Iimveliso ze-aluminium alloy zisetyenziswa ngokubanzi kwiinkalo ezininzi ngenxa yokusebenza kwazo okugqwesileyo.Nangona kunjalo, ukusebenza kwabo okugqwesileyo akunakuhlukaniswa kwiindidi zezongezo ze-aluminium alloy.Kwiminyaka yakutshanje, izongezo ze-aluminium alloy ziye zaba yinxalenye ebalulekileyo yokuphucula ukusebenza kwee-alloys ze-aluminium kunye nokucocwa kwesakhiwo sengqolowa.
Aluminiyam ingxubevange izongezoziikhemikhali ezongezwa kwintsimbi etyhidiweyo ngexesha lokwenziwa kwemveliso.Ezi zongezo zisebenza imisebenzi eyahlukeneyo kwaye zinempembelelo enkulu kwimveliso yokugqibela.Indima yezongezo ezahlukeneyo iyahluka, umzekelo,izongezo zechromium, edlala indima ebalulekileyo ekongezwa kwechromium kwi-alloys ye-aluminium kunye nokucocwa kwesakhiwo sengqolowa, kunyeizongezo zemanganese, enokuchaphazela umxholo we-manganese kwiimveliso ze-aluminium alloy.
Kwi-zhelu, izongezo ze-aluminium alloy zikwabizwa ngokuba yi-75% yezongezo ze-aluminium alloy, oku kuthetha ukuba umxholo wezinto zekhemikhali eziza kongezwa kwi-additive yi-75% kwaye enye i-aluminium, edlala indima ebalulekileyo ekuphuculeni ukusebenza kunye nokunciphisa i-aluminiyam. umgangatho weemveliso ze-aluminium alloy.Ukongezelela, izongezo ze-aluminium alloy eziveliswa yi-zhelu zinemveliso engaphezu kwe-95%.Oku kwandisa ukusetyenziswa kwemathiriyeli ekrwada, kunciphisa inkunkuma kwaye kwandisa ukusebenza kakuhle.Oku akuncedi kuphela abavelisi ukunciphisa iindleko, kodwa kukhuthaza uphuhliso oluzinzileyo lweshishini lonke.
Ukukhuselwa kwendalo kunye nokungangcoliseki kube yinkxalabo enkulu eluntwini.Kukho ukuqonda okukhulayo ngokubaluleka kokukhusela okusingqongileyo kunye nemfuneko yemilinganiselo ehambelana nokusingqongileyo kuwo onke amashishini.Enye yeenzuzo eziphambili zokusebenzisa izongezo ze-aluminium alloy kukukhusela okusingqongileyo.Izinto ezinobungozi ziveliswa ngokungenakuthintelwa kwimveliso yeekhemikhali.izongezo zezhelu zijolise ekukhuselweni kwendalo kunye nemveliso engangcolisekiyo.Bathobela imigaqo engqongqo kunye nokunceda ukunciphisa ukukhutshwa kwezinto ezingcolileyo eziyingozi ngexesha lenkqubo yokuvelisa.
Ezinye izongezo ze-aluminium alloy nazo zinefuthe elibalulekileyo lokucoca kwi-alloy.Ngokuzisa izinto ezithile kwintsimbi etyhidiweyo, ezi zongezo zinceda ukuphelisa ukungcola, ukuphucula i-homogeneity ye-alloy kunye nokuphucula iimpawu zayo zomatshini.Umzekelo,intsimbi ye-magnesium, yongeza i-magnesium ingot eyona njongo kukuphucula i-aluminium alloy die casting performance indicators, ingakumbi ukuxhathisa ukubola.Ngokutsho kweengcali, i-aluminiyam kunye ne-magnesium alloy die casting ilula kwaye inzima, ukuxhathisa okulungileyo kokuhlwa, kulula ukuyidibanisa kunye nolunye unyango olungaphezulu, kukuveliswa kweenqwelo-moya, iirokethi, izikhephe ezikhawulezayo, izithuthi kunye nezinye izinto ezibalulekileyo.Ukongezelela, indima yezongezo ze-aluminium i-alloy additives ayikona nje ukuphucula iimpawu zoomatshini, ezi zongezo zikwaphucula i-machinability ye-alloy, okwenza kube lula ukucubungula nokuphatha.Banceda ukunciphisa iziphene ezenzeka ngexesha lokuphosa kunye nokubumba, ngaloo ndlela ukwandisa izivuno kunye nokunciphisa amazinga e-scrap.Ukuphuculwa kobuchule kwezi zongezo kunceda ukugcina iindleko kunye nokuqinisekisa ukuveliswa kwamacandelo aphezulu.
Nangona izongezo zidlala indima ebalulekileyo ekusebenzeni kweemveliso ze-aluminium alloy, abavelisi nabo kufuneka baphuhlise iinkqubo ezahlukeneyo ngokusekelwe kwiimpawu zezongezo ezahlukeneyo kunye nokushisa kwazo okusebenzayo.Ngokomzekelo, i-chromium, i-manganese kunyeubhedu kwialluminiyam izongezo kufuneka zongezwe kuphela xa amaqondo obushushu okusebenza engaphezulu kwama-730°C, kantiisiliconkwayeintsimbikufuneka isetyenziswe kwindawo ye-740 ° C kunye ne-750 ° C, ngokulandelelanayo.Ukongeza, kwidosi, i-zhelu ikhokelwa ngokubanzi yile seti yeefomyula:
usetyenziso oluchanekileyo lwezongezo luthatha isigqibo somgangatho wokugqibela weemveliso ze-aluminium alloy.
Ukuqukumbela, izongezo ze-aluminium alloy zidlala indima ebalulekileyo ekuveliseni i-alloys yokusebenza ephezulu ehambelana nokusingqongileyo.Ezi zongezo zinegalelo ekuzinzeni koshishino ngokugxininisa kwiinkqubo ezilungele ukusingqongileyo nezingangcolisi.Ukukwazi kwabo ukucokisa ukwakhiwa kweenkozo, ukunyusa umxholo wento kwi-alloy ye-aluminium kunye nokuphucula ukucwangciswa kwe-alloy kubenza babaluleke kakhulu kwiinkalo ezahlukeneyo.Njengoko imfuno yezinto ezihambelana nokusingqongileyo kunye nekhwalithi ephezulu iqhubeka ikhula, kuya kuba njalo ukubaluleka kwezongezo ze-aluminium alloy, ukuvula indlela yekusasa eliluhlaza, elisebenzayo.
