Makina Opitilira Kuponya
Mfundo yogwira ntchito ya makina opopera osalekeza amtundu wamba amatengera malingaliro ofanana ndi makina athu oponyera vacuum. M'malo modzaza zinthu zamadzimadzi mu botolo mutha kupanga / kujambula pepala, waya, ndodo, kapena chubu pogwiritsa ntchito nkhungu ya graphite. Zonsezi zimachitika popanda thovu lililonse la mpweya kapena kuchepa kwa porosity. Makina oponyera vacuum ndi apamwamba opitilira muyeso amagwiritsidwa ntchito popanga mawaya apamwamba kwambiri monga mawaya omangira, semiconductor, gawo lazamlengalenga.
Kodi kuponyera mosalekeza ndi chiyani, ndi chiyani, ubwino wake ndi wotani?
Kuponyedwa kosalekeza ndi njira yabwino kwambiri yopangira zinthu zomwe zatha monga mipiringidzo, mbiri, slabs, mizere ndi machubu opangidwa kuchokera ku golide, siliva ndi zitsulo zopanda chitsulo monga mkuwa, aluminiyamu ndi alloys.
Ngakhale pali njira zosiyanasiyana zoponyera mosalekeza, palibe kusiyana kwakukulu pakuponya golidi, siliva, mkuwa kapena aloyi. Kusiyana kofunikira ndi kutentha kwa mpweya komwe kumayambira pafupifupi 1000 ° C ngati siliva kapena mkuwa mpaka 1100 ° C ngati golide kapena ma aloyi ena. Chitsulo chosungunuka chimaponyedwa mosalekeza mu chotengera chosungira chomwe chimatchedwa ladle ndipo chimayenda kuchokera pamenepo kupita ku nkhungu yoyima kapena yopingasa yokhala ndi mapeto otseguka. Pamene akuyenda mu nkhungu, amene utakhazikika ndi crystallizer, madzi misa amatenga mbiri nkhungu, amayamba kulimba pamwamba pake ndi kusiya nkhungu mu theka-olimba chingwe. Panthawi imodzimodziyo, kusungunula kwatsopano kumaperekedwa nthawi zonse ku nkhungu pa mlingo womwewo kuti ukhalebe ndi chingwe cholimba chosiya nkhungu. Chingwecho chimaziziritsidwanso ndi makina opopera madzi. Kupyolera mu ntchito kwambiri kuzirala n'zotheka kuonjezera liwiro la crystallization ndi kupanga mu chingwe ndi homogeneous, chabwino-grained kapangidwe kupereka theka-anamaliza mankhwala katundu wabwino umisiri. Kenako chingwe cholimbacho chimawongoleredwa ndikudulidwa mpaka kutalika kwake ndi kameta kapena tochi yodulira.
Magawowa atha kugwiritsidwanso ntchito pazotsatira zogubuduza pamzere kuti apeze mipiringidzo, ndodo, ma billets otulutsa (zopanda kanthu), ma slabs kapena zinthu zina zomalizidwa mosiyanasiyana.
Mbiri yakuponya mosalekeza
Kuyesera koyamba kuponya zitsulo mosalekeza kunachitika pakati pa zaka za m'ma 1800. M'chaka cha 1857, Sir Henry Bessemer (1813-1898) adalandira chilolezo choponya zitsulo pakati pa ma roller awiri ozungulira kuti apange zitsulo. Koma nthawi imeneyo njira imeneyi inalibe tcheru. Kupita patsogolo kotsimikizika kudapangidwa kuyambira 1930 kupita mtsogolo ndi njira ya Junghans-Rossi yopitilira kutulutsa kwazitsulo zopepuka komanso zolemera. Pankhani ya chitsulo, njira yopitilira yoponyera idapangidwa mu 1950, (komanso pambuyo pake) chitsulocho chidatsanulidwa mu nkhungu yokhazikika kuti ipange 'ingots'.
Kuponyedwa kosalekeza kwa ndodo yopanda chitsulo kunapangidwa ndi ndondomeko ya Properzi, yopangidwa ndi Ilario Properzi (1897-1976), yemwe anayambitsa kampani ya Continuus-Properzi.
Ubwino wa kuponyera mosalekeza
Kuponyera mosalekeza ndi njira yabwino kwambiri yopangira zinthu zomwe zamalizidwa pang'ono zazitali zazitali ndipo zimapangitsa kuti pakhale zochulukirapo pakanthawi kochepa. Ma microstructure azinthu ndi ofanana. Poyerekeza ndi kuponyera mu nkhungu, kuponyera mosalekeza kumakhala kopanda chuma pakugwiritsa ntchito mphamvu komanso kumachepetsa zinyalala zochepa. Komanso, katundu wa mankhwala akhoza kusinthidwa mosavuta ndi kusintha magawo akuponya. Popeza ntchito zonse zitha kupangidwa zokha ndikuwongoleredwa, kutulutsa kosalekeza kumapereka mwayi wambiri wosinthira kupanga mosavuta komanso mwachangu kuti zisinthe zomwe msika ukufunikira ndikuphatikiza ndi ukadaulo wa digito (Industrie 4.0).
