摘要：

Several progress have taken place since the installation of an all-electric tank furnace supplying molten glass to glass forming machines by Czech glassmaker, Sklarny Kavalier, 35 years ago. Improvements were made for the control of electric glass-melting furnaces and the need for skilled operators to operate such furnaces were required. Operators not only need active control elements but also parameters defining the tank conditions more accurately and which can reflect the changes in the melting process quickly. The control system based on keeping constant electric resistance in the melting end as a whole is the most frequently used. The electric resistance can be coupled direct to the input control and the control system based on the constant resistance adjusts the set point of the controller to the constant input. The development of computer technology and instrumentation has made it possible to see processes in the furnace, and assess them with the aim to eliminate irregularities.
