Product Description

Sales of Fire-Resistant Chrome and Corundum Bricks with Customizable CrO Content

Chrome Corundum Bricks:

Chrome corundum brick mainly refers to the corundum refractory product containing Cr2O3. Using α-Al2O3 as main raw material,adding appropriate amount of chromium oxide powder and chromium corundum clinker fine powder, after forming process, the bricks
will be sintered at high temperature. At high temperatures, Cr2O3 and Al2O3 form a continuous solid solution, so the high temperature performance of chromium corundum products is better than pure corundum products. In the most widely used chromium
corundum products, the content of Cr2O3 is mostly in the range of 9%~15%. The main mineral composition is α-Al2O3-Cr2O3 solid solution. The secondary mineral composition is a small amount of composite spinel (or no composite spinel). The chromium oxide
content in the chrome refractory brick is from 1% to 30%. There are two types: fused cast chromium corundum bricks and sintered chromium corundum bricks.

Project case of high chrome bricks

With excellent performance and corrosion Resistance , high chrome bricks is widely used together with AZS bricks in the glass kilns, here it is used for glass furnace throat.

Product Presentation

Features of Chrome Corundum Bricks

High Temperature Resistance
Chrome corundum brick can withstand extremely high temperatures, usually above 1700 degrees Celsius can still maintain structural stability.

Good Thermal Shock Stability
Under rapidly changing temperature conditions, chrome corundum brick is not easy to crack and damage, and has good thermal shock stability.

Corrosion Resistance
It has strong erosion ability for acidic and alkaline gases and liquids, and is suitable for corrosive occasions in chemical
industry, metallurgy and other environments.

High Strength
High mechanical strength and compressive ability, can withstand a certain amount of mechanical impact and load.

Application Scenarios

Industry Furnace

Steel Industry: It is used in metallurgical furnaces, electric furnaces, open hearth furnaces with the most severe slag corrosion location, for example, the AOD furnace air eye area of the external refining device, RH furnace vacuum chamber lower groove and impregnation tube, VOD slag Line, etc.

Non-Ferrous Metals: This refractory block is used for non ferrous metallurgical (copper,lead, tin, nickel, etc.) , like converter air outlet area, flash furnace reaction tower, sedimentation tank, anode slag line position, alkaline refractory material kiln high-temperature zone, etc.

Chemical Industry: High-chrome bricks are used in various high-temperature chemical reactors, including those for ammonia synthesis, synthetic rubber production, coal chemical processing,and other chemical processes. They are primarily used in the ammonia synthesis towers, heat exchangers, pipelines in ammonia synthesis plants, reactors, separators, and pipelines in synthetic rubber plants, and so on.

Power Industry: High-chrome bricks are used in waste incineration furnaces and other high-temperature reactors in the power industry.
