Product Overview
Magnesia refractory bricks are a type of basic refractory material manufactured using high-purity magnesium oxide as the primary raw material. They feature exceptionally high refractoriness and excellent resistance to erosion by basic slags.
Product Features
These bricks exhibit superior high-temperature performance, high structural strength at elevated temperatures, and strong resistance to alkaline corrosion, making them suitable for use in highly alkaline environments. Additionally, they possess excellent thermal stability and offer a long service life.
Key Application Areas
Magnesia refractory bricks are widely utilized in high-temperature equipment such as steel smelting furnaces, electric arc furnaces, converters, and cement rotary kilns.
Primary Application Zones
They are primarily employed in the working linings of furnaces and in zones subject to severe high-temperature erosion.
