How to distinguish between magnesia carbon brick and aluminum magnesia carbon brick?
Magnesia carbon bricks are generally used for slag production lines, with magnesium sand and graphite as the main raw materials. Aluminum magnesium carbon bricks are generally used for melt pools and bottom cladding, with bauxite, magnesium sand, and graphite as the main raw materials. Prices vary greatly depending on the grade, ranging from 2-3K/t to 6-8K
Introduction to magnesia carbon brick
Magnesium carbon brick is made from high melting point alkaline oxide magnesium oxide (melting point 2800 ℃) and high melting point carbon material that is difficult to be infiltrated by slag, with various non oxide additives added. Non burning carbon composite refractory material made by combining carbonaceous binders
Characteristics of magnesia carbon brick
Flake graphite has the following characteristics: 1. High temperature resistant graphite has a melting point of 3850 ℃± 50 ℃ and a boiling point of 4250 ℃. Even after ultra-high arc burning, the loss of mass is minimal and the coefficient of linear expansion is also small. The strength of graphite increases with temperature, and at 2000 ℃, the strength of graphite doubles and conductivity increases by 2 times
