Refractories (Refractory material) selection and matching recommendations (five) in the top of the hot parts of the kiln feed castable models, including the tail with subsequent decomposition kiln barrel, preheater and calciner systems, tertiary air duct and cooler temperature area, all lining the surface temperature of not more than 1200 ℃ site should be used clay refractories (Refractory material), including the series of alkali-resistant brick, alkali and other castable and ordinary clay. In the parts of the new dry kiln and kiln Lepol optimum use of alkali brick series, including ordinary acid brick for preheating and cone body parts as well as formula cooler temperature zone for high strength and tertiary air duct alkali-resistant bricks, insulation bricks for kiln alkali and aluminum-rich tail tube type vault for vault with bricks and the corresponding alkali alkali castable. Refractories (Refractory material) the true density is the true density refractories (Refractory material) in the solid mass to its true volume (volume of solid portion) ratio. True specific gravity is the ratio of the true mass of the unit volume of the material mass and 4 ℃ unit volume of water. Both can be considered the same in value. The international community has a true specific gravity of this concept is no longer used, but in Japan refractories (Refractory material) Technology Association of editing and publishing the "refractories (Refractory material) Handbook," a book castable recipes, still using the true proportion. Refractories (Refractory material) in the true density is a measure of quartz silica brick extent of conversion of important technical indicators. Different true density of SiO2 composition of the various minerals, the true density of the minimum phosphorus cristobalite, cristobalite, followed by quartz maximum. In the study of phase transitions multiphase material castable thermal conductivity, chemical composition in a certain time, according to the true density of the data to determine the phase composition of the material. For the true density of refractory products and refractory materials, according to the national standard GB / T5071-1997 (identical with ISO5018: 1983) were measured. Castable thermal conductivity, Chengdu castable refractory shangzhuang provided by shangzhuang Refractories Co., Ltd., Zhengzhou City. Zhengzhou City shangzhuang Refractories Co.
