Abstract
The invention discloses a light high-aluminum heat preservation refractory brick and a production method thereof, and relates to the field of heat preservation refractory materials. The light high-aluminum heat preservation refractory brick is prepared from 30-60 parts of high-aluminum bauxite, 5-10 parts of clay, 20-50 parts of raw bauxite, 10-30 parts of ignition lost matter and 8-12 parts of water. The production method comprises the production steps of raw material mixing, mud preparing by adding water, forming by pressing, calcining, natural cooling and packaging. According to the light high-aluminum heat preservation refractory brick, little water is needed, the drying step is omitted in the production process, therefore, the production time is saved, sites and operating personnel which are needed by production are reduced, and the yield is increased; the shrinking percentage can be controlled, therefore, cutting after forming is omitted, dust and noise are avoided, and meanwhile the finished product rate is increased; through the ignition lost matter adopted in the raw materials, no waste gas is generated in the firing process.
