Engineering Simulation Research Of 200t/d High-aluminum Electronic Glass In An Electric Boost Melting Furnace

The use of ultra-thin high-aluminum electronic glass has widely increased with the development of electronic products.The percentage of Al2O3 in high-aluminum glass is higher than that of common glass.Given that the melting point of Al2O3 is 2050 °C,this compound requires higher melting temperature than common glass.Given the conductivity of molten glass,electric energy is used to heat glass directly and increase the heat-transfer efficiency.During glass production,the flame space temperature can simultaneously decrease and adopt an appropriate electric boost melting scheme to melt glass and compensate for the lost heat,thereby addressing the problem of evenly heated high-aluminum glass.The local 200t/d high-aluminum glass liquid was used as the research object in this simulation study to explore the changes in temperature and velocity inside the glass material with the electrode.The loading electrode was analyzed with the ANSYS Fluent 14.0 software module.Simultaneously,changes in the melt and the clarify index were analyzed,as well as the circulation flow changes in the glass melting furnace.Results showed that compared with the same scale of high-aluminum glass melting furnace before the hot spot,the glass s urface temperature can be decreased in the electric boost melting furnace.The electric heat can compensate for the decreased influence of the surface temperature before the hot spot.In the high-aluminum glass electric boost melting furnace,the glass liq uid flow velocity in the melting region obviously increased.Simultaneously,obvious convection existed for the glass liquid around the electrodes.This phenomenon is advantageous to glass homogenization.The high-aluminum glass electric boost melting furnace scheme increased the daily circulation of cycles I and II,which can improve the properties of the glass melt and the homogenization for glass uniformity.By contrast,the decrease in cycle III will be advantage to improve the stability of the temperature and composition of the glass.Given a high-aluminum glass melting furnace melt index of IM = 1.21,the high-aluminum glass electric boost melting furnace melt index is IM = 1.24.This finding proved that electric energy can be used to heat glass materials.After optimization for the electric fusion scheme,the melt index IM = 1.00,and the clarify index IR = 1.02.It showed that the reasonable configuration to achieve full of glass melting and clarification.The same furnace,simply reducing yields,the hot spot position within a certain scope has a linear relation with the amount of pull to move forward,the height of the forward flow decrease when the glass flew out of furnace,using electricity to melt and simply reduce the yields,the melting furnace of glass fluid flow showed the same trend.
