Pre-laid magnesia carbon (MgO-C) bricks#refractory

Pre-laid magnesia carbon (MgO-C) bricks are used in converters (also known as basic oxygen furnaces or BOFs) in steelmaking. These bricks are pre-assembled and pre-bonded into larger blocks or sections that can be quickly and efficiently installed in the converter lining. This method of lining installation has several advantages, particularly in terms of reducing downtime and improving the efficiency of maintenance operations.
Key Aspects of Pre-Laid Magnesia Carbon Bricks
1.Material Composition
Magnesia (MgO)、Carbon (C)、Additives
2.Pre-Laying Process
Bricks are pre-assembled into larger blocks or modules in a controlled environment before being transported to the steel plant.The bricks are bonded using high-quality refractory mortar or resins, ensuring strong and stable assemblies.The pre-laid blocks are designed to fit precisely into the converter lining, minimizing gaps and ensuring uniform protection.
Applications in Converter Linings
1.Lining the Converter
Hot Spots: Pre-laid MgO-C bricks are often used in high-wear areas, such as the trunnion area, slag line, and around the tap hole.
Sidewalls and Bottom: They are also employed in the sidewalls and bottom lining of the converter, where they provide excellent resistance to wear, corrosion, and thermal shock.
2.Quick Installation
Minimized Downtime: Pre-laid brick modules can be installed quickly, significantly reducing the time required for relining operations. This is crucial in steelmaking, where furnace downtime can be costly.
Efficient Maintenance: Facilitates more efficient and faster maintenance, allowing for quick turnaround times between heats.
