Product description
Wear Resistant Ceramic Brick Alumina Lining Brick
There are many kinds of Light weight fire brick. Hongtai resistance materials introduce you to lightweight high aluminum bricks and alumina hollow ball bricks.These two products have excellent thermal insulation performance and are applied to various thermal equipment to reduce heat loss and improve production efficiency.
Light weight fire brick is also called high-alumina insulation brick with alumina content of more than 48%.Volume density: 0.4-1.35 g/cm3.The porosity is 66% ~ 73%, and the compressive strength is 1 ~ 8MPa.Good thermal shock resistance.Usually use high bauxite clinker and a small amount of clay, the fine grinding method or bubble method using gas before and after the pouring and forming in the form of mud, burn into the 1300 ~ 1500 ℃.Sometimes industrial alumina can be used instead of some alumina clinker.Used for lining and insulating layer of kiln furnace, as well as parts without strong high temperature melting material erosion and scour.Direct contact with the flame, the contact surface temperature is not higher than 1350 ℃.
Alumina hollow ball is a new kind of high temperature heat insulation material, which is made by smelting and blowing of industrial alumina in electric furnace.In alumina hollow ball as the main body, can be made into various shapes, the highest temperature 1800 ℃, high mechanical strength, general light products several times, and the bulk density is only half of the corundum products.It has been widely used in high temperature and ultra-high temperature kilns such as petrochemical gasifier, carbon black industrial reaction furnace and induction furnace in metallurgical industry.
