EN-GJS 400-15 / 500-7 Uduti tw'icyuma dukozwe mu buryo bwa Ductile | Icuma cya Graphite cya Spheroidal
Intangiriro y'ibicuruzwa
EN-GJS 400-15 / 500-7 Ductile Iron Bars ni ibikoresho by'icyuma gikozwe mu buryo buhanitse kandi bukozwe mu buryo bukurikije amahame y'i Burayi, by'umwihariko byagenewe gukoreshwa bisaba imbaraga nyinshi, ubushobozi bwo gukora neza, no gukoresha neza ibyuma. Ibi bikoresho bikorwa mu buryo bwa graphite ya spheroidal, itanga imiterere itangaje yo gukurura no kudakora neza, bigatuma biba amahitamo menshi yo gukoreshwa mu buryo bw'imiterere n'ikoranabuhanga.
Uruhererekane rwa EN-GJS rurakunzwe cyane mu Burayi kubera ko rutanga imbaraga n'uburebure butandukanye. EN-GJS 400-15 irangwa no gukomera no gukomera cyane, mu gihe EN-GJS 500-7 itanga imbaraga nyinshi mu gihe ikomeza koroha bihagije. Utu duti tw'icyuma dukoresha amashanyarazi tubereye ibice bihora bihura n'ubukana, gutigita, cyangwa gukubitwa mu rugero ruciriritse. Kuba ibyuma bikoreshwa mu ikoranabuhanga bituma biba byiza haba mu bikorwa byo gukaraba no kurangiza neza.
- Uduti tw'icyuma dukozwe hakurikijwe amahame mpuzamahanga. Ingano z'icyuma gikoreshwa cyane mu duti tw'icyuma dukozwe mu buryo butandukanye hakurikijwe ibihugu n'amahame atandukanye.
Ibi bikurikira ni ibipimo by'icyuma gikoreshwa mu byuma bikozwe mu buryo bwa ductile (amanota) muri sisitemu nyinshi zisanzwe:
| ASTM A536 | MU 1563 | ISO 1083 | JIS G5502 |
| 60-40-18 | EN-GJS-400-15 | GGG40 | FCD400 |
| 65-45-12 | EN-GJS-450-10 | - | FCD450 |
| 80-55-06 | EN-GJS-500-7 | GGG50 | FCD500 |
| 100-70-03 | EN-GJS-600-3 | GGG60 | FCD600 |
Ibisobanuro by'igicuruzwa
Uduce tw’icyuma duto ni ibikoresho binoza imiterere yabyo binyuze mu kongeramo ibintu bihindura imiterere nka manyeziyumu cyangwa cerium kugira ngo icyuma gikore graphite mu buryo bw’uruziga. Ku bijyanye n’imiterere ya shimi, ibice by’ingenzi bya feri ihindura imiterere ni icyuma, karuboni, silicon, hamwe na manganese, fosifore, sulfur n’ibindi bintu. Kongeramo ibintu bihindura imiterere nka manyeziyumu cyangwa cerium ni ingenzi, bitera imbere kurema imiterere y’uruziga muri graphite.

| Uburyo bwo kuvura ubushyuhe | byakuweho, byahinduwe bisanzwe, cyangwa byazimishijwe kandi bigakonjeshwa |
| Imiterere y'ubuso | Nkuko byakozwe mu buryo bwa "As-cast" / "Fined machines /" "Pulled" |
| Kurekura | 2% – 18% |
| Uko ibyo bigezwaho bihagaze | Urubaho rw'uruziga/urubaho rw'impande/urubaho rw'igorofa cyangwa ukata uko ubyifuza |
Porogaramu z'ibicuruzwa
Uduti tw’icyuma duto twa EN-GJS dukoreshwa mu nganda zitandukanye, harimo:
>Ibice bya mekanike nk'ibikoresho by'amashanyarazi, ibyuma bifunga imipira, n'imigozi
>Ibice by'imiterere mu mashini z'inganda
>Imiyoboro ya valve n'ibikoresho bya hydraulic
>Udukingirizo tw'imodoka n'aho imodoka zihurira
>Ibikoresho byo guterura no gukurura
>Ibice by'imashini z'ubuhinzi
