I-Womic Steel – Izixazululo Zepayipi Lensimbi Engagqwali Ezisebenza Kakhulu Ezingu-347H

1. Ukubuka Konke Okubalulekile

Ipayipi lensimbi engagqwali elingu-347H liyinsimbi engagqwali ye-austenitic ene-carbon ephezulu ezinzile eyaziwa ngamandla ayo aphezulu okushisa okuphezulu, ukushibilika okuhle kakhulu, kanye nokumelana okuvelele nokugqwala kwe-intergranular. Ukwengezwa kwe-niobium (Nb) kuthuthukisa amandla okuhamba futhi kuvimbela ukuna kwe-chromium carbide emingceleni yokusanhlamvu, okuqinisekisa ukumelana okuthuthukisiwe kokuzwela.

2.Ukwakheka Kwamakhemikhali (Okuvamile)

3. Izakhiwo Zomshini Nokugqwala

Izakhiwo Zemishini (ASTM A213):

5. Inqubo Yokukhiqiza

1. Izinto Zokusetshenziswa: Ama-billet ensimbi aqinisekisiwe avela ezigayweni zasekhaya nezamazwe ngamazwe

2. Ukugoqa Okushisayo: Ama-billet ashiswa ku-1150–1200°C, abhobozwe futhi agoqwe ukuze kusetshenziswe amapayipi amakhulu noma odonga olujiyile

3. Umdwebo Obandayo: Umdwebo obandayo odlula izikhathi eziningi ukuze uthole usayizi onembile kanye nokuphela kobuso

4. Ukwelashwa Kokushisa: Ukufakwa kwesisombululo ku-980–1150°C, ukucima amanzi ngokushesha ukuze kuncishiswe imvula ye-carbide

5. Ukushisela: Izinqubo ze-GTAW (TIG), PAW, kanye ne-SAW, kusetshenziswa ucingo lokugcwalisa lwe-ER347 ukuze kuqiniswe; izinketho zokuhlanza ingemuva ziyatholakala

6. Ukuqeda Okungaphezulu: Ukukhahlela, ukudlulisa (HNO₃/HF), kanye nokupholisha ngomshini (Ra ≤ 0.2µm uma ucela)

7. Ukuhlolwa: 100% RT (ukuhlolwa kwe-radiographic) kwama-welds; ukuhlolwa kwe-ultrasonic, i-hydrostatic, i-PMI, kanye nokugqwala kwe-intergranular njengoba kudingeka

6. Isitifiketi Nokulawulwa Kwekhwalithi

Amapayipi ensimbi engagqwali angu-347H e-Womic Steel aqinisekiswe ngaphansi kwalokhu:

- Ukuhlolwa kokugqwala (IGC nge-ASTM A262)

- Ukuhlolwa okungabhubhisi (i-UT, i-RT, i-Eddy current)

- Ukuhlolwa kobukhulu kanye nokulandelela okugcwele

7. Izinkambu Zokufaka Isicelo

Ipayipi lensimbi engagqwali elingu-347H lisetshenziswa kabanzi ku:

- Ukukhiqizwa Kwamandla: Ama-Superheater, ama-reheater, amapayipi amakhulu omusi ezitshalweni zamandla ezishisayo ezingabalulekile kakhulu nezibaluleke kakhulu

- Amandla Okushisa Elanga: Amathangi okugcina ukushisa kasawoti oncibilikisiwe (450–565°C), okufakazelwe ukusetshenziswa kumaphrojekthi kulo lonke elaseShayina (Yumen, Haixi)
