Kaʻina Hana Hana Copper Beryllium
Hoʻokaʻawale ʻia ke kaʻina hana o ka beryllium copper i ʻehā mau ʻanuʻu: ʻo ka hana ʻana o ka beryllium-copper master alloy e ka carbothermal reduction method, ka hoʻoheheʻe ʻana o ka beryllium copper alloy, ka ingot o ke keleawe keleawe a me ka hana ʻana o ka beryllium copper alloy plate, strip and strip.
ʻO ka hana ʻana o ka beryllium-copper master alloys e ka carbothermal reduction e pili ana i ka hoʻemi pololei ʻana o ka beryllium i ka beryllium oxide me ke kalapona i loko o ke keleawe hoʻoheheʻe ʻia, a ukali ʻia e ka alloying i ke keleawe.ʻO ka hana ʻana o ka beryllium-copper master alloy e ka carbothermic reduction i ka ʻoihana e hana ʻia i loko o kahi umu ahi uila.Hoʻokomo ʻia ka umu uila i loko o kahi pahu i hoʻopaʻa ʻia.Hoʻohana ka mea hoʻohana i ka pale kinoea.Hoʻohui ʻia ka % o ka pauda kalapona i loko o ka wili pōleʻa a me ka lepo, a laila hoʻokomo ʻia kahi papa keleawe, kahi ʻāpana beryllium oxide a me ka hui ʻana o ka pauka kalapona i loko o ka umu ahi arc uila i nā pūʻulu, hoʻoikaika a hoʻoheheʻe ʻia.Ke hoʻoluʻu i 950 degere Celsius - 1000 degere Celsius, ʻo ka inoa alloy beryllium carbide, carbon, a me ke koena pauka e lana, slag, a laila hoʻolei ʻia i loko o 2.25 kg a i ʻole 5 kg ingots ma 950 degere Celsius.
ʻO ka uku i hoʻohana ʻia i ka hoʻoheheʻe ʻana i ka beryllium copper alloy me ka metala hou, ka ʻōpala, ka uku hoʻoheheʻe lua a me ka alloy master.
Hoʻohana maʻamau ka Beryllium i ka beryllium-copper master alloy (me ka beryllium 4%);Hoʻohana ka nickel i kekahi manawa metala hou, ʻo ia hoʻi, electrolytic nickel, akā ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka nickel-copper master alloy (loaʻa ka 20% ​​nickel);Hoʻohana ka cobalt i ka cobalt-copper master alloy (Cobalt 5.5%), a hoʻohana pololei kekahi i ka cobalt maʻemaʻe;Hoʻohui ʻia ka titanium e ka titanium-copper master alloy (loaʻa ka 15% titanium, a ʻo kekahi pū kekahi he 27.4% titanium), a hoʻohui pololei kekahi i ka titanium sponge;ʻO ka magnesium ka magnesium- Ua hoʻohui ʻia ke keleawe master alloy (loaʻa ka 35.7% magnesium).
