Product Information
Magnesia Iron Spinel Bricks are a type of refractory brick made by combining magnesia and iron oxide. These bricks are noted for their remarkable strength and high resistance to heat, wear, and corrosion. Furnaces, kilns, and incinerators use them frequently.
The Importance of magnesia iron spinel bricks in the refractory industry lies in their unique properties that make them ideal for use in high-temperature environments. They can withstand temperatures of up to 1750°C, making them a popular choice for use in furnaces and kilns where temperatures can reach extreme levels.
They are also good for use in environments with a lot of chemicals because of their high corrosion resistance. And they have a longer lifespan than other refractory materials, which reduces maintenance costs and downtime.
