Fused Mg-Al Spinel

[Product Specifications]: AM-60, AM-70, AM-80, AM-90

[Production capacity]: 50,000 tons / year

[Scope of application]: It is an ideal material for manufacturing cast slides, nozzle bricks, ladle-friendly bricks, and furnace furnace bricks. It is also a basic raw material for large-scale cement kilns, medium-sized cement kiln transition zones, bricks, refractory castables, and high school kiln furniture. Widely used in steel smelting, cement rotary kiln and glass industry kiln.

【product description】:

The Ruishi fused magnesia-aluminum spinel is made of industrial alumina with a purity of ≥98.5% and light-burned magnesia with a purity of ≥96% and is compounded with an appropriate amount of high-purity magnesite (MgO> 47%). Spinel clinker and AL2O3 spinel solid-melt clinker with 70% and 90% of AL2O3 content, respectively, prepared by high temperature in an electric arc furnace, can be processed into particles, fine powder and micron powder with different particle sizes. Its grains are well developed, dense in texture and uniform in structure. Ruishi fused magnesia-aluminum spinel has the characteristics of high temperature resistance, large body density, low water absorption, small thermal expansion coefficient, good thermal stability, and strong corrosion resistance. Product specifications include: AM60, AM70, AM80, AM90.
