High alumina brick kiln castable refractory shangzhuang, high alumina brick kiln provided by shangzhuang castable refractories. High alumina brick kiln castable refractory _ _ shangzhuang high alumina brick kiln castable refractories Zhengzhou City shangzhuang Limited (www.yntjj.com.cn) 2013 has been newly upgraded launched Zhengzhou City shangzhuang refractories Limited discovery of new energy-saving effect compared with conventional refractory refractory, saving at least 20% -30%, in spite of this new type of refractory disposable sales price higher than conventional refractory, but the It's very low maintenance costs. According to statistics, the use of this energy-saving, environmental protection, and efficient refractory materials, it is only about ± 5% of the furnace temperature, and the temperature difference between the traditional refractory reach ± ??10% -30%, the cost of maintaining its traditional refractories only half about. Shangzhuang Refractories Co., Ltd., Zhengzhou City, found that to make a variety of raw material and clinker composition and particle uniformity of furnace castable high alumina brick, high alumina brick kilns to be castable mixing while adding binders to enhance the bonding strength of the blank. Such as aluminum silicate blank join combine clay, magnesia blank sulfite pulp waste kiln castable high alumina clay, silica blanks adding lime and so on. Depending on how much water content of the billet can be used semi-dry molding (containing about 5% moisture) high alumina brick kiln castable, plastic molding method (containing about 15% moisture) and grouting molding (containing about 40% moisture ). Followed by drying and firing. Casting method is to mix the ingredients and raw materials through fine grinding processes, high temperature melting, direct casting, cooling and crystallization, annealing become products.
