Magnesia bricks for ladle use sintered magnesite or fused magnesia as main raw materials, being high pressure pressed and sintered in high temperature.

　　Magnesia bricks for ladle have the characteristics as follows:

　　1. High-temperature strength;

　　2. Strong anti-erosion ability;

　　3. High resistance to wear;

　　4. Good thermal shock resistance.

　　As the ladle refractories, magnesia bricks or burnt magnesite bricks are mainly used as permanent linings because of high temperature property and high slag resistance.
