Thermal Conductivity Magnesia Carbon Brick , magnesite refractory bricks,High Basic Slag Resistance Refractory Blocks
Product description:
Magnesia-carbon brick is made of high melting point alkaline oxide magnesium oxide (melting point 2800℃) and carbon material with high melting point which is difficult to be infiltrated by slag.A non - burning carbon composite refractory bonded by a carbonaceous binder.Magnesia-carbon brick is mainly used in converter, ac arc furnace, dc arc furnace lining, ladle slag line and other parts.
As a kind of composite refractory, magnesia carbon brick effectively utilizes the slag erosion resistance of magnesia and the high thermal conductivity and low expansibility of carbon, which compensates for the biggest disadvantage of magnesia's poor peeling resistance.
Characteristics :
1. Good high temperature resistance;
2. Strong slag resistance;
3. Good thermal shock resistance;
4. Low creep at high temperature
