Resin Magnesia Tundish Bricks
Resin magnesia tundish bricks are tundish working layer bricks with high magnesia (over 70%), low carbon (under 30%), and resin bonding for continuous steel casting. They are erosion and corrosion resistant, making them ideal for steelmaking applications. They are classified under tariff item 6810.11.00 as building blocks and bricks of artificial stone.
