Namuhla, ngizokuyisa e-Donghuan Malleable Iron Casting Co., Ltd. Ake sifunde ngenqubo yokuphonsa kwesihlabathi esimboziwe.
I.Ulwazi nokuqonda ngesihlabathi esimboziwe
1. Izici zesihlabathi esiboshwe
Inokusebenza okufanelekile kwamandla;i-fluidity enhle, isikhunta sesihlabathi esilungisiwe kanye nezinsimbi zesihlabathi zinezingqimba ezicacile nezakhiwo eziminyene, ezingakhiqiza ama-sand cores ayinkimbinkimbi;isikhunta sesihlabathi (ama-cores) anekhwalithi enhle yendawo, futhi ukugoqa kwendawo kungafinyelela ku-Ra = 6.3～12.5μm, Ukunemba kwe-dimensional kungafinyelela izinga le-CT7～CT9;ukugoqeka kuhle, futhi ukusakaza kulula ukuhlanza.
2. Ububanzi besicelo
Isihlabathi esimboziwe singasetshenziswa ukwenza isikhunta nama-sand cores.Isikhunta noma izintambo zesihlabathi esiboshwe zingasetshenziswa ngokuhambisana nomunye nomunye noma nezinye izibungu zesihlabathi (ama-cores);angeke isetshenziselwe ukuphonswa kwamandla adonsela phansi ensimbi kuphela noma ukukhishwa kwengcindezi ephansi, kodwa futhi Ingasetshenziselwa ukukhishwa kwensimbi eboshwe ngesihlabathi kanye nokusakazwa kwe-centrifugal okushisayo;ingasetshenziswa hhayi kuphela ukukhiqizwa kwe-cast iron kanye ne-non-ferrous alloy castings, kodwa futhi nokukhiqizwa kwensimbi yensimbi.
II.Ukulungiselela isihlabathi camera
1. Ukwakheka kwesihlabathi esiboshwe
Ngokuvamile yakhiwe ngezinto eziphikisayo, izibophezelo, ama-ejenti okwelapha, okothambisa kanye nezithasiselo ezikhethekile.
2. Inqubo yokukhiqiza yesihlabathi esiboshwe
Inqubo yokulungisa isihlabathi esimboziwe ngokuyinhloko ihlanganisa ukugqoka okubandayo, ukunamathela okufudumele, nokwemboza okushisayo.Njengamanje, cishe konke ukukhiqizwa kwesihlabathi esimboziwe kusebenzisa indlela yokushisa eshisayo.
3. Izinhlobo zomkhiqizo eziyinhloko zesihlabathi esiboshwe
(1) Isihlabathi esivalekile esivamile siyisihlabathi esimbozwe ngokwesiko
(2) Isihlabathi esinamanzi esinamandla aphezulu kanye ne-low-gassing
Izici: amandla aphezulu, ukunwetshwa okuphansi, igesi ephansi, igesi ehamba kancane, i-anti-oxidation
(3) Ukumelana nezinga lokushisa eliphezulu (uhlobo) lwesihlabathi esimboziwe (uhlobo lwe-ND)
Izici: ukumelana nokushisa okuphezulu, amandla aphezulu, ukwanda okuphansi, igesi ephansi, igesi ehamba kancane, ukuwa kalula, i-anti-oxidation
(4) Isihlabathi esinamekwe esigoqeka kalula
Inamandla amahle nokusebenza okuhle kakhulu kokuwa kwezinga lokushisa eliphansi, elifanele ukukhiqizwa kwezinsimbi ezingenayo insimbi.
(5) Ezinye izimfuneko ezikhethekile ezinamekwe ngesihlabathi.
III.Inqubo eyinhloko yokwenza umgogodla ngesihlabathi esiboshwe
Izinga lokushisa lokushisa liyi-200-300 ℃, isikhathi sokuphulukisa singama-30-150s, futhi ukucindezela kwesihlabathi sokudubula ngu-0.15-0.60MPa.Ukuze uthole ama-sand cores anezimo ezilula nesihlabathi esimbozwe nge-fluidity enhle, ukucindezela okuphansi kokudubula kungakhethwa.Ukuze uthole ama-sand cores amancane, izinga lokushisa eliphansi lokushisa lingakhethwa.Lapho izinga lokushisa lokushisa liphansi, isikhathi sokuphulukisa singanwetshwa ngokufanelekile.I-resin esetshenziswa esihlabathini esiboshwe i-phenolic resin.Izinzuzo zenqubo yokwenza umnyombo: ukusebenza kahle kwamandla;fluidity enhle;ikhwalithi enhle yendawo yomgogodla wesihlabathi (Ra = 6.3-12.5μm);ukumelana nomswakama oqinile we-sand core;ukugoqa okuhle nokuhlanza okulula kwama-castings.
1. Ukushisa kwesikhunta (isikhunta).
Izinga lokushisa lesikhunta lingenye yezinto eziyinhloko ezithinta ukushuba namandla engqimba yegobolondo, ngokuvamile elawulwa ku-220～260℃
2. Ukucindezela kwesihlabathi sokudubula nesikhathi
Isikhathi sokudutshulwa kwesihlabathi ngokuvamile silawulwa ku-3～10s.Uma isikhathi sisifushane kakhulu, isikhunta sesihlabathi (core) asikwazi ukwakhiwa.Ukucindezela kwesihlabathi sokudubula ngokuvamile kumayelana ne-0.6MPa;lapho ingcindezi iphansi kakhulu, kulula ukubangela ukudubula okunganele noma ukuxega.Isikhathi sokuqina: Ubude besikhathi sokuqina buncike ikakhulukazi ebukhulu besikhunta sesihlabathi (umgogodla) kanye nezinga lokushisa lesikhunta, ngokuvamile elizungeze ama-60-120s.
Njengamanje, imikhiqizo yethu eyinhloko ukufakwa kwepayipi lensimbi okuthambile, izinsimbi zamashubhu, izixhumi zefreyimu, ama-hose hose couplings, ama-double bolt clamps, ama-clamps epayipi lebhawodi elilodwa, ama-camlock couplings, ama-couplings asheshayo, umzimba we-conduit, izingono ze-KC, ama-hose menders kanye namakhulu angaphezu kwamakhulu imikhiqizo ongayikhetha.Siyakwamukela ku-Donghuan Malleable Iron Casting ukuze uthole imibuzo, sizokunikela ngobuqotho enkonzweni yakho.
Isikhathi sokuthumela: Dec-22-2021
