Kusanthula mwachidule kwa chithandizo cha kutentha pa beryllium bronze

Beryllium bronze ndi aloyi yolimba kwambiri yomwe imagwiritsa ntchito mphamvu zambiri. Pambuyo pa yankho lolimba komanso kukalamba, mphamvu yake imatha kufika 1250-1500MPa (1250-1500kg). Makhalidwe ake ochizira kutentha ndi awa: imakhala ndi pulasitiki wabwino pambuyo pa chithandizo cha yankho lolimba ndipo imatha kusinthidwa ndi ntchito yozizira. Komabe, ikakalamba, imakhala ndi malire abwino kwambiri otanuka, ndipo kuuma kwake ndi mphamvu zake zimawonjezekanso.

(1) Chithandizo cha beryllium bronze cholimba

Kawirikawiri, kutentha kwa kutentha kwa mankhwala ophera chitsulo ndi pakati pa 780-820℃. Pazinthu zomwe zimagwiritsidwa ntchito ngati zotanuka, 760-780℃ imagwiritsidwa ntchito, makamaka kuti tipewe kuti tinthu tating'onoting'ono tisakhudze mphamvu. Kufanana kwa kutentha kwa ng'anjo yophera chitsulo kuyenera kulamulidwa mosamalitsa mkati mwa ±5°C. Nthawi yogwira nthawi zambiri imatha kuwerengedwa ngati ola limodzi/25mm. Pamene beryllium bronze ikutenthedwa ndi mankhwala olimba mumlengalenga kapena mumlengalenga wothira chitsulo, filimu ya oxide imapangidwa pamwamba. Ngakhale kuti siili ndi mphamvu zambiri pa zinthu zamakina pambuyo polimbitsa ukalamba, idzakhudza moyo wa ntchito ya nkhungu ya chida panthawi yogwira ntchito yozizira. Kuti tipewe oxidation, iyenera kutenthedwa mu uvuni wa vacuum kapena kuwonongeka kwa ammonia, mpweya wopanda mpweya, mpweya wochepetsa kutentha (monga hydrogen, carbon monoxide, ndi zina zotero) kuti ipeze mphamvu yowala yophera chitsulo. Kuphatikiza apo, chisamaliro chiyenera kuperekedwa pakufupikitsa nthawi yosamutsira (panthawi yozimitsa) momwe zingathere, apo ayi zinthu zamakina zikakalamba zidzakhudzidwa. Zipangizo zoonda siziyenera kupitirira masekondi atatu, ndipo zigawo zonse siziyenera kupitirira masekondi asanu. Chozimitsira nthawi zambiri chimagwiritsa ntchito madzi (sikufunikira kutenthetsa). Zachidziwikire, mafuta angagwiritsidwenso ntchito pazinthu zomwe zili ndi mawonekedwe ovuta kuti apewe kusintha.

(2) Chithandizo cha ukalamba cha beryllium bronze

Kutentha kwa ukalamba kwa beryllium bronze kumagwirizana ndi kuchuluka kwa Be. Ma alloy onse okhala ndi zosakwana 2.1% Be ayenera kukhala okalamba. Pa ma alloy okhala ndi Be oposa 1.7%, kutentha kwabwino kwambiri kwa ukalamba ndi 300-330°C, ndipo nthawi yogwira ndi maola 1-3 (kutengera mawonekedwe ndi makulidwe a gawolo). Pa ma alloy a electrode oyenda bwino kwambiri okhala ndi Be osakwana 0.5%, chifukwa cha kuchuluka kwa kusungunuka, kutentha kwabwino kwambiri kwa ukalamba ndi 450-480°C ndipo nthawi yogwira ndi maola 1-3. M'zaka zaposachedwa, ukalamba wa magawo awiri ndi magawo ambiri wapangidwanso, ndiko kuti, ukalamba wa nthawi yochepa pa kutentha kwakukulu kenako kutenthetsa kwa nthawi yayitali kukalamba pa kutentha kochepa. Ubwino wa izi ndikuti magwiridwe antchito amawongoka koma kusintha kwachepa. Pofuna kukonza kulondola kwa beryllium bronze pambuyo pa ukalamba, zida zitha kugwiritsidwa ntchito pokalamba, ndipo nthawi zina magawo awiri osiyana a chithandizo cha ukalamba angagwiritsidwe ntchito.

(3) Chithandizo chochepetsa kupsinjika kwa beryllium bronze

Kutentha kwa beryllium bronze komwe kumathandizira kuchepetsa kupsinjika ndi 150-200℃ ndipo nthawi yogwira ntchito ndi maola 1-1.5. Ingagwiritsidwe ntchito kuthetsa kupsinjika kotsalira komwe kumachitika chifukwa cha kudula chitsulo, kuwongola, kupanga kozizira, ndi zina zotero, ndikukhazikitsa mawonekedwe ndi kulondola kwa magawo panthawi yogwiritsidwa ntchito kwa nthawi yayitali.

Mitundu ya mkuwa ya beryllium bronze/beryllium yomwe imagwiritsidwa ntchito kwambiri

Jindalai Steel Group ili ndi mphamvu yopereka zinthu zotumizira nthawi yake komanso kukonza zinthu zodulira ndi kudula zomwe zimafunika kuti zitsimikizire kuti zitha kupatsa ogwiritsa ntchito zinthu zachitsulo zoyenera molondola komanso mwachangu. Kampaniyo ili ndi zinthu zambiri zopangidwa ndi mkuwa monga mkuwa, mkuwa wopanda mpweya, mkuwa wa beryllium, mkuwa, mkuwa, mkuwa woyera, mkuwa wa chromium zirconium, mkuwa wa tungsten, ndi zina zotero chaka chonse. Zinthu zomwe zimaperekedwa zikuphatikizapo ndodo zamkuwa, mbale zamkuwa, machubu amkuwa, zingwe zamkuwa, mawaya amkuwa, waya wamkuwa, waya wamkuwa, mzere wamkuwa, bar wamkuwa, chipika cha mkuwa, ndodo ya hexagonal, chubu cha sikweya, keke yozungulira, ndi zina zotero, ndipo zipangizo zosiyanasiyana zomwe sizili zachizolowezi zimatha kusinthidwa.
