316l Ipayipi Lensimbi Engenamthungo
Ulwazi Oluyisisekelo
I-304 insimbi engagqwali iyinto evamile kunsimbi engagqwali, enobuningi obungu-7.93 g/cm³; kubizwa nangokuthi i-18/8 insimbi engagqwali embonini, okusho ukuthi iqukethe ngaphezu kwe-18% ye-chromium kanye ne-nickel engaphezu kuka-8%; ukumelana nokushisa okuphezulu kwe-800 ℃, ukusebenza kahle kokucubungula, Ukuqina okuphezulu, okusetshenziselwa kabanzi embonini nasembonini yokuhlobisa ifenisha kanye nokudla kanye nemboni yezokwelapha. Kodwa-ke, kufanele kuqashelwe ukuthi uma kuqhathaniswa nensimbi engagqwali engu-304 ejwayelekile, insimbi engagqwali yebanga lokudla engu-304 inenkomba yokuqukethwe eqinile. Isibonelo, incazelo yamazwe ngamazwe ye-304 steel stainless ngokuyisisekelo ingu-18% -20% chromium, 8% -10% nickel, kodwa insimbi engagqwali yezinga lokudla engu-304 iqukethe u-18% we-chromium no-8% we-nickel, okuvumela ukushintshashintsha phakathi kwebanga elithile, futhi Nciphisa okuqukethwe kwezinsimbi ezisindayo ezihlukahlukene. Ngamanye amazwi, insimbi engagqwali engu-304 ayiyona insimbi engagqwali engu-304.
Isibonisi somkhiqizo
Imininingwane Yomkhiqizo
Amapayipi ensimbi engenamthungo amapayipi ensimbi amelana nemidiya egqwalayo ebuthakathaka njengomoya, isitimu, namanzi, kanye nemidiya egqwala ngamakhemikhali njengama-asidi, ama-alkali, nosawoti. Eyaziwa nangokuthi ipayipi lensimbi elimelana ne-asidi.
Ukumelana nokugqwala kwamapayipi ensimbi engenamthungo kuncike ezintweni ze-alloying eziqukethwe ensimbi. I-Chromium iyingxenye eyisisekelo yokumelana nokugqwala kwensimbi engagqwali. Uma okuqukethwe kwe-chromium ensimbi kufinyelela cishe ku-12%, i-chromium ixhumana nomoya-mpilo endaweni egqwalayo ukuze yakhe ifilimu ye-oxide encane kakhulu (ifilimu yokuzibamba) ebusweni bensimbi. , Ingavimbela ukugqwala okwengeziwe kwe-matrix yensimbi. Ngokungeziwe ku-chromium, izakhi ze-alloying ezivame ukusetshenziswa zamapayipi ensimbi engenamthungo zihlanganisa i-nickel, i-molybdenum, i-titanium, i-niobium, ithusi, i-nitrogen, njll., ukuze kuhlangatshezwane nezidingo zokusetshenziswa okuhlukahlukene kwesakhiwo nokusebenza kwensimbi engagqwali.
Ipayipi lensimbi engenamthungo liyinsimbi eyindilinga ende engenalutho, esetshenziswa kabanzi ku-petroleum, amakhemikhali, ezokwelapha, ekudleni, embonini yokukhanya, izinsimbi zomshini kanye namanye amapayipi ezimboni kanye nezingxenye zesakhiwo semishini. Ngaphezu kwalokho, lapho amandla okugoba kanye ne-torsion afana, isisindo silula, ngakho-ke sisetshenziswa kabanzi ekwakhiweni kwezingxenye zemishini kanye nezakhiwo zobunjiniyela. Ibuye isetshenziselwe ukukhiqiza izikhali ezahlukahlukene ezijwayelekile, imiphongolo, amagobolondo, njll.
Inqubo Yokukhiqiza
Inezinyathelo ezilandelayo zokukhiqiza:
a. Ukulungiswa kwensimbi eyindilinga; b. Ukushisisa; c. Ukubhoboza okugoqiwe okushisayo; d. Sika ikhanda; e. Ukukha f. Ukugaya; g. Ukuthambisa; h. Cold rolling processing; i. Ukunciphisa amafutha; j. Ukwelashwa kokushisa kwesixazululo; k. Ukuqondisa; l. Sika ithubhu; m. Ukukha n. Ukuhlolwa komkhiqizo.
