る。 And this graphite resistance heating element main body 2
As shown in FIG. 2, the end of the graphite is placed in a mold 8, and a molten metal 6 of copper, copper alloy, stainless steel, etc. is poured into it under an inert atmosphere to prevent the graphite from being oxidized. By injecting and solidifying the molten metal 6, the metal connection terminals 7 are cast-jointed to form the graphite resistance heating element 1.
この場合、金属製接続端子７は、グラフアイト

金属溶湯６を容易に充填することができる。 In this case, due to the presence of the engaging portions 4 and 4' of the graphite resistance heating element body 2, the graphite resistance heating element body 2 and the metal connection terminal 7 are tightly and integrally connected. state. Therefore, even if there is a difference in thermal expansion between the two, a close contact state can be ensured at either of the engaging portions 4, 4'. In addition, graphite resistance heating element body 2
When charging the molten metal 6 into the molten metal 6, the gas in the recess 3 is evacuated through the L-shaped gas vent hole 5, and the molten metal 6 can be easily filled into the recess 3.
