Nkibikorwa gakondo byo gukora, gutunganya umusenyi biracyafite umwanya wingenzi mugutanga umusaruro.Nubwo furan yibikorwa byo gukora, inzira ikonje yibikorwa hamwe nibindi bikorwa bigenda bitera imbere kandi bigashyirwa mubikorwa, inzira yacyo yo gukora iracyakoreshwa cyane mubikorwa bitandukanye byo gutara bitewe nubwiza bwayo buhebuje, imbaraga nyinshi hamwe nubushyuhe bwumuriro, hamwe nigihe kinini cyo kubika.Biracyagoye gusimbuza inganda zimwe nkibice bya hydraulic, ibishishwa bya turbine nizindi nganda zo mu rwego rwo hejuru.
Ibiranga:
imbaraga zikwiye;amazi meza, ibishushanyo byumucanga hamwe numusenyi wumusaruro byakozwe bifite imiterere isobanutse nuburyo bwuzuye, kandi birashobora kubyara umusenyi utoroshye;ubwiza bwubuso bwumucanga (intangiriro) nibyiza, ububobere bwubuso bushobora kugera kuri Ra = 6.3 ~ 12.5μm, kandi uburinganire bwibipimo bushobora kugera kurwego rwa CT7 ~ CT9;gusenyuka neza, kandi gukina biroroshye gusukura.
Igipimo cyo gusaba
Irashobora gukoreshwa mugukora ibishushanyo byombi hamwe numusenyi.Ibishushanyo cyangwa ingirangingo zirashobora gukoreshwa zifatanije cyangwa hamwe nizindi musenyi (cores);ntishobora gukoreshwa gusa mu guta ibyuma bikurura imbaraga cyangwa guta umuvuduko muke, ariko irashobora no gukoreshwa mu guta umucanga wicyuma no gushiramo centrifugal;ntishobora gukoreshwa gusa mu gukora ibyuma bikozwe mu byuma na fer idafite ferrous, ariko no mu gukora ibyuma.
ibihimbano
Mubisanzwe bigizwe nibikoresho byangiritse, binders, imiti ikiza, amavuta hamwe ninyongera zidasanzwe.
(1) Ibikoresho bivunika nibintu byingenzi bigize.Ibisabwa kubikoresho byangiritse ni: guhindagurika cyane, guhindagurika kwinshi, ugereranije ugereranije nuduce, bikomeye, nibindi.Ibisabwa ku mucanga wa silika ni: ibirimo byinshi bya SiO2 (ibyuma bikozwe mu byuma na ferrous alloy casting bisaba hejuru ya 90%, naho ibyuma bikozwe mu cyuma bisaba hejuru ya 97%);ibyondo ntibirenze 0.3% (kumucanga usukuye) - [ibyondo byumucanga wogejwe ni munsi;ingano yubunini ① itangwa kuri 3 kugeza 5 nimero yegeranye;imiterere yibice irazengurutse, kandi impande zinguni ntizigomba kurenza 1.3;agaciro ka acide ntabwo kari munsi ya 5ml.
(2) Ubusanzwe fenolike ikoreshwa nka binder.
(3) Hexamethylenetetramine isanzwe ikoreshwa nk'umuti ukiza;calcium stearate isanzwe ikoreshwa nka lubricant, ikoreshwa mukurinda guhunika no kongera amazi.Igikorwa nyamukuru cyinyongera nukuzamura imikorere yumucanga utwikiriwe.
. stearate 5-7 (uburemere bwa resin), inyongera 0.1-0.5 (uburemere bwumucanga mbisi).1: 2) 10-15 (uburemere bwa resin), Kalisiyumu stearate 5-7 (uburemere bwa resin), inyongera 0.1-0.5 (uburemere bwumucanga mbisi).
Inzira yumusaruro
Igikorwa cyo kwitegura gikubiyemo ahanini gukonjesha, gutwika ubushyuhe no gushyushya.Kugeza ubu, umusaruro hafi ya yose ufata ibishishwa bishyushye.Igishishwa gishyushye ni ugushyushya umucanga mbisi ku bushyuhe runaka, hanyuma ukavanga hanyuma ukabisiga hamwe na resin, urotropine aqueous solution hamwe na calcium stearate, hanyuma bikonje, kumenagura na ecran.Bitewe no gutandukanya formula, inzira yo kuvanga iratandukanye.Kugeza ubu, mu Bushinwa hari ubwoko bwinshi bw'imirongo itanga umusaruro.Hariho imirongo igera kuri 2000 ~ 2300 yumurongo utanga umusaruro hamwe no kugaburira intoki, kandi hariho imirongo igera kuri 50 igenzurwa na mudasobwa yumurongo utanga umusaruro, utezimbere neza umusaruro kandi uhagaze neza.Kurugero, umurongo utanga amashusho yerekana amashusho ya xx Casting Co., Ltd afite igihe cyo kugaburira igihe cyo kugaburira neza 0.1 isegonda, ubushyuhe bwo kugenzura ubushyuhe bwa 1/10 and, kandi leta ivanga umucanga irashobora kugaragara igihe cyose binyuze kuri videwo , hamwe nubushobozi bwo gukora toni 6 / isaha.
Ibyiza byimikorere
Amazi meza
Yashizweho na resin ikomeye kandi igaragara nkumucanga wumye.Amazi meza cyane ninyungu zayo nini, akwiriye cyane cyane kumusenyi muto kandi muto.
Ubwiza buhebuje bwubutaka bwumucanga
Ihujwe no guturika kurasa, kandi hejuru yumusenyi wumucanga ni mwinshi kandi woroshye, ushobora kunoza neza kurangiza kurasa.
Igiciro gito cyo gukora shell core
Ifite ahantu hanini ho gushonga kandi irashobora gukoreshwa mugukora igikonoshwa, hamwe no gukoresha umucanga muke, igiciro gito hamwe no guhumeka neza.
Imbaraga nyinshi hamwe nubushyuhe bwumuriro
ukoresheje thermoplastique phenoline resin, ifite imbaraga nyinshi hamwe nubushyuhe bwumuriro, itanga inyungu zidasanzwe mugukoresha ibice bimwe binini kandi binini.
Igihe kirekire cyo kubika umucanga
Imisemburo ya alkaline ikoreshwa mu mucanga utwikiriwe ni hydrophobique, intandaro yumucanga ifite imbaraga zo kurwanya ubushuhe, nta bisabwa bidasanzwe kubibikwa, kandi nta kugabanuka gukomeye kwinshi nyuma yo kubikwa igihe kirekire.
Urwego runini rwa porogaramu
Umusenyi utwikiriwe neza urakwiriye guterwa ibikoresho byose byuma.
