Inkqubo yokuphosa yeubhedu lwe-silicon: ukunyibilika nokugalela.Ubhedu lwesilicon lunyibilikiswa kwiziko lokungenisa iasidi.Intlawulo kufuneka ifudunyezwe kwi-150 ~ 200 ℃ ngaphambi kokuba ifakwe kwisithando somlilo, kwaye ubhedu lwe-electrolytic kufuneka lucocwe, lutshiswe kwiqondo lokushisa eliphezulu kwaye luhlanjululwe kakuhle ngaphambi kokusetyenziswa.Ukubunjwa kweSi yi-3.1%, uMn yi-1.2%, kwaye enye i-Cu, kunye ne-Fe yi-0.25% kunye ne-Zn yi-0.3%.Umyalelo wokutya: okokuqala ukongeza i-0.5% ye-flux (i-boric acid + iglasi) yexabiso lentlawulo, yongeza i-silicon ye-crystalline, isinyithi se-manganese kunye nobhedu lwe-electrolytic, ukwandisa ubushushu ukuya kwi-1250 ℃, yongeza isinyithi kunye ne-zinc, de iqondo lokushisa liphakame ukuya kwi-1300 ℃, ubambe i-10 min, emva koko isampuli kwaye ugalele kwibhloko yovavanyo lwesanti.Ukuba ibhloko yovavanyo icinezelekile phakathi emva kokupholisa, kuthetha ukuba i-alloy iyinto eqhelekileyo, i-slag ikhupha kwi-oven kwaye ihlanganiswe ne-perlite ukukhusela i-oxidation kunye nokuphefumlelwa.
Iqondo lobushushu lokugalela laliyi-1090 ~ 1120 ℃.Kwiindawo ezinkulu ezinodonga olucekeceke, kuyacetyiswa ukuba usebenzise inaliti ephezulu okanye inyathelo lenyathelo lokungena.Xa iqondo lobushushu lokugalela lidlula i-1150 ℃, ukuqhekeka okushushu kulula ukwenzeka, ngelixa ubushushu bokugalela bungaphantsi kwe-1090 ℃, iziphene ze-undercasting ziyenzeka.
Xa kuthelekiswa ne-tin bronze (Sn 9%, Zn 4%, Cu), uluhlu lokuqiniswa kwe-silicon yobhedu yi-55℃, ngelixa i-tin bronze yi-146℃, ngoko ke ukumanzi kwayo kuphezulu kunobhedu lwe-tin.Kuyabonakala ukuba ubhedu lwesilicon luphezulu kakhulu kunobhedu lwetin kwiqondo lobushushu elifanayo lokugalelwa.
Ukusebenza kwe-welding ye-silicon bronze, ukusebenza kwe-welding ye-alloys ezahlukeneyo zobhedu kwahlulwe ngokwamanqanaba ama-4 ngokwezinto ezintle kunye nezibi, iBanga loku-1 ligqwesile, iBanga lesi-2 liyanelisa, ibakala lesi-3 liyakwazi ukuwelda ngenkqubo ekhethekileyo, ibakala lesi-4 alinelisi, i-Tin bronze libakala lesi-3, ngelixa i-silicon ye-silicon ye-bronze yebakala 1 iyi-2.
Xa kuthelekiswa nezinye iialloyi zobhedu, i-silicon bronze ine-conductivity ephantsi ye-thermal kwaye ayifuni ukufudumeza kwangaphambili ngaphambi kwe-welding, kodwa ine-brittleness ye-thermal kuluhlu lwe-815 ~ 955 ℃.Nangona kunjalo, ukuba ipleyiti ephosiweyo isemgangathweni olungileyo, oko kukuthi, ipleyiti ephosiweyo emva kokuthatha amanyathelo okuphucula ubugcisa, uqheliselo lubonakalise ukuba ukuqhekeka okutshisayo akuyi kwenzeka kule ndawo yokushisa.
Ubhedu lweSilicon lunokuba yi-gas welding, i-arc welding, i-TIG ye-manual kunye ne-MIG welding.
