Specific embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings and examples, but following embodiment only uses
It is described in detail the utility model, does not limit the scope of the utility model in any way.
Embodiment 1: a kind of electric furnace soldering electrodes, referring to Fig. 1-6, including electrode bar 1, panel seat 2 and brazing body 3, wherein
Brazing body 3 be electrode bar 1 with 2 soldering connection of panel seat when formed.Electrode bar 1 selects copper rod, and panel seat 2 selects copper or copper alloy system
It forms, the solder that soldering connection uses is HL313 type hard solder brazed copper.HL313 type hard solder brazed copper is existing commercially available
Material, tensile strength 383MPa, price are relatively inexpensive.The fusing point of electrode bar 1 and panel seat 2 should be higher than that soldering connection is adopted
Brazing filler metal fusing point.
Referring to Fig. 3-4, panel seat 2 is equipped with axis perpendicular to the truncated cone shape through-hole 22 of the plate face of panel seat 2, in truncated cone shape through-hole
