High Alumina Fire Bricks32

1. Product Name:High Alumina Fire Bricks

2. Product Description:?Product Introdution? High alumina fire brick is with a content of more than 55%.Using high bauxite clinker as the main raw material, soft clay and waste pulp and paper liquid as binder, multi-stage particle ratio of mud, through high pressure molding, drying, high temperature firing.The high alumina bricks are classified according to their mineral composition: low mullite, mullite, mullite, corundum-mullite and corundum. The mineral composition is mainly corundum, mullite and glass facies. ?Product Specifications? The specification size of high aluminum fire brick is 230*114*65mm, also known as T-3 super refractory brick.All kinds of specifications and sizes can be produced by drawing. High Alumina Fire Bricks7 ?Product Classify? High aluminum fire brick according to the content of aluminum oxide is different, divided into four grades: Super grade high aluminum brick is three oxide two aluminum content is more than 80%; The first level of high aluminum brick is the content of aluminum oxide 75-80%; Secondary high aluminum brick is the content of aluminum oxide 60%-75%; Three high aluminum brick is three oxide two aluminum content 48%-60%; ?Physical and chemical indicators?

(1) fire resistance.The refractory of high aluminum brick is higher than that of clay brick and semi-silicon brick, up to 1750-1790 degrees, which belongs to senior refractory materials. (2) load softening temperature.Because high aluminum products in Al?O? high, less mixed quality, forming less fusible vitreous, so the load softening temperature is higher than the clay brick, high aluminum load softening temperature is generally above 1420-1550 degrees.But because mullite crystals do not form a network, so the softening temperature under load is not as high as the silicon brick. (3) slag resistance.High aluminum brick in Al?O? more, close to neutral refractories, can resist the erosion of acid slag and alkaline slag, because it contains SIO ?, so the ability to resist alkaline slag than the ability to resist acid slag. (4) chemical corrosion resistance.High aluminum refractory products resistance to acid or alkaline slag, metal liquid erosion and oxidation, reduction reaction is very good, and with the increase of the content of Al?O?, the reduction of harmful impurities. ?Product use? High alumina brick is mainly used for the lining of blast furnace, hot blast furnace, top of electric furnace, blast furnace, reflection furnace and rotary kiln.In addition, high alumina brick is also widely used as open hearse regenerative lattice brick, gating system plug head, nozzle stone, etc.
