Unyango lobushushu be-vacuumyinkqubo ephambili yokuphucula iimpawu zomzimba neze-mechanical zeendawo zesinyithi. Ibandakanya ukufudumeza isinyithi kwigumbi elivaliweyo ukuya kubushushu obuphezulu ngelixa kugcinwa uxinzelelo oluphantsi, okubangela ukuba iimolekyuli zegesi ziphume kwaye kuvumela inkqubo yokufudumeza efanayo. Esinye sezixhobo eziphambili ezisetyenziswa kunyango lobushushu be-vacuum sisithando sonyango lobushushu be-vacuum, esinokulawula ngokuchanekileyo ubushushu, umoya kunye noxinzelelo kwinkqubo.
Ukuqinisa i-vacuum yindlela eqhelekileyo esetyenziswa ngabavelisi ukwandisa amandla kunye nokuqina kweendawo zesinyithi. Ngokufudumeza isinyithi kumaqondo obushushu aphezulu kwisithando somoya, itshintsha indlela ebizwa ngokuba yi-austenitization, edala isakhiwo esifanayo kwaye iphucule iimpawu zoomatshini. Le nkqubo isetyenziswa rhoqo ukuqinisa izinto ezifana nentsimbi, i-titanium kunye nee-superalloys ezisetyenziswa kakhulu kwizicelo zoxinzelelo oluphezulu.
Unyango lobushushu be-vacuum alubalulekanga nje kuphela ekuqiniseni, kodwa nakwiinkqubo ezininzi ezifana nokuqhotsa, ukuthulula kunye nokuqhotsa. Lubonelela ngeenzuzo ezininzi kuneendlela zonyango lobushushu zemveli, kubandakanya umgangatho ophezulu kunye nokuphindaphinda, ukunciphisa ukugqwetheka, kunye nokukwazi ukusebenzisa ii-alloys ezisebenzayo eziphezulu ezifana nezo zifumaneka kwimizi-mveliso yeenqwelo-moya kunye neyezonyango. Ngokucinga oku, kuyacaca ukuba unyango lobushushu be-vacuum yinkqubo ebalulekileyo kumashishini amaninzi, enikezela ukusebenza okuphuculweyo kwecandelo ngokusebenza kakuhle nangokuthembekileyo okukhulu.
Xa ukhethaisithando sonyango lobushushu be-vacuum, kufuneka kuqwalaselwe izinto ezininzi, ezinje ngohlobo lwe-furnace (ibhetshi okanye eqhubekayo), ubushushu obuphezulu kunye nobukhulu begumbi le-furnace. Ukukhetha i-furnace efanelekileyo kuya kuxhomekeka kwisicelo esithile kunye nohlobo lwezinto ezicutshungulwayo. I-furnace efanelekileyo inokonga amandla, iphucule umgangatho wemveliso kwaye inciphise iindleko zokucubungula, ngelixa i-furnace engalunganga inokuchaphazela kakhulu umgangatho wemveliso yokugqibela.
Ngamafutshane, unyango lobushushu be-vacuum yinkqubo ebalulekileyo yokuphucula ukusebenza kweendawo zesinyithi. Ukukhetha i-furnace efanelekileyo kubalulekile kwimpumelelo yenkqubo yakho, ukuphucula unyango lobushushu kunye nokuqinisekisa umgangatho wemveliso. I-aerospace, iimoto, ezonyango, kunye nezinye iinkampani ezininzi zixhomekeke kunyango lobushushu be-vacuum, ngoko ke ukufumana umthengisi othembekileyo wale nkqubo kubalulekile.
