摘要:

电助熔系统设计的合理与否直接影响玄武岩池窑的熔制效率。本文基于CFD方法对玄武岩池窑中的火焰燃烧、原料熔化以及熔液流动三大空间进行热耦合模拟,研究电极电流密度、电极长度、电极布置高度、布置方式等关键参数对电助熔池窑熔制均匀性的影响,为电助熔系统的优化设计提供理论指导。结果表明:池窑出口温度随电流密度增大、电极布置高度增加以及电极长度的增加而升高。此外,当电流密度大于2500A/m2、电极布置在池深方向的中下方、电极长度大于350mm以及电极采用横插方式时,熔液空间具有较好的熔化均匀性,且池窑出口熔液温度均高于1360℃,有利于后续的拉丝作业。

Abstract:

A reasonable design of electric boosting system directly affects the melting efficiency of basalt furnace. A thermal coupling simulation of the three spaces of flame combustion, raw material melting and molten liquid flow in basalt tank furnace were performed based on CFD method. Effects of key parameters including electrode current density, electrode length, disposal height and layout mode on the melting uniformity of tank furnace were investigated, which provided theoretical guidance for the optimal design of the electric boosting system. The results showed that the outlet temperature of the tank increased with the increase of current density, electrode arrangement height and electrode length. In addition, better melting uniformity of the melt space and higher than 1360℃ of melt temperature at the outlet of tank furnace could be obtained when the current density was more than 2500A/m2, the electrodes were arranged in the middle and lower part of the pool depth direction, the electrode length was more than 350mm and the electrodes were inserted horizontally. Thus, it was conducive to the subsequent wire drawing operation.

Key words: basalt fiber, tank furnace, electric boosting, uniformity, numerical simulation
