For the safety linings of basic oxygen furnaces, baked magnesite bricks are commonly used. Kümaş designs the most suitable refractory positions for the steel construction of the Basic Oxygen Furnace in collaboration with its design office. This allows the safety linings, typically used in the bottom and trunnion areas, to be reused multiple times. Kümaş produces and develops safety lining bricks with its PY-P YK series, offering various positions and qualities suitable for different purposes and projects.
