내화벽돌Refractory Brick
SD Tech's refractory bricks are generally categorized into high-alumina bricks (SK36, 37, 38), which use high-purity alumina raw materials, and bricks made from fireclay and chamotte (SK34).
These products are manufactured through particle size adjustment, high-pressure molding, and high-temperature sintering of high-quality raw materials, and are in highly diverse demand.
