The Flow Of Glass In The Working End And Throat Of An Electrically Heated Glass Tank (In German)

An electrically heated glass tank with a production of 4t/24h has been developed in Hradec Kralove. It is a notable feature of this tank that the working end and throat are divided longitudinally by a vertical wall. To investigate the flow of glass a 1/5 scale model was built which used a mixture of glycerine and glucose syrup as the fluid. The flow in the throat and working end was investigated when the pull was the same from both halves and also when it was different. The results confirm the usefulness of the new furnace in practice.
