Kusanthula mwachidule kwa chithandizo cha kutentha pa beryllium bronze

Beryllium bronze ndi aloyi wosunthika kwambiri wamvula. Pambuyo pa njira yolimba ndi chithandizo cha ukalamba, mphamvu imatha kufika 1250-1500MPa (1250-1500kg). Makhalidwe ake ochizira kutentha ndi awa: ali ndi pulasitiki wabwino pambuyo pa chithandizo cholimba cha yankho ndipo amatha kupundutsidwa ndi kuzizira. Komabe, pambuyo pa chithandizo chaukalamba, chimakhala ndi malire abwino kwambiri otanuka, ndipo kuuma kwake ndi mphamvu zake zimakhalanso bwino.

(1) Chithandizo chokhazikika cha beryllium bronze

Nthawi zambiri, kutentha kwa kutentha kwa chithandizo chamankhwala kumakhala pakati pa 780-820 ℃. Pazinthu zomwe zimagwiritsidwa ntchito ngati zotanuka, 760-780 ℃ imagwiritsidwa ntchito, makamaka kuteteza njere zolimba kuti zisakhudze mphamvu. Kutentha kofanana kwa ng'anjo yochizira yankho kuyenera kuyendetsedwa mosamalitsa mkati mwa ± 5 ° C. Nthawi yogwira imatha kuwerengedwa ngati 1 ora/25mm. Pamene mkuwa wa beryllium umakhala ndi njira yolimba yotenthetsera mankhwala mumlengalenga kapena oxidizing atmosphere, filimu ya oxide idzapangidwa pamwamba. Ngakhale ali ndi zotsatira zochepa pa mawotchi katundu pambuyo zaka kulimbitsa, izo zimakhudza moyo utumiki wa nkhungu chida pa ntchito ozizira. Kupewa makutidwe ndi okosijeni, ayenera kutenthedwa mu ng'anjo zingalowe kapena kuwonongeka ammonia, inert mpweya, kuchepetsa mpweya (monga haidrojeni, carbon monoxide, etc.) kupeza kuwala kutentha zotsatira. Kuphatikiza apo, chidwi chiyenera kulipidwa pakufupikitsa nthawi yosinthira (panthawi yozimitsa) momwe mungathere, apo ayi zida zamakina pambuyo pa ukalamba zidzakhudzidwa. Zida zoonda sizingadutse masekondi atatu, ndipo zigawo zonse sizidzapitilira masekondi 5. Njira yozimitsira nthawi zambiri imagwiritsa ntchito madzi (palibe kutentha kofunikira). Zachidziwikire, mafuta atha kugwiritsidwanso ntchito pazigawo zokhala ndi mawonekedwe ovuta kuti apewe kupunduka.

(2) Chithandizo chaukalamba cha beryllium bronze

Kutentha kokalamba kwa beryllium bronze kumagwirizana ndi Khalani okhutira. Ma alloys onse okhala ndi zosakwana 2.1% Ayenera kukhala okalamba. Kwa ma alloys okhala ndi Be wamkulu kuposa 1.7%, kutentha koyenera kukalamba ndi 300-330 ° C, ndipo nthawi yogwira ndi maola 1-3 (malingana ndi mawonekedwe ndi makulidwe a gawolo). Kwa ma aloyi a electrode conductive kwambiri okhala ndi Khalani osachepera 0.5%, chifukwa cha kuchuluka kwa kusungunuka, kutentha koyenera kukalamba ndi 450-480 ° C ndipo nthawi yogwira ndi maola 1-3. M'zaka zaposachedwa, kukalamba kwapawiri komanso kwamitundu yambiri kumapangidwanso, ndiko kuti, kukalamba kwakanthawi kochepa pa kutentha kwakukulu ndiyeno kukalamba kwanthawi yayitali kutsekereza kutentha pang'ono. Ubwino wa izi ndikuti magwiridwe antchito amawongoleredwa koma deformation imachepetsedwa. Pofuna kuwongolera kulondola kwa mkuwa wa beryllium pambuyo pa ukalamba, zosintha zimatha kugwiritsidwa ntchito kukalamba, ndipo nthawi zina magawo awiri osiyana a chithandizo cha ukalamba angagwiritsidwe ntchito.

(3) Chithandizo cha kupsinjika kwa beryllium bronze

Kutentha kochepetsera nkhawa kwa bronze wa beryllium ndi 150-200 ℃ ndipo nthawi yogwira ndi maola 1-1.5. Itha kugwiritsidwa ntchito kuthetsa kupsinjika kotsalira komwe kumachitika chifukwa cha kudula zitsulo, kuwongola, kupanga kuzizira, ndi zina zambiri, ndikukhazikitsa mawonekedwe ndi kulondola kwa magawo pakugwiritsa ntchito nthawi yayitali.

Nthawi zambiri amagwiritsidwa ntchito beryllium bronze / beryllium mkuwa

Gulu la Jindalai Steel lili ndi kuthekera kopereka nthawi yake komanso kugubuduza ndi kudula pofunikira kuti zitsimikizire kuti zitha kupatsa ogwiritsa ntchito zitsulo zoyenerera molondola komanso mwachangu. Kampaniyo imasunga zinthu zambiri zamkuwa zamkuwa monga mkuwa, mkuwa wopanda okosijeni, mkuwa wa beryllium, mkuwa, mkuwa, mkuwa woyera, mkuwa wa chromium zirconium, mkuwa wa tungsten, etc. chaka chonse. Zinthu zomwe zimaperekedwa zimaphatikizapo ndodo zamkuwa, mbale zamkuwa, machubu amkuwa, zingwe zamkuwa, mawaya amkuwa, Waya wamkuwa, mzere wamkuwa, mipiringidzo yamkuwa, chipika chamkuwa, ndodo ya hexagonal, chubu lalikulu, keke yozungulira, etc. kukhala makonda.
