BURNT MAGNESIA DOLOMITE BRICK

摘要

PURPOSE:To improve slag permeation resistance, structural spalling resistance, joint melt damage and wear resistance which have not been solved by a conventional technology and to extremely better slaking resistance. CONSTITUTION:100wt.% of a refractory material consisting essentially of magnesia and dolomite is blended with 1.0-5.0wt.% of titania fine powder having <=200mum. Thickness of slag permeation is reduced by 32.5% in practical use. As the result of the reduction, drop in 5.9% melt rate is recognized and stag permeation resistance can greatly be improved. Extreme effects on structural spalling resistance and corrosion resistance are obtained by the improvement.
