Ferromanganese slag microcrystalline glass and preparation method thereof

Abstract

The invention relates to a ferromanganese slag microcrystalline glass and a preparation method thereof. The ferromanganese slag microcrystalline glass is prepared from ferromanganese slag (30-50 percent), waste cullet (10-30 percent) and a powder accessory material (20-40 percent) through raw material pulverization, mixing, melting, molding, annealing, coring crystallization and cold machining. The product comprises the main components of SiO2 (50-57 percent), Fe2O3 (0.1-1.0 percent), Al2O3 (3-5 percent), CaO (20-26 percent), MgO(8-11 percent), MnO2 (3.2-5.0 percent) and Na2O(4-7 percent). The invention fully utilizes industrial wastes and effectively reduces the cost of raw materials; the product has favorable performance, such as high mechanical strength, large hardness, favorable corrosion resistance, abrasion resistance, and the like; and the product can be made into various pipes and plants and widely applied to an abrasion and corrosion resistant material of construction or a construction decorating material.

Description

technical field [0001] The invention belongs to the field of glass-ceramics and relates to slag glass-ceramics whose main crystal phases are wollastonite, diopside and part of anorthite. In particular, it relates to the technical field of producing glass-ceramic as the main raw materials of ferromanganese smelting waste slag—ferromanganese slag and waste cullet. Background technique [0002] Waste slag glass-ceramic is a glass-ceramic prepared mainly from various metallurgical waste slag, industrial and mining tailings, and fly ash from thermal power plants. Glass-ceramic, also known as glass-ceramic, is a new type of material developed by combining glass and ceramic technology. Such as high mechanical strength, corrosion resistance, heat resistance, wear resistance, good oxidation resistance, excellent electrical properties, adjustable expansion coefficient, good thermal stability, etc., and is superior to natural stone and ceramics, and can be used for building curtain wa...

AI Technical Summary

Problems solved by technology

However, there is no report on the research and production of glass-ceramics prepared from ferromanganese slag as the main raw material.

There is a large amount of this kind of industrial waste in China, and it is piled up in the open air, which not only occupies the land, but also easily causes dust pollution, mudslides, blockage of rivers, pollutes water sources and endangers the environment.
