Runner bricks are special refractory materials used in casting and metallurgical processes. They are made of high-grade refractory materials such as alumina or zirconia.
We can provide a full range of pouring bricks for ingot casting. In order to meet the specific requirements of each steel plant, we have established a variety of molds, so we are able to produce customized products or special shapes according to different production requirements.

1. High heat resistance 2. Excellent corrosion resistance 3. Good chemical stability 4. High mechanical strength
Runner bricks are crucial in foundries and steel production. In foundries, they guide molten metal to molds, ensuring accurate casting. In steel mills, they’re used in continuous casting lines, withstanding high – temp steel to enable smooth, efficient production.
