LR Icyiciro cya E Icyuma Cyicyuma

Icyuma cyo mu nyanja bivuga ibyuma byubatswe bikoreshwa mu kubaka ubwato. Bifatwa nk'urwego rwo mu nyanja kandi rugomba kuba rushobora kurwanya ingaruka mbi zangiza ibidukikije. Kugirango ubigereho, ibintu bidasanzwe bivanga byongewe kuri aya manota murwego rwo kurinda ruswa ya agaist.Mu gihe ibyuma byinshi bya karubone bidakwiranye n’ibidukikije byo mu nyanja, hari ibyuma byinshi byo mu nyanja byo mu nyanja byemejwe n’imiryango itandukanye yo kubaka ubwato.

Ibyuma byubatswe kubwato bigabanijwemo ibyiciro byimbaraga ukurikije imbaraga zabyo nkeya: imbaraga rusange zubaka ibyuma hamwe nimbaraga zikomeye zubaka. Icyuma cya Maine bivuga icyuma gishyushye kizengurutse cyakozwe hakurikijwe ibisabwa na societe ya classique yo kubaka inyubako zubwato.

Hano ku isi hose hari societe 9 zingenzi.

Icyiciro D, E (DH32, DH36, EH 32, EH 36)
Icyiciro cya D na E (harimo AH32 / 36, DH32, DH36, EH32, EH36) ibyuma byubaka ubwato bisaba ubukonje buke bwo hasi no gukora neza. Umusaruro ufite imbaraga nyinshi zubaka ibyuma byubaka bigomba kuba bisanzwe muburyo bwo kugenzura no kugenzura gukonjesha cyangwa gutunganya ubushyuhe hamwe nibikoresho byuzuye. Muri icyo gihe, ibyuma byimbere byimbere byamafaranga yatanzwe birasabwa kuba hejuru, cyane cyane ibiri muri S, P, N, 0 na H mubyuma bigomba kugenzurwa cyane.

Alloy Ibintu Byongeweho Kunoza Gukomera
Kugirango hamenyekane imikorere yicyapa gifite imbaraga nyinshi, hifashishijwe tekinoroji ya micro-alloying. Mugushyiramo Nb, V, Ti nibindi bintu bivanga mubyuma, bigahuzwa nuburyo bugenzurwa, ingano zinonosorwa kandi ubukana buratera imbere.
Icyerekezo cyiterambere cyubwato
Imbaraga nyinshi, ibisobanuro bihanitse, hamwe n’ubwato bunini n’umutekano, hamwe n’impinduka mu bisobanuro bifatika, ibisabwa ku bikoresho bisanzwe byo mu rwego rwa A bigenda bigabanuka buhoro buhoro, kandi n’ibisabwa ku mbaraga nini cyane biriyongera, bikaba byibanda mu mato manini. ya 5m z'ubugari. Isahani, uburebure bwa 200-300mm budasanzwe bwubwato.
