isilicon ekhawulezayo Umfanekiso obonakalayo

i-silicon yangoko

I-silicon ye-Metal ye-Instant, ekwabizwa ngokuba yi-silicon yezoshishino, sisongezo esisetyenziswa kakhulu ekunyibilikiseni isinyithi kwaye sisetyenziswa njenge-arhente yokunciphisa kwinkqubo yokunyibilikisa.I-Silicon iphinde ibe yinto efanelekileyo kwi-alloys ye-aluminium, kwaye ininzi ye-aluminium alloys ephosiweyo iqulethe i-silicon.Isilicon ekhawulezileyo ngumphezulu ongaphandle wentsimbi yesilicon kunye ne-flux.Umsebenzi we-flux kukuvelisa ubushushu obuninzi kwinkqubo yokunyibilikiswa kwesinyithi, ukwenzela ukuba i-silicon yesinyithi inyibilika ngokukhawuleza, kwaye iqondo lokushisa lokuphendula le-flux alikho phezulu, malunga ne-740 degrees Celsius, ngoko olu hlobo lwe-silicon yesinyithi. nge-flux eyongeziweyo ikwabizwa ngokuba yisilicon ekhawulezileyo.Isetyenziselwa ukulungelelanisa umxholo we-silicon kwii-alloys ze-aluminium.

Izinto eziluncedo zokusebenzisa isilicon ekhawulezileyo

1. Isantya sokunyibilika sikhawuleza kakhulu, ukusabela ngokukhawuleza, kwaye ixesha ligcinwa.

2. Umxholo uphezulu njenge-95%, enokulawula ngokuchanekileyo inani le-silicon eyongeziweyo, kwaye ulungise ngokukhawuleza nayiphi na inxalenye ye-aluminium-silicon alloy.

3. Kukulungele kakhulu ukuyisebenzisa, yibeke nje phezu kolwelo lwe-aluminium, yicinezele kwaye uyishukumise.Izinga lokubuyisela likhulu kune-90%.

4. Imveliso efanelekileyo yokutshintshwa kwe-aluminium-silicon intermediate alloys.Iphelisa inani elikhulu lokufakwa kunye nezinto ezinobungozi ezingeniswa ngokulula kwi-aluminium-silicon alloys, kwaye igweme ukusetyenziswa kwenkunkuma kunye ne-aluminium exutywe ne-aluminium edibeneyo ukulungiselela i-aluminium-silicon alloys, enzima ukulawula umgangatho we-alloy aluminium yokugqibela.

5. Ukunciphisa kakhulu ukushisa okunyibilikayo, ukunciphisa kakhulu ixesha lokunyibilika, kunye nokunciphisa kakhulu iindleko zezithako ze-alloy.

Isicelo

Nayiphi na i-silicon equlathe isamente okanye ialuminiyam ekhandiweyo enegolide.Sebenzisa ubushushu: 740-770℃ (okukhona ubushushu obuphezulu, kokukhona umphumo ungcono)

Kusetyenziswa kwanjani

Emva kokuba yonke intlawulo iyancibilika, gxuma kakuhle kwaye uthathe iisampuli zohlalutyo.Bala inani elongezelelweyo le-silicon enyibilikayo ngokukhawuleza ngokweziphumo zohlalutyo.Xa i-aluminiyam etyhidiweyo ifikelela kwi-740-770 °C (inkqubo yokongeza i-silicon yi-endothermic reaction, ubushushu bentsimbi etyhidiweyo kufuneka bufudunyezwe ukugcina ubushushu bungekho ngaphantsi kwe-740 °C), phosa i-agent ye-silicon esheshayo umphezulu we-aluminiyam ukuze usetyenziswe, kwaye ucinezele intsimbi kwi-aluminiyam etyhidiweyo.Gcoba kwi-2-5 imizuzu.Inkcazo yeMveliso: Umxholo we-silicon ngu-95%, kwaye unokuncibilika ngokukhawuleza kwiqondo lokushisa eliphantsi, elinciphisa kakhulu iindleko zezithako ze-alloy, kwaye unokulungisa ngokukhawuleza nayiphi na i-silicon-aluminium alloy kunye nomxholo we-silicon;ulawulo lokubunjwa luchaneke ngokugqithiseleyo, kwaye inani elikhulu lokubandakanywa kunye nezinto ezinobungozi eziziswa ngokulula kwi-master alloy ziyacinywa.Ukungcola, ukuphepha ukusetyenziswa kwenkunkuma exubileyo ye-aluminium ukulungiselela i-aluminium-silicon master alloys kunye nefuthe kumgangatho we-alloy ye-aluminium yokugqibela ekunzima ukuyilawula.
