Embodiment 1
[0021] The invention provides a process for improving the electrical conductivity of copper or copper alloy, comprising:
[0022] 1), take the cathode copper plate raw material, and record;
[0023] 2), melt the raw materials weighed, and complete the melting of the raw materials;
[0024] The raw material is roasted with charcoal, the roasting voltage is 360V, and the current is 1.0KA.
[0025] 3), refining the melted raw material, and adding metal yttrium to the raw material according to the mass ratio of metal yttrium to raw material is 0.006%;
[0026] When the temperature of the furnace reaches 1100°C, cut off the power, preheat the furnace head and graphite funnel, and preheat the furnace head 1 to 2 times for 2 to 3 minutes each time. Put it into the graphite yttrium adding device, remove the charcoal layer on the liquid surface, add the metal yttrium to the bottom of the molten metal, and stir gently in circles to completely melt the metal yttrium. When adding metal ...
Embodiment 2
[0032] The invention provides a process for improving the electrical conductivity of copper or copper alloy, comprising:
[0033] 1), take copper-chromium alloy raw material, and record;
[0034] 2), melt the raw materials weighed, and complete the melting of the raw materials;
[0035] The raw material is roasted with charcoal, the roasting voltage is 390V, and the current is 0.8KA.
[0036] 3), refining the melted raw material, and adding metal yttrium to the raw material according to the mass ratio of metal yttrium to raw material is 0.008%;
[0037] When the temperature of the furnace reaches 1360°C, cut off the power, preheat the furnace head and graphite funnel, and preheat the furnace head 1 to 2 times for 2 to 3 minutes each time. Put it into the graphite yttrium adding device, remove the charcoal layer on the liquid surface, add the metal yttrium to the bottom of the molten metal, and stir gently in circles to completely melt the metal yttrium. When adding metal ytt...
Embodiment 3
[0043] The invention provides a process for improving the electrical conductivity of copper or copper alloy, comprising:
[0044] 1), take copper plate raw material, and record;
[0045] 2), melt the raw materials weighed, and complete the melting of the raw materials;
[0046] The raw material is roasted with charcoal, the roasting voltage is 380V, and the current is 0.9KA.
[0047] 3), refining the melted raw material, and adding metal yttrium to the raw material according to the mass ratio of metal yttrium to raw material is 0.009%;
[0048] When the temperature of the furnace reaches 1200°C, turn off the power, preheat the furnace head and graphite funnel, and preheat the furnace head 1 to 2 times for 2 to 3 minutes each time. Put it into the graphite yttrium adding device, remove the charcoal layer on the liquid surface, add the metal yttrium to the bottom of the molten metal, and stir gently in circles to completely melt the metal yttrium. When adding metal yttrium and...
