High anti-flaking magnesia carbon brick

Study on high resistance to spalling magnesium-carbon brick

Three different formulations and magnesia carbon bricks treated with different heat treatment methods (see table below) were studied. The 1# sample is a low-temperature heat-treated brick composed of fused magnesia, high-purity graphite and phenolic resin, and the 2# sample is a brick which is fired and asphalt-impregnated on the basis of the 1# sample, and 3# is in Add powder bricks in 1#.

Samples 1 2 3
Fused magnesia 80 80 77
graphite 20 20 20
AI powder 3
Phenolic Resin +3 +3 +3
Heat treatment Low temperature heat treatment Firing + asphalt impregnation Low temperature heat treatment
Bulk density 2.9 2.96 2.9
Apparent porosity 3.5 1.2 3.7
Cold crushing strength 44 57 45

As a result, it is considered that the brick (2#) which is not immersed in the aluminum powder and is immersed and fired by the asphalt is better than the other two bricks.
