Embodiment 1
[0031] Micro-alloyed tin-bronze alloy preparation method of the present invention, concrete steps are:
[0032] 1. Alloy melting: non-vacuum induction furnace is used for melting. Put the electrolytic copper into the smelting furnace, heat until the melt is completely melted, add a covering agent to keep it warm, after degassing and impurity removal, cover with burning charcoal, add the dried Cu-P master alloy and Sn, and stir well After standing;
[0033] 2. Microalloying treatment: add 0.2% cobalt refiner to the refined melt, and perform microalloying treatment at a high temperature of 1240-1300 ° C; The smelting temperature is consistent, and the microalloying treatment temperature refers to the temperature used in the existing alloy smelting;
[0034] 3. Alloy casting: Ingot casting of microalloying melt, the casting temperature is 1150-1250°C slightly lower than the temperature used in the above microalloying treatment, under the action of cooling conditions and refiner...
