Umhlinzeki Weplate Yensimbi Engagqwali Esebenza Kakhulu - QN1803 (304D) Ipuleti lensimbi engagqwali - Huaxin

1.  Incazelo:

Ibanga lomkhiqizo omusha i-QN1803 liwumkhiqizo wokuqala we-nitrogen ephezulu emhlabeni, ukumelana nokugqwala okuphezulu, umkhiqizo wensimbi engagqwali we-nickel osindisa i-austenitic.

Ngokwesisekelo sokuqinisekisa ukumelana nokugqwala okulingana nensimbi engagqwali engama-304, amandla ezinto ezibonakalayo ayathuthukiswa, kanye nezinto ezibonakalayo.

izindleko ziyancipha, okwenza kube engabizi kakhulu futhi kube nokuncintisana kakhulu emakethe kune-304 insimbi engagqwali.

Izici zokwakheka komkhiqizo omusha: i-nitrogen ephezulu (≥2000ppm), i-chromium ephezulu (≥18%), i-nickel emaphakathi (~3.0%) kanye nekhopha ephezulu (≥1.5%).

Ngepulatifomu yedijithali ye-R&D yedijithali ye-Thermo-Calc isoftware yokubala yesigaba se-thermodynamic kanye nokuhlaziya idatha yokuhlola, ukulungisa

Izakhi ze-alloying zengxenye ngayinye yesigaba azithuthukisi kuphela ukumelana nokugqwala komkhiqizo, kodwa futhi zenza amandla okukhiqiza we-QN1803

izikhathi ezingaphezu kwe-1.3 kune-304.

I-QN1803 inezici ezilandelayo:

1) i-pitting corrosion okulingana ne-PREN=Cr+3.3Mo+30N-Mn ingaphezulu kuka-19.0, okungenani enokumelana nokugqwala okufanayo okungu-304

insimbi engagqwali.

2) ukumelana nokugqwala okufanayo ku-dilute hydrochloric acid, hlanza i-sulfuric acid, i-acetic acid + usawoti nezinye izindawo kungcono kakhulu

304 insimbi engagqwali.

3) ukumelana nokugqwala kungcono kuno-304 esimweni sokusetshenziswa sangempela ngemuva kokugoba, ukugxiviza, isimo esiqinile nokunye ukwakheka okubandayo.

4) amandla okukhiqiza angaphezu kuka-1.3 izikhathi ezingaphezu kuka-304 zensimbi engagqwali, futhi inobude obungekho ngaphansi kuka-45%. Gqoka ukumelana futhi

ukusebenza kokukhathala kungcono kune-304 insimbi engagqwali.

5) ukusebenza kahle kokushisela, amandla emva kokushisela aphakeme kunalawo ensimbi engagqwali engama-304, futhi ukumelana nokugqwala

uma kuqhathaniswa naleyo yensimbi engagqwali engu-304.

2. Ukuqhathanisa nezinto ezingama-304:

3. Ukuqhathaniswa kwezakhiwo:

4. Umbukiso wekhoyili ne-palte:

5. Ukulethwa ngeloli:

6. Ukulayishwa Kwesitsha:

7.Uhlelo lokusebenza:

➢Imboni yezokwakha: ukwakha uphahla, izindonga, ama-purlin, izingxenye zesakhiwo ezithwala umthwalo, njll.:

➢Izicabha zehardware namafasitela: njengamadrayini aphansi, amahinji, amahinji, ama-slide rails, njll.;

➢Amapayipi ashiselwe okuhlobisa: anjengocingo, imigoqo yeziteshi, izitebhisi ezizihambelayo, amafasitela okuvikela, njll.;

➢Amapayipi ashiselwe ezimbonini: njengamapayipi egesi, amapayipi endle ezimbonini;

➢Iziqukathi zamathangi embonini: njengeziqukathi zokuthutha amanzi, imibhoshongo yokususa igesi;

➢ Impahla yokuzalanisa: njengomkhombe wokudlisa izingulube, umkhombe wokukhuluphalisa kabili;

➢ Izinsiza zikamasipala: njengamadokodo amabhasi, izindawo zokukhucululwa kwendle.
