摘要
为提升高碳铬铁渣再利用附加值,采用高碳铬铁渣制备微晶玻璃。首先在分析高碳铬铁渣成分的基础上,结合热力学软件计算,研究确定微晶玻璃体系、各成分含量范围、原料种类及配比,并通过拉曼光谱等方法研究实验制备得到的基础玻璃及微晶玻璃成品,分析微晶玻璃体系的可行性。研究表明:以辉石类晶体及霞石为主晶相,以高碳铬铁渣及废玻璃为主要原料的微晶玻璃,经过物料配比调整,可有效减少桥氧键的数量,降低体系聚合度,进而降低黏度,解决了高碳铬铁渣高熔点、黏度大带来的工艺问题。微晶玻璃成品的XRD图谱表明,高碳铬铁渣成功制备出了辉石霞石复合体系微晶玻璃,与热力学计算结果相一致,验证了设计体系的可行性。
In order to improve the utilization of high-carbon ferrochrome slag, glass-ceramics was prepared with it. Firstly, based on the analysis of the composition of high-carbon ferrochrome slag, combined with the calculation of thermodynamic software, the glass-ceramics system, the content range of each component, the types of raw materials and the proportion were studied and determined. In addition, the parent glass and glass-ceramics prepared by experiments were studied by Raman spectroscopy and other methods, and the feasibility of the microcrystalline glass system was analyzed. The research showed that, the glass-ceramics which was mainly consist of pyroxene crystals and nepheline phase, prepared mainly by high-carbon ferrochrome slag and waste glass, could have a lower number of bridged oxygen bonds, degree of polymerization, and viscosity after material proportion adjustment. And it solved the process problems caused by high melting point and high viscosity of the slag. The XRD result of the glass-ceramics showed that the pyroxene-nepheline-composite glass-ceramics had been successfully prepared, which was consistent with the thermodynamic calculation results and verified the feasibility of the system designed.
