Inqubo yokulingisa yeithusi le-silicon: ukuncibilika nokuthela.Ithusi le-silicon lincibilikiswa esithandweni sokungenisa i-asidi.Inkokhiso kufanele ishiswe ngaphambili ibe ngu-150 ~ 200℃ ngaphambi kokufakwa esithandweni, futhi ithusi le-electrolytic kufanele lihlanzwe, losiwe ekushiseni okuphezulu futhi licoliswe ngokuphelele ngaphambi kokusetshenziswa.Ukwakhiwa kwe-Si ngu-3.1%, uMn ngu-1.2%, kanti enye ithi Cu, kanye ne-Fe ingu-0.25% bese i-Zn ingu-0.3%.I-oda lokudla: qala ungeze u-0.5% we-flux (i-boric acid + ingilazi) yenani lokushaja, engeza i-crystalline silicon, insimbi ye-manganese ne-electrolytic yethusi, ukhuphule izinga lokushisa libe ngu-1250 ℃, engeza insimbi ne-zinc, kuze kufike izinga lokushisa libe ngu-1300 ℃, ubambe. imizuzu eyi-10, bese wenza isampula bese uthela ebhulokhini yokuhlola isikhunta sesihlabathi.Uma i-block test icindezelekile phakathi ngemva kokupholisa, kusho ukuthi i-alloy ijwayelekile, i-slag ikhishwa kuhhavini futhi ihlanganiswe ne-perlite ukuvimbela i-oxidation nokuphefumulelwa.
Izinga lokushisa lokuthulula lalingu-1090 ~ 1120 ℃.Ezingxenyeni ezinkulu ezinodonga oluncane oluncane, kuyancomeka ukuthi usebenzise umjovo ophezulu noma isistimu yokufaka umjovo oseceleni.Lapho izinga lokushisa elithela lidlula i-1150 ℃, ukuqhekeka okushisayo kulula ukwenzeka, kuyilapho izinga lokushisa elithela lingaphansi kuka-1090 ℃, ukukhubazeka okungaphansi kulula ukwenzeka.
Uma kuqhathaniswa ne-tin bronze (Sn 9%, Zn 4%, Cu), uhla lokuqiniswa kwe-silicon bronze luyi-55℃, kanti lolu lwe-tin bronze luyi-146℃, ngakho uketshezi lwalo lungaphezu kolwethusi.Kuyabonakala ukuthi ithusi le-silicon liphakeme kakhulu kunethusi le-tin ngezinga lokushisa elifanayo lokuthulula.
Ukusebenza kokushisela kwe-silicon yethusi, ukusebenza kokushisela kwama-alloys ethusi ahlukahlukene kuhlukaniswe ngamabanga ama-4 ngokuya ngobuhle nobubi bawo, ibanga loku-1 lihle kakhulu, ibanga lesi-2 liyanelisa, ibanga lesi-3 liyashiseka ngenqubo ekhethekile, ibanga lesi-4 aligculisi, iTin I-bronze iyibanga lesi-3, kanti i-silicon bronze iyibanga loku-1.
Uma kuqhathaniswa namanye ama-alloys ethusi, ithusi le-silicon linomoya oshisayo ophansi futhi alidingi ukushisa ngaphambi kokushisela, kodwa linokushisa okushisayo ebangeni elingu-815 ~ 955℃.Kodwa-ke, uma ipuleti elikhonjiwe lisezingeni elihle, okungukuthi, ipuleti elikhonjiwe ngemuva kokuthatha izinyathelo zokuthuthukisa ezobuchwepheshe, umkhuba ufakazele ukuthi ukuqhekeka okushisayo ngeke kwenzeke kule ndawo yokushisa.
I-silicon yethusi ingaba igesi yokushisela, i-arc welding, i-TIG ye-manual kanye ne-MIG.
