High chromium bricks

Refractory high chromium bricks are made of corundum and molten chromium oxide as the main raw materials, plus fine Powder and other additives, kneaded. Drying at high temperature in shuttle kiln, high chromium brick has good thermal stability and high temperature creep performance. High chromium bricks are made of industrial grade chromium trioxide and alumina as the main raw materials, or introduce a small amount of zirconia, etc., after high temperature firing, the content of chromium trioxide is not less than 75%, chromium trioxide, alumina and Shaped refractory products with a total content of zirconia not less than 98%. It hasexcellent corrosion resistance, high compressive strength at room temperature, high strength at high temperature, excellent wear resistance, high refractoriness, excellent thermal shock resistance, and good volume stability at high temperatures.

Product Presentation

Features of isostatic chrome brick
(1) Excellent resistance to slag erosion.
The Cr2O3 material itself has excellent resistance to slag erosion, which is mainly due to the following points: 1) The solubility of Cr2O3 in coal slag is very low, thus ensuring the integrity of the material; 2) Most of the slag has an effect on Cr2O3 materials. The wettability is poor, thereby delaying the dissolution of Cr2O3 in the slag; 3) The dissolution of Cr2O3 material in the slag will increase the viscosity of the slag, and even form a uniform protective layer on the surface of the material to block the pores of the material and inhibit Slag penetration.
(2) Excellent high temperature performance.
The main components of high chromium bricks, Cr2O3, Al2O3, and ZrO2, have melting points of approximately 2400, 2050, and 2700℃, respectively. After 1700t high temperature treatment, Cr2O3 and Al2O3 form a well-crystallized and continuous aluminum-chromium solid solution, so high-chromium refractory The material has high high temperature strength.
(3) Excellent anti-erosion performance.
The formation of aluminum chromium solid solution and the sintering effect of ZiO2 make high chrome materials have lower apparent porosity and higher compressive strength (up to 150 MPa or even more than 200 MPa), so high chromerefractories have good resistance Scouring performance.
(4) Thermal shock resistance and thermal peeling resistance.
Due to the phase change toughening effect of ZrO2, the thermal shock resistance and thermal exfoliation resistance of high chrome refractories are improved.

Application Scenarios

High chrome brick is used in the production of chemical plants, chemical kilns, and alkali-free glass fiber kilns. The key part of waste incinerators and glass furnace.

High chrome bricks used in Glass industryz

Using higher grade refractory materials like high chrome brick in key part is an effective way to increase the overall service life of the Resistance to alkali and glass liquid erosion of Chrome bricks is better than that of AZS, it can replace AZS block in the key part, like corner brick of the dog house, barrier, bubbling area, cover brick and throat etc. ......to gain a better performance.

Orther industry

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.
