Brief Description of Magnesia Alumina Spinel Bricks
Magnesia alumina spinel bricks are formed by high-pressure molding and high-temperature sintering. Moreover, magnesia-aluminum spinel can replace magnesia-chromium sand to make magnesium-alumina spinel bricks to avoid chromium pollution. At the same time, we also add specific mineralizers to directly bond between the crystalline particles of the product. So, spinel refractory has good thermal shock stability and it also has good strength and volume stability in high temperature environments. In addition, we can also customize them according to the customer’s usage conditions and specific physical and chemical indicators. Therefore, this ensures the high quality of Kerui magnesium alumina spinel bricks. Welcome to contact us for free customized solutions and quotations.

Uses of Kerui Magnesia Alumina Spinel Bricks
The excellent spinel refractory has good high working temperature and chemical stability, so they are widely used in many industrial fields. Such as the steel industry, petrochemical industry, glass industry, ceramic industry and electric power industry. The following are the specific applications of magnesia spinel bricks in industry.
The spinel bricks can be used in the lining of cac cement rotary kilns. It can withstand good slag resistance and great wear resistance. So, they protect the structure of the rotary kiln and provide good fire resistance. In addition, it ensures the stable operation of equipment under high temperatures.
In the glass industry, magnesia alumina spinel bricks are often used as lining materials for glass melting furnaces. Besides, they are able to withstand high temperatures and chemical attacks. It helps maintain stable temperatures in the furnace and increases glass production efficiency.
Our high performance magnesium alumina spinel bricks are widely used in aluminum electrolytic cells in the aluminum industry. They have good resistance to spalling and corrosion. So, they provide a stable working environment. In other words, it extends the life of the electrolyzer.
We can also use spinel refractory in blast furnaces, converters, electric arc furnaces, cracking furnaces, catalytic cracking units, ammonia synthesis reactors and reforming reactors, etc. If you need spinel refractory or other refractory insulating refractories, you can contact us on Pinterest.
