Product Advantages
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%.
Melting Process
Tilting Furnace - Transfert - Cool Down - Barmac Crusher & Sorting - Sand Making - Warehouse
Applications
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.
