According to the Ministry of Science and Technology of Inner Mongolia Autonomous Region, Inner Mongolia University of Science and Technology developed and produced 500 tons of nano-crystalline glass composite pipes with glass ceramics and metal properties using solid wastes such as Baiyun'ebo tailings, steel slag, iron slag, and fly ash. This new type of material has not been reported at home and abroad at present, and the relevant national departments have publicized this material as a national standard on December 10. The Baiyun Ebo Mine is a polymetallic symbiotic iron ore that is characterized by rare earths. Baotou Steel produces 7 million tons of tailings per year. At the same time, it discharges more than 4 million tons of steel slag and iron slag every year. It contains a certain amount of rare earth, antimony, iron and other metal elements. . Prof. Li Baowei from Inner Mongolia University of Science and Technology has led the task force to establish a laboratory for comprehensive utilization of polymetallic resources in the Baiyun Ebo Mine in Inner Mongolia since 2004 to study the production of high-performance glass-ceramics from solid wastes such as Baiyun Ebo tailings and fly ash. The study found that the iron, niobium, rare earth and fluorspar of the Bayan Obo tailings, steel slag and iron residue can be used as a compound nucleating agent, which is complementary to the silicon, calcium and aluminum in the fly ash and meets the basic composition requirements of the glass-ceramics. . Since 2009, the research group has adopted the melt-centrifugal casting method to prepare glass-ceramics, conducted research on the process control of nanocrystalline grains of glass-ceramics, designed formulas, and conducted experiments. A complete set of equipment suitable for the production of glass-ceramics tubing was developed, a molding process for glass-ceramics tubing was optimized, and a pilot production line of microcrystalline glass tubing with a daily production capacity of 3,000 kg was constructed. Tested by the National Building Materials Testing Center, this glass-ceramic tube has a flexural strength of 192 MPa (metal properties), an acid resistance of more than 99%, an alkali resistance of more than 97%, a Mohs strength of nearly 9 times that of diamond, and wear resistance. Less than 0.04 grams per square centimeter, with a bulk density of 3.2 grams per cubic centimeter. Tianlong Concrete Co., Ltd. of Baotou City tried the pipe, and its pipeline service life increased 3-4 times.
