i-silicon esheshayo

Ukusebenza:

1. Iqukethe95% i-silicon, futhi ibhalansi iyaguquguquka.

2. Ukuncibilika okusheshayo (imvamisangaphansi kwemizuzu emi-5); 90% isivuno.

3.Ifanele ukungezwa noma ukulungiswa kwei-silicon (Si) elementnge-aluminium alloy.

I-silicon esheshayo ye-Metal silicon, eyaziwa nangokuthii-silicon yezimboni, iyisengezo esisetshenziswa kakhulu ekuncibilikiseni insimbi futhi sisetshenziswa njengei-ejenti yokunciphisaenqubweni yokuncibilika.I-silicon iphinde ibe yingxenye enhle kuma-alloys e-aluminium, futhi ama-alloys amaningi e-aluminium cast aqukethe i-silicon.I-silicon esheshayo ingaphandle lensimbi ye-silicon kanye ne-flux.Umsebenzi we-flux ukukhiqiza ukushisa okuningi ngesikhathi sokuncibilika kwensimbi, ukuze insimbii-silicon iyancibilika ngokushesha, futhi izinga lokushisa lokusabela lokugeleza ngokuvamile aliphezulu, cishe740 degreesI-Celsius, ngakho lolu hlobo lwe-Metal silicon ene-flux eyengeziwe lubizwa nangokuthi i-silicon esheshayo.Isetshenziselwa ukulungisa okuqukethwe kwe-silicon kuma-alloys e-aluminium.

Omaka bomkhiqizo

Izinzuzo zokusebenzisa i-silicon esheshayo

1. Iisivinini sokuhlakazeka sishesha kakhulu, ukusabela kuyashesha, futhiisikhathi sigcinwa.

2. Iokuqukethwe kuphezulu njengokungu-95%, engalawula ngokunembile inani le-silicon engeziwe, futhi ilungise ngokushesha noma iyiphi ingxenye ye-aluminium-silicon alloy.

3. Kunzima kakhuluelula ukuyisebenzisa, vele uyibeke phezu koketshezi lwe-aluminium, uyicindezele bese uyinyakazisa.Iizinga lokutakula likhulu kuno-90%.

4. Umkhiqizo ofanele oshintshwayo wama-alloys aphakathi kwe-aluminium-silicon.Iqeda inqwaba yezinto ezifakiwe nezinto eziyingozi ezilethwa kalula ku-aluminium-silicon alloys, futhi igwema ukusetshenziswa kwemfucuza kanye ne-aluminium exubile ukulungisa ama-alloys e-aluminium-silicon, okunzima ukulawula ikhwalithi yokugcina i-aluminium alloy.

5. Yehlisa kakhulu izinga lokushisa lokuncibilika, kakhulu ukunciphisa isikhathi sokuncibilika, futhiukunciphisa kakhulu izindleko zezithako ze-alloy.

Isicelo

Noma yimuphi ukhonkolo oqukethe i-silicon noma i-aluminium ekhandiwe equkethe igolide.Izinga lokushisa elisetshenziswayo: 740-770℃ (uma izinga lokushisa liphezulu, umphumela uba ngcono)

Isetshenziswa kanjani

Ngemuva kokuthi konke ukushaja kuncibilikile, gubungula kahle futhi uthathe amasampula ukuze ahlaziywe.Bala inani elingeziwe le-silicon encibilika ngokushesha ngokuya ngemiphumela yokuhlaziya.Lapho i-aluminium encibilikisiweifinyelela ku-740-770 °C(inqubo yokwengeza i-silicon iwukusabela kwe-endothermic, izinga lokushisa lensimbi encibilikisiwe kufanele lishiswe ukuze kugcinwe izinga lokushisa.hhayi ngaphansi kuka-740 °C), phonsa i-silicon esheshayo endaweni encibilikisiwe ye-aluminium ukuze isetshenziswe, bese ucindezela insimbi ku-aluminium encibilikisiwe.Hlanganisa imizuzu engu-2-5.Incazelo yomkhiqizo: Theokuqukethwe kwe-silicon kungu-95%, futhi kungabaancibilike ngokushesha ekushiseni okuphansi, okuthikunciphisa kakhulu izindleko zezithako ze-alloy, futhi ingalungisa ngokushesha noma iyiphi ingxubevange ye-silicon-aluminium enokuqukethwe kwe-silicon;ukulawula ukwakheka kunembe ngokwedlulele, kanye nenani elikhulu leokufakiwenokulimazayoizintoezilethwa kalula ku-liminmaster alloy ziyadliwa.Ukungcola, ukugwema ukusetshenziswa kwe-aluminiyamu exubile ukuze kulungiswe ama-alloys amakhulu e-aluminium-silicon kanye nomthelela wekhwalithi ye-alloy yokugcina ye-aluminium okunzima ukuyilawula.
