ASTM A536 Nodular Cast Iron Bar | Inkoni y'icyuma ya Spheroidal Graphite
Intangiriro y'ibicuruzwa
ASTM A536 Nodular Cast Iron Bar ni ibikoresho byakozwe neza kandi byakozwe neza byagenewe gukoreshwa mu buryo bworoshye muri sisitemu za hydraulic na automotive. Byakozwe hakurikijwe amahame akomeye ya ASTM A536, iyi spheroidal graphite (SG) ihuza imbaraga z'icyuma n'ubushobozi bwo gushonga no kudahindagura ibyuma. By'umwihariko ihabwa agaciro kubera ubushobozi bwayo bwo kwihanganira umunaniro, ubushobozi bwo gukora, no kudahindagurika mu gihe cy'umuvuduko.
Ibyuma bikozwe mu cyuma gikozwe mu buryo bwa "nodular cast iron", kandi byitwa "ductile iron", bitandukanye n'iby'icyuma cy'umukara kuko ingano ya karuboni ikora uduce twa grafiti duto aho kuba uduce duto. Iri tandukaniro ry'imiterere yacyo rituma gikomera cyane kandi kigatanga imbaraga, bigatuma kiba ibikoresho byizewe byo kwikorera imizigo no guhangayika cyane.
- 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
Inkoni z'icyuma zikoreshwa mu buryo bwa "ductile iron rods" zikunze gukoreshwa mu bice nka za "veteri" n'ibice by'umugozi mu nganda zikora imashini, "crankshafts" n'ibice bihuza imodoka, imiyoboro n'ibice by'imiterere mu bwubatsi, ibice by'amazi mu mashini z'ubwubatsi, na "valve" n'ibice by'imashini zitanga ingufu.
