"We provide a comprehensive range of refractory bricks for the composition of steel ingot castings. To cater to the specific needs of each steel plant, we have established a wide variety of molds, enabling us to manufacture tailor-made products or special shapes based on distinct production requirements.
The refractory bricks for casting encompass various types, including clay refractory bricks, high alumina refractory bricks, and mullite refractory bricks, available in different shapes and sizes. These primarily include funnel bricks, center bricks, ingot casting bricks, tail bricks, bottom bricks, and plug heads. They exhibit high refractoriness, enabling a substantial steel throughput, along with excellent strength and thermal shock resistance."
