Magnesia Bricks
Basic Refractory Bricks for High-Temperature Industrial Furnaces

Magnesia Bricks Manufacturer & Exporter in India

At Oryvia Refractories, we offer refractory solutions for demanding high-temperature industrial environments. Our Magnesia Bricks are basic refractory products primarily composed of magnesium oxide (MgO), designed for suitable furnace and kiln lining applications where resistance to basic slags and high-temperature operating conditions is important.

Magnesia refractory bricks are widely used in metallurgical and other industrial thermal processing operations. Their material characteristics make them relevant to steelmaking furnaces, cement rotary kilns, non-ferrous metal processing furnaces and other suitable high-temperature equipment. We work with industrial buyers to understand their application requirements and identify appropriate refractory product specifications.

Frequently Asked Questions

  • What are Magnesia Bricks?
    Magnesia Bricks are basic refractory bricks primarily composed of magnesium oxide (MgO). We offer this product category for suitable high-temperature industrial applications where basic refractory characteristics and compatibility with basic slags are important.
  • What are the main applications of Magnesia Bricks?
    Magnesia Bricks are commonly used in selected steelmaking furnaces, electric arc furnaces, cement rotary kilns, non-ferrous metal processing furnaces and other suitable industrial thermal equipment. The correct application depends on the brick grade, furnace design and operating conditions.
  • What is the main chemical composition of Magnesia Bricks?
    Magnesium oxide (MgO) is the principal constituent of Magnesia Bricks. Other chemical constituents and impurities vary according to the selected grade and raw material composition. Contact our team to discuss the required MgO percentage and applicable chemical specifications.
  • How do I select the right grade of Magnesia Bricks?
    Grade selection depends on several factors, including MgO content, impurity levels, slag chemistry, operating temperature, bulk density, apparent porosity, cold crushing strength and refractoriness under load. We recommend sharing your furnace application and technical requirements with our team before selecting a grade.
  • Are Magnesia Bricks suitable for steelmaking furnaces?
    Yes, suitable grades of Magnesia Bricks are used in various steelmaking furnace applications because of their basic refractory characteristics and resistance to compatible basic slag environments. The correct grade depends on the furnace section, operating conditions and lining requirements.
  • What technical specifications should I check before purchasing Magnesia Bricks?
    Important specifications include MgO content, CaO and SiO₂ levels, bulk density, apparent porosity, cold crushing strength and refractoriness under load. We recommend comparing the complete grade-wise technical data rather than selecting bricks based only on MgO percentage.
  • What information is required to request a quotation for Magnesia Bricks?
    To discuss a quotation with us, please share your required grade or MgO percentage, brick dimensions, order quantity, intended industrial application and operating conditions. Technical drawings or existing refractory specifications can also help us understand your requirements.
  • What is the difference between Magnesia Bricks and Magnesia Chrome Bricks?
    Magnesia Bricks are primarily MgO-based basic refractory products, whereas Magnesia Chrome Bricks contain both magnesium oxide and chromium oxide (Cr₂O₃) as important constituents. Their chemical composition, properties and suitable applications differ. The selection should depend on slag chemistry, operating conditions and environmental requirements.
