Study on Heating Uniformity of Pt-Rh Alloy Bushing for Producing Flexible Glass

Abstract

The numerical simulation for temperature distribution of Pt-Rh alloy bushing was carried out using a thermal-electric module in ANSYS Workbench finite element analysis software. The effects of side wall thickness, plug thickness, the angle of two side walls and electrode structure on the uniformity of temperature distribution were investigated. Meanwhile, the contrastive analysis results of bushing with and without glass melt were discussed. The simulation results show that, when the homogeneous glass melt flows through bushing, the temperature difference between the center and both ends of bushing is decreased significantly, but the temperature distribution at both ends of bushing is still affected by heating non-uniformity of bushing. Compared with side wall thickness, plug thickness and the angle of two side walls, electrode structure plays a greater role in adjusting heating uniformity of bushing.
