The casting process yesilicon bronze: kunyunguduka nekudira.Silicon bhuronzi inonyungudutswa muvira re acid induction.Mhangura inofanira kupiswa kusvika 150 ~ 200 ℃ isati yaiswa muchoto, uye mhangura ye electrolytic inofanira kucheneswa, yakagochwa pakupisa kwepamusoro uye yakanyatsosvibiswa isati yashandiswa.Kuumbwa kweSi 3.1%, Mn 1.2%, uye imwe yose ndeyeCu, pamwe neFe ndeye 0.25% uye Zn 0.3%.Kurongeka kwekudya: tanga wawedzera 0.5% flux (boric acid + girazi) yehuwandu hwekuchaja, wedzera crystalline silicon, manganese simbi uye electrolytic mhangura, wedzera tembiricha kusvika 1250 ℃, wedzera simbi uye zinc, kusvika tembiricha yakwira kusvika 1300 ℃, bata kwemaminetsi gumi, wobva waisa sampuli uye wodira mujecha mold test block.Kana test block yakaora mwoyo nepakati mushure mekutonhora, zvinoreva kuti alloy yakajairika, slag inotsvaira kubva muchoto uye yakavharwa ne perlite kudzivirira oxidation uye kufemerwa.
Tembiricha yekudurura yaive 1090 ~ 1120 ℃.Kune mahombe matete-madziro ane madziro, zvinokurudzirwa kutora epamusoro jekiseni kana padivi jekiseni nhanho gating system.Kana tembiricha yekudurura inopfuura 1150 ℃, kupisa kunopisa kuri nyore kuitika, nepo tembiricha yekudurura iri pazasi 1090 ℃, kuremara kwepasi kuri nyore kuitika.
Kuenzaniswa netin bhuronzi (Sn 9%, Zn 4%, Cu), iyo yekuomeswa kwesilicon bronze i55 ℃, nepo yerata yebhuronzi iri 146 ℃, saka fluidity yakakwira kupfuura iya yerata yebhuronzi.Zvinogona kuonekwa kuti silicon bhuronzi yakakwira zvakanyanya kupfuura tin bronze panguva imwechete yekudurura tembiricha.
Kuiswa kwemasimbi esilicon bronze, kukwenenzverwa kwemhando dzakasiyana dzemhangura dzemhangura dzakakamurwa kuita giredhi 4 maererano nezvayakanakira nezvayakaipira, giredhi 1 rakanaka kwazvo, giredhi 2 rinogutsa, giredhi rechitatu rinogoneka nemaitiro akakosha, giredhi 4 harigutse, Tin bronze igiredhi 3, nepo giredhi resilicon bhuronzi igiredhi.
Kana ichienzaniswa nemamwe maalloys emhangura, silicon bhuronzi ine yakadzika yekupisa conductivity uye haidi preheating isati yatungidzirwa, asi ine brittleness yekupisa mukati me815 ~ 955 ℃.Nekudaro, kana ndiro yakakandwa iri yemhando yakanaka, kureva kuti, ndiro yakakandwa mushure mekutora matanho ekuvandudza tekinoroji, tsika yakaratidza kuti kupisa kunopisa hakuzoitika munzvimbo ino yekushisa.
Silicon bronze inogona kuve gasi welding, arc welding, manual TIG welding uye MIG welding.
