MuriImyuka itwara igitutu of imiyoboro y'inganda, guta ibyumazikoreshwa cyane bitewe nubukungu bwazo nigishushanyo mbonera.Ariko, kubera ko inzira yo gukina igabanywa nubunini, uburebure bwurukuta, ikirere, ibikoresho fatizo nibikorwa byubwubatsi bwa casting, inenge zitandukanye zo gukina nka bliste, pore, cracks, shrinkage porosity, cavites shrinkage and inclusions bizagaragara muri casting, cyane cyane umusenyi wo guta.Gukora ibyuma kubindi.Kuberako ibintu byinshi bivanga mubyuma, niko ubukene bwamazi yicyuma gishongeshejwe, niko bishoboka cyane kubyara inenge.Kubwibyo, kumenya inenge no gushyiraho uburyo bwo gusudira bushyize mu gaciro, bwubukungu, bufatika kandi bwizewe bwo gusana kugirango barebe ko valve nyuma yo gusudira yujuje ibyangombwa byujuje ubuziranenge byabaye ikibazo rusange mugutunganya ubushyuhe n'imbeho.indangantego.Iyi ngingo irerekana uburyo bwo gusana bwo gusana hamwe nuburambe bwibintu byinshi bisanzwe bikozwe mu byuma (inkoni yo gusudira ihagarariwe nikirango gishaje).
Gukemura neza
1. Urubanza rutuzuye
Mu myitozo yo kubyaza umusaruro, inenge zimwe zo guterana ntizemerewe gusana gusudira, nko gucamo ibice, gucengera inenge (kwinjira munsi), ibinure byubuki, ibishishwa byumucanga bidashobora kuvaho, no kugabanya ububobere hamwe nubuso burenga santimetero kare 65, nibindi, nibindi, nibindi. nizindi nenge zikomeye zidashobora gusanwa nkuko byemejwe mumasezerano hagati yimpande zombi.Ubwoko bw'inenge bugomba gucibwa mbere yo gusana gusudira.
2. Gukuraho neza
Mu ruganda, imyuka ya karubone arc ikoreshwa muburyo bwo guhanagura inenge, hanyuma imashini isunika ikoreshwa muguhanagura ibice bifite inenge kugirango igaragaze urumuri rwinshi.Ariko mubikorwa byo gukora, nibyinshi gukoresha ibyuma bya karubone electrode hamwe numuyoboro mwinshi kugirango ukureho inenge, kandi ukoreshe inguni kugirango usya ibyuma.Mubisanzwe, guta inenge birashobora kuvaho ukoresheje <4mm-J422 electrode hamwe numuyoboro wa 160-180A kugirango ukureho inenge.Imashini isya inguni isya inenge muburyo bwa U kugirango igabanye gusudira.Inenge zavanyweho burundu, kandi gusana ubuziranenge nibyiza.
3. Gushyushya ibice bifite inenge
Kubyuma bya karubone hamwe na austenitike idafite ibyuma bidafite ibyuma, aho ubuso bwigice cyo gusana kiri munsi ya 65cm2 kandi ubujyakuzimu buri munsi ya 20% cyangwa 25mm yubugari bwa casting, kubanza kubanza kubanza ntibisabwa.Ariko, kumasaro ya pearlitike nka ZG15Cr1Mo1V na ZGCr5Mo, bitewe nuburyo bukomeye bwo gukomera kwibyuma no gucika byoroshye mugusudira gukonje, hagomba gukorwa ubushakashatsi.Igihe cyo gufata kigomba kuba byibuze 60min.Niba casting idashobora gushyukwa muri rusange, irashobora gushyuha kugeza kuri 300-350 ° C hamwe na ogisijeni-acetylene ahantu hafite inenge kandi ikagurwa na 20mm (kwitegereza umutuku wijimye ahantu hijimye), hamwe numuriro munini utagira aho ubogamiye. imbunda ikoreshwa mbere kubusembwa nuduce tuyikikije.Kuzenguruka uruziga vuba muminota mike, hanyuma wimuke buhoro muminota 10 (ukurikije ubunini bwinenge), kugirango inenge ishyushye rwose hanyuma ikosorwe vuba.
