Numerical Simulation of Stone Wool Melt in Direct Current Furnace
摘要
Abstract
ANSYS software was used for numerical simulation of stone wool melt in electric melting furnace.Under stable voltage 130 V,stable melt height 1 600 mm and stable inlet and outlet state,the insertion depth of cathode electrode was changed to study the temperature distribution,flow field distribution and current density distribution of the melting in electric melting furnace.The results show that the melt forms a high temperature zone between the cathode and anode and around the electrode,The temperature decreases from anode to cathode and from top to bottom on the symmetrical side of the inlet,while the temperature increases from top to bottom on the inlet side.With the increase of cathode insertion depth,the overall temperature and corresponding current density of the melt increase.The deeper the cathode insertion depth is,the greater the temperature rise of the whole temperature field is.At the inlet side and the outlet side,the melt forms a circulation due to natural convection,and the self-stirring and self-homogenization of the circulation have important technological significance for melt homogenization.Changing the cathode insertion depth can improve the melt control ability and improve the subsequent fiber forming effect and quality.关键词
