Product description:Al2O3 content is higher than 48% aluminum silicate refractory products.A neutral refractory with an alumina content of more than 48%.The raw materials of alumina or other high alumina are formed and calcined.The thermal stability is high and the fire resistance is above 1770.Good slag resistance, used for lining steel furnaces, glass furnaces, cement rotary furnaces, etc.High alumina brick high - load soft, low - creep high - alumina brick is made of special grade bauxite, electrofused corundum, electrofused mullite as the main raw material.This product has the high temperature creep and have good thermal shock resistance, erosion resistance and other advantages, is suitable for large and medium-sized stove, it is needed for high quality, high grade new type hot blast stove in China imported refractory localization opened up a road to success, has been included in the national "spark plan" project.Characteristics of high alumina brick: - Good thermal stability;
2. High refractoriness and load softening temperature;3. It is divided into standard shape, normal shape, abnormity and special shape brick.The use of High alumina firebrick: mainly used for masonry ceramic melting furnace, foam base kiln, glass kiln, blast furnace, stove top, blast furnace, reverberatory furnace, rotary kiln Lining.In addition, the high alumina brick is widely used for the open-hearth heat storage grid, pouring system of plug head, water brick and so on.High alumina firebrick classification: according to Al2O3 content in high alumina brick, it is usually divided into three types:1.The content of Al2O3 is 75%;2.The content of Al2O3 is 60 ~ 75%;3.The content of Al2O3 is 48 ~ 60%.
