Runner Brick

Description of Runner Brick

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.
