Product Details
Product Introduction
Magnesium dolomite bricks are primarily made from dolomite, incorporating a significant amount of calcium oxide (CaO) and magnesium oxide (MgO). Classified as alkaline refractory materials, their composition typically consists of 40% to 60% CaO and 30% to 40% MgO. These bricks boast superior high-temperature resistance and exceptional durability against alkaline slag erosion, particularly within the linings of Argon Oxygen Decarburization (AOD) furnaces used in the production of stainless steel. Furthermore, magnesia dolomite bricks find extensive applications in high-temperature settings, including refining furnaces and waste incinerators. When compared to conventional magnesia-chrome bricks, these provide enhanced corrosion and spalling resistance. The use of stainless steel refining systems has become prevalent in countries such as the United States, Japan, and across Europe, leading to the gradual substitution of magnesia-chrome bricks with unburned magnesia-calcium carbon bricks and magnesium dolomite bricks. In recent years, the domestic market has experienced rapid development, achieving standards comparable to international products. Significantly, the service life of certain products has even surpassed that of imported bricks, yielding considerable economic and technical advantages. Magnesium dolomite bricks are well-suited for diverse high-temperature and highly corrosive environments, ensuring sustained operational stability, reduced maintenance expenses, and enhanced equipment performance.
Advantages and features
1. Outstanding high temperature durability: The composition of magnesium dolomite bricks, which contains a significant proportion of calcium oxide (CaO, 40%-60%) and magnesium oxide (MgO, 30%-40%), ensures they remain stable even in extreme temperatures. 2. Strong resistance to alkaline slag erosion: With remarkable resistance to alkaline slag erosion, these bricks are particularly ideal for highly corrosive environments, exhibiting excellent durability and prolonging equipment lifespan. 3. Superior anti-stripping capability: Their exceptional performance against stripping at elevated temperatures minimizes the need for frequent maintenance and replacements, thereby lowering operational costs. 4. Modern alternative to traditional refractory materials: In the context of stainless steel production, magnesium dolomite bricks demonstrate superior performance as linings in AOD furnaces, progressively replacing conventional magnesia-chrome bricks with enhanced corrosion resistance. 5. Globally recognized usage: These bricks have seen extensive application in stainless steel refining systems across the United States, Japan, Europe, and beyond, reflecting adherence to international standards.
