Embodiment 1
[0031] (1) Preparation of hollow rod
[0032] Get 100 kilograms of carbon black and 20 kilograms of coal tar pitch and mix, and make stick;
[0033] Put the rod-shaped body into a roasting tank filled with roasting powder, and then put the roasting tank into a roasting kiln for roasting—that is, it takes 3 days to burn to 650°C, and then burns to 800°C in 3 days. The roasting tank with rods is taken out from the kiln, buried in sand and air-isolated and lowered to normal temperature (20-30°C); open the roasting tank, take out the rods, and place them in a rotating drum to remove the roasting on the rods. powder gravel;
[0034] Take out the rod-shaped body from which the baked powder and gravel have been removed, use a crusher to crush the rod-shaped body into particles with a diameter not greater than 5 mm, and add 20 kg of graphite to the rod-shaped body particles, and grind them together to form a 200-mesh mixed fine powder;
[0035] Add the above-mentioned mixed micropow...
Embodiment 2
[0044] (1) Preparation of hollow rod
[0045] Get 100 kilograms of carbon black and 50 kilograms of coal tar pitch and mix, and make flake;
[0046] Put the flakes into a roasting tank filled with roasting powder, put the roasting tank into a roasting kiln and bake it—that is, burn it to 550°C in 24 hours, and then burn it to 1050°C in 96 hours. The roasting tank with flakes is taken out from the roasting kiln, buried in sand and isolated from the air, and lowered to normal temperature (20-30°C); open the roasting tank, take out the flakes, and place them in a rotating drum to remove the flakes. baking powder grit;
[0047] Take out the flakes from which the baked powder has been removed, use a crusher to crush the flakes into particles with a diameter not greater than 5 mm, add 10 kg of graphite to the flake particles, and grind them together to form a 100-mesh mixed fine powder ;
[0048] Add the above-mentioned mixed fine powder into a kneader with a temperature of 200°C...
Embodiment 3
[0057] (1) Preparation of hollow rod
[0058] Get 100 kilograms of carbon black and 40 kilograms of coal tar pitch and mix, and make stick;
[0059] Put the rod-shaped body into a roasting pot with roasting powder, put the roasting pot into a roasting kiln and roast it—that is, burn it to 600°C in 48 hours, and then burn it to 1100°C in 48 hours. The rod-shaped roasting tank is taken out of the roasting kiln, buried in sand and isolated from the air, and lowered to normal temperature (20-30°C); open the roasting tank, take out the slice, and place it in a rotating drum to remove the roasted powder and gravel on the rod-shaped body ;
[0060] Take out the rod-shaped body from which the baked powder and gravel have been removed, use a crusher to crush the rod-shaped body into particles with a diameter not greater than 5 mm, add 30 kg of graphite to the rod-shaped body particles, and grind them together to form a 150-mesh mixed fine powder;
[0061] Add the above-mentioned mixe...
