1800 Degree High Temperature Kilns Magnesia Chrome Brick
Directly Combined Pre-assemble magnesia Chrome Brick Magnesite Refractory Bricks for RH furnace
Product Description
Basic refractory magnesium oxide content of magnesia brick in more than 90%, the main crystalline phase to pericase. Magnesia brick have high refractoriness,alkali slag good performance, high load softening temperature, but poor thermal shock resistance.
Purity and firing temperature high magnesia brick , due to direct contact with periclase grains, known as a direct bonded magnesia brick , fused magnesite as raw material made of brick that fused rebonding magnesia brick.
