Mullite brick manufacturing is mainly made of mullite as the main crystalline phase of high aluminum refractory. Mullite brick is mainly used in blast furnace top, blast furnace body and furnace bottom, glass furnace heat storage chamber, ceramic sintering kiln, oil cracking system dead corner lining, etc. We are a professional refractory brick manufacturer, welcome to consult and purchase.
Mullite brick refractory higher, can reach more than 1790℃. The starting temperature of softening under load is 1600 ~ 1700℃. Normal temperature compressive strength 70 ~ 260MPa. Good thermal shock resistance.
This series of refractory brick can be divided into sintered mullite brick and electric fused mullite brick. Sintered mullite brick with high alumina clinker as the main raw material, adding a small amount of clay or raw bauxite as a binder, after forming, fired and made. Electric melting mullite brick manufacturing with high alumina, industrial alumina and refractory clay as raw materials, adding charcoal or coke as a reducing agent, formed after the use of reduction melting method to manufacture. Generally speaking, the crystal of electrofused mullite is larger than that of sintered mullite, and the thermal shock resistance is better than that of sintered mullite. Their high temperature properties mainly depend on the content of alumina and the uniformity of mullite phase and glass distribution.
Mullite refractory bricks has good chemical stability, high temperature resistance, high dimensional accuracy, uniform structure, beautiful appearance, low thermal conductivity.
According to the requirements of special refractories production, using the composite additive burning method the development and production of fine material, mullite brick manufacturing have higher temperature, can be directly contact with flame, low production cost, simple manufacturing process, the energy saving effect is remarkable, stable and reliable product performance and quality, get a lot of praise and trust of users.
We are a high quality refractory products manufacturers, with more than 20 years of production experience, strong technical force, refractory products of high quality, export more than 60 countries and regions in the world, welcome to purchase.
