C2680 Brass Tube, Kulemera kopepuka, kukhathamiritsa kwabwino kwamafuta, mphamvu yotsika kwambiri ya kutentha.Nthawi zambiri amagwiritsidwa ntchito popanga zida zotengera kutentha (monga condenser, etc.).Amagwiritsidwanso ntchito popanga mapaipi otsika kutentha pazida zopangira mpweya.Chitoliro chaching'ono chamkuwa nthawi zambiri chimagwiritsidwa ntchito potumiza madzi oponderezedwa (monga makina opaka mafuta, makina othamanga amafuta, ndi zina zotero) ndipo amagwiritsidwa ntchito ngati chubu chachitsulo, ndi zina zotero. Machubu amkuwa ndi amphamvu komanso osagwira dzimbiri.
Makamaka ali ndi ubwino zotsatirazi: mkuwa chubu zolimba kapangidwe, osati zosavuta dzimbiri, ndi kukana kutentha, mkulu kuthamanga kukana, angagwiritsidwe ntchito zosiyanasiyana osati mkuwa mtundu chilengedwe.Ndipo yerekezerani ndi chubu chamkuwa, kuperewera kwa zinthu zina zambiri za chitoliro kumawonekera, mwachitsanzo, m'mbuyomo nyumbayi imagwiritsa ntchito chubu chachitsulo cholimba kwambiri, dzimbiri lake ndi losavuta kwambiri, nthawi yogwiritsira ntchito siitali imatha kuwoneka tsitsi lachipopi lamadzi lachikaso, likucheperachepera. dikirani vuto.Palinso zipangizo mu mkulu kutentha mphamvu mwamsanga kuchepetsa, pamene ntchito mipope madzi otentha adzabala zosatetezeka zobisika zoopsa.Koma chifukwa chakuti mkuwa uli ndi malo osungunuka a madigiri 1,083, kutentha kwa madzi otentha kumakhala ndi zotsatira zochepa pa machubu amkuwa.Machubu amkuwa wamba amaphatikizapo chubu chamkuwa chamagetsi, chubu chamkuwa cha firiji, chubu chamkuwa chothamanga kwambiri, chubu chamkuwa chopanda dzimbiri, chubu chamkuwa cholumikizira, chubu chamkuwa chamadzi, chubu chamkuwa chamagetsi, chubu chamagetsi chamagetsi ndi chubu chamkuwa cha mafakitale.
Mbiri yachitukuko
Pakalipano, mankhwala oyambirira a mkuwa omwe amapezeka padziko lapansi makamaka akumadzulo kwa Asia, monga dera la Iraq la Zawei Chemi, anapeza zokongoletsera zamkuwa, zaka za 10,000 BC mpaka 9,000 BC;Zokongoletsera zamkuwa zapezekanso ku ali Kashi kumadzulo kwa Iran, kuyambira 9,000 mpaka 7,000 BC;Singano zamkuwa ndi ma cones zapezeka pa Site of Chayoni kum'mwera kwa Turkey, kuyambira cha m'ma 8,000 BC.Zogulitsa zamkuwazi ndizinthu zachilengedwe zofiira zamkuwa, osati kudzera mumkuwa wosungunula.
Kuyambira pakugwiritsa ntchito mkuwa weniweni, kusungunula miyala yamkuwa mpaka mkuwa woyengedwa bwino, kusungunula mkuwa, anthu akhala akufufuza kwanthawi yayitali, ngati dziko lamatsenga lamkuwa kuti amange ngalande yonyezimira pang'onopang'ono.
Kusungunula mkuwa koyambirira kwambiri padziko lonse lapansi kunapezeka ku Shaanxi, China.Mu 1973, mbale yamkuwa ya semicircular ndi chubu chamkuwa chinapezeka pamalo a Jiangzhai Cultural ku Lintong, m'chigawo cha Shaanxi, cha m'ma 4700 BC.Worth kusonyeza kuti gwero kuwala mu Shanghai posachedwapa, ntchito X-ray fulorosenti kupanga sikani kusanthula, anapeza kuti nthaka zili m'madera osiyanasiyana a mkuwa magawo ginger wodula bwino lomwe kusiyana kwambiri, ndi kutsogolera anamwazikana mfundo yogawa, makhalidwe ake ndi kuchepetsa olimba boma. njira mkuwa ndi chimodzimodzi, motero kutsimikizira makolo anatulukira ntchito zachilengedwe zitsulo ndi zitsulo kuponyera ntchito pamene otentha kuwotcha kapena olimba kuchepetsa smelting zitsulo.

Mkuwa wotsogolera
Mtovu kwenikweni susungunuka mu mkuwa ndipo umagawira malire a tirigu ngati tinthu taulere.Mkuwa wotsogolera uli ndi α ndi (α + β) malinga ndi kapangidwe kake.Mkuwa wotsogolera wa alpha ukhoza kukhala wopunduka wozizira kapena wotentha kwambiri chifukwa cha kuwopsa kwa lead ndi kutsika kwa pulasitiki pa kutentha kwakukulu.(α + β) mkuwa wotsogolera uli ndi ductility wabwino pa kutentha kwakukulu ndipo ukhoza kupangidwa.
Tin mkuwa
Kuphatikizika kwa malata mumkuwa kumatha kuwongolera kukana kwa kutentha kwa aloyi, makamaka kuthekera kopititsa patsogolo kukana kwa dzimbiri kwa madzi a m'nyanja, motero mkuwa wa malata umatchedwa "navy brass".
malata akhoza kusungunuka kukhala mkuwa - zochokera olimba njira kulimbitsa yankho.Komabe, ndi kuchuluka kwa malata, padzakhala brittle R gawo (CuZnSn pawiri) mu aloyi, zomwe sizigwirizana ndi mapindikidwe apulasitiki a aloyi, kotero kuti malata omwe ali mumkuwa amakhala pafupifupi 0,5% ~ 1.5%.
Amagwiritsidwa ntchito malata mkuwa hSN70-1, HSN62-1, HSN60-1 ndi zina zotero.Yoyamba ndi α alloy yokhala ndi mapulasitiki apamwamba ndipo imatha kukonzedwa ndi kuzizira komanso kutentha.Mitundu iwiri yotsirizira ya aloyi ili ndi (α + β) mawonekedwe a magawo awiri, ndipo nthawi zambiri kagawo kakang'ono ka R, kutentha kwa pulasitiki sikukwera, kumangowonongeka pansi pa kutentha.
Manganese mkuwa
Manganese ali ndi kusungunuka kwakukulu mu mkuwa wolimba.Mphamvu ndi kukana kwa dzimbiri kwa aloyi kumatha kuwongolera bwino popanda kuchepetsa ductility powonjezera 1% ~ 4% manganese mkuwa.
Mkuwa wa manganese uli ndi (α + β) microstructure ndipo hMN58-2 imagwiritsidwa ntchito kwambiri.Ili ndi ntchito yabwino yopangira makina pansi pazigawo zozizira komanso zotentha.
Chitsulo, mkuwa
Mu mkuwa wachitsulo, chitsulo chimapangidwa ndi tinthu tating'onoting'ono tachitsulo monga ma crystal nuclei kuti tiyenge mbewu ndikuletsa mbewu za recrystallization kuti zisakule, kuti zipititse patsogolo makina ndi ukadaulo wa alloy.Mkuwa wachitsulo muzitsulo zachitsulo nthawi zambiri zimakhala zosakwana 1.5%, kapangidwe kake ndi (α + β), ndi mphamvu zambiri komanso kulimba, pulasitiki ndi yabwino kwambiri kutentha kwambiri, kuzizira kungathenso kupunduka.Mtundu womwe umagwiritsidwa ntchito kwambiri ndi HFE59-1-1.
Siliva ya Nickel
Nickel ndi mkuwa zimatha kupanga njira yokhazikika yokhazikika ndikukulitsa gawo la α kwambiri.Kukana kwa dzimbiri kwa mkuwa mumlengalenga ndi m'madzi am'nyanja kumatha kupitilizidwa powonjezera faifi tambala.Nickel imathanso kuonjezera kutentha kwa mkuwa komanso kulimbikitsa mapangidwe a mbewu zabwino.
Hni65-5 nickel-brass ili ndi gawo limodzi la α, lomwe lili ndi pulasitiki yabwino kutentha kutentha ndipo imatha kupunduka potentha.Komabe, zomwe zili muzodetsa za mtovu ziyenera kuyendetsedwa mosamalitsa, kapena katundu wotentha wa aloyiyo angawonongeke kwambiri.
