Inenge Zisanzwe Zitera: Impamvu nuburyo bwo kwirinda

Mubikorwa byo gukina casting, inenge nibintu bisanzwe bishobora kuvamo igihombo gikomeye kubabikora. Gusobanukirwa ibitera no gukoresha uburyo bwiza bwo gukumira ni ngombwa kugirango ubuziranenge bufite ireme. Hano haribisanzwe bikunze kugaragara hamwe nibitera nibisubizo byabyo.

1. Ububabare (Bubbles, Choke Hole, Pocket)

Ibiranga: Ububabare muri casting bugaragara nkibinogo biri hejuru, bitandukanye muburyo butandukanye uhereye kumuzingo kugeza bidasanzwe. Imyenge myinshi irashobora gukora umufuka wumwuka munsi yubuso, akenshi bumeze nkamapera. Ibinogo bya Choke bikunda kugira imiterere idahwitse, idasanzwe, mugihe imifuka isanzwe ihujwe nubuso bworoshye. Ibinure byoroshye birashobora kugaragara muburyo bugaragara, mugihe pinholes igaragara nyuma yo gutunganya imashini.

Impamvu:

• Ubushyuhe bwo gushyushya ubushyuhe buri hasi cyane, bigatuma ibyuma byamazi bikonja vuba iyo bisutswe.
• Igishushanyo mbonera kibura umunaniro ukwiye, bivamo imyuka yafashwe.
• Irangi ridakwiye cyangwa gutwikira hamwe no guhumeka nabi.
• Imyobo n'ibinogo biri mu cyuho bitera kwaguka byihuse, bigatera umwobo.
• Ubuso bwububiko bwububiko bwangiritse kandi ntibusukuye.
• Ibikoresho bibisi (cores) bibikwa nabi cyangwa ntibishyushye mbere yo kubikoresha.
• Kugabanya nabi agent cyangwa ibipimo bitari byo nibikorwa.

Uburyo bwo kwirinda:

• Shyushya neza ibishushanyo kandi urebe neza ko (nka grafite) bifite ingano zingana zingana zo guhumeka.
• Koresha uburyo bwo guterera kugirango uteze imbere no kugabura.
• Bika ibikoresho bibisi ahantu humye, bihumeka kandi ushushe mbere yo kubikoresha.
• Hitamo uburyo bwiza bwo kugabanya (urugero, magnesium).
• Igenzura ubushyuhe busuka kugirango wirinde gukonja vuba cyangwa gushyuha.

2. Kugabanuka

Ibiranga: Inenge zigabanuka ni umwobo utagaragara ugaragara hejuru cyangwa imbere muri casting. Kugabanuka gake bigizwe nintete zidatatanye kandi akenshi bibaho hafi yabiruka, risers, ibice byimbitse, cyangwa uduce dufite ubugari butandukanye bwurukuta.

Impamvu:

• Ubushyuhe bwububiko ntibushigikira gukomera.
• Guhitamo ibifuniko bidakwiye, cyangwa ubunini butaringaniye.
• Imyanya yo gutoranya itariyo muburyo bubi.
• Igishushanyo mbonera cyisuka riser, biganisha ku kuzuza ibyuma bidahagije.
• Gusuka ubushyuhe buri hasi cyane cyangwa hejuru cyane.

Uburyo bwo kwirinda:

• Ongera ubushyuhe bwubushyuhe kugirango ushyigikire ndetse no gukomera.
• Hindura umubyimba wuzuye kandi urebe ko ushyira mubikorwa.
• Koresha uburyo bwaho bwo gushyushya cyangwa kubika kugirango wirinde kugabanuka kwaho.
• Shyira mubikorwa bishyushye byumuringa cyangwa gukonjesha kugirango ugabanye igipimo cyo gukonja.
• Shushanya imirasire mubibumbano cyangwa ukoreshe amazi kugirango wihute.
• Koresha ibice bikonjesha biva mu cyuho kugirango bikomeze.
• Ongeraho ibikoresho byingutu kuri risers no gushushanya sisitemu yo kwinjiza neza.

3. Ibinogo bya Slag (Flux Slag na Metal Oxide Slag)

Ibiranga: Umwobo wa Slag ni umwobo wijimye cyangwa wijimye muri casting, akenshi wuzuyemo slag cyangwa ibindi bihumanya. Bashobora kuba bafite imiterere idasanzwe kandi mubisanzwe usanga hafi yabiruka cyangwa guta inguni. Flux slag irashobora kugorana kuyimenya muburyo bwambere ariko igaragara nyuma yo kuyikuraho. Oxide slag ikunze kugaragara mumarembo ya mesh hafi yubuso, rimwe na rimwe muri flake cyangwa ibicu bidasanzwe.

Impamvu:

• Uburyo butari bwo bwo gushonga no gushiramo, harimo sisitemu mbi ya gating.
• Ifumbire ubwayo ntabwo isanzwe itera umwobo; gukoresha ibyuma bishobora gufasha kwirinda iyi nenge.

Uburyo bwo kwirinda:

• Shushanya amarembo ya sisitemu hamwe nibisobanuro hanyuma utekereze gukoresha cast fibre muyunguruzi.
• Koresha uburyo bwo gusuka bugabanutse kugirango ugabanye gushiraho.
• Hitamo uburyo bwiza bwo guhuza ibikoresho kandi ukomeze kugenzura ubuziranenge.

Mugusobanukirwa nizo nenge zisanzwe no gukurikiza uburyo bwasabwe bwo gukumira, ibishingwe birashobora kuzamura ubwiza bwumusaruro no kugabanya amakosa ahenze. Komeza ukurikirane igice cya 2, aho tuzareba izindi nenge zisanzwe za casting hamwe nibisubizo byazo.
