Applications of Fused Spinel
1.It’s widely used to iron & steel, cement and industrial kilns industries, etc
2.It’s mainly used to produce high grade alumina-magnesia brick, high performance alumina-magnesia castables, sliding nozzle, ladle brick, top brick for open hearth furnace etc.
3.It’s a ideal material to replace magnesia-chrome refractories. In addition, it is used in refractory products, prefabricated parts, and unshaped refractory materials.
Fused Spinel, Alumina-Magnesia Spinel is a highly recommended refractory raw material. Use our high-quality pre-reacted ALUMINA-MAGNESIA SPINEL for developing high purity refractories in both monolithic and brick form.
Our high quality Fused Spinel has high bulk density, great color, strong resistance to corrosion and anti-detonation. It adopts high pure MgO and Chemical Al2O3 to smelt by EAF. Applications include but are not limited to the proof of EAF, basic oxygen furnace, steel ladle, intermediate zone cement rotary kiln, etc.
Packing of Fused Spinel
Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.
ATTs’ Fused Spinel is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
