The invention relates to a
glass ceramic pipe and a preparation method thereof. The
glass ceramic pipe is prepared from the following raw materials in percentage by weight: 20 to 40 percent of
coal ash, 20 to 50 percent of
slag obtained by separating Baiyunebo
tailings again, 0 to 40 percent of
blast furnace slag or steel
slag, 15 to 30 percent of
quartz sand, 2 to 5 percent of
sodium carbonate, 2 to 7 percent of
borax, 0 to 5 percent of
dolomite or
lime stone, and 0 to 6 percent of
albite or
potash feldspar; and the preparation method comprises the following steps of: measuring the raw materials according to the ratio and then adding into a ball-milling mixing
machine and mixing uniformly and melting the mixture at the temperature of between 1,350 and 1,450 DEG C; and performing centrifugal
casting and molding; annealing,
coring and crystallizing the molded
pipe, and reducing the temperature at a speed of 1 to 5 DEG / min to the temperature of less than 100 DEG C and then discharging. The product has good performance, the
abrasive resistance of the product is three times higher than that of a glass-
ceramic tube, the weight of the product is only one third that of a glass-
ceramic composite tube, the service life of the product is 3 to 5 times that of the glass-
ceramic composite tube, and the
cost performance of the product is high. The
utilization rate of
industrial waste residue in the raw materials is more than and equal to 70 percent, and the pipe is energy-saving and environment-friendly, has low production cost, is suitable for large-scale industrial production and has a wide application range.
