Customized Size High Temperature Magnesia Carbon Refractory Bricks for Steel Industry

High temperature magnesia carbon/ magnesium carbon refractory bricks for steel industry

Magnesia-carbon bricks are made of high melting point alkaline oxide magnesia (melting point 2800°C) and high melting point carbon materials that are difficult to be infiltrated by slag as raw materials, and various non-oxide additives are added. A non-charcoal composite refractory material combined with a carbon binder.
As a composite refractory material, magnesia-carbon brick effectively utilizes the strong slag erosion resistance of magnesia and the high thermal conductivity and low expansion of carbon, which compensates for the biggest disadvantage of poor spalling resistance of magnesia.
Its main features are: good high temperature resistance, strong slag resistance, good thermal shock resistance, and low high temperature creep.

Preparation Process

Traditional magnesia-carbon bricks made with synthetic tar binders according to the cold mixing process harden and acquire the necessary strength during tar damage, thus forming isotropic glassy carbon. This carbon exhibits no thermoplasticity, which in time relieves substantial stress during liner baking or handling. The magnesia-carbon brick produced with pitch binder has high high temperature plasticity due to the formation of anisotropic graphitized coke structure during the carbonization of pitch.

Magnesia-carbon bricks are mainly used for the lining of converters, AC electric arc furnaces, DC electric arc furnaces, and the slag line of ladle.
