为了节约能源、缩短玻璃生产周期，开发了多相交流电弧空中熔炼技术。采用6相电弧和12相电弧研究了钠钙和无碱玻璃粉的空中熔化行为。结果表明，随着输入功率的增加，原料的玻璃化程度和粒径收缩率增大。熔融温度和粘度越高，无碱玻璃粉的玻璃化程度越低。在相同的Transformer电流下，12相电弧与6相电弧相比，停留时间长，等离子体温度高，提高了原料的玻璃化程度。在短时间内获得的高玻璃化度表明，多相交流电弧空中熔化新技术将是玻璃工业节能的一种很有前途的方法。
The in-flight melting technology with multi-phase alternating current (AC) arc was developed for the purpose of saving energy and shortening production cycle for glass industry. The 6-phase arc and 12-phase arc were used to investigate the in-flight melting behavior of soda-lime and alkali-free glass powders. Results showed that the vitrification degree of raw materials and the shrinkage of particle diameter increased with the increase of input power. The higher melting temperature and viscosity were responsible for the lower vitrification degree of alkali-free glass powders. Compared with 6-phase arc, 12-phase arc improved the vitrification degree of raw material for the longer residence time and higher plasma temperature under the same transformer current. The high vitrification degree achieved in short time indicated that the new in-flight melting technology with multi-phase ac arc would be a promising method for energy conservation in glass industry.
