Fused Magnesite (Ordinary Grade)
Magnesia Carbon Refractory Brick for Steel Mill (Ordinary Grade) is manufactured through fusing high quality raw magnesite in electric arc furnace with the characteristics of big crystal, dense structure and strong corrosion resistance. As an excellent basic refractory raw material, its MgO content is between 87 – 98%.
Fused Magnesite (Big Crystal)
Magnesia Carbon Refractory Brick (Big Crystal) is manufactured through fusing high quality calcined magnesite at high temperature in electric arc furnace with the characteristics of complete crystal, dense texture, good high temperature performance and strong corrosion resistance.
Magnesia Carbon Refractory Brick (Big Crystal) whose MgO content is between 97 – 99% is widely used in refractory industry. Meanwhile, it is also an excellent high-temperature endurable insulating material.
