High alumina refractory brick is a kind of aluminum silicate refractory material with alumina content above 48%. It is formed and calcined from alumina or other raw materials with high alumina content. High thermal stability, refractoriness above 1770℃. The editor of Henan Jianhua Refractory Materials Co., Ltd. introduces the selection of high-alumina refractory bricks in detail below, for your reference only.


First of all, it depends on the specific situation of the furnace. If it is a newly built kiln, you can learn about the parts of high-alumina refractory bricks used, operating temperature, and special environments (acid-base, high pressure, impact, abrasion, etc.) based on the material selection guidance provided by the kiln supplier. Type guidance; if it is used for repairing and building old kilns, you can use past experience and combine some effective improvements to arrive at the most efficient high-alumina brick selection plan.

Secondly, determine the proportion of standard bricks and special-shaped bricks. If it is a standard brick, it is easier to purchase, just follow the industry or national standards; if it is a special-shaped brick, most of them need to be made of molds for customized production. The production of special-shaped bricks, including the accuracy of mold making, is the key to considering the strength of a refractory brick manufacturer.

Finally, find the balance between the price and quality of high alumina bricks. Why do you say that? You must have the answer in your heart, quality determines production, and production determines value. The key to determining the price of high alumina bricks is the manufacturing process and aluminum content. The aluminum content can be considered by data, which is relatively intuitive. The price of standard high-alumina bricks on the market is basically measured by the amount of aluminum content. For purchases with high aluminum content and low prices, you must be careful about whether it is false aluminum content. ; The manufacturing process is mainly standard bricks or special-shaped bricks, and whether there are special requirements. This has a great relationship with the manufacturer's process and quality management system. This is also the biggest cost advantage for manufacturers and distributors.

High alumina bricks are important materials to ensure the smooth production of kilns. If the performance of the selected products is not up to standard, the cost of shutdown of the kiln may not be worth the loss. At present, due to the intensified industry competition, the price of high alumina bricks is relatively transparent in the refractory industry.

Henan Jianhua Refractory Material Co., Ltd. is a comprehensive refractory enterprise integrating scientific research, experiment, development, production, sales and customers. Founded in 1982, the company has the first branch of clay bricks, the second branch of high alumina bricks, the third branch of magnesia carbon bricks, and Zhengzhou Huaxin Furnace Charge Co., Ltd. The main products are high alumina bricks, clay bricks, magnesia carbon bricks, silica bricks, lightweight insulation bricks, castables, ladle castables, tundish coatings, various unshaped "Jianhua Brand" series refractories, etc.;
