Embodiment 1
[0018] Put the electrolytic copper into the smelting device for melting. The melting temperature is 1150℃~1160℃. Cu-P alloy containing 50% P element, Cu-La alloy containing 30% La element and Cu-B alloy containing 20% B element are added to the copper melt and stirred until melting, electrolytic copper, Cu-P, Cu-La The weight and number ratio of Cu-B and Cu-B is 2:1:0.5:0.5, the melt is left to stand, the slag is discharged, and poured into a mold to form an intermediate alloy Cu-10P-3La-2B, which is broken into small pieces; using 100% Red miscellaneous copper is used as raw material, the ingot is prepared by the horizontal continuous casting method, and the T2 red copper bar is produced by the extrusion method; After refining the agent, fully stir the melt, remove slag and let it stand for 15-30 minutes before pouring. In the continuous casting process, the intermediate alloy fragments are regularly added to the melt in the heat-retaining casting furnace, the amount of ad...
Embodiment 2
[0020] Put the electrolytic copper into the smelting device for melting. The melting temperature is 1150℃~1160℃. Cu-P alloy containing 48% P element, Cu-La alloy containing 32% La element and Cu-B alloy containing 20% B element are added to the copper melt and stirred until melting, electrolytic copper, Cu-P, Cu-La The ratio of parts by weight to Cu-B is 1:1:0.25:0.2, the melt is left to stand, slag is discharged, and poured into a mold to form an intermediate alloy Cu-12P-2La-1B, which is broken into small pieces; using 100% Red miscellaneous copper is used as raw material, the ingot is prepared by the horizontal continuous casting method, and the T2 red copper bar is produced by the extrusion method; After refining the agent, fully stir the melt, remove slag and let it stand for 15-30 minutes before pouring. During the continuous casting process, the intermediate alloy fragments are regularly added to the melt in the heat-retaining casting furnace, the amount of addition ...
