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 .

Abstract

The invention provides a novel electrode structure for a resistance furnace. The novel electrode structure for the resistance furnace comprises an electrode base and an electrode arranged in a center hole of the electrode base. An O-shaped ring used for sealing is arranged outside the electrode. A screwing nut is arranged at the bottom of the electrode. Insulating material is arranged between the electrode and the electrode base. The electrode structure can meet requirements for high-temperature and high-pressure sealing in equipment, can be adjusted in size and can adapt to different current and voltage requirements. The electrode structure is compact in structure and convenient to manufacture and install, well solves the problems of electrode structure sealing, insulating, cost and many other respects, and is very suitable for continuous high temperature environments of the resistance furnace.

Description

technical field [0001] The invention relates to a novel electrode structure, in particular to a novel electrode structure for a resistance furnace. Background technique [0002] Resistance furnace is a kind of industrial furnace, which is widely used in machinery, electronics, aerospace, aviation, weapons, metallurgy, chemical industry, food, light industry, building materials, ceramics, medicine and many other industrial fields. Industrial heating equipment, that is, industrial furnaces, can be divided into electric heating and fuel heating according to heating energy and energy conversion methods, that is, electric furnaces and flame furnaces. Flame furnaces are mainly used in industrial fields such as steel, metallurgy and automobiles; in the electronics industry, the heating process specifications for parts and materials, such as degassing, setting, annealing, purification, purification, sintering, coating, blackening, sealing, etc. , you need to use a resistance furnac...
