I-Silicon yeNsimbi yokuCasa

Ukuphoswa kwesinyithi bubuchule bakudala obubalulekile kwimpucuko yabantu kangangeenkulungwane. Ukusuka ekudalweni kwemifanekiso eqingqiweyo entsonkothileyo ukuya kwimizi-mveliso entsonkothileyo, ukutyhilwa kwesinyithi kudlala indima ebalulekileyo kumashishini ahlukeneyo.Isilicon, into edla ngokunxulunyaniswa nobuchwepheshe obuphambili, yenye yezona zinto ziluncedo eluntwini. Isetyenziswa kakhulu ukwenza i-aluminiyam-iingxube ze-siliconkwayei-ferrosilicon(i-iron-silicon) i-alloys, nayo inempembelelo ebalulekileyo kwinkqubo yokuphosa isinyithi. I-China, iRashiya, iNorway, kunye neBrazil zezona zivelisa iiminerali ze-silicon. Kweli nqaku, siza kuntywila nzulu ekusebenziseni i-silicon ekugaleleni isinyithi, siphonononga iipropati zayo, usetyenziso, kunye neendlela eziphucula ngayo inkqubo yokuphosa.

Ukuqonda iSilicon kwiMetal Casting

I-silicon yinto eguquguqukayo esetyenziswa ngokubanzi kwintsimbi yokuphosa ngenxa yeempawu zayo ezizodwa. Xa idityaniswe ngeentsimbi ezifana ne-aluminiyam, ubhedu, kunye nentsimbi, i-silicon yongeza ukomelela, ukuqina, kunye nokumelana nomhlwa kwe-alloy ephumayo. Ezi zakhiwo ziphuculweyo zoomatshini zenza i-silicon alloys ixabiseke ngakumbi kumashishini apho ukuqina kunye nokusebenza kubaluleke kakhulu.

Kutheni le nto iSilicon ifanelekile kwiMetal Casting

Indawo yokuNyibilika ePhakamileyo: I-silicon inendawo ephezulu yokunyibilika, eyenza ukuba ifaneleke kwizicelo eziphezulu zokushisa ezifana nokuphosa isinyithi.
Ukwandiswa kweThermal ephantsi: I-Silicon inepropati ephantsi yokwandisa i-thermal, enceda ukunciphisa umngcipheko woxinzelelo lwe-thermal ngexesha lokuphosa.
Ubumanzi obuhle: I-Silicon iphucula ubumanzi besinyithi esinyibilikisiweyo, ivumela ukuba ihambe ngokulula kwiimbumba eziyinkimbinkimbi kunye nemigodi.
Amandla aphuculweyo: I-Silicon yonyusa amandla kunye nobulukhuni be-alloys zetsimbi, izenza zilungele izicelo ezifuna iimpawu eziphezulu zoomatshini.

Ukusetyenziswa kweSilicon kwiMetal Casting

1. Ukuphoswa kweAluminiyam: I-silicon isetyenziswa ngokuqhelekileyo kwi-aluminium casting ukuphucula iimpawu zemishini ye-alloy. Iialloyi ze-aluminiyam-silicon zikhaphukhaphu kwaye zinokumelana nokugqwesa okugqwesileyo, zizenza zilungele i-aerospace kunye nokusetyenziswa kweemoto.

2. Jula i-ayini: Kwintsimbi etyhidiweyo, i-silicon yongezwa kwintsimbi engwevu ukukhuthaza ukubunjwa kwe-graphite flakes, ephucula ukucwangciswa kwezinto kunye neempawu zokudambisa. I-silicon iphinda iphucule ukuxhathisa ukunxiba kwe-ferroalloys.

3. Intsimbi yentsimbi: I-Silicon isetyenziselwa isinyithi esityhidiweyo ukuze i-deoxidize isinyithi esityhidiweyo kunye nokuphucula umbane wayo. I-Silicon ikwanceda ukulawula ubungakanani beenkozo zentsimbi, okukhokelela ekomeleleni, ukuphosa okubhetyebhetye ngakumbi.

Indima yeSilicon ekuphuculeni iNkqubo yokuCasa

Ukuphucuka kwamanzi: I-silicon iphucula ubumanzi besinyithi esinyibilikisiweyo, ivumela ukuba izalise ngokulula imingxuma yokungunda entsonkothileyo. Le propathi ibalulekile ekufezekiseni ukuphoswa okuntsokothileyo kunye neenkcukacha.

Ukunciphisa Ukuncipha: Ukongeza i-silicon kwii-alloys zetsimbi kunceda ukunciphisa iziphene ze-shrinkage kwi-castings, ukuqinisekisa ukuchaneka kwe-dimensional kunye nokunciphisa imfuno yomatshini owongezelelweyo.

Ukuphucula ukuSebenza: Ukucutshungulwa kulula ukusetyenzwa. Le propathi iluncedo ngakumbi kwizicelo ezifuna umatshini wokwenziwa ngasemva.

Imingeni kunye neNgqwalasela

Ngelixa i-silicon ibonelela ngeengenelo ezininzi zokuphosa isinyithi, kukwakho imingeni ekufuneka iqwalaselwe:

1. Ubuqhophololo: Ukuphakama kakhulu umxholo we-silicon kunokubangela i-alloy brittleness, enokuthi iphazamise iimpawu zayo zomatshini. Uyilo olufanelekileyo lwe-alloy kunye nolawulo lomxholo we-silicon lubalulekile ekuthinteleni le ngxaki.

2. I-Porosity: Ukuba ayilawulwa kakuhle, i-silicon inokunyusa umngcipheko we-porosity kwi-castings. Kufuneka kuthathwe amanyathelo angqongqo okusebenza ngoomatshini kunye namanyathelo okulawula umgangatho ukuze kuncitshiswe iporosity.

3. Iindleko: I-silicon yinto ebiza kakhulu echaphazela ixabiso elipheleleyo lokuvelisa i-silicone-containing alloys. Uhlalutyo lweendleko-inzuzo luyimfuneko ukumisela ukuba kunokwenzeka ukusebenzisa i-silicon kwisicelo esithile sokuphosa.
