[0002] The electric heating of the electronic glass kiln is the main way in the industry at present, and mainly uses molybdenum electrodes and tin oxide. The tin oxide electrode is the most used material because the tin oxide not only has good electrical conductivity, but also has the effect of glass clarification, so it is most widely used.

The maximum resistance is about 3000 kg or so. The traditional screw rod holding method is manually operated, which has a large working intensity. In the lengthening process of the screw rod, the stiffness is continuously reduced, which easily causes the bending and jamming of the screw rod. TECHNICAL PROBLEM
