Description
Magnesia Bricks Introduction Magnesia refractory bricks are alkaline refractory materials primarily composed of magnesium oxide (MgO) and periclase as the primary crystalline phase. The MgO content is typically over 80%. Magnesia bricks are manufactured by crushing, batching, mixing, and high-pressure forming (usually by mechanical pressing) of sintered magnesia sand. Finally, they are fired in tunnel kilns or downdraft kilns at ultra-high temperatures exceeding 1500-1600°C. With a refractoriness typically exceeding 2000°C, magnesia bricks offer excellent resistance to high temperatures and alkaline environments, making them an indispensable and critical lining material in high-temperature industries such as steel and cement. Magnesia Brick Specifications Rongsheng MGO contents range from 85% to 98% Widely used throughout metallurgical industry

Characteristics of refractory magnesia bricks: 1. High refractoriness: Magnesium oxide has a melting point of up to 2800°C, making the refractoriness of magnesia bricks typically over 2000°C. 2. Excellent alkaline corrosion resistance: Magnesium bricks are extremely resistant to alkaline slag and alkaline dust (such as CaO and FeO). 3. High refractoriness under load: Magnesia bricks exhibit excellent structural stability at high temperatures and are not prone to collapse. 4. High compressive strength: Magnesium bricks have high compressive strength at both room temperature and high temperature, and exhibit excellent mechanical properties.

Product Application
Applications of Refractory Magnesia Bricks Steel Industry: Converter: The primary material for furnace linings, especially in areas susceptible to alkaline slag attack. Electric Furnace: Hot spots on the furnace walls and floor. Ladle: Lining of refining ladles, especially the slag line, used in refining processes such as LF and VOD furnaces. Open Hearth: Back walls and floor. External Refining Furnace: Lining of AOD and RH furnaces. Non-Ferrous Metal Smelting: Furnaces used for smelting metals such as copper, nickel, lead, and zinc, where slag is typically alkaline. Examples include the side and end walls of reverberatory furnaces, flash furnaces, and Noranda furnaces. Cement Industry: Rotary Kilns: Primarily used in the firing zone. This zone experiences the highest temperatures, and cement clinker is highly alkaline, making magnesia bricks a perfect match for these process requirements. Magnesia-chrome bricks are often used (a composite product of magnesia bricks and chromite), but their core strength remains the alkali resistance of magnesium oxide. Glass Industry: Used as regenerator lattices in glass melting furnaces to resist corrosion from high temperatures and alkaline volatiles. Lime Industry: High-temperature linings in vertical and rotary lime kilns.
