Selection Of High Alumina Firebrick
High aluminum firebrick is a kind of aluminum silicate refractory with alumina content of more than 48%. It is made of alumina or other raw materials with high alumina content by molding and calcination. High thermal stability, refractories above 1770℃.
First of all, it should be determined according to the specific situation of the kiln. If it is a new kiln, it can be based on the material selection guidance provided by the kiln supplier to understand the use of high-aluminum refractory bricks, the use of temperature, special environment (acid and alkali, high pressure, impact, wear, etc.), and obtain the selection guidance accordingly; If the old kiln maintenance masonry, can be based on the past experience, combined with some effective improvements, the maximum benefit of high-aluminum brick selection scheme.
Secondly, the proportion of standard brick and special-shaped brick is determined. If it is a standard brick, it is easier to purchase, according to the industry or national standards; If it is a special-shaped brick, most of them need to make molds for customized production. The production of shaped bricks, including the accuracy of mold production, is the key to consider the strength of a refractory brick manufacturer.
Finally, find the balance point between the price and quality of high aluminum bricks. Why do you say so? You must have the answer in mind, quality determines production, production determines value. The key to determining the price of high aluminum bricks is the manufacturing process and aluminum content. Aluminum content can be considered by the data, more intuitive, the price of high aluminum bricks on the market is basically measured by the amount of aluminum content, aluminum content is high and the price is very low procurement, we must be careful whether it is false aluminum content; The manufacturing process is mainly marked brick or special-shaped brick, and whether there are special requirements, which has a great relationship with the manufacturer's process and quality management system, which is also the biggest cost advantage for manufacturers and dealers.
High aluminum brick as an important material to ensure the smooth production of the kiln, if the selected product performance is not up to standard, so the kiln repair cost, I am afraid it is not worth the loss. At present, because of the intensification of competition in the industry, the price of high aluminum bricks in the refractory industry is more transparent, as the saying goes, a point of price is a point of goods, we must keep in mind that the greedy little cheap suffer big losses.
