| Abstract |
| The electric tank furnace with the vertical molybdenum electrodes
which became a basis for the development of the contemporary
electric furnace of the State Glass Research Institute (SVOS) type
is described. The trends of research and methods, which contributed
to gradual improving of this furnace type, are shown. In Czechoslovakia
about 20 electric tanks of the SVOS type with the output
ranging from 0.4 t/day to 8 t/day are in operation at present. The
parameters of some melting aggregates are briefly reported. The
aggregates are largely used for melting technical and domestic
glasses, illuminating glasses, glasses for imitation jewellery etc.
Recently the electric melting has been extended to lead glasses with
6-24% PbO melted in aggregates with the ;anodic operation to
molybdenum electrodes. The results of Mo-electrode and refractory
corrosion including assumptions for the frequency of the electrode
shift and aggregate working life from the standpoint of the soldier
block corrosion in melting end are shown. In the conclusion of the
paper further trends of the electric glass melting research are indicated. |
