With the international publicity on energy conservation and environmental protection, the market of refractory materials also adapt to change, high alumina refractory brick as the most common refractory one, people have higher and higher requirements on it, not only stay in the quality of high alumina brick for sale, now more attention will be paid to whether the product environmental protection and other aspects.
So do you know the role of high alumina refractory brick in the whole construction? Next, I will give you a brief introduction.
High alumina refractory brick for sale, mainly used for lining blast furnace, hot blast furnace, electric furnace top, blast furnace, reverberatory furnace, rotary kiln etc. In addition, high aluminum brick is also widely used as open hearth regenerative type lattice brick, pouring system plug head, nozzle brick, etc.
The refractory degree of high alumina brick is higher than that of clay brick, which can reach 1750~1790℃, it is a high quality refractory. Because of high aluminum in Al2O3, miscellaneous quality is little, there are fewer fusible forms of vitreous, so the softening temperature under load is higher than that of clay bricks. However, the softening temperature under load is not as high as that of silicon brick as mullite crystals do not form reticular structure.
Moreover, Al2O3 is more in high alumina refractory brick for sale, which is close to neutral refractory materials. It can resist the erosion of acid slag and alkaline slag. Because of the content of SiO2, the resistance of alkaline slag is weaker than that of acid slag.
High alumina refractory bricks for sale widely, mainly used for lining blast furnace, hot blast furnace, electric top, blast furnace, reverberatory furnace, inner lining of rotary kiln, electric steelmaking furnace, glass furnace, and lining of cement rotary furnace. It can effectively improve the service life of kiln.
