Magnesia Alumina Spinel Brick

Magnesia Alumina Spinel Brick for Sale

Description

Magnesia Alumina spinel brick is a kind of high-temperature refractory material with excellent performance of high-temperature resistance and erosion resistance, which is widely used in high-temperature industrial fields such as iron and steel smelting, cement manufacturing and glass melting.
Magnesia-aluminum spinel bricks have the advantage of good thermal stability. During the process of use, it will react with clinker and then form a thin protective layer of calcium aluminate on the outside of the brick.

Features

High temperature resistance

High strength at high temperatures: at high temperatures, magnesium-aluminum spinel bricks have good strength and stability, and are able to resist external high-temperature corrosion and erosion.

Excellent thermal shock resistance

Magnesia Alumina spinel bricks can withstand rapid temperature changes without cracking or fracturing, so they are ideal for applications with frequent temperature fluctuations.

High strength and abrasion resistance

Magnesia Alumina bricks have high density and strength, and are highly resistant to mechanical abrasion.

Resistance to acid erosion

Magnesia-aluminum spinel bricks are able to resist the erosion of acidic substances, enabling them to operate stably in acidic media at high temperatures.

Resistant to alkali erosion

Magnesium-aluminum spinel bricks are also able to resist the erosion of alkaline substances, making it possible to operate normally in high-temperature alkaline media.

High chemical stability

With strong resistance to acid, alkali and oxidation, it has high chemical stability in different media.

Application

Iron and steel smelting

In the process of iron and steel smelting, magnesium-aluminum spinel bricks have a wide range of applications, and can be used in different parts of the furnace, furnace throat, cooling wall and so on. Among them, the most common application is in the body and roof of the steel converter to ensure the safe and stable operation of the steel production process under the high temperature environment.

Cement manufacturing

In the cement manufacturing process, magnesium-aluminum spinel bricks can be used in different equipment such as rotary kiln, preheater, cooler, etc. to ensure the reliability and stability of its long-time operation under high-temperature conditions.

Glass melting

In the process of glass melting, magnesium-aluminum spinel bricks can be used in the melting kiln and its supporting equipment, the bottom pool and other parts to ensure the quality of glass melting and production efficiency.
