Impact of Different Additives on Performances of Unfired Magnesia-Calcia Brick for AOD Furnace

Abstract:

This paper studied the impact of different additives and their amount on the performances of unfired magnesia-calcia brick by detecting cold crushing strength, volume concentration, after-firing linear change, slag resistance and microstructure. The results showed that samples with Zirconia or Zircon had relatively high cold crushing strength. The sample with 4% TiO₂ had the maximum volume concentration after firing. With the increase in the amount of additives, contraction occurred to all the samples, in which samples with Zircon had the smallest linear change and the most stable volume. Samples with 4% ZrO₂and Zircon had better slag resistance.
