产品介绍
三氧化二铝(Al2O3)含量高于48％的硅酸铝质耐火材料制品。按高铝砖中Al2O3含量通常分成三等:Ⅰ等──Al2O3含量＞75％；Ⅱ等──Al2O3含量为 60～75％；Ⅲ等──Al2O3含量为48～60％。
特级高铝砖是氧化铝含量不低于80%的一种中性耐火材料。由矾土或其他氧化铝含量较高的原料经成型和煅烧而成。热稳定性高，耐火度在1770℃以上。抗渣性较好主要用于砌筑高炉、热风炉、电炉炉顶、鼓风炉、反射炉、回转窑内衬。此外，高铝砖还广泛地用做平炉蓄热式格子砖、浇注系统用的塞头、水口砖等。通用高铝砖（即T字头砖）、异型高铝砖、高炉砖（即G字头砖）
产品特点
1、耐压强度：经客户使用对比，东阳耐材的产品在同等重量同等含铝量情况下普遍较其他厂家一级高铝砖高2~4个MPa
2、热导率：单位温度梯度条件下，通过材料单位面积上热流速率，跟气孔率有关。
3、耐冲击性：耐冲击性好，使用寿命就长。
4、抗渣性：在高温下抵抗熔渣侵蚀作用而不被破坏的能力 。

Product introduction
Three two aluminum oxide (Al2O3) was higher than that of aluminium silicate refractory products 48%. The content of Al2O3 in high alumina brick is usually divided into three equal: I and so on - Al2O3 content > 75%; II and so on - Al2O3 content is 60 ~ 75%; III and so on - Al2O3 content is 48 ~ 60%.
Special grade high alumina brick is a kind of neutral refractory with no less than 80% of alumina content. From bauxite or other high content of alumina raw materials forming and firing. High thermal stability, fire resistance at 1770. Good slag resistance mainly used in blast furnace, hot blast furnace, furnace furnace, blast furnace, reverberatory furnace, rotary kiln lining. In addition, high alumina bricks are widely used as furnace regenerative checker, pouring system for plug nozzle, etc.. General high aluminum brick (T prefix brick), special-shaped high alumina brick, blast furnace brick (G prefix brick)
Product features
1, the compressive strength: the customer use of contrast, Dongyang refractory products in equal weight the same Al content generally than other manufacturers a grade high alumina bricks 2-4 a MPa
2, thermal conductivity: unit temperature gradient conditions, through the material unit area of heat flow rate, with the porosity of the relevant.
3, impact resistance: impact resistance is good, the service life is long.
4, the slag resistance: resistance to slag erosion under high temperature and not destroyed.
Product use
High alumina bricks are mainly used in masonry ceramic frit kiln, sodium silicate alkali furnace, glass furnace, blast furnace, hot blast furnace, electric furnace, blast furnace, reverberatory furnace, rotary kiln lining. In addition, high alumina bricks are widely used as furnace regenerative checker, pouring system for plug nozzle, etc..
