Product Features:

The brick is made in presure from dead burned magnesia (or fused magnesia) and carbon material (full-crystal graphite) with the binder of pitch and resin. Magnesia-carbon brick at high temperature forms combination of carbon frame. Magnesia and carbon can't be fused each other. So it keeps their properties good . In addition, carbon has a better thermal conductivity. Both of high expansion and spring coefficients are low. It can effectly resist to thermal flaking, slag corrosion and constructure flaking. Carbon has no wettability to slay, so resistance to corrosion is good. The brick is widely applicated in steel electric arc, combined blowing converter, ladle, torpedo, refined ladle furnace,  ect.
