Zombi zifite imbaraga nkeya zo gutanga umusaruro zigera kuri 275MPa (ubugari bw'urukuta ≤16mm). Itandukaniro rikomeye riri mu miterere y'ingaruka: S275J0H ifite ingufu nkeya zo gutanga umusaruro zigera kuri 27 J kuri 0°C, mu gihe S275J2H ifite ingufu nkeya zo gutanga umusaruro zigera kuri 27 J kuri -20°C.
Ikwiriye gukoreshwa mu nyubako no mu nyubako z’ubuhanga ziremereye cyane.
BS EN 10219 ni Standard EN 10219 yemewe n'Ubwongereza mu Burayi.
Ubugari bw'urukuta ≤40mm, Umurambararo wo hanze ≤2500mm.
CFCHS ni incamake y'igice cy'umwobo gikozwe mu buryo bukonje.
Amahame ngenderwaho ya EN 10219 akubiyemo imiterere myinshi y’ibyuma bifite ubugari, harimo uruziga, kare, urukiramende, n’urudodo, kugira ngo bihuze n’ibisabwa bitandukanye mu ikoreshwa.
Botop Steelyihariye mu gutanga imiyoboro y'icyuma ifite impande zizunguruka ifite ubunini butandukanye n'imikorere itandukanye kugira ngo ihuze n'ibikorwa bitandukanye by'inganda, igenzura ko ibyo abakiriya bacu bakeneye byihariye bishobora kugerwaho.
Kuva yashingwa mu 2014,Botop Steelyabaye 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'ibyuma bya karuboni n'ibindi bifitanye isano, harimoSMLS, ERW, LSAW, naSSAWUmuyoboro w'icyuma, ndetse n'urutonde rwuzuye rw'ibikoresho by'imiyoboro n'ibice by'imiyoboro. Ibikoresho byayo byihariye birimo kandi aloyi nziza n'ibyuma bitagira umugese bya austenitic, byakozwe kugira ngo bihuze n'ibikenewe mu mishinga itandukanye y'imiyoboro.
Twiteguye gushinga umubano w'ubufatanye namwe no gushyiraho ahazaza heza hamwe.
Ibyuma bidakozwe mu buryo bw'umwimerere byo gukora ibice bikonje bifite ubukonje birakurwamo ogisijeni kandi bigomba kuba byujuje ibisabwa kugira ngo bigerweho.
Ibisabwa by'ingenzi kuri S275J0H na S275J2H ni ibi bikurikira:FF(Ibyuma byishwe neza birimo azote bifatanya mu buryo buhagije kugira ngo bifatanye azote ihari (urugero: nibura 0.020 % y'Al yose cyangwa 0.015 % ya Al ishongeshwa)).
Uko ibintu bitangwa: Ibyuma bizingiye cyangwa bisanzwe/bisanzwe bizingiye (N) kuri JR, J0, J2, na K2.
Imiyoboro y'icyuma ikoreshwa muri EN 10219 ishobora gukorwa na byombiERW(gusudira ubudahangarwa bw'amashanyarazi) naSAWinzira zo gukora (gusudira arc munsi y'amazi).
Umusaruro waImiyoboro ya ERWifite akarusho ko kwihuta no guhendutse cyane kandi ikunze gutorwa mu mishinga isaba umusaruro munini kandi ihendutse.
ERWimiyoboro ikoreshwa mu gukora uburebure buto n'ubugari bw'inkuta buto, mu giheSAWImiyoboro ikwiriye cyane uburebure bunini n'inkuta nini. Hitamo ubwoko bw'umuyoboro w'icyuma bukwiye umushinga wawe.
Imiyoboro ya ERW ikorwa hakurikijwe EN 10219 ubusanzwe ntabwo isaba gukata imbere mu byuma.
Ibi biterwa nuko imiyoboro ya EN 10219 ikoreshwa cyane cyane mu miterere y’inyubako, nko mu bwubatsi no mu buhanga bwa mekanike, aho ibisabwa kugira ngo habeho isura yo gusudira akenshi biba bitagoye cyane nko ku miyoboro y’umuvuduko cyangwa imiyoboro ifite umuvuduko mwinshi. Kubwibyo, igihe cyose imbaraga n’ubuziranenge bw’umuvuduko byujuje ibisabwa n’ibipimo ngenderwaho, imiyoboro y’imbere ishobora gukoreshwa nta gukataho by’inyongera.
Nta gikorwa cyo gutunganya ubushyuhe gikurikiraho, keretse ko gusudira bishobora kuba biri mu buryo bwo gusudira cyangwa bushyushye.
Isesengura ry'Ibikoresho (Ibikoresho by'Indabyo Bikozwe mu Bitabirwa)
S275J0H na S275J2H byombi bifite agaciro ntarengwa karubone ingana na (CEV) ka 0.40%.
S725J0H na S275J2H zifite CEV ntarengwa ya 0.4% bigaragaza ubushobozi bwo gusudira neza kandi nta ngaruka zo gukomera no kwangirika mu gihe cyo gusudira.
Ishobora kandi kubarwa hakoreshejwe formula ikurikira:
CEV = C + Mn / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15.
Isesengura ry'ibicuruzwa (Imiterere ya chimique y'ibicuruzwa byarangiye)
Mu gihe cy’ikorwa ry’icyuma, imiterere ya shimi ishobora guhinduka bitewe n’impamvu nyinshi, kandi izi mpinduka zishobora kugira ingaruka ku miterere n’ubwiza bw’icyuma.
Imiterere ya shimi y'umuyoboro w'icyuma irangiye igomba kubahiriza imiterere ya shimi y'umuyoboro n'impinduka zawo zemewe.
Ibipimo by'imiterere ya mekanike birimo imbaraga z'umusaruro, imbaraga zo gukurura, kurekura, n'imbaraga z'ingaruka.
Guhagarika stress ku bushyuhe burenze 580°C cyangwa mu gihe kirenga isaha imwe bishobora gutuma imikorere ya mashini igabanuka.
Inyandiko:
Gupima ingaruka ntibikenewe iyo ubugari bwagenwe buri <6mm.
Imiterere y'ingaruka z'imiyoboro y'ubuziranenge ya JR na J0 ntiyemezwa keretse iyo byavuzwe.

Uburebure bw'ubworoherane
Imiyoboro y'ibice by'ubururu ikozwe hakurikijwe EN 10219 irashobora gusudira.
Mu gusudira, gucika kw'ubukonje mu gace ko gusudira ni byo bishobora gutera ingorane kuko ubunini, imbaraga, na CEV by'ibicuruzwa byiyongera. Gucika kw'ubukonje biterwa n'ibintu byinshi:
urugero rwinshi rwa hydrogen ishobora gukwirakwira mu cyuma gisudira;
imiterere y’umubiri igoramye mu gace kagizweho ingaruka n’ubushyuhe;
uburemere bunini bw'umuvuduko mu ngingo ishongeshejwe.
Ubuso bw'umuyoboro w'icyuma bugomba kuba bworoshye kandi budafite inenge zagira ingaruka ku mikorere y'umusaruro, nko kwangirika, imyobo, gushwanyagurika, cyangwa ingese.
Uduce duto, imiyoboro, cyangwa imiyoboro miremire idakomeye yakozwe n'inganda biremewe igihe cyose ubugari bw'urukuta busigaye bushobora kwihanganira, inenge ishobora gukurwaho hakoreshejwe gusya, kandi ubugari bw'urukuta rwasanwe bwujuje ibisabwa byibuze.
Botop SteelNtabwo itanga gusa imiyoboro y'icyuma myiza hakurikijwe EN 10219, ahubwo inatanga amahitamo menshi yo gusiga hejuru imiyoboro y'icyuma kugira ngo ihuze n'ibyo abakiriya bayo bakeneye mu mishinga itandukanye y'ubuhanga. Iyi miyoboro igenewe kongera ubudahangarwa bw'imiyoboro no kongera uburinzi, bityo ikarushaho kumara igihe kirekire.
