Magnesia Aluminum Spinel for Fire Brick
Fused magnesium aluminum spinel is produced by mixing the industrial alumina with the high-purity caustic-burned magnesia, smelting with high temperature more than 2000 degree centigrade in the electric-arc furnaces. And it can be processed into various sizes of particles according to the clients’ demands. Its grain is well developed with the features of compact texture and uniform structure, and there fore is the high-grade raw material for producing refractory products with high in density and good thermal shock resistance ( spinel and magnesia, etc. ).
Fused magnesium aluminum spinel has the characteristics of high bulk density, high thermal shock resistance, strong corrosion resistance and slag- resistance. It is widely used in iron and steel melting, cement rotary kiln and glass furnace, as the ideal material for manufacturing cast sliding plate, nozzle bricks, ladle bricks and open hearth furnace bricks, as well as the basic material for ecotone bricksof large cement kilns, medium cement kilns, refractory castable materials, and first-class and medium-class kiln furniture.

Our Advantages:
1).Factory founded since 1995
2).one-stop service
3).A grade products with high purity
4).production capacity:1000-1500 metric ton/month
Package:
1).if no special request, we will use normal packing,25kg PVC bag, then 40 bags in a big bag for 1000 Kilograms.
2).if need special packing or marks, please list them in your E-mail. We would like to make the packing as requested.
Payment:
1).Our first choice is T/T. For a large order 40% T/T in advance is earnest money, the rest to be paid in 7-10 days after getting B/L copy. For a small order,100% T/T in advance.
2).Second choice is L/C. We can accept irrevocable L/C at sight. For a large order 40%T/T, 60%L/C. We couldn’t accept L/C for a small order. The best way of payment we advise is T/T, because L/C is very complicated and a lot of extra fee is to give the bank.
3).The others: West Union, Paypal.
