Vacuum unyango ubushushuyinkqubo ephambili yokuphucula iimpawu zomzimba kunye noomatshini kwiindawo zetsimbi.Kubandakanya ukufudumeza isinyithi kwigumbi elivaliweyo kwiqondo lokushisa eliphezulu ngelixa ligcina uxinzelelo oluphantsi, olubangela ukuba iamolekyu zegesi zikhuphe kwaye zivumela inkqubo yokufudumala efanayo.Esinye sezixhobo eziphambili ezisetyenziselwa unyango lwe-vacuum yokushisa i-vacuum yokushisa ukushisa, enokulawula ngokuchanekileyo ubushushu, umoya kunye noxinzelelo kwinkqubo.
Ukuqina kwevacuum yindlela eqhelekileyo esetyenziswa ngabavelisi ukunyusa amandla kunye nokuqina kwamalungu esinyithi.Ngokufudumeza isinyithi kwiqondo lokushisa eliphezulu kwisithando somlilo, ufumana utshintsho olubizwa ngokuba yi-austenitization, eyenza i-microstructure efanayo kunye nokuphucula iimpawu zomatshini.Le nkqubo isetyenziswa ngokuqhelekileyo ukwenza izinto ezilukhuni ezifana nentsimbi, i-titanium kunye ne-superalloys ezisetyenziswa ngokubanzi kwizicelo zoxinzelelo oluphezulu.
Unyango lobushushu be-vacuum alubalulekanga kuphela ekwenzeni lukhuni, kodwa nakwezinye iinkqubo ezininzi ezifana nokubrawuza, ukutshisa kunye nokufaka i-annealing.Inika iingenelo ezininzi kwiindlela zokunyanga ubushushu besintu, kubandakanya umgangatho ophezulu kunye nokuphinda-phinda, ukugqwetheka okuncitshisiweyo, kunye nokukwazi ukusebenzisa i-alloys esebenza kakhulu efana nezo zifumaneka kwi-aerospace kunye namashishini ezonyango.Ngaloo nto engqondweni, kuyacaca ukuba unyango lobushushu be-vacuum yinkqubo ebalulekileyo kumashishini amaninzi, ukuhambisa ukuphuculwa komsebenzi wecandelo kunye nokusebenza okukhulu kunye nokuthembeka.
Xa ukhetha ii-vacuum yonyango lokushisa eziko, izinto ezininzi kufuneka ziqwalaselwe, ezifana nohlobo lwesithando somlilo (i-batch okanye eqhubekayo), ukushisa okuphezulu kunye nobukhulu begumbi lesithando somlilo.Ukukhetha isithando somlilo esifanelekileyo kuya kuxhomekeka kwisicelo esithile kunye nohlobo lwezinto ezicutshungulwayo.Isithando somlilo esifanelekileyo sinokugcina amandla, siphucule umgangatho wemveliso kunye nokunciphisa iindleko zokucubungula, ngelixa isithando somlilo esingalunganga sinokuchaphazela kakhulu umgangatho wemveliso yokugqibela.
Ngamafutshane, unyango lobushushu be-vacuum yinkqubo ebalulekileyo yokuphucula ukusebenza kweengxenye zetsimbi.Ukukhetha isithando somlilo esifanelekileyo kubalulekile kwimpumelelo yenkqubo yakho, ukwandisa unyango lobushushu kunye nokuqinisekisa umgangatho wemveliso.I-aerospace, i-automotive, i-medical, kunye namanye amashishini amaninzi axhomekeke kunyango lwe-vacuum yokushisa, ngoko ukufumana umthengisi othembekileyo wenkqubo kubalulekile.
