I-EN-GJS 400-15 / 500-7 Amabha Ensimbi Ahlanganisiwe | Insimbi Ye-Graphite Eyisiphepho
Isingeniso Somkhiqizo
I-EN-GJS 400-15 / 500-7 Ama-Ductile Iron Bars ayimikhiqizo yensimbi ephothiwe esebenza kahle kakhulu eyenziwe ngokuhambisana nezindinganiso zaseYurophu, eyenzelwe ngqo izinhlelo zokusebenza ezidinga amandla aphezulu, ukuguquguquka okuhle, kanye nokusebenza kahle kakhulu. Lezi zingodo zikhiqizwa ngesakhiwo esincane se-graphite esinobukhulu obuhlukahlukene, esinikeza izakhiwo eziphawulekayo zokudonseka kanye nokumelana nokushayisana, okwenza kube ukukhetha okuguquguqukayo kwezinhlelo zokusebenza zesakhiwo nezemishini.
Uchungechunge lwe-EN-GJS luyaziswa kakhulu eYurophu ngokunikeza uhla lwezinhlanganisela zamandla nobude. I-EN-GJS 400-15 ibonakala ngokuqina nokuqina okuhle kakhulu, kanti i-EN-GJS 500-7 inikeza amandla aphezulu ngenkathi igcina ukuguquguquka okwanele. Lezi zingodo zensimbi ezithambile zifanele izingxenye ezibhekana nokucindezeleka okuphindaphindiwe, ukudlidliza, noma umthelela ophakathi. Ukusebenza kwazo kahle kuzenza zilungele kokubili imisebenzi yokugoqa kanye nokuqeda ngokunemba.
- imigoqo yensimbi ethambile ikhiqizwa ngokuhambisana nezindinganiso zomhlaba wonke. Amazinga ensimbi asetshenziswa kakhulu emigoqo yensimbi ethambile abonakaliswa ngezindlela ezahlukene ngokusho kwamazwe ahlukene kanye nezindinganiso.
Okulandelayo yizinhlobo ze-ductile iron steel grades (amamaki) ezisetshenziswa kakhulu ngaphansi kwezinhlelo eziningana ezijwayelekile ezivamile:
| I-ASTM A536 | NGO-1563 | I-ISO 1083 | I-JIS G5502 |
| 60-40-18 | I-EN-GJS-400-15 | I-GGG40 | FCD400 |
| 65-45-12 | I-EN-GJS-450-10 | - | FCD450 |
| 80-55-06 | I-EN-GJS-500-7 | I-GGG50 | FCD500 |
| 100-70-03 | I-EN-GJS-600-3 | I-GGG60 | FCD600 |
Incazelo Yomkhiqizo
Ibha yensimbi ethambile iyinto ethuthukisa izakhiwo zayo zomshini ngokufaka ama-spheroidizing agents njenge-magnesium noma i-cerium ukuze kufakwe insimbi ukuze kwakhiwe i-graphite ibe yisakhiwo esiyindilinga. Ngokuphathelene nokwakheka kwamakhemikhali, izingxenye eziyinhloko zensimbi ethambile yi-iron, i-carbon, i-silicon, kanye ne-manganese, i-phosphorus, i-sulfur nezinye izinto. Ukwengezwa kwama-spheroidizing agents njenge-magnesium noma i-cerium kubalulekile, okukhuthaza ukwakheka kwesakhiwo esiyindilinga ku-graphite.

Izinhlelo Zokusebenza Zomkhiqizo
Imigoqo yensimbi ethambile ye-EN-GJS isetshenziswa ezimbonini eziningi ezahlukene, okuhlanganisa:
>Izingxenye zemishini ezifana namagiya, ama-pulley, kanye nama-shaft
>Izingxenye zesakhiwo emishinini yezimboni
>Imizimba yamavalvu kanye nezinhlobo ze-hydraulic
>Amabhuleki ezimoto kanye nezindlu zokuhlukanisa
>Ihadiwe yokuphakamisa nokubopha
>Izingxenye zemishini yezolimo
