strength alkali-resistant brick, high alumina brick
Magnesia Bricks Description Magnesia Bricks are alkaline refractory materials. These products have over 90% magnesium oxide content and adopt periclase as the principal crystalline phase. Magnesia Bricks can be divided into two categories of Burnt Magnesia Bricks and Chemical Bonded Magnesite Brick. They have excellent performance of superior high temperature mechanical strength and volume stability. Magnesia Bricks can service in the high temperature of 1750.. They are ideal products for glass furnace application. Magnesia Bricks Features: It is a kind of alkaline refractory product with periclase as main phase magnesite-alumina spinel clinker as basic material. the product has such characteristics as good temperature vibration, good strength and volume stability in high temperature. Magnesia Bricks Application Basic open-hearth furnace for steelmaking Electric furnace bottom and wall Permanent lining of oxygen converter Non-ferrous metal metallurgy furnace Hyperthermia tunnel kiln Lining of rotary cement kiln Heating furnace bottom and wall Regenerative chamber of glass furnace Magnesia Bricks Properties High Refractoriness Good alkaline slag erosion resistance High apparent initial softening temperature Good thermal conductivity High thermal expansion Magnesia Bricks Manufacturing Process Burnt Magnesia Bricks are manufactured with magnesite clinker as the raw material and fired in the high temperature of 1550~1600 after smashing, burdening, mulling and molding. High-purity products can be fired in the temperature that over 1750. Chemical bonded magnesite brick is produced with certain chemical bonding through mixing, molding and drying.
