China OEM inkambiso spheroidal graphite cast iron igobolondo cast isikhunta imikhiqizo nge amasevisiCNC imishini, ukwelashwa kokushisa nokwelashwa kwendawo.
Ukubunjwa kwegobolondoInqubo ibizwa nangokuthi inqubo yokuphonsa isihlabathi se-resin ehlanganiswe ngaphambili, ukubunjwa kwegobolondo elishisayo noma inqubo yokuphonsa okuyisisekelo. Impahla yokubumba eyinhloko isihlabathi se-phenolic resin esakhiwe ngaphambili, esibiza kakhulu kunesihlabathi esiluhlaza nesihlabathi se-furan resin. Ngaphezu kwalokho, lesi sihlabathi asikwazi ukuphinda sisetshenziswe.
I-Furan resin self-hard-harding sand casting process (inqubo ye-nobake) isebenzisa isihlabathi esimbozwe nge-furan resin ukwenza isikhunta sokuphonsa. Ngemva kokuxuba isihlabathi sokuqala (noma isihlabathi esibuyisiwe), i-liquid furan resin kanye ne-liquid catalyst ngokulinganayo, bese uyigcwalisa ebhokisini eliwumgogodla (noma ibhokisi lesihlabathi), bese uyiqinisa ukuze iqine ibe isikhunta noma isikhunta ebhokisini eliyinhloko (noma isihlabathi. box) ekamelweni lokushisa. Kwabe sekwakhiwa isikhunta sokuphonsa noma umgogodla wokuphonsa, okubizwa ngokuthi ukuziqinisa kwebhokisi elibandayo (umgogodla), noma indlela yokuziqinisa (umgogodla).
Ngenxa yokuthi isikhunta sakhiwe ekamelweni lokushisa futhi asikho isidingo sokushisa, ukukhishwa kwesihlabathi esiziqinisayo kubizwa nangokuthi inqubo yokukhipha okungabhaki. Indlela yokuziqinisa ingahlukaniswa nge-acid-catalyzed furan resin kanye ne-phenolic resin sand self-harding method, i-urethane resin sand self-harding method kanye ne-phenolic monoester self-harding method.
Njengesihlabathi esihlanganisa ibhokisi elibandayo eliziqinisayo, isihlabathi se-furan resin sisekuqaleni futhi okwamanje esisetshenziswa kakhulu isihlabathi esihlanganisayo sokwenziwa e-Chinese foundry. Inani le-resin elengezwe esihlabathini esibumbayo ngokuvamile lingu-0.7% kuya ku-1.0%, kanti inani le-resin eyengeziwe esihlabathini esiwumgogodla ngokuvamile lingu-0.9% kuya ku-1.1%. Okuqukethwe kwe-aldehyde yamahhala ku-furan resin kungaphansi kuka-0.3%, kanti ezinye izimboni zehle zaba ngaphansi kuka-0.1%. Ezindaweni ezisungulwe e-China, isihlabathi esiziqinisayo se-furan resin sesifinyelele ezingeni lamazwe ngamazwe ngaphandle kwenqubo yokukhiqiza kanye nekhwalithi engaphezulu ye-castings.
I-Ductile cast iron, ebizwa nangokuthi i-nodular cast iron, i-spheriodal graphite cast iron noma nje i-SG iron ngamafuphi, imele iqembu lensimbi ekhonjiwe. I-nodular cast iron ithola i-nodular graphite ngokusebenzisa i-spheroidization kanye nokwelashwa kwe-inoculation, okuthuthukisa ngokuphumelelayo izakhiwo zemishini yensimbi ekhonjiwe, ikakhulukazi i-plasticity nokuqina, ukuze uthole amandla aphezulu kune-carbon steel.
I-Ductile iron castings inokusebenza okungcono kokushaqeka kune-carbon steel, kuyilapho ukukhishwa kwe-carbon steel kunokushisela okungcono kakhulu. Futhi ngokwezinga elithile, i-ductile iorn castings ingaba nokudlala okuthile kokumelana nokugqwala. Ngakho-ke i-ductile iron casting ingasetshenziselwa ezinye izindlu zamaphampu noma izinhlelo zokuhlinzeka ngamanzi. Kodwa-ke, kusadingeka senze izinyathelo zokuzivikela ekugqokeni nasekugqwaleni.
I-Ductile iron ayiyona into eyodwa kodwa iyingxenye yeqoqo lezinto ezingakhiqizwa ukuze zibe nezinhlobonhlobo zezakhiwo ngokulawula i-microstructure. Isici esivamile esichazayo saleli qembu lezinto zokwakha ukuma kwegraphite. Kuma-ayina ama-ductile, i-graphite isesimweni samaqhuqhuva esikhundleni sama-flakes njengoba isensimbi empunga. Ukuma okucijile kwama-flakes e-graphite kudala amaphuzu okugxilisa ingcindezi ngaphakathi kwe-matrix yensimbi kanye nesimo esiyindilinga samaqhuqhuva sibe sincane kakhulu, ngaleyo ndlela kuvinjwe ukudalwa kwemifantu futhi kunikeze i-ductility ethuthukisiwe enikeza ingxubevange igama layo. Ngakho-ke, uma i-iron ductile ingahlangabezana nezidingo zakho, i-iron ductile ingaba yisinqumo sakho sokuqala, esikhundleni se-carbon steel for castings yakho.

Ubuhle be-Furan Resin Coated Sand Self-harding Molding Casting:
1) Thuthukisa ukunemba kwe-dimensional kokulingisa kanye nobukhulu obungaphezulu.
2) Ukuqina kwesihlabathi sesikhunta (core) akudingi ukomiswa, okungasindisa amandla, futhi amabhokisi ayisisekelo ezinkuni noma epulasitiki kanye nezifanekiso nawo angasetshenziswa.
I-3) Isihlabathi sokuzibumba esiziqinisayo kulula ukusihlanganisa futhi sigoqe, kulula ukusihlanza, futhi isihlabathi esidala singagaywa kabusha futhi sisetshenziswe kabusha, okunciphisa kakhulu ukuqina komsebenzi wokwenza ingqikithi, ukumodela, ukuwa kwesihlabathi, ukuhlanza nezinye izixhumanisi, kanye kulula ukubona imishini noma i-automation.
4) Ingxenye enkulu ye-resin esihlabathini ingu-0.8% ~ 2.0% kuphela, futhi izindleko eziphelele zezinto zokusetshenziswa ziphansi.
Ngenxa yokuthi indlela yokuzenza lukhuni inezinzuzo eziningi eziyingqayizivele ezibalulwe ngenhla, indlela yokuziqinisa ayisetshenziselwa ukwenza umgogodla kuphela, kodwa futhi isetshenziselwa ukubunjwa kokubunjwa. Ifaneleka ngokukhethekile ucezu olulodwa kanye nokukhiqizwa kwenqwaba encane, futhi ingakhiqiza insimbi ekhonjiwe, insimbi ekhonjiwe kanye ne-non-ferrous alloy castings. Ezinye izikhungo zaseShayina ziye zashintsha ngokuphelele isikhunta sesihlabathi esomile sobumba, isikhunta sesihlabathi sikasimende, futhi sashintsha ingxenye yesikhunta sesihlabathi sengilazi yamanzi.
