Ibha Eyindilinga Yensimbi Engagqwali Ngekhwalithi Enhle
Isingeniso Somkhiqizo
Insimbi (Fe): iyingxenye yensimbi eyisisekelo yensimbi engagqwali;
I-Chromium (Cr): iyisici esiyinhloko esenza i-ferrite, i-chromium ehlanganiswe nomoya-mpilo ingakhiqiza ifilimu ye-Cr2O3 engagqwali, ingenye yezinto eziyisisekelo zensimbi engagqwali ukuze kugcinwe ukumelana nokugqwala, okuqukethwe kwe-chromium kukhulisa ikhono lokulungisa ifilimu lensimbi, insimbi evamile engagqwali yokuqukethwe kwe-chromium kufanele ibe ngaphezu kwe-12% yokuqukethwe kwe-chromium;
I-Carbon (C): iyisici esiqinile sokwakheka kwe-austenite, ingathuthukisa kakhulu amandla ensimbi, ngaphezu kwekhabhoni ekumelaneni nokugqwala nayo inomthelela omubi;
I-Nickel (Ni): iyisici esiyinhloko esenza i-austenite, inganciphisa ukugqwala kwensimbi nokukhula kwezinhlamvu ngesikhathi sokushisa;
I-Niobium, i-titanium (Nb, Ti): iyingxenye eqinile yokwakha i-carbide, ingathuthukisa ukumelana kwensimbi nokugqwala kwe-intergranular. Kodwa-ke, i-titanium carbide inomthelela omubi kukhwalithi engaphezulu yensimbi engagqwali, ngakho insimbi engagqwali enezidingo eziphezulu ngokuvamile ithuthukiswa ngokungeza i-niobium ukuze kuthuthukiswe ukusebenza.
I-nitrogen (N): iyisici esiqinile esakha i-austenite, ingathuthukisa kakhulu amandla ensimbi. Kodwa ukuqhekeka okuguga kwensimbi engagqwali kunomthelela omkhulu, ngakho insimbi engagqwali ngezinjongo zokugxiviza ukuze ilawule ngokuqinile okuqukethwe kwe-nitrogen.
I-Phosphorus, isulfure (P, S): iyisici esiyingozi ensimbi engagqwali, ukumelana nokugqwala nokugxivizwa kwensimbi engagqwali kungaba nomthelela omubi.
Isibonisi somkhiqizo
Impahla Nokusebenza
| Okubalulekile | Izici |
| 310S insimbi engagqwali | I-310S insimbi engagqwali iyinsimbi engagqwali ye-austenitic chromium-nickel enokumelana okuhle ne-oxidation, ukumelana nokugqwala, ngenxa yamaphesenti aphezulu e-chromium ne-nickel, i-310S inamandla angcono kakhulu okukhasa, ingaqhubeka nokusebenza emazingeni okushisa aphezulu, ngokumelana okuhle kokushisa okuphezulu. |
| Ibha eyindilinga yensimbi engagqwali engu-316L | 1) Ukubukeka okuhle okucwebezelayo nokuhle kwemikhiqizo egoqiwe ebandayo. 2) ukumelana nokugqwala okuhle kakhulu, ikakhulukazi ukumelana ne-pitting, ngenxa yokwengezwa kwe-Mo 3) amandla aphezulu okushisa aphezulu; 4) umsebenzi omuhle kakhulu wokuqina (izakhiwo ezibuthakathaka kazibuthe ngemuva kokucubungula) 5) okungewona uzibuthe esimweni sesixazululo esiqinile. |
| 316 insimbi engagqwali eyindilinga | Izici: Insimbi engagqwali engu-316 iyinsimbi yesibili esetshenziswa kakhulu ngemva kwe-304, ikakhulukazi esetshenziswa embonini yokudla kanye nemishini yokuhlinza, ngenxa yokwengezwa kwe-Mo, ngakho ukumelana nokugqwala kwayo, ukumelana nokugqwala komkhathi namandla okushisa aphezulu kuhle kakhulu, kungasetshenziswa ezimweni ezinzima; umsebenzi omuhle kakhulu wokuqina (okungewona uzibuthe). |
| 321 insimbi engagqwali eyindilinga | Izici: Ukwengezwa kwezakhi ze-Ti kunsimbi engu-304 ukuvimbela ukugqwala komngcele wokusanhlamvu, kulungele ukusetshenziswa emazingeni okushisa angama-430 ℃ - 900 ℃. Ngaphandle kokwengezwa kwezakhi ze-titanium ukunciphisa ubungozi bokugqwala kwempahla ye-weld nezinye izinto ezifana ne-304 |
| 304L insimbi engagqwali eyindilinga | 304L insimbi engagqwali eyindilinga iwuhlobo lwensimbi engagqwali engu-304 enokuqukethwe kwekhabhoni ephansi futhi isetshenziswa ezinhlelweni lapho kudingeka khona ukushisela. Okuqukethwe kwekhabhoni ephansi kunciphisa imvula ye-carbide endaweni ethintekile ekushiseni eduze nendawo yokushisela, okungaholela ekugqwaleni kwe-intergranular (ukuguguleka kwe-weld) yensimbi engagqwali ezindaweni ezithile. |
| 304 insimbi engagqwali eyindilinga | Izici: Insimbi engagqwali engu-304 ingenye yensimbi engagqwali ye-chromium-nickel esetshenziswa kakhulu, enokumelana nokugqwala okuhle, ukumelana nokushisa, amandla okushisa aphansi kanye nezakhiwo zemishini. Ukumelana nokugqwala emkhathini, uma umkhathi wezimboni noma izindawo ezingcoliswa kakhulu, kudinga ukuhlanzwa kusenesikhathi ukugwema ukugqwala. |
Ukusetshenziswa Okuvamile
Insimbi engagqwali eyindilinga inethemba elibanzi lesicelo futhi isetshenziswa kabanzi ku-hardware ne-kitchenware, ukwakha umkhumbi, i-petrochemical, imishini, imithi, ukudla, amandla kagesi, amandla, i-aerospace, njll, ukwakhiwa nokuhlobisa. Imishini yokusetshenziswa emanzini olwandle, amakhemikhali, udayi, iphepha, i-oxalic acid, umanyolo nezinye izinto zokukhiqiza; izithombe, imboni yokudla, izindawo ezisogwini, izintambo, izinduku zama-CD, amabhawodi, amantongomane
Imikhiqizo Eyinhloko
Imigoqo eyindingilizi yensimbi engagqwali ingahlukaniswa ibe yigodi elishisayo, eligoqiwe futhi elibandayo elidonswa ngokuya ngenqubo yokukhiqiza. Insimbi engagqwali egoqelwe eshisayo eyindilinga imininingwane ye-5.5-250 mm. Phakathi kwazo: 5.5-25 mm wensimbi engagqwali encane eyindilinga ehlinzekwa kakhulu ngezinqwaba zemigoqo eqondile, evame ukusetshenziswa njengemigoqo yensimbi, amabhawodi kanye nezingxenye ezihlukahlukene zemishini; insimbi engagqwali eyindilinga engaphezu kuka-25 mm, esetshenziswa kakhulu ekwenzeni izingxenye zemishini noma amabhilidi ensimbi angenamthungo.
