The different uses of high alumina bricks
High alumina refractory bricks , also known as high alumina brick, and its production and stickers brick production process is similar to the difference is more with high-alumina clinker powder, refractoriness than clay brick, anti-acid and alkali resistance candle better performance It is used in various kiln firing zones. Al2O3 content of more than 48% of the aluminum silicate refractory bricks are collectively referred to as high alumina refractory bricks. (Al2O3 is 60% ~ 75%); Ⅲ and so on (Al2O3 is 48% ~ 60%). The Al2O3 content is divided into three grades: I and so on (Al2O3> 75%); According to the mineral composition can be divided into: low mullite (including sillimanite) and mullite (Al2O3 for 48% ~ 71.8%), mullite - corundum and corundum - 71.8% ~ 95%), corundum (Al2O3 95% ~ 100%) and other refractory bricks. With the increase in Al2O3 content in high alumina bricks , the number of mullite and corundum components also increased, the glass phase de...
