What is the difference between magnesia carbon bricks and aluminum magnesia carbon bricks?
Magnesia carbon bricks are generally used for slag lines, with the main raw materials being magnesium sand and graphite. Aluminum magnesium carbon bricks are generally used for melting pools and ladle bottoms, with the main raw materials being bauxite, magnesium sand, and graphite. The prices vary greatly depending on the grade, ranging from 2-3K/t to 6-8K
Introduction to magnesia carbon bricks
Magnesia carbon brick is made of high melting point basic oxide magnesium oxide (melting point 2800 ℃) and high melting point carbon materials that are difficult to be wetted by slag, and various non oxide additives are added. Unburnable carbon composite refractory material formed by combining carbon binder
Characteristics of magnesia carbon bricks
Flake graphite has the following characteristics: 1. The melting point of high-temperature resistant graphite is 3850 ℃± 50 ℃, and the boiling point is 4250 ℃. Even after ultra-high arc ignition, the loss of mass is very small, and the coefficient of linear expansion is also very small. The strength of graphite increases with the increase of temperature, and at 2000 ℃, the strength of graphite increases by two times and conductivity
