Abstract
Sposób wytwarzania prętów ze stopu miedzi z magnezem, polegający na poddaniu składników stopowych syntezie metalurgicznej i procesowi odlewania ciągłego, a następnie chłodzeniu, charakteryzuje się tym, że granulat miedziany o czystości co najmniej 99,9% topi się w tyglu grafitowym pieca indukcyjnego w temperaturze 1200°C - 1250°C. Następnie uzyskany ciekły metal przysypuje się warstwą ochronną o grubości 0,5 - 4 cm w postaci posypki grafitowej o uziarnieniu do 0,5 cm, po czym magnez o czystości co najmniej 99,9% owinięty blachą miedzianą o grubości 0,5 - 1 mm, zanurza się w ciekłym metalu pod posypką grafitową i wtapia go przez 10 - 20 minut. Całkowita zawartość magnezu wynosi 2% - 4% wag., a miedzi 96% - 98% wag. Następnie odlewa się w procesie ciągłym pręty, z wykorzystaniem krystalizatora grafitowego, przy prędkości odlewania 100 - 200 mm/min. Pręty chłodzi się w procesie dwuetapowym: w pierwszym etapie do temperatury 380°C - 400°C, z prędkością chłodzenia 15-25°C/s, a w drugim etapie do osiągnięcia temperatury końcowej 120°C - 250°C z prędkością chłodzenia 5-15°C/s.A method for manufacturing rods from a copper-magnesium alloy, which involves subjecting the alloying components to metallurgical synthesis and continuous casting followed by cooling, is characterized in that copper granulate of at least 99.9% purity is melted in a graphite crucible of an induction furnace at a temperature of 1200°C - 1250°C. The resulting liquid metal is then covered with a 0.5 - 4 cm thick protective layer of graphite with a grain size of up to 0.5 cm, after which magnesium of at least 99.9% purity, wrapped in a 0.5 - 1 mm thick copper sheet, is immersed in the liquid metal under the graphite coating and melted for 10 - 20 minutes. The total magnesium content is 2% - 4% by weight, and the total copper content is 96% - 98% by weight. The rods are then continuously cast using a graphite crystallizer at a casting speed of 100-200 mm/min. The rods are cooled in a two-stage process: in the first stage to a temperature of 380°C-400°C, at a cooling rate of 15-25°C/s, and in the second stage to a final temperature of 120°C-250°C, at a cooling rate of 5-15°C/s.
