MgO-C Brick for Ladle
MgO-C Brick for Ladle
With high-quality magnesia and flake graphite as the main raw materials, ladle MgO-C brick is formed by pressing.
It has the characteristics of good slag and molten steel erosion resistance, stable volume, and good thermal shock resistance. It is used for smelting ordinary carbon steel and high-carbon steel.
