Ductile cast iron resin wokutidwa ndi mchenga woponyedwa pamagalimoto onyamula katundu okhala ndi ma CNC machining services.
Utomoni wokutira mchenga chipolopolo nkhungu kuponyerandi njira yomwe mchenga wosakanikirana ndi utomoni wa thermosetting umaloledwa kuti ugwirizane ndi mbale yotentha yachitsulo yachitsulo, kotero kuti chipolopolo chopyapyala ndi cholimba cha nkhungu chimapangidwa mozungulira pattem. Kenako chipolopolocho chimachotsedwa pachitsanzocho ndipo cope ndi kukoka zimachotsedwa palimodzi ndikusungidwa mu botolo ndi zinthu zofunika kumbuyo ndipo chitsulo chosungunuka chimatsanuliridwa mu nkhungu.
Ma iron irons ndi ma aloyi achitsulo omwe amakhala ndi mpweya wopitilira 2%. Ngakhale zitsulo zotayidwa zimatha kukhala ndi mpweya wapakati pa 2 mpaka 6.67, malire enieni amakhala pakati pa 2 ndi 4%. Izi ndi zofunika makamaka chifukwa cha makhalidwe awo abwino oponya. Zitsulo zotayira zotuwa ndi zitsulo zotayira (zotchedwanso nodular cast iron kapena spheroidal graphite iron).
Pamene graphite ilipo ngati tinthu tating'ono, tozungulira, komanso togawanika bwino, zotsatira zake zofooketsa zimakhala zochepa ndipo zitsulo zoterezi zimakhala ndi ductility kwambiri. Chitsulo chamtunduwu chimatchedwa ductile kapena nodular iron kapena spheroidal graphite kapena chitsulo cha SG. Mtundu uwu wa graphite ukhoza kutheka powonjezera elemental magnesium kapena cerium kapena kuphatikiza zinthu ziwirizi ku chitsulo chosungunuka. Magnesium amawonjezeredwa ku 0.07 mpaka 0. 10% yotsatiridwa ndi kuwonjezera kwa ferro-silicon kuti apititse patsogolo graphitization. Panthawi yolimba, magnesium imathandizira kugawa ma graphite muzitsulo zonse.
Ductile cast iron imakhala ndi chiyerekezo champhamvu ndi kulemera, makina abwinoko komanso kukhudzika kwakukulu. Komanso, theductile zitsulo zigawo zikuluzikuluamapangidwa ndi kuponyera njira momwe kuwongolera bwino kwa mawonekedwe a gawo kungathe kukwaniritsidwa poyerekeza ndi kugwetsa dontho. Chifukwa chake, zinthu zambiri monga ma crank shafts ndi ndodo zolumikizira zomwe zimapangidwa nthawi zambiri ndi dontho ladontho zimasinthidwa kukhala zitsulo zopangira ma ductile iron.
Ubwino wa Resin Coated Sand Shell Mold Mold Casting:
1. Zojambula za nkhungu zomatira ndi utomoni nthawi zambiri zimakhala zolondola kwambiri kuposa mchenga. N'zotheka kupeza kulolerana kwa +0,25 mm kwa castings zitsulo ndi +0. 35 mm kwa imvi kuponyedwa chitsulo castings pansi yachibadwa ntchito. Pankhani ya nkhungu zololera bwino za chipolopolo, munthu atha kuzipeza mumtundu wa +0.03 mpaka +0.13 mm pazogwiritsa ntchito zina.
2. Malo osalala amatha kupezeka muzojambula za zipolopolo. Izi zimatheka makamaka ndi njere zocheperako zomwe zimagwiritsidwa ntchito. Mtundu wamtundu wa roughness ndi wa dongosolo la 3 mpaka 6 microns.
3. Ma angles okonzekera, omwe ali otsika kusiyana ndi mchenga, amafunikira mu nkhungu za zipolopolo. Kuchepetsa kwa ma angles okonzekera kungakhale kuchokera ku 50 mpaka 75%, zomwe zimapulumutsa kwambiri ndalama zakuthupi ndi ndalama zotsatila.
4. Nthawi zina, ma cores apadera amatha kuchotsedwa popanga zipolopolo. Popeza mchenga uli ndi mphamvu zambiri nkhungu imatha kupangidwa m'njira yoti zibowo zamkati zitha kupangidwa molunjika ndi kufunikira kwa zipolopolo.
5. Komanso, zigawo zoonda kwambiri (mpaka 0.25 mm) zamtundu wa mitu ya silinda yoziziritsidwa ndi mpweya zimatha kupangidwa mosavuta ndi chipolopolo cha chipolopolo chifukwa cha mphamvu yapamwamba ya mchenga yomwe imagwiritsidwa ntchito popanga.
6. Permeability wa chipolopolo ndi mkulu choncho palibe gasi inclusions zimachitika.
7. Mchenga wochepa kwambiri uyenera kugwiritsidwa ntchito.
8. Makina amatheka mosavuta chifukwa cha njira yosavuta yopangira zipolopolo.

▶ Njira Zopangira Mchenga Wopaka Utomoni:
✔ Kupanga Zitsulo. Mchenga wophimbidwa utomoni uyenera kutenthedwa pamapataniwo, chifukwa chake mawonekedwe achitsulo ndi chida chofunikira chopangira zipolopolo.
✔ Kupanga Nkhungu Yamchenga Yokutira kale. Pambuyo poyika zitsulo pamakina omangira, mchenga wa utomoni wophimbidwa kale udzawomberedwa pamapangidwewo, ndipo mutatha kutentha, kupaka utomoni kumasungunuka, kenako nkhungu zamchenga zimakhala chipolopolo cholimba cha mchenga ndi ma cores.
✔ Kusungunula Chitsulo cha Cast. Pogwiritsa ntchito ng'anjo zopangira, zidazo zimasungunuka kukhala madzi, ndiye kuti mankhwala achitsulo chamadzimadzi amayenera kufufuzidwa kuti agwirizane ndi manambala ndi maperesenti ofunikira.
✔ Kuthira Chitsulo. Chitsulo chosungunuka chikakwaniritsa zofunikira, chidzatsanuliridwa mu nkhungu za chipolopolo. Kutengera ndi zilembo zosiyanasiyana zamapangidwe oponya, zipolopolozo zimakwiriridwa mumchenga wobiriwira kapena zowunjikiridwa ndi zigawo.
✔ Kuwombera Kuwombera, Kupera ndi Kuyeretsa. Pambuyo pozizira ndi kulimba kwa zoponyera, zokwera, zitseko kapena zitsulo zowonjezera ziyenera kudulidwa ndikuchotsedwa. Kenako zitsulozo zimatsukidwa ndi zida zokopera mchenga kapena makina owombera. Pambuyo pogaya mutu wa gating ndi mizere yolekanitsa, mbali zomalizidwa zoponyedwa zimabwera, kudikirira njira zina ngati zikufunika.
▶ Njira Yakusewera Pambuyo pa Kuyimba

▶ Chifukwa Chake MukusankhaChithunzi cha RMCZa Zida Zoponyera za Shell Mold?
✔ Kulondola komanso kugwiritsa ntchito zinthu zambiri. Mudzalandira maukonde kapena pafupi-mawonekedwe-ukonde mankhwala pambuyo akamaumba zipolopolo, malingana ndi zofunikira za ogwiritsira ntchito mapeto, sipadzakhala kapena pang'ono Machining ndondomeko chofunika.
✔ Kuchita bwino pamtunda. Chifukwa cha zipangizo zamakono zopangira zojambulajambula, zojambula zochokera ku zipolopolo zimakhala ndi zowoneka bwino komanso zolondola kwambiri.
✔ Kusankha bwino koyenera poyerekeza ndi kupanga mchenga ndi ndalama. Zopangira zipolopolo zimakhala ndi ntchito yabwino komanso pamwamba kuposa kuponya mchenga, pomwe zimakhala zotsika mtengo kuposa kuyika ndalama moyenera.
