Paunonzwa 'ductile iron casting foundry', pfungwa zhinji dzinosvetuka dzakananga kusimbi pachayo-iyo nodular graphite, iyo tensile simba specs. Ndiyo commodity talk. Iyo chaiyo nyaya, iyo inosarudza kana chikamu chinotora makore makumi maviri kana kukundikana mune maviri, inoitika munzvimbo dzegrey: gating system dhizaini, inoculation nguva, mabatiro aunoita mold mushure mekuzunza. Haisi yekungoita zvekukandira; zviri zveinjiniya chikamu chinoita kufanofungidzira pasi pekushushikana. Vatengi vakawandisa, kunyangwe mainjiniya, vanogadziriswa pamushumo wemakemikari uye vanopotsa zvese zvinoitika pakati pechoto uye yakapedzwa mashini kumusoro.
Iyo Foundry Floor iChemistry Lab, Asi kwete Nenzira Yaunofunga
Chokwadi, isu tinomhanya spectrometers. Ongororo yeladle yeyakajairwa ductile iron giredhi rakaita se65-45-12 rakatwasuka. Rova ako mazinga ekabhoni, silicon, magnesium. Mapepa acho akachena. Iyo chaiyo chemistry, kunyange zvakadaro, inoshanda uye yakashata. Iko kupera kweiyo magnesium post-inoculation. Une hwindo-dzimwe nguva angori maminetsi chete-kuti uise simbi yakarapwa muforoma iyo nodularizing mhedzisiro isati yaipa. Ndakaona kudirana uko zvese zvaive zvakakwana pabepa, asi kunonoka mumutsara kwakakonzera kudonha kushoma kwetembiricha uye kuzara kwakashata. Zvakaguma nei? Marginal graphite morphology muzvikamu zvakakora. Chikamu chinogona kupfuudza kuongororwa, asi hupenyu hwayo hwekuneta hunokanganiswa. Ndiko kuziva kusingataurwi mukushanda ductile iron casting foundry.
Apa ndipo panoturikira makumi emakore ekushanda, sepaQingdao Qiangsenyuan Technology Co., Ltd. (QSY), ichiturikira mukukosha. Neanopfuura makore makumi matatu ekukandira nekugadzira, vangangove vakadurura, nekuona, zvese. Kuyeuka kwesangano kwakakosha. Zvinoreva kuti vanodzora maitiro avo havasi kungotevera bhuku rekushandisa; vari kuona chitarisiko cherukova rwesimbi, ruzha rwesimbi ichirova cope, zvinyoro-nyoro zvinyoro zvingapotswa neautomated system. For ductile iron, aya macheki ekunzwa ndeye backup kune chiridzwa, yekupedzisira, gedhi remhando yemunhu.
Uye hazvisi zvesimbi chete. Ngatikurukurei zviumbwe. Pakuumbwa kwegoko, iyo QSY inonyora seyakakosha, jecha resin chemistry uye kurapa zvakangooma. Kutsauka kushoma muchikamu checatalyst kunogona kuita kuti goko riite brittle kana kupfava zvakanyanya. A brittle shell inogona kutsemuka panguva yekubata, ichikonzera mafins uye veining pakukanda. Goko rakapfava rinogona kukanganisa pasi pekupisa uye huremu hwesimbi, zvichitungamira kune dimensional kukukurwa.

Iko Kukandira Kunopera uye Machining Kunotanga (Kana, Musono Usingafanirwe Kuvapo)
Iyi imbwa huru yemhuka. A foundry anoshanda muvacuum kubva machining imhosva. Dhizaini yekukanda pateni inofanirwa kutarisira zvinodiwa neCNC chirongwa. Ko datum rekutanga richagadzikwa kupi? Pane yakachena, se-yakandwa pamusoro pekutanga clamping? Nzvimbo yemutsara wekuparadzanisa inogadzira mwenje unokanganisa kugadzirisa? Ndakagamuchira ma castings kubva kune dzimwe nzira dzakanaka dzakavambwa dzaive dzisingagoneki pasina kugadzira chimiro cheFrankenstein, zvese nekuti mainjiniya ekutanga haana kumbotaura nemuchina wemachina.
Kushanda kwakabatanidzwa seQSY's, kupa zvese kukanda uye CNC machining pasi pedenga remba, inogadzirisa izvi. Chitoro chavo chemaitiro chinogona kunge chiri mukukurukurirana nguva dzose nevanogadzira machining center programmers. Pavanenge vachigadzira mumhanyi uye riser system ye ductile iron casting, vari kufungawo kuti voiisa papi kuti ikwanise kubviswa pachigayo kwakachena, ichisiya nzvimbo inoshanda. Vanogona kuronga machining stock allowances ari echokwadi, kwete nhamba dzemabhuku chete. Iyi synergy ndipo paunochengetedza mari chaiyo uye nguva, uchidzivirira maemail asingaperi ekudzoka-ne-mberi pakati pevatengesi vakasiyana vachipomerana mhosva kune chikamu chisipo.
Muenzaniso unoshanda: hydraulic valve body yatakashanda pairi. Ndima dzomukati dzakanga dzakaoma, dzichida kunyatsojeka shell mold casting kutora geometry. Iyo yakakosha chisimbiso zviso zvaida Ra 0.8 kupera. The foundry that only cast it left heavy stock on the faces, which during Machining yakakonzera kuomarara uye kusaenzana kwechishandiso kupfeka nekuda kwekuoma kwepamusoro pedenga kubva kutonhora nekukurumidza. Iyo yakasanganiswa foundry-machinist, zvisinei, inogona kugadzirisa kutonhora maitiro (pamwe kushandisa insulating sleeve pane izvo zvinosimuka) kuti ive nechokwadi chehukukutu hwakafanana hwakadzama, uye wozoigadzira neyakagadzirirwa chishandiso nzira uye kuisa giredhi. Mhedzisiro yacho yaive kupera kurinani, hupenyu hurefu hwematurusi, uye chikamu chakavimbika. Aya haasi mashiripiti; iko kutaurirana kwakabikwa mukuita.
Mubvunzo weAlloy: Kana Ductile Iron Isina Kukwana
Ductile iron ibhiza rekushanda, asi iyo spec sheet haitauri nyaya yacho nguva dzose. Abrasion? 500 Brinell yakaomeswa ductile iron inogona kushanda. Asi wedzera kukanganisa? Ndiwo mutambo wakasiyana. Dzimwe nguva unofanirwa kupinda mune iwo akakosha alloys QSY inotaura-nickel-based kana cobalt-based alloys yekupfeka zvakanyanya uye ngura. Iko kugona kwekutanga pano kuri kutaura. Kunyunguduka nekudurura maaloyi aya kunoda marangiro echoto akasiyana, zvidzoreso zvemuchadenga, uye kazhinji nzira dzekudira dzakasiyana zvachose. Nzvimbo yekuwana yakagadzikana nezvinhu izvi kazhinji ine chirango chakaomarara chinobuda ropa kudzoka muchiyero chavo ductile iron shanda. Maprotocol avo ekudzora kusvibiswa achave akaomarara, kutarisa kwavo kupisa kwakanyanya.
Ndinoyeuka pombi yepombi yenzvimbo ine saline. Pfungwa yekutanga yaive austenitic ductile iron (Ni-Resist). Yakakanda zvakanaka, asi mukuyedzwa kwemunda, musanganiswa wechloride-induced corrosion uye cavitation erosion yakaidya nekukurumidza kupfuura zvaitarisirwa. Mushonga, wakagadzirwa nefoundry metallurgist, yaive shanduko kune duplex Stainless steel casting. Dambudziko rakazove rekudyisa simbi inodzikira zvakasiyana uye inowanzobvaruka nekupisa.
