Embodiment 1
[0045] Such as figure 1 As shown, a novel electrode structure for a resistance furnace provided by the present invention includes an electrode base 5, and the center of the electrode base 5 has a hole with upper and lower steps. The electrode 11 is provided with a shaft shoulder 7 on the top of the electrode 11, and the outer diameter of the shaft shoulder 7 of the electrode 11 is 1 mm smaller than the inner diameter of the step hole at the top of the center hole of the electrode seat 5. The inner diameter of the central hole of the electrode seat 5 is 2mm larger than the outer diameter of the electrode 11. The inside of the electrode 11 is provided with a cooling hole 6, and the bottom of the electrode 11 is threaded. The electrode 11 passes through the center of the hole of the electrode seat 5, the top goes deep into the device, and the bottom is outside the device.
[0046] The electrode 11 is connected with the tightening nut 1 through the bottom thread, and the upper p...
Embodiment 2
[0051] according to figure 2 As shown, the present invention provides a new electrode structure for electric resistance furnace. Another embodiment of the present invention differs from this embodiment in that the top of the polytetrafluoroethylene cylinder 9 is in direct contact with the shaft shoulder 7 . The sum of the height of the polytetrafluoroethylene cylinder 9 and the wire diameter of the middle O-ring 10 is 2.5 mm larger than the height of the upper step in the center hole of the electrode holder 5 .
