Muindasitiri yemazuva ano inotsvaga kushanda kwepamusoro, kugona kukanda zvinhu zvesimbi kunotungamira zvakananga padenga rechigadzirwa chekupedzisira. Nzira yechinyakare yekukanda zvinhu inoitwa munzvimbo ine mhepo, uye matambudziko akadai sezvigadzirwa zvesimbi zvisina kukwana uye zvinogara kwenguva pfupi akaoma kudzivirira, izvo zvave dambudziko rinotadzisa kugadzirwa kwezvinhu zvesimbi zvepamusoro.

Saka, pane tekinoroji inogona kubvisa zvikanganiso izvi zvakaita sekukanda simbi munzvimbo yemuchadenga here? Mhinduro ndeyekuti hongu - muchina wekukanda unoenderera mberi wevacuum. Uye nzvimbo yekushandisa muchina wekukanda unoenderera mberi wevacuum yakafara zvikuru.

Chiivacuum kuramba vachikanda?

Zvichitaurwa zviri nyore, kukanda simbi inonyunguduka ibasa repamusoro rinoisa simbi yakanyungudutswa mu crystallizer uye rinoburitsa simbi inonyunguduka munzvimbo ine vacuum yakawanda. Rinobatanidza mabhenefiti maviri makuru e "vacuum degassing" uye "continuous molding" kuita chimwe chete:

Nzvimbo yekubvisa tsvina: inobvisa zvachose kusangana pakati pesimbi yakanyungudutswa nemagasi akadai seokisijeni, nitrogen, uye hydrogen, ichideredza zvakanyanya porosity uye oxide inclusions, uye inovandudza kuchena, huwandu, uye hunhu hwemakanika esimbi.

Kuumbwa kunoenderera mberi: Inogadzira zvinhu zvisingakanganiswi kubva kusimbi yemvura kusvika kune yakasimba, ichishanda zvakanaka uye otomatiki, uye inogonawo kuwana zvinhu zvakareba zvisingaperi zvine chimiro chakafanana uye zvemhando yepamusoro.

Kukanganisa maindasitiri api? Munda Wakakura weKushandiswa kweMuchina weVacuum Continuous Casting

Kushandiswa kwechinhu ichi 'chinogadzirwa' kunopfuura nzvimbo yesimbi yechinyakare, kuri kuwedzera simba idzva mumaindasitiri ekugadzira emhando yepamusoro.

1. Zvishandiso zvakakosha uye mafambiro emuchadenga
Mashandisirwo: Iyi ndiyo nzvimbo huru yekurwira varwi vemagetsi vanokanda zvinhu zvinogara zvichishandiswa. Inoshandiswa pakukanda zvinhu zvine hutsanana hwakanyanya sema alloys anodziya zvakanyanya, titanium alloys, uye alloys dzakanyatsonaka. Zvinhu izvi zvakakosha pakugadzira mablades einjini dzendege, zvikamu zveinjini dzeroketi, uye zvikamu zvechivakwa chemuchadenga.
Kukosha: Simba guru rekuneta uye kugadzikana pakupisa kwakanyanya zvinoita kuti ndege igare yakachengeteka uye yakavimbika munzvimbo dzakaoma.

2. Zvigadzirwa zvekurapa zvepamusoro
Mashandisirwo: Inoshandiswa kugadzira mabhiri esimbi anoenderana nehupenyu akadai sema alloy etitanium ekurapa (akadai seTi-6Al-4V) uye ma alloy e cobalt chromium.
Kukosha: Chipfuko chakagadzirwa chakachena uye hachina tsvina, zvichidzivirira ngura kana allergy yezvinoiswa mumuviri wemunhu. Panguva imwe chete, hunhu hwayo hwakanaka hwemakanika hunoenderana zvakanyanya nemapfupa evanhu, zvichiita kuti ive sarudzo yakanaka yekugadzira majoini ekugadzira, zvinoiswa mazino, uye screws dzemabhonzo.

3. MaSemiconductors neruzivo rweElectronic
Mashandisirwo: Kugadzirwa kwezvinhu zvemhando yepamusoro zvakaita semhangura isina oxygen, mhangura yakachena, uye mhangura yakasanganiswa nephosphorus. Zvinhu izvi ndizvo zvinoumba hwaro hwekugadzira zvinhu zve semiconductor silicon single crystal growth furnace crucibles, lead frames, uye sputtering targets.
Kukosha: Okisijeni yakaderera zvakanyanya uye kufambisa simba kwakanyanya kunoita kuti simba rekupisa rigare zvakanaka uye kuti magetsi ashande zvakanaka panguva yekugadzira machipisi, zvichikanganisa mashandiro uye goho rechipisi.

4. Kutsvaga nekugadzira zvinhu zvitsva
Mashandisirwo: Masangano makuru ekutsvagisa nemarabhoritari ezvinhu anoshandisa michina midiki yekukanda vacuum continuous casting kugadzira mafomura matsva e alloy, kudzidza maitiro ekusimbisa, uye kuita kugadzirwa kwekuyedza kudiki.
Kukosha: Yakapa nzira huru yekugadzirira "danho rekutanga" rezvinhu zvitsva kubva murabhoritari kusvika pakukura kwemaindasitiri, zvichikurumidzisa kubuda kwezvinhu zvitsva.

Zvinhu zvese zvinogona kuumbwa here? Ndeapi mamodheru anogonaVacuum kuramba vachikanda muchina kugadzira?

"Modhi" yemuchina wekukanda unochinjika wevacuum hairevi matoyi kana zvidhori, asi inoreva chimiro chikuru chechigadzirwa chinogadzirwa zvakananga nacho, kureva kuti, billet yekugadzirisa zvakadzama. Zvichienderana nechimiro uye nzira yekudhirowa yekristaro, inogona kugadzira "mhando" dzakasiyana-siyana:

1. Tsvimbo/Ingot Yakatenderera
Tsananguro: Iyi ndiyo fomu inonyanya kushandiswa, ine chikamu chakatenderera.
Kugadziriswa kunotevera: Inogona kugadziriswazve kuita zvikamu zveshaft, turbine discs, zvigadzirwa zvebar, nezvimwewo kuburikidza ne forging, rolling, turning, nedzimwe nzira.

2. Chigadziko chebhirini/chinongedzo chakatsetseka
Tsananguro: Chikamu chakachinjika chakaita sikweya kana kuti rectangular.
Kugadziriswa kunotevera: kunonyanya kushandiswa pakumonera maplate, zvidimbu, uye mafoil, ndiyo substrate yeganda remuchadenga, mabhodhi ekurapa, uye zvikamu zvemagetsi.

3. Chibato chepombi
Tsananguro: Maburi ane maburi matema anodhonzwa zvakananga uye anokandwa kuburikidza nemakristaro akagadzirwa zvakanaka.
Kugadziriswa kunotevera: Inogona kushandiswa pakudhonza nekudhonza nechando kuti igadzire mapaipi asina musono akanyatsojeka, ayo anoshandiswa muminda yakaita semidziyo yekurapa (yakadai semidziyo yeropa), indasitiri yenyukireya, uye kutakurwa kwemvura kwakakosha.

4. Mapurofayiri akagadzirwa
Tsananguro: Gadzirisa makristaro ane maumbirwo akasiyana-siyana zvichienderana nezvinodiwa nevatengi, kuitira kuti ugadzire mabhiritsi ari pedyo nechimiro chekupedzisira chechigadzirwa panguva imwe chete.
Kugadziriswa kunotevera: Izvi zvinoderedza zvakanyanya huwandu hwekugadzirisa kwemuchina kunotevera, zvinochengetedza mari yezvinhu, uye zvakakodzera kugadzirwa kwezvinhu zvakawanda zvine zvikamu zvakasiyana, zvakaita semaprofiles, maburi enzira dzechitima, nezvimwewo.

Muchina wekukanda unoenderera mberi wevacuum hausisiri mudziyo unodhura usingawanikwe, asi ndeimwe yemidziyo mikuru iri kusimudzira indasitiri yekugadzira yepamusoro-soro. Unodzivirira kuchena kwesimbi ne "vacuum" uye unotsanangura kugadzirwa kwakanaka ne "kuenderera mberi". Mukutsvaga kushanda kwezvinhu kwanhasi, kusarudza tekinoroji yekukanda inoenderera mberi yevacuum zvinoreva kusarudza mhando yakavimbika, kushanda kwepamusoro, uye ramangwana rine makwikwi.
Kana vamwe vachiri kunetseka nezvikanganiso zvezvinhu, unogona kutogadzira chipingamupinyi chako chetekinoroji panguva imwe chete.
