Solder, sechinhu chakakosha chekubatanidza zvinhu munzvimbo dzakawanda dzakadai semagetsi, mota, aerospace, nezvimwewo, kunaka kwayo uye kuita kwayo zvinokanganisa kuvimbika uye kugadzikana kwezvigadzirwa. Nekuenderera mberi kwekufambira mberi kwetekinoroji, izvo zvinodikanwa zvekuchena, microstructure, uye kuita kwe solder zviri kuramba zvichikwira. Sechishandiso chepamusoro chesimbi yekukanda, iyo vacuum yakatwasuka inoramba ichikanda muchina yakwezva kutarisisa zvishoma nezvishoma muindasitiri yekutengesa, ichipa mhinduro inoshanda yemhando yepamusoro yekugadzira solder.

1,Kushanda musimboti wevacuum yakatwasuka inoenderera ichikandira muchina

Iyo vacuum yakatwasuka inoenderera yekukanda muchina inonyanya kuumbwa nechoto, crystallizer, billet kudhonza mudziyo, vacuum system, uye zvimwe zvikamu. Chekutanga, isa iyo solder muchoto chinonyunguduka woipisa kuti isvike tembiricha yemvura yakakodzera. Zvadaro, nzvimbo yekukanda inobviswa kune imwe nhanho kuburikidza ne-vacuum system kuderedza kusanganiswa kwegasi tsvina. Pasi pechiito chegiravhiti uye kumanikidzwa kwekunze, solder yemvura inoyerera ichipinda mukristaro yakaiswa yakachinjika, inotonhodzwa nemvura inotenderera kuti igosimba zvishoma nezvishoma uye kupenya pamadziro emukati, ichigadzira goko. Nekunonoka kudhonza kwechishandiso chekukanda, nyowani yemvura solder inoramba ichizadzikiswa mucrystallizer, uye yakaomeswa solder goko rinoramba richiburitswa kunze, nokudaro richiwana inoenderera yekukanda maitiro.

2,Zvakanakira Vacuum Horizontal Continuous Casting Machine

(1）Kuvandudza solder kuchena

Kukanda munzvimbo yevacuum kunogona kudzivirira kusvibiswa kwegasi seokisijeni uye nitrogen kubva pakupinda mune solder, kuderedza kuumbwa kwe oxide inclusions uye pores, kuvandudza zvakanyanya kuchena kwe solder, uye kuwedzera kunyorova kwayo uye kuyerera panguva yekugadzira, nekudaro kuvandudza. kunaka kwekubatanidzwa kwe welded.

(2）Kuvandudza microstructure ye solder zvinhu

Munguva yevacuum yakatwasuka inoramba ichikandwa, chiyero chekuomarara chemvura solder chakafanana, uye mwero wekutonhora unodzoreka, izvo zvinoita kuti paumbwe yunifomu uye yakanaka zviyo chimiro uye kuderedza kusarurana kwezviitiko. Iyi yunifomu yehurongwa yehurongwa inoita kuti michina ye solder igadzikane, senge simba rekusimba uye kurebesa, izvo zvinovandudzwa uye kusangana nezvimwe zvinodikanwa zvekushandisa zvekushandisa solder.

(3）Kubudirira kuenderera mberi kugadzira

Kuenzaniswa nemaitiro echinyakare ekukanda, vacuum yakatwasuka inoenderera mberi yekukanda michina inogona kuwana inoenderera uye isingakanganiswe kugadzirwa, ichivandudza zvakanyanya kugadzirwa. Panguva imwecheteyo, ine yakakwira dhigirii ye otomatiki, ichidzikisa nhanho dzekushanda kwemaoko, kudzikisira kusimba kwevashandi uye mutengo wekugadzira, uye kuita kuti maitiro ekugadzira agadzikane uye akavimbika, ayo anobatsira mukuenderana kutonga kwemhando yechigadzirwa.

(4）Deredza marara

Nekuda kwekuenderera mberi kwekukanda maitiro uye kutonga kwakaringana kwehukuru uye chimiro chebillet, zvichienzaniswa nedzimwe nzira dzekukanda, inogona kunyatso shandisa zvigadzirwa, kuderedza tsvina yemidziyo inokonzerwa nekucheka, machining mvumo, nezvimwewo, kuvandudza mwero wekushandisa. zvigadzirwa, uye kuderedza mari yekugadzira.

3,Yakananga maapplication mune solder indasitiri

(1）Nzira yekugadzira

Mukugadzira solder, danho rekutanga nderekunyatso kusanganisa zvinodiwa solder uye kuwedzera zvakagadzirirwa mbishi kuchoto chevacuum horizontal inoenderera mberi yekukanda muchina. Tanga iyo vacuum system, kuderedza kudzvinyirira mukati mechoto kusvika kune yakakodzera vacuum level, kazhinji pakati pemakumi epascals nemazana epascals, ipapo kupisa uye kunyungudutsa solder uye kuchengetedza kugadzikana kwakagadzikana. Rongedza kumhanya kwekukanda uye vhoriyamu yemvura inotonhorera yekristallizer kuti ive nechokwadi chekuti solder yemvura inoomesa zvakafanana mukristaro uye inoramba ichiburitswa kunze, ichigadzira imwe yakatarwa ye solder billet. Iyo blank inogadziriswa kuburikidza neanotevera rolling, kudhirowa uye mamwe matanho ekugadzirisa kuti abudise akasiyana maumbirwo uye maratidziro ezvigadzirwa zvekutengesa, senge welding wire, welding strip, solder paste, nezvimwe, kusangana nezvinodiwa zvekushongedza zveminda dzakasiyana.

(2）Kuvandudza kunaka kwezvinhu zvekutengesa

Kutora Sn Ag Cu lead-yemahara solder inowanzoshandiswa muindasitiri yemagetsi semuenzaniso, kana ichigadzirwa uchishandisa vacuum yakatwasuka inoramba ichikanda muchina, iyo okisijeni yemukati mune solder inogona kudzorwa zvakanyanya padanho rakaderera, kudzivirira tsvina yakaita seti slag. inokonzerwa neoxidation uye kuvandudza kushandiswa kunobudirira kwehuwandu hwekutengesa. Panguva imwecheteyo, yunifomu yehurongwa inogonesa solder kuzadza zvirinani madiki solder majoini mapeji panguva yeiyo micro soldering process yemagetsi zvikamu, kuderedza kukanganiswa kwewelding senge virtual soldering uye bridging, nekuvandudza kuvimbika kwewelding uye kushanda kwemagetsi kwezvigadzirwa zvemagetsi.

Mukuita brazing yeindasitiri yemotokari, kune yakakwirira-simba aruminiyamu based solder, solder inogadzirwa nevacuum yakatwasuka inoenderera ichikandira muchina ine simba riri nani uye kusagadzikana kwekuora. Chimiro chayo chezviyo chakafanana chinovimbisa kugadzikana kwemutengesi panguva yekushisa kwepamusoro-soro, iyo inogona kubatanidza zvakasimba zvikamu zvemotokari uye kuvandudza kushanda kwese uye hupenyu hwebasa rezvikamu zvemotokari.

(3）Mienzaniso yekushandisa

Bhizinesi rinozivikanwa rekugadzira solder rakaunza avacuum level inoenderera mberi yekukanda muchina, iyo yakawedzera kuchena kwetini yayo inotungamira solder zvigadzirwa kubva ku98% kusvika pamusoro pe99.5%, uye zvakanyanya kuderedza zvirimo zve oxide inclusions. Mukushandiswa kwewelding yemabhodhi emagetsi edunhu, mwero wekutadza kwewelding wadzikira kubva pa5% kusvika pasi pe1%, zvichivandudza zvakanyanya kukwikwidza kwemusika wechigadzirwa. Panguva imwecheteyo, nekuda kwekuvandudzwa kwekuita basa rekugadzira uye kudzikiswa kwemarara, mutengo wekugadzira webhizinesi wakadzikiswa ne15%, kuwana zvakanaka zvehupfumi uye zvemagariro.

4,Tarisiro dzebudiriro

Nekukurumidza kusimudzira maindasitiri akadai semagetsi, simba idzva, uye yepamusoro-yekupedzisira michina yekugadzira, kunaka uye kuita zvinodiwa zvezvinhu zvekutengesa zvicharamba zvichiwedzera. Iyo vacuum yakatwasuka inoenderera mberi yekukanda muchina ine yakafara tarisiro yekushandisa muindasitiri yekutengesa nekuda kwemabhenefiti ayo akasiyana. Mune ramangwana, nekuenderera mberi kwekufambira mberi kwehunyanzvi hwekugadzira michina, iyo vacuum system ichave inoshanda uye yakagadzikana, dhigirii rekutonga otomatiki richawedzera kuvandudzwa, uye yakanyatso gadziriso dhizaini yekutonga inogona kuwanikwa, ichigadzira yakakwirira mhando uye yakawedzera munhu solder. zvigadzirwa. Zvichakadaro, nekuwedzera kuomarara kwezvakatipoteredza zvinodiwa, zvakanakira vacuum level inoenderera mberi yekukanda michina mukuderedza kushandiswa kwesimba uye kuburitsa zvinosvibisa zvinozoita kuti ive yakakosha kutsigira tekinoroji yekusimudzira indasitiri yevatengesi.

5, Mhedziso

Iko kushandiswa kwevacuum horizontal inoenderera mberi yekukanda muchina muindasitiri yekutengesa inopa vimbiso yakasimba yemhando yepamusoro uye yepamusoro-soro kugadzirwa kwe solder. Nekuvandudza kuchena kwe solder, kusimudzira hurongwa hwesangano, kuwana kuenderera mberi kwekugadzirwa, uye kuderedza mitengo, kuwedzera kwekuda kwekutengesa muindasitiri yemazuva ano kwakazadzikiswa. Nekuenderera mberi nekuvandudzika kwehunyanzvi hwetekinoroji, kushandiswa kwayo muindasitiri yekutengesa kuchawedzera kuwanda uye kwakadzama, kusimudzira kusimudzira kweindasitiri yekutengesa kune yemhando yepamusoro, kuita kwepamusoro, uye girinhi kuchengetedzwa kwezvakatipoteredza, zvichipa mamwe emhando yepamusoro uye akavimbika. zvekubatanidza zvemaindasitiri mazhinji anovimba nekubatanidza solder, uye kusimudzira tekinoroji kukwidziridzwa uye kufambira mberi kweiyo indasitiri cheni.

Mune ramangwana rekuvandudza indasitiri yevatengesi, mabhizinesi anofanirwa kuziva zvizere kugona uye kukosha kwevacuum level inoenderera mberi yekukanda michina, kusuma nekushandisa iyi tekinoroji yepamusoro, kusimbisa hunyanzvi hwetekinoroji uye kugadzirisa mashandiro, kuramba vachiwedzera kukwikwidza kwavo kwemusika, uye kusimudzira pamwe chete mutengesi. indasitiri kuenda kune imwe nhanho yebudiriro.
