摘　　要：针对现有池窑法生产连续玄武岩纤维中存在的问题,采用等离子体技术设计一种池窑,通过数学模型对其进行仿真计算模拟,并通过实验验证等离子体炬功率、加热时间对池窑温度的影响。结果表明:将等离子体技术应用于池窑,通过调节等离子体炬功率可调整等离子体火焰温度,使池窑平均温度达1500℃左右,从而满足熔池的工艺要求;在池窑法生产装置上投入等离子体炬进行实验,启动等离子体炬,使功率迅速达160 kW,加热1 h以上,整个熔池达到热态平衡,池窑底部温度和表面温度均保持在1500℃左右,可以满足整个熔池纤维溶液的温度要求;等离子体技术应用于连续玄武岩纤维的池窑法生产工艺,以电能作为热源替代天然气热源,池窑温度、温度分布均匀性、停留时间等技术参数均能满足玄武岩纤维的生产工艺要求。In response to the problems existing in the production of continuous basalt fibers by pool kiln method,a pool kiln was designed by plasma technology and was calculated and simulated through mathematical models.And the effects of plasma torch power and heating time on the pool kiln temperature were verified through experiments.The results showed that the plasma flame temperature can be adjusted by adjusting the plasma torch power when the plasma technology was applied in pool kiln,so as to make an average temperature of pool kiln reach 1500℃or so,thereby meeting the process demand of melt pool;the plasma torch was experimentally applied into the production equipment of the pool kiln method,the entire melt pool reached thermal equilibrium and the bottom and surface temperatures of the pool kiln were maintained at around 1500℃,which can meet the temperature requirements of the fiber solution in the melt pool,when the power of the plasma torch rapidly reached 160 kW and the heating time exceeded 1 h;and the technical parameters such as pool kiln temperature,temperature distribution uniformity and residence time can all meet the production process requirements of basalt fibers when the plasma technology was applied in the production process of continuous basalt fibers by pool kiln method using electricity as a heat source instead of natural gas.
