Inoramba ichikanda Michina
Iyo basa musimboti weyakajairika mhando inoenderera mberi yekukanda michina yakavakirwa pamazano akafanana seyedu vacuum pressure yekukanda michina. Panzvimbo pekuzadza iyo mvura muflask unogona kugadzira / kudhirowa pepa, waya, tsvimbo, kana chubhu uchishandisa graphite mold. Zvese izvi zvinoitika pasina mabhuru emhepo kana kupera porosity. Iyo vacuum uye yakakwira vacuum inoenderera yekukanda michina inonyanya kushandiswa kugadzira yakakwirira-yekupedzisira mhando waya senge bonding waya, semiconductor, aerospace munda.
Chii chinonzi continuous casting, ndechei, chii chakanakira?
Iyo inoenderera mberi yekukanda maitiro inzira inoshanda kwazvo yekugadzira zvigadzirwa zvakapera semi-apera senge mabara, profiles, slabs, mitsetse uye machubhu akagadzirwa kubva kugoridhe, sirivheri uye asiri-ferrous simbi semhangura, aluminium uye alloys.
Kunyangwe paine akasiyana anoenderera mberi ekukanda maitiro, hapana mutsauko wakakosha mukukanda goridhe, sirivha, mhangura kana alloys. Musiyano wakakosha ndiwo tembiricha yekukanda iyo inotangira pa1000 ° C kana iri sirivheri kana mhangura kusvika 1100 ° C kana iri goridhe kana mamwe maalloys. Simbi yakanyungudutswa inoramba ichikandwa mumudziyo wekuchengetera unodaidzwa kuti ladle uye inoyerera ichibva ipapo ichienda kune yakatwasuka kana yakachinjika yekukanda mold ine magumo akashama. Ichiri kuyerera nepakati peforoma, iyo yakatonhodzwa necrystallizer, iyo mvura yakawanda inotora chimiro cheforoma, inotanga kusimba pamusoro payo uye ichisiya mold iri semi-yakasimba tambo. Panguva imwe chete, kunyungudika kutsva kunogara kuchipihwa kune mold pamwero wakafanana kuti uenderane netambo inosimbisa ichisiya mold. Iyo tambo inowedzera kutonhodzwa nenzira yemvura yekupfapfaidza system. Kuburikidza nekushandiswa kwekutonhora kwakawedzera zvinokwanisika kuwedzera kukurumidza kwekristallisation uye kugadzira mune strand homogeneous, yakanaka-grained chimiro chinopa semi-yakapedza chigadzirwa yakanaka tekinoroji zvivakwa. Iyo tambo yakaomeswa inozotwasanudzwa uye ichichekwa kusvika pahurefu hwaidiwa neshears kana mwenje wekucheka.
Zvikamu zvinogona kushandirwazve mune zvinotevera-in-line rolling Operations kuti uwane mabara, tsvimbo, extrusion billets (blanks), slabs kana zvimwe zvigadzirwa zvakapedzwa muzvikamu zvakasiyana.
Nhoroondo yekuramba ichikanda
Kuedza kwekutanga kukanda simbi nenzira inopfuurira kwakaitwa pakati pezana ramakore rechi 19. Mugore ra1857, Sir Henry Bessemer (1813-1898) vakagashira patent yekukanda simbi pakati pemaroller maviri anotenderera ekugadzira simbi slabs. Asi panguva iyoyo nzira iyi yakaramba isina hanya. Kufambira mberi kwakasimba kwakaitwa kubva 1930 zvichienda mberi neiyo Junghans-Rossi tekinoroji yekuramba ichikanda mwenje uye simbi inorema. Nezvesimbi, iyo inoenderera mberi yekukanda maitiro akagadzirwa muna 1950, pamberi (uye zvakare mushure) iyo simbi yakadirwa muchimiro chakamira kuita 'ingots'.
Kuramba kuchikandwa kwetsvimbo isiri-ferrous yakagadzirwa neProperzi process, yakagadzirwa naIlario Properzi (1897-1976), muvambi wekambani yeContinuus-Properzi.
Zvakanakira kuramba uchikanda
Kuenderera mberi kukanda ndiyo nzira yakakwana yekugadzira zvigadzirwa zvehafu-yakapedzwa zvehukuru hurefu uye inogonesa kugadzirwa kweakawanda mukati menguva pfupi. Iyo microstructure yezvigadzirwa yakaenzana. Kuenzaniswa nekukanda muforoma, kuenderera mberi kukanda kune hupfumi maererano nekushandiswa kwesimba uye kunoderedza zvimedu zvishoma. Uyezve, zvinhu zvezvigadzirwa zvinogona kuchinjwa nyore nyore nekushandura mapeji ekukanda. Sezvo mabasa ese achigona kuve otomatiki uye achidzorwa, kuenderera mberi kukanda kunopa akawanda mikana yekuchinjika kugadzirwa uye nekukurumidza kuchinja musika zvinodiwa uye kuisanganisa nedigitization (Industrie 4.0) matekinoroji.
