Ukukhethwa Kwebanga – Isevisi Yezinga Lokushisa Eliphansi
| Ibanga | Izinga Lokusebenza | Izinga Lokuhlolwa Komthelela | Uhlobo Lwezinto | Ukunwebeka (MPa) | Ukukhiqiza (MPa) |
|---|---|---|---|---|---|
| I-Grade 1 | -45°C (-50°F) | -45°C | Insimbi yekhabhoni | ≥380 | ≥205 |
| I-Grade 6 | -45°C (-50°F) | -45°C | Insimbi yekhabhoni | ≥415 | ≥240 |
💡 Ibanga 6 liyathandwa ezinhlelweni eziningi – inikeza amandla aphezulu (≥415 MPa tensile) uma iqhathaniswa ne-Grade 1 (≥380 MPa) ezingeni elifanayo lokusebenza.
Ukuhlanganiswa Kwamakhemikhali
| Ibanga | I-C max | Mn | P max | S max | Si |
|---|---|---|---|---|---|
| I-Grade 1 | 0.30 | 0.40-1.06 | 0.025 | 0.025 | — |
| Ibanga 6 | 0.30 | 0.29-1.06 | 0.025 | 0.025 | ≥0.10 |
📌 Inothi leBanga 1: Ukwehla ngakunye kwe-carbon ngo-0.01% ngaphansi kuka-0.30% kuvumela ukwenyuka kwe-manganese ngo-0.05% ngaphezu kuka-1.06%, kufike emkhawulweni ongu-1.35%.
Izici Zemishini
| Izinga | Amandla Okudonsa (MPa) | Amandla Okuvumela (MPa) | Ukunwetshwa (%) |
|---|---|---|---|
| I-Grade 1 | ≥380 | ≥205 | ≥35 |
| Ibanga 6 | ≥415 | ≥240 | ≥30 |
Izidingo Zomthelela We-Charpy Ekushiseni Okuphansi
| Ibanga | Izinga Lokuhlola (°C) | Amandla Amaphakathi (J) | I-Min Individual (J) |
|---|---|---|---|
| I-Grade 1 | -45 | 18 | 14 |
| Ibanga 6 | -45 | 18 | 14 |
💡 Ukuhlolwa kwe-Charpy impact kuyimpoqo kukho kokubili Ibanga 1 neBanga 6 ku- -45°C – umbiko oqinisekisiwe uhambisana nayo yonke imithwalo.
Inqubo Yokukhiqiza – Ukudonsa Okubandayo Nokuqina Ekushiseni Okuphansi
Inqubo Yokudonsa Ebandayo Yesevisi Yezinga Lokushisa Eliphansi:
-
Amashubhu agingqiwe ashisayo ziyacutshungulwa ukuze kususwe amakhasi
-
Ukudonsa okubandayo inciphisa ngokuqondile ububanzi
-
Ukwelashwa ngokushisa (ukujwayela noma ukukhulula ingcindezi) – kuqinisekisa ukwakheka kwezinhlayiya ezinhle ukuze kube nokuqina ekushiseni okuphansi
-
Ukuqondisa – iqinisekisa ukungaguquguquki kobukhulu
-
Ukusika ngokunemba – ukuze kube ubude obunembile
-
Ukuhlolwa kwe-NDT nokuhlolwa kwe-hydrostatic okungu-100% – liqinisekisa ubuqotho
-
Ukuhlolwa kwe-Charpy impact ku- -45°C – iqinisekisa ukuqina ekushiseni okuphansi
Ukuqhathanisa Izinga – Izinga 1 nezinga 6
| Isici | I-Grade 1 | I-Grade 6 |
|---|---|---|
| Amandla Okuqina | ≥380 MPa | ≥415 MPa (phezulu) |
| Amandla Okuvumela | ≥205 MPa | ≥240 MPa (phezulu) |
| Inani le-Manganese | 0.40-1.06% | 0.29-1.06% |
| Ukutholakala kwe-Silicon | Akucacisiwe | ≥0.10% |
| Ukusetshenziswa Okujwayelekile | Ukushisa okuphansi okuvamile | Edundule kakhulu – amandla aphezulu |
💡 Ibanga 6 linikeza amandla okudonsa aphakeme ngo-17% kune-Grade 1 – ikhethwa kakhulu ezinhlelweni eziningi zamazinga okushisa aphansi lapho amandla aphezulu ewusizo.
Izicelo Eziyinhloko – Inkonzo Yamazinga Aphansi Okushisa
| Imboni | Ukusetshenziswa | I-Grade Enconyiwe | Izinga Lokushisa Lenkonzo |
|---|---|---|---|
| I-Petrochemical | Izishintshi zokushisa eziphansi | Ibanga 6 | -45°C |
