Ubushinwa ASTM A53 Gr.B Umuyoboro Ushyushye wa Carbone Utagira Umuyoboro
Ibisobanuro bigufi:
Uyu muyoboro wa Alloy Steel hamwe na 12cr1MOV Ibikoresho ni umuyoboro wicyuma udafite kashe ushobora gukoreshwa muri peteroli, imiti, ingufu zamashanyarazi hamwe nogukoresha amashyiga.Ifite ibiranga kurwanya ubukonje, kurwanya ubushyuhe no kurwanya ruswa.12Cr1MoV ni ubwoko bwumuyoboro.Intego nyamukuru nugukora ibyuma byubatswe mubyuma.
Twisunze ihame rya "ubuziranenge, serivisi, gukora neza no kuzamuka", twabonye ibyiringiro no gushimwa kubakiriya bo mu gihugu ndetse n’amahanga ku Bushinwa ASTM A53 Gr.B Umuyoboro Ushyushye wa Carbone Umuyoboro wicyuma, Kubindi bibazo cyangwa ushobora kugira ikibazo kijyanye nibicuruzwa byacu, menya neza ko udatinda kuduhamagara.
Twisunze ihame rya "ubuziranenge, serivisi, gukora neza no gutera imbere", twabonye ibyiringiro no gushimwa kubakiriya bo mu gihugu ndetse n’amahanga kuriUmuyoboro w'icyuma n'Ubushinwa, Turimo kwagura umugabane mpuzamahanga ku isoko dushingiye ku bintu byiza, serivisi nziza, igiciro cyiza no gutanga ku gihe.Nyamuneka twandikire igihe icyo aricyo cyose kugirango ubone ibisobanuro byinshi.
Ubushyuhe bwa serivisi ni 580 and, kandi icyuma gisabwa kugira imbaraga zo kwihanganira ubushyuhe bwo hejuru.Isahani yicyuma itangwa muburyo busanzwe kandi bwitondewe.Umuyoboro wa 12Cr1MoVG ushingiye ku cyuma cyiza cyo mu rwego rwo hejuru cya karubone, kandi ikintu kimwe cyangwa byinshi byongeweho byongeweho mu buryo bukwiye kugira ngo bitezimbere imashini, gukomera no gukomera kwicyuma.Ibicuruzwa bikozwe mubyuma mubisanzwe bisaba kuvura ubushyuhe (bisanzwe cyangwa kuzimya no gutuza);Ibice nibigize bikozwe mubisanzwe bikenera gukenera kuzimya no gutwarwa cyangwa kuvura imiti yo hejuru (carburizing, nitriding, nibindi), kuzimya hejuru cyangwa kuzimya inshuro nyinshi mbere yo kuyikoresha.Kubwibyo, ukurikije ibinyabuzima bitandukanye (cyane cyane ibirimo karubone), uburyo bwo gutunganya ubushyuhe nuburyo bukoreshwa, ibyuma nkibi birashobora kugabanywa hafi ya karubasi, kuzimya no gutwarwa nicyuma cya nitride.
Ubwa mbere, irashobora gukoreshwa 100%, kuzigama ingufu no kurengera ibidukikije.
Icya kabiri, ifite plastike ndende cyane kandi irashobora gukoreshwa mugukora kabiri no kuyitunganya.
Icya gatatu, ifite ubushyuhe bwiza bwubushyuhe hamwe nubushyuhe bwo hejuru bwo hejuru.
Icya kane, ifite imbaraga zo kurwanya okiside no kurwanya ruswa.
Icya gatanu, ifite imikorere ikonje kandi ishyushye.
12R molybdenum 0.25-0.35, alum 0.15-0.30, nibindi
Ubwa mbere, ikoreshwa cyane cyane mugukora imiyoboro yumuvuduko ukabije wogukoresha ubushyuhe bwo hejuru yubushyuhe bwamazi hamwe numuvuduko mwinshi kandi hejuru.
Icya kabiri, ikoreshwa cyane muri superheater, imitwe hamwe numuyoboro wingenzi wumuvuduko ukabije wimbere mu gihugu, umuvuduko ukabije wumuyaga hamwe nubushyuhe bwamashanyarazi.
Icya gatatu, imiyoboro minini ya diametre ikoreshwa cyane cyane nkimitwe hamwe nuyoboro nyamukuru wamazi ufite ibipimo biri munsi ya 565 ℃.
Ubwa mbere, kuzunguruka bishyushye (gukuramo ibyuma bidafite ibyuma) bigenda:
Umuyoboro uzunguruka → gushyushya → gutobora → kuzunguruka kuzunguruka, guhora kuzunguruka cyangwa gusohora → gukuramo imiyoboro → gupima (cyangwa kugabanya) → gukonjesha → bilet → kugorora test ikizamini cya hydrostatike (cyangwa gutahura inenge) → ikimenyetso → ububiko.
Icya kabiri, gushushanya gukonje (kuzunguruka) ibyuma bitagira ibyuma bitembera:
Umuyoboro uzengurutswe → gushyushya → gutobora → umutwe → annealing → gutoranya → gusiga amavuta (gusya umuringa) → gushushanya byinshi bikonje (gukonjesha gukonje)

Twisunze ihame rya "ubuziranenge, serivisi, gukora neza no gutera imbere", twabonye ibyiringiro no gushimwa kubakiriya bo mu gihugu ndetse n’amahanga ku Bushinwa STM A53 Gr.B Umuyoboro Ushyushye wa Carbone Umuyoboro wicyuma, Kubindi bibazo cyangwa ushobora kugira ikibazo kijyanye nibicuruzwa byacu, menya neza ko udatinda kuduhamagara.
Umuyoboro w'icyuma n'Ubushinwa, Turimo kwagura umugabane mpuzamahanga ku isoko dushingiye ku bintu byiza, serivisi nziza, igiciro cyiza no gutanga ku gihe.Nyamuneka twandikire igihe icyo aricyo cyose kugirango ubone ibisobanuro byinshi.
