Fused Alumina Magnesia Spinel

Fused Alumina Magnesia Spinel

Fused Alumina Magnesia Spinel is a new type of high-purity synthetic refractory material made from alumina and high-purity light-burned magnesia as the main raw materials in an electric tilting furnace after being melted at a high temperature of more than 2000 ℃ and then cooled.

Features

1. High bulk density

2. Strong erosion resistance

3. High corrosion resistance

4. Good slag resistance and seismic stability

1.The application of advanced electric arc tiliting furnace production increases the smelting temperature and can maintain a constant high temperature production, thereby improving the quality of the aluminum-magnesium spinel.

2. According to the different requirements of customers for magnesium content, various suitable products are produced. Meet customer customization requirements.

3. Using advanced production technology and formula technology, the impurity content in the product is lower.

4. It can improve materials' thermal shock resistance and can be provided with good anti-stripping capacity.

5. It can effectively improve slag resistance and thermal shock resistance of the refractory and unrefractory products.

QC

To the magnesium aluminum spinel, the chemical composition of Al2O3, MgO, SiO2, Fe2O3, CaO Moisture, LOI need to be tested, and the content of Al2O3 and MgO need to be above 98%.

MONOLITHIC REFRACTORIES

An ideal raw material for replacing magnesium-chromium refractory materials. It is widely used in industries such as steel, cement and industrial kilns, such as high-performance alumina magnesia castables.

SHAPED REFRACTORIES

High-grade aluminum-magnesium bricks, liding nozzles, ladle lining bricks, continuous casting skateboards, nozzle bricks and furnace roof bricks, etc.,which can improve the thermal shock resistance of the material and have good Anti-stripping property.
