Thermal insulating mullite refractory brick

Thermal insulating mullite refractory brick 1.Definition: Itis mainly made of synthetic mullite as the raw material, and mullite as the host lattice. 2.Chemical formula: 3Al2O3-2SiO2. 3.Classification: Sintered mullite brick 4.Raw material: 1). Natural high-alumina bauxite and kaolin, 2). Industrial alumina and clay (kaolin or agalmatolite ) 5.Production technology Select pure raw material, proportion according to the theory consist of the mullite, produced through the process of fine grinding, ball forming (block forming), calcining with the high temperature. 6.Highlight: 1).High temperature creep property is better than the one of alumina brick made of the natural clay as raw material. 2).Refractoriness of it is better than the ones of siliceous and magnesia products. 3).Resistant erosion to acid and low alkali slag properties of it is stronger than the one of the magnesia products. 4). ISO 9001:2000 Certified company. 7.Properties: ITEM No.:HXM-75 Properties Al2O3 % ≥75% Refractoriness ≥1850°C Apparent Porosity ≤20% Bulk density ≥2.6g/cm3 Refractoriness under load at 0.2MPa ≥1600°C cold crushing strength ≥60 MPa 8.Application: Mainly used in constructing of the roof of the hot blast furnace, body and bottom of blast furnaces, dead angle lining of regenerator of the glass smelting kiln, ceramic sintering furnace, petroleum properdin system.
