In refractory industry, there are many kinds of refractory brick, and high alumina bricks is one of them. This series of refractory products has been widely used, its performance has won the love and recognition of new and old customers, I plant production of high aluminum bricks exported to the Philippines, the United States, the United Kingdom, southeast Asia, Africa and other countries and regions, you are welcome to come to consult and purchase.
High alumina bricks production raw materials can be different according to the requirements of the products, can use the following types of raw materials: water aluminum oxide minerals (bauxite, sanshui bauxite, etc.) high alumina brick as the main component of high alumina; Silylinite group minerals (including cyanite, andalusite, silylinite, etc.); Synthetic raw materials, such as industrial alumina, synthetic mullite, fused corundum etc.
According to the craft of this series of refractory brick, high alumina brick and clinker clay brick’s produce technology more similar, the difference is that the ingredients in the clinker ratio is higher, can be as high as 90 ~ 95%, before breaking the clinker grading sorting and screening in addition to iron, firing temperature is higher, such as Ⅰ, Ⅱ high alumina brick with tunnel kiln firing when the general is 1500 ~ 1600 ℃. We have proved by practice that the high aluminum clinker in the crushing before the strict selection and classification, and classification storage, the use of alumina clinker and combined with clay joint fine grinding method, can improve product quality.
High Alumina Bricks Feature
1. The refractory of high aluminum brick is higher than that of clay brick and semi-silicon brick, reaching 1750~1790℃, which belongs to advanced refractory.
2. Al2O3 in high aluminum products is high, less miscellaneous mass, less fusible vitreous.
3. High alumina brick Al2O3 more, can resist acid slag and alkaline slag corrosion.
High alumina brick is mainly used for lining of blast furnace, hot air furnace, electric furnace top, blast furnace, reflection furnace and rotary kiln. In addition, high alumina brick is also widely used as open hearth regenerative lattice brick, pouring system with plug head, nozzle brick. But the price of high aluminium brick wants to compare clay brick tall, so, the place that can satisfy a requirement with clay brick need not use high aluminium brick.
