Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Insimbi empunga yangokwezifisoimikhiqizo yokukhipha isikhunta segobolondongezinkonzo zeCNC imishini, ukwelashwa kokushisa nokwelashwa kwendawo.

Insimbi empunga, noma insimbi empunga, iwuhlobo lwensimbi ekhonjiwe ene-graphite microstructure. Iqanjwe ngombala ompunga we-fracture eyakhayo. Insimbi empunga isetshenziselwa izindlu lapho ukuqina kwengxenye kubaluleke kakhulu kunamandla ayo aqinile, njengamabhulokhi amasilinda enjini evuthayo, izindlu zamaphampu, imizimba yamavalvu, amabhokisi kagesi, izisindo zokubala nezinsimbi zokuhlobisa. I-Gray cast iron's high thermal conductivity kanye nomthamo wekhanda othize kuvame ukusetshenziselwa ukwenza i-cast iron cookware nama-disc brake rotor.

Ukwakheka kwamakhemikhali okujwayelekile ukuze uthole i-graphitic microstructure yi-carbon engu-2.5 kuya ku-4.0% kanye ne-silicon engu-1 kuya ku-3%. I-graphite ingase ithathe u-6 kuya ku-10% wevolumu yensimbi empunga. I-silicon ibalulekile ekwenzeni insimbi empunga ngokuphambene nensimbi emhlophe, ngoba i-silicon iyisici sokuzinzisa i-graphite ku-cast iron, okusho ukuthi isiza i-alloy ukukhiqiza i-graphite esikhundleni se-iron carbides; ku-3% i-silicon cishe ayikho ikhabhoni ebanjwe ekuhlanganisweni kwamakhemikhali nensimbi.

I-graphite ithatha isimo se-flake enezinhlangothi ezintathu. Ngezilinganiso ezimbili, njengoba indawo epholile izovela ngaphansi kwesibonakhulu, ama-graphite flakes avela njengemigqa emihle. Amathiphu ama-flakes asebenza njengamanotshi akhona ngaphambili; ngakho-ke, i-brittle. Ukuba khona kwama-graphite flakes kwenza i-Grey Iron ikwazi ukusebenza kalula njengoba ijwayele ukuqhekeka kalula kuma-graphite flakes. I-iron empunga iphinde ibe namandla amahle kakhulu okumanzisa futhi yingakho isetshenziswa kakhulu njengesisekelo sokunyuswa kwamathuluzi omshini.

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.

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.
