imiyoboro ya ASTM A334 ni imiyoboro ya karuboni n'icyuma cya alloy yagenewe gukoreshwa mu bushyuhe buke kandi ikorwa hakoreshejwe uburyo budafite umugozi kandi busudiye.
Ingano zimwe na zimwe z'ibicuruzwa zishobora kutaboneka hakurikijwe ibi bisobanuro kuko ubunini bw'inkuta zikomeye zigira ingaruka mbi ku miterere y'ingaruka ku bushyuhe buke.
Ishyirwa mu byiciro ry'amanota
ASTM A334 ikubiyemo imiterere myinshi y’ahantu hashyuha cyane.
Icyiciro cya 1, Icyiciro cya 3, Icyiciro cya 6, Icyiciro cya 7, Icyiciro cya 8, Icyiciro cya 9, n'Icyiciro cya 11.
Amanota yaumuyoboro w'icyuma cya karuboniniIcyiciro cya 1naIcyiciro cya 6.
Amanota ajyanye na yo kuriimiyoboro y'icyuma cy'arundo ni iy'icyiciro cya 3, iy'icyiciro cya 7, iy'icyiciro cya 8, iy'icyiciro cya 9, n'iy'icyiciro cya 11.
Buri cyiciro cy'icyuma gifite imiterere yacyo yihariye y'ibinyabutabire n'ibisabwa ku miterere ya mekanike, ndetse n'ibipimo ntarengwa by'ubushyuhe bigomba kuzuzwa.
Uburyo bwo gukora
Imiyoboro igomba gukorwa naumushororocyangwa ikora ku buryo bwikorainzira yo gusudiranta cyuma cyongewemo mu gikorwa cyo gusudira.
Uburyo bwo kuvura ubushyuhe
Icyiciro cya 1, 3, 6, 7, na 9
Shyira ubushyuhe bungana na dogere selisiyusi 845 hanyuma ukonjeshe mu kirere cyangwa mu cyumba gikonjesha cy'itanura rigenzurwa n'ikirere.
Niba bikenewe ko habaho gupima, bizakenera kuganirwaho.
Ku bijyanye n'ibipimo byavuzwe haruguru by'imiyoboro y'icyuma idakora neza gusa:
Ongera ushyushye kandi ugenzure ubushyuhe bw'imikorere ishyushye n'ubushyuhe bw'imikorere ishyushye kugeza ku bushyuhe bwo kurangiza buri hagati ya 1550 - 1750 °F [845 - 955℃] hanyuma ukonjeshe mu itanura rigenzurwa kuva ku bushyuhe bwa mbere butari munsi ya 1550 °F [845 °C].
Icyiciro cya 8
Hitamo uburyo ubwo aribwo bwose muri ubu bukurikira bwo kuvura ubushyuhe.
Yazimye kandi irangwa n'imitekerereze;
Ifite Imyitwarire Ibiri Isanzwe n'Iy'Umuco.
Icyiciro cya 11
Niba umuguzi n'umutanga serivisi bagomba gushyiraho imiyoboro y'amazi yo mu cyiciro cya 11, ni amasezerano hagati yabo.
Iyo imiyoboro ya Grade 11 ifunguwe igomba kuba iri hagati ya 1400 - 1600℉[760 - 870°C].
Ibikubiye mu ikoranabuhanga rya ASTM A334
Ku byuma byo mu rwego rwa 1 cyangwa 6, ntibyemewe gutanga ingero zo guhuza ibintu bitari ibyo bisabwa byemewe. Ariko, byemerewe kongeramo ibintu bikenewe kugira ngo icyuma gifunguke.
Ibizamini bya ASTM A334 bya Mekanike
Ibisabwa ku miterere y’imashini ntibireba imiyoboro iri munsi ya santimetero 3.2 z’umurambararo wo hanze kandi ifite ubugari bw’urukuta buri munsi ya santimetero 0.015 z’umurambararo.
1. Umutungo wo gukurura
Uburebure buke bwabazwe kuri buri gabanywa rya santimetero 0.80 mu bugari bw'urukuta:
Ku miyoboro iri munsi ya 12.7 mm y'umurambararo wo hanze, agaciro k'uburebure katanzwe ku bipimo by'imirongo kagomba gukoreshwa.
2. Ibizamini by'Ingaruka
Hitamo ubushyuhe bukwiye n'imbaraga z'ingaruka zijyanye nabyo hashingiwe ku rwego n'ubugari bw'urukuta.

4. Ikizamini cyo Kugabanya Ubushyuhe
Ikizamini kimwe cyo gupima gikwiye gukorwa ku bipimo bivuye ku mpera ya buri gice cy’umuyoboro warangiye ariko ntabwo ari icyo gukoreshwa mu ikizamini cyo gupima cyangwa icyuma gipima.
5. Ikizamini cy'Umucyo (Imiyoboro Idafite Umushongi)
Ikizamini kimwe cyo gupima kigomba gukorwa ku bipimo bivuye ku mpera ya buri gice cy’umuyoboro warangiye, ariko ntabwo ari cyo cyakoreshejwe mu ikizamini cyo gupima.
6. Ikizamini cya Flange (Imiyoboro Isutswe)
Ikizamini kimwe cya flange kigomba gukorwa ku bipimo bivuye ku mpera ya buri muyoboro umwe warangiye wa buri gice, ariko ntabwo ari cyo cyakoreshejwe mu ikizamini cyo gufunga.
7. Ikizamini cyo Gusubira inyuma mu buryo bworoshye
Ku miyoboro ishongeshejwe, hagomba gukorwa ikizamini kimwe cyo gufunga inyuma ku rugero rumwe kuri buri metero 460 z'umuyoboro urangiye.
Ikizamini cy'amashanyarazi gishingiye ku mazi cyangwa kidasenya
Buri muyoboro ugomba gupimwa amashanyarazi nta kuyangiza cyangwa gupimwa hifashishijwe amashanyarazi hakurikijwe Ibisobanuro A1016/A1016M.
Porogaramu zo gukoresha umuyoboro w'icyuma wa ASTM A334
Ikoreshwa cyane cyane mu gutwara ibinyabutabire cyangwa imyuka nka gaze karemano, peteroli, n'ibindi binyabutabire ku bushyuhe buke.
1. Sisitemu zo gukwirakwiza imiyoboro ya Cryogenic: ikoreshwa cyane mu kubaka imiyoboro yo gutwara amazi aturuka ku mazi (urugero: gaze karemano ivanze n'amazi, azote y'amazi). Bitewe n'ubushobozi bwayo bwiza bwo kuzura, irashobora kugumana imbaraga n'ubukomere mu bushyuhe buri hasi cyane.
2. Ibikoresho bihindura ubushyuhe n'ibikonjesha: Ibikoresho bihindura ubushyuhe n'ibikonjesha bishobora gukoreshwa neza mu gukonjesha cyangwa gushyushya ibikoresho, cyane cyane mu nganda zikora imiti n'ibikomoka kuri peteroli.
3. Imiyoboro y'umuvuduko: ishobora kandi gukoreshwa mu gukora imiyoboro y'umuvuduko yagenewe ibikorwa byo gukwirakwiza amazi. Iyi miyoboro ishobora gukoreshwa mu kubika imiti ihumanya cyangwa mu nganda zihariye.
4. Sisitemu n'ibikoresho byo gushyira muri firigo: Iyi miyoboro ikoreshwa mu gutwara ibintu bikonjesha, cyane cyane aho bikenewe ibikoresho bidashobora gushyuha cyane.
Igipimo ngenderwaho cya ASTM A334
EN 10216-4: Itwikira imiyoboro y'icyuma idakozwe mu buryo bwa alloy n'iyakozwe mu buryo bwa alloy, ifite imiterere yihariye mu bushyuhe buri hasi.
JIS G 3460: ijyanye n'imiyoboro y'icyuma cy'umuringa ikoreshwa mu gutanga serivisi z'ubushyuhe.
GB/T 18984: ikoreshwa ku miyoboro y'icyuma idakora neza ku miyoboro y'umuvuduko ukabije. Igaragaza mu buryo burambuye imiterere n'ikorwa ry'imiyoboro y'icyuma ikwiriye ahantu hashyuha cyane.
Nubwo izi ngamba zishobora gutandukana mu buryo burambuye no mu bisabwa byihariye, zirasa mu ntego rusange no mu mikoreshereze yazo, ari byo kugenzura umutekano n'imikorere y'imiyoboro y'icyuma mu bidukikije bidafite aho bihuriye n'amazi.
Ibicuruzwa byacu bifitanye isano
Kuva yashingwa mu 2014, Botop Steel yabaye ikigo gikomeye mu kugurisha imiyoboro y'icyuma cya karuboni mu majyaruguru y'Ubushinwa, kizwiho gutanga serivisi nziza, ibicuruzwa byiza, n'ibisubizo byuzuye.
Iyi kompanyi itanga imiyoboro itandukanye y’icyuma cya karuboni n’ibindi bifitanye isano, birimo imiyoboro y’icyuma idakora neza, ERW, LSAW, na SSAW, ndetse n’urutonde rwuzuye rw’imiyoboro n’ibice bifunganye. Ibicuruzwa byayo byihariye birimo kandi alloys nziza n’ibyuma bitarangirika bya austenitic, byakozwe kugira ngo bihuze n’ibikenewe mu mishinga itandukanye y’imiyoboro.
Amatagi: ASTM A334, umuyoboro w'icyuma cya karuboni, astm a334 gr 6, astm a334 gr 1.
