The GMS Series by MRL features magnesia forsterite bricks made from high-purity magnesia and low-iron forsterite, fired at medium to high temperatures. These bricks offer excellent thermal shock resistance, high-temperature creep resistance, and robust resistance to sulfate and slag corrosion, making them a cost-effective alternative to magnesia chrome bricks in regenerator checkers. Due to the natural resource limitations of forsterite, the product quality may vary significantly among suppliers. However, MRL ensures stable performance and structural integrity by leveraging its over 60 years of experience in checker brick manufacturing. The GMS series is typically used in the middle-lower zones of regenerators, striking a balance between durability and economic efficiency.
