China OEM isiko spheroidal igraphite cast intsimbi iqokobhe ngundo iimveliso zokugalela ngeenkonzoCNC Machining, unyango lobushushu kunye nonyango lwangaphezulu.
Ukubunjwa kweqokobheInkqubo ikwabizwa ngokuba yinkqubo yokugalela yentlabathi eqatywe ngaphambili, ukubunjwa kweqokobhe elishushu okanye inkqubo yokugalela engundoqo. Izinto eziphambili zokubumba yintlabathi ye-phenolic resin efakwe ngaphambili, ebiza kakhulu kunesanti eluhlaza kunye ne-furan resin sand. Ngaphezu koko, le santi ayinakuphinda isetyenziswe.
I-Furan resin self-ukuqina kwesanti inkqubo yokugalela (inkqubo ye-nobake) isebenzisa i-furan resin egqunywe isanti ukwenza i-mold yokuphosa. Emva kokuxuba isanti yoqobo (okanye isanti ebuyisiweyo), intlaka ye-furan elulwelo kunye ne-catalyst engamanzi ngokulinganayo, kwaye uyigcwalise kwibhokisi engundoqo (okanye kwibhokisi yesanti), kwaye emva koko uyiqinise ukuze iqine ibe ngumbumba okanye i-mold kwibhokisi engundoqo (okanye isanti. ibhokisi) kwiqondo lokushisa. Emva koko i-mold casting okanye i-casting core yaqulunqwa, ebizwa ngokuba yi-self-hardening ebandayo-ibhokisi yokubumba (i-core), okanye indlela yokuziqinisa (core).
Ngenxa yokuba umngundo wenziwe kwiqondo lobushushu begumbi kwaye akukho mfuneko yokufudumeza, ukuziqinisa kwesanti kukwabizwa ngokuba yinkqubo yokuphosa yokubhaka. Indlela yokuziqinisa inokwahlulwa ibe yi-acid-catalyzed furan resin kunye ne-phenolic resin sand self-harding method, i-urethane resin sand self-harding method kunye ne-phenolic monoester self-harding method.
Njengesanti ebopha ibhokisi ebandayo ezenza lukhuni, isanti ye-furan resin yeyona ntlabathi yokuqala kwaye ngoku isetyenziswa kakhulu kwisiseko saseTshayina. Isixa se-resin esongeziweyo kwisanti yokubumba ngokuqhelekileyo yi-0.7% ukuya kwi-1.0%, kwaye isixa se-resin eyongezelelweyo kwisanti engundoqo ngokubanzi yi-0.9% ukuya kwi-1.1%. Umxholo we-aldehyde yasimahla kwi-furan resin ungaphantsi kwe-0.3%, kwaye ezinye iifektri ziye zehla ukuya ngaphantsi kwe-0.1%. Kwiziseko zase-China, isanti ye-furan ye-resin yokuziqinisa ifikelele kwinqanaba lamazwe ngamazwe kungakhathaliseki ukuba yinkqubo yokuvelisa kunye nomgangatho womphezulu we-castings.
Ductile cast iron, ekwabizwa ngokuba yi-nodular cast iron, spheriodal graphite cast iron or just SG iron for short, imele iqela lentsimbi. I-nodular cast iron ifumana i-graphite ye-nodular ngokusebenzisa i-spheroidization kunye nonyango lwe-inoculation, oluphucula ngokufanelekileyo iimpawu ze-mechanical of iron cast, ngokukodwa i-plastiki kunye nokuqina, ukuze ufumane amandla aphezulu kune-carbon steel.
I-Ductile iron castings inomsebenzi ongcono wokufunxa ukothuka kunekhabhoni yentsimbi, ngelixa i-carbon steel castings inokuqina okungcono kakhulu. Kwaye ukuya kuthi ga kwinqanaba elithile, i-ductile iorn castings inokuba nemidlalo ethile yokumelana nokunxiba kunye nomhlwa. Ke i-ductile iron casting ingasetyenziselwa ezinye izindlu zempompo okanye iinkqubo zokubonelela ngamanzi. Nangona kunjalo, kusafuneka senze izilumkiso zokuzikhusela zinganxibi kunye nomhlwa.
I-Ductile iron ayiyona nto enye kodwa iyinxalenye yeqela lezinto ezinokuveliswa ukuba zibe noluhlu olubanzi lweepropati ngokulawulwa kwe-microstructure. Uphawu oluqhelekileyo lweli qela lezinto eziphathekayo yimilo yegraphite. Kwiintsimbi ze-ductile, i-graphite ikwimo ye-nodules kunokuba i-flakes njengoko i-iron engwevu. Imilo ebukhali yeeflakes zegraphite zenza amanqaku oxinzelelo ngaphakathi kwe-matrix yesinyithi kunye nokumila okungqukuva kwamaqhuqhuva angaphantsi kangako, ngaloo ndlela kuthintela ukudalwa kweentanda kunye nokubonelela nge-ductility eyandisiweyo enika i-alloy igama layo. Ngokuqhelekileyo, ukuba i-iron ductile inokuhlangabezana neemfuno zakho, i-iron ductile inokuba lukhetho lwakho lokuqala, endaweni ye-carbon steel for castings yakho.

Izinto eziluncedo zeFuran Resin Coated Sanding Self-harding Molding Casting:
I-1) Ukuphucula ukuchaneka kwe-dimensional of castings kunye noburhabaxa bomphezulu.
I-2) Ukuqina kwe-mold (core) isanti ayifuni ukomisa, enokugcina amandla, kunye neenkuni ezingabizi kakhulu okanye iibhokisi zeplastiki eziphambili kunye neetemplates nazo zingasetyenziswa.
I-3) Isanti yokubumba i-self-hardnening kulula ukuyidibanisa kunye nokudilika, kulula ukuyicoca ii-castings, kunye nesanti esidala sinokuphinda sisetyenziswe kwaye sisetyenziswe kwakhona, esinciphisa kakhulu ubuninzi bomsebenzi wokwenza i-core, imodeli, ukuwa kwesanti, ukucoca kunye nezinye izixhumanisi, kunye kulula ukuqonda umatshini okanye i-automation.
I-4) Ubuninzi beqhekeza le-resin esantini kuphela i-0.8% ~ 2.0%, kwaye ixabiso elibanzi lezinto eziluhlaza liphantsi.
Ngenxa yokuba indlela yokuzenza lukhuni ineenzuzo ezininzi ezichazwe ngasentla, indlela yokuziqinisa ayisetyenziselwanga kuphela ukwenza i-core, kodwa isetyenziselwa ukubumba ukubunjwa. Ilungele ngokukodwa isiqwenga esisodwa kunye nokuveliswa kwebhetshi encinci, kwaye inokuvelisa isinyithi esityhidiweyo, isinyithi esityhidiweyo kunye ne-non-ferrous alloy castings. Amanye amaziko aseTshayina atshintshe ngokupheleleyo abumba isanti eyomileyo yodongwe, imibumbo yesanti yesamente, kunye nenxalenye yokubumba yesanti yeglasi yamanzi.
