Gutera Ibikoresho Byibikoresho Byuma Byuma - Pores na Shrinkage Porosity

Hazabaho inenge muri casting iyo ari yo yose.Kubaho kw'izi nenge bizazana akaga gakomeye kihishe kumiterere yimbere ya casting.Gusana gusudira kugirango bikureho izo nenge mubikorwa byumusaruro nabyo bizazana umutwaro munini mubikorwa byo gukora..By'umwihariko, nkuko valve ari ntoya-shell ikozweho igitutu nubushyuhe, guhuza imiterere yimbere ni ngombwa cyane.Kubwibyo, inenge yimbere yabakinnyi ihinduka ikintu gikomeye kigira ingaruka kumiterere yabakinnyi.

Inenge zimbere zo guteramo valve zirimo cyane cyane imyenge, gushyiramo slag, kugabanuka kwinshi no gucamo.

Hano hazamenyekana imwe mu nenge nyamukuru ---- Imyenge no kugabanya ububobere

(1) Pore:

Imyenge ikorwa na gaze, hejuru yumwobo iroroshye, kandi ikorerwa imbere cyangwa hafi yubuso bwa casting, kandi imiterere ahanini ni umuzenguruko cyangwa ova.

Inkomoko nyamukuru ya gaze itanga imyenge ni:

NitNitorojeni na hydrogène byashongeshejwe mu cyuma bikubiye mu cyuma mu gihe cyo gukomera kwa casting, bigakora urukuta rw'imbere ruzengurutse cyangwa ova imbere rufite imyenge ya lisansi.

Ibintu bitose cyangwa bihindagurika mubikoresho byerekana icyitegererezo bizahinduka gaze kubera gushyuha, bikora imyenge ifite urukuta rwimbere rwijimye.

③ Mugihe cyo gusuka ibyuma, kubera umuvuduko udahungabana, umwuka uba ufite uruhare mu gukora imyenge.

Uburyo bwo kwirinda inenge za Pores:

①Mu gushonga, koresha bike cyangwa ntabikoresho byicyuma kibisi gishoboka, hanyuma uteke nibikoresho byumye na salle.

SteelIcyuma gishongeshejwe kigomba kurekurwa ku bushyuhe bwinshi kandi kigasukwa ku bushyuhe buke, kandi ibyuma bishongeshejwe bigomba gutuza neza kugira ngo byorohereze gaze.

Design Igishushanyo mbonera cyibisuka bigomba kongera umutwe wumuvuduko wicyuma gishongeshejwe kugirango wirinde uruhare rwa gaze, kandi ugashyiraho inzira ya gaze yubukorikori kugirango ibe yuzuye.

MaterialIbikoresho byo kubumba bigomba kugenzura ibirimo amazi n’ibyuka bya gaze, bikongerera umwuka umwuka, kandi umucanga wumucanga hamwe numusenyi bigomba gutekwa no gukama bishoboka.

(2) Kugabanya akavuyo (kurekura):

Numuzingi uhuza cyangwa udahuzagurika cyangwa uruzitiro rudasanzwe (cavity) imbere muri casting (cyane cyane ku gishyushye gishyushye), hamwe imbere imbere hafite ibara ryijimye.Ibinyampeke ni binini, cyane cyane dendrite, kandi bigateranira ahantu hamwe cyangwa henshi, kandi kumeneka biroroshye kugaragara mugihe cya hydraulic.

Impamvu yo kugabanuka kwimyanya (irekuye):

ingano iragabanuka iyo icyuma kimaze gukomera kiva mumazi kijya kumera.Kugabanuka kwimyanda yibyuma biterwa ahanini nubugenzuzi budakwiye bwo gukurikiranwa gukurikiranye, bishobora guterwa no gushiraho ibyago bitari byo, ubushyuhe bwinshi bwibyuma bishongeshejwe, hamwe no kugabanuka kwicyuma kinini.

Uburyo bwo gukumira imyenge igabanuka (irekuye):

Shushanya ubuhanga bwa sisitemu yo guteramo kugirango ibyuma bishongeshejwe bikomere bikurikiranye, kandi igice cya mbere gikomeye kigomba kongerwaho nicyuma gishongeshejwe.

Gushiraho neza kandi mu buryo bushyize mu gaciro ibyago, inkunga, hamwe nicyuma gikonje cyimbere ninyuma kugirango tumenye neza.

HenIyo gusuka ibyuma bishongeshejwe, amaherezo gusuka hejuru ya riser bifasha mukugenzura ubushyuhe no kugaburira ibyuma byashongeshejwe, no kugabanya kubyara imyenge igabanuka.

④ Kubijyanye no gusuka umuvuduko, gusuka umuvuduko muke birafasha cyane gukomera kuruta gusuka byihuse.

TemperatureUbushyuhe bwo gusuka ntibugomba kuba hejuru cyane.Icyuma gishongeshejwe kirekurwa ku bushyuhe bwinshi kandi kigasukwa nyuma yo kwikuramo, bifasha kugabanya imyenge igabanuka.
