Because high aluminum products high Al2O3, less impurities, less fusible vitreous form, so load softening temperature higher than that of clay brick high alumina brick alumina brick, but not mullite crystalline form a network organization, so load softening temperature still no brick high. Select alumina bricks formulations usually soft clay or semi-soft clay as binding agents. While also adding a small amount of pulp waste, in order to improve the molding performance and increase green strength. Alumina bricks can produce different grades of raw material mixing formula to adjust the aluminum oxide content of products and improve the matrix composition. High alumina brick material particles and produce more products like clinker clay factors specific circumstances should be actual production characteristics of raw materials, product requirements and production conditions to determine the production process. Fai Refractories found in experience, and increase the size of coarse clinker, make products to reduce porosity and improve the structural strength of the load softening temperature, thermal shock resistance and products. In addition alumina bricks firing temperature depends on the sintering of bauxite. Clinker is finely ground and combined with high alumina brick clay common important in the production process measures, to improve the quality of its products, control the secondary reactions range mullitization plays a significant role. Together finely ground corundum lattice increases the activity, and degree of dispersion of clay in the increase in fines, can be uniformly brought into close contact with the clinker, thus allows mullitization reaction is carried out uniformly fine powder, a corresponding reduction in the a lot of secondary mullitization coarse particle surface reactions. In order to effectively control the secondary mullitization reaction is carried out in the powder, finely ground clinker and clay common ratio should be appropriate, so that the mix of free and free SiO2 AL2O3 full effect, avoid rough and then with the rest of the SiO2 corundum particles swell reaction. When thus make the mix of AL2O3 / SiO2 mass ratio slightly greater than 2.55, especially using two bauxite brick, more attention should be paid fines in appropriate proportions of clinker and clay. Fai Refractories according to years of production experience, based on customer demand, formulated to produce different specifications of high-alumina products, to meet the different needs of different levels. Fai is willing to work with you to seek common development and create a better future! Fai Refractories sincerely welcome you!
