i-silicon esheshayo

I-silicon esheshayo ye-Metal silicon, eyaziwa nangokuthi i-silicon yezimboni, iyisengezo esisetshenziswa kakhulu ekuncibilikiseni insimbi futhi isetshenziswa njenge-ejenti yokunciphisa inqubo yokuncibilikisa.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 sokuncibilikiswa kwensimbi, ukuze i-silicon yensimbi incibilike ngokushesha, futhi izinga lokushisa lokuphendula le-flux ngokuvamile aliphakeme, cishe ama-740 degrees Celsius, ngakho lolu hlobo lwe-silicon yensimbi. nge-flux eyengeziwe ibizwa nangokuthi i-silicon esheshayo.Isetshenziselwa ukulungisa okuqukethwe kwe-silicon kuma-alloys e-aluminium.

Omaka bomkhiqizo

Izinzuzo zokusebenzisa i-silicon esheshayo

1. Ijubane lokuqedwa liyashesha kakhulu, ukusabela kuyashesha, futhi isikhathi sigcinwa.

2. Okuqukethwe kuphezulu njengo-95%, okungalawula ngokunembile inani le-silicon engeziwe, futhi ilungise ngokushesha noma iyiphi ingxenye ye-aluminium-silicon alloy.

3. Kulula kakhulu ukuyisebenzisa, vele uyibeke phezu koketshezi lwe-aluminium, uyicindezele bese uyixuba.Izinga lokuthola kabusha 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 ngokuphawulekayo izinga lokushisa elincibilikayo, unciphise kakhulu isikhathi sokuncibilika, futhi unciphise 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 encibilikisiwe ifinyelela ku-740-770 ° C (inqubo yokwengeza i-silicon iwumphumela we-endothermic, izinga lokushisa lensimbi encibilikisiwe kufanele lishiswe ukuze izinga lokushisa lingabi ngaphansi kuka-740 ° C), phonsa i-silicon ejenti esheshayo encibilikisiwe. i-aluminium surface ukuze isetshenziswe, bese ucindezela insimbi ku-aluminium encibilikisiwe.Hlanganisa imizuzu engu-2-5.Incazelo yomkhiqizo: Okuqukethwe kwe-silicon kungu-95%, futhi kungancibilika ngokushesha ekushiseni okuphansi, okunciphisa kakhulu izindleko zezithako ze-alloy, futhi kungalungisa ngokushesha noma iyiphi i-silicon-aluminium alloy enokuqukethwe kwe-silicon;ukulawulwa kokwakheka kunembile kakhulu, futhi inani elikhulu lezinto ezifakiwe nezinto eziyingozi ezilethwa kalula ku-master alloy ziyaqedwa.Ukungcola, ukugwema ukusetshenziswa kwe-aluminiyamu exubile ukuze kulungiswe ama-alloys amakhulu e-aluminium-silicon kanye nomthelela wekhwalithi ye-alloy yokugcina ye-aluminium okunzima ukuyilawula.
