Steam boiler refractory bricks we recommend high alumina refractory bricks, high alumina refractory bricks are one of the common refractory materials for kilns, often mixed with high alumina refractory castable, with high-temperature resistance, 耐摩耗性, 耐熱衝撃性, and other characteristics.
蒸気ボイラー用耐火レンガの入手場所?
The high alumina bricks produced by our company are scientifically controlled by advanced equipment, and the quality is excellent.
The high alumina brick produced and sold by our company is a kind of aluminous silicate refractory material with an alumina content above 48%. ボーキサイトなどのアルミナ含有量の高い原料を成形、焼成して作られます。.
高い熱安定性, refractories above 1770℃.
Good resistance to slag. いつもの, the green aluminum content is divided into three grades, the higher the aluminum content of high alumina bricks the higher the performance.
Mainly used for masonry blast furnaces, 熱風炉, 電気炉の屋根, 高炉, 反射炉, ロータリーキルライニング. 加えて, high alumina bricks are also widely used as lattice bricks for storage of heat in flat furnaces, 注湯システム用プラグヘッド, 吐水口レンガ, 等々.
でも, の price of high alumina brick is higher than clay brick, so it is not necessary to use high alumina brick where clay brick can meet the requirements.
High alumina brick and more clinker clay brick production process are similar, the difference is that the proportion of clinker in the ingredients is high, can be as high as 90 〜 95%, clinker in the crushing before the need for classification picking and sieving iron removal, firing temperature is higher. Such as Ⅰ, Ⅱ and other high alumina bricks with tunnel kiln firing is generally 1500 〜 1600 ℃.
How To Choose Steam Boiler Refractory Brick Material?
According to the different resource conditions and product requirements, the following types of raw materials can be used: high alumina bauxite with aqueous alumina minerals (alumina monohydrate, alumina trihydrate, 等) as the main composition. Silica line group minerals (including sapphire, ロードクロサイト, silica line, 等); synthetic raw materials, such as industrial alumina, synthetic mullite, electrofused corundum, 等.
China’s high alumina vanadium clay resources are abundant, excellent texture, the origin is mainly distributed in Shanxi, Henan, Hebei, Guizhou, Shandong, と他の場所. The high alumina vanadium clay produced is mainly a mixture of two minerals, alumina monohydrate, and kaolinite.
When purchasing high alumina brick, first of all, the color, high-quality high alumina brick body surface is smooth, yellow color white, equal on all sides, no broken corner, 亀裂なし.
The second point is to weigh the weight of a single brick. According to the weight standard, a single weight of high alumina brick is 4.5 kg, two high alumina bricks for 4.2 kg, and three high alumina bricks for 3.9 kg.
At the same level, the same model of high alumina brick, if the weight of a single brick reaches this standard, but for high alumina brick, and vice versa can not reach such weight, it means good quality. If you find that there are cracks, large pieces of broken corners, and four sides are not equal, it is a substandard product.
