Chrome Zirconia Corundum Brick

Chrome Zirconia Corundum Brick for Sale

FLM-15 chrome-zirconia corundum brick is a high quality refractory developed by Fireramo. Fireramo’s chrome-zirconia corundum brick combines the superior properties of chromium oxide, zirconium oxide and alumina to provide excellent resistance to high temperatures, abrasion, and chemical attack.

Fireramo strictly controls the composition of chrome zirconia corundum bricks to ensure that the content of chromium oxide (CrO₂) is ≥15% and zirconium oxide (ZrO₂) is ≥3%, while guaranteeing that the content of high-purity alumina (Al₂O₃) is ≥80%, and restricting the content of silica (SiO₂) to ≤2%.

Fireramo chrome zirconium corundum bricks characteristics

Excellent refractory performance: FLM-15 chrome zirconium corundum bricks can still maintain good load refractive index in high temperature environments above 1700℃, which ensures its long-term stable work under extreme conditions.

High density and low porosity: Fireramo chrome zirconium corundum bricks have a bulk density of ≥2.35 g/cm³, meaning that the bricks have a compact structure and an apparent porosity of ≤18%. This greatly reduces the energy loss during heat transfer and enhances its thermal insulation and overall strength.

High Strength and Wear Resistance: FLM-15 chrome zirconium corundum bricks are precision processed and sintered at high temperatures, with a cold compression strength of ≥80 MPa. FLM-15 chrome zirconium corundum bricks are excellent in carrying heavy loads and resisting mechanical shocks, and are especially suited for use in abrasion-resistant and heat-shock-resistant environments.

Corrosion and oxidation resistance: Thanks to a certain proportion of chromium and zirconium, FLM-15 chrome-zirconium corundum bricks have excellent resistance to acid and alkali attack and oxidation, which prolongs their service life.

Applications of Fireramo chrome zirconium corundum bricks

FLM-15 chrome-zirconium corundum bricks are widely used in metallurgy, petrochemicals, ceramics, glass and other industries in a variety of high-temperature equipment and furnaces, such as steelmaking electric arc furnace, refining furnace, non-ferrous metal smelting furnace, chemical gasification furnace lining masonry, as well as the key parts that require high strength, high abrasion resistance and good thermal shock resistance.
