Mullite Insulating Refractory Bricks Promotion
In mullite (3 2 sio2, al2o3) phase of high aluminum refractory material. General alumina content is between 65% ~ 75%. Mineral composition in addition to the mullite, contain the alumina lower also contains a small amount of glass phase and cristobalite; Containing alumina high contains a small amount of corundum.High refractoriness, can reach more than 1790 ℃. The rul start temperature of 1600 ~ 1700 ℃. Room temperature compressive strength of 70 ~ 260 mpa. Good thermal shock resistance. A sintered mullite bricks and two fused mullite brick.
Sintered mullite brick with high bauxite clinker as the main raw material, add a small amount of clay or raw bauxite as binder, forming, sintering and made. Fused mullite brick with high alumina, alumina industry and refractory clay as raw material, adding charcoal or coke fine as a reducing agent, reduction fused method is used to manufacture after forming.
