Insimbi engagqwaliUhlobo lwensimbi, i-steel ibhekisa inani le-carbon (c) kule 2% elilandelayo libizwa ngensimbi, ngaphezu kwe-2% yinsimbi. Steel in the smelting process to add chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), titanium (Ti), molybdenum (Mo) and other alloying elements to improve the performance of steel so that steel has Ukumelana nokugqwala (okungukuthi, hhayi ukugqwala) ukuthi sivame ukusho insimbi engenacala.
Insimbi engagqwali kwinqubo yokunqwabanisa, ngenxa yokwengezwa kwezinto ezenziwayo zezinhlobonhlobo ezahlukahlukene, izinhlobo ezahlukene zenani elihlukile. Izici zalo zihlukile futhi, ukuze zihlukanise umqhele ngamanani ensimbi ahlukile.
Ukuhlukaniswa okujwayelekile kwensimbi engenasici
1. Insimbi engagqwali
Insimbi engagqwali inguhlobo oluvame kakhulu lwensimbi, njengensimbi esetshenziswa kabanzi, inokumelana kahle nokugqwala, ukumelana nokushisa, amandla okushisa aphansi kanye nezakhiwo zemishini; Ukunyathelanisa, ukugoba nenye ikhono lenqubo yokushisa kulungile, akukho ukwelashwa okushisa ngokushisa okunzima (akukho magceke, bese usebenzisa amazinga okushisa -196 ℃ ~ 800 ℃).
Ububanzi besicelo: Izindatshana Zasekhaya (1, 2 I-Tableware, amakhabethe, amapayipi angaphakathi, ama-heather amanzi, ama-boilers, amabhathi); Izingxenye ezizenzakalelayo (Windshield Wiper, muffler, imikhiqizo yokubumba); Izinto zokwelashwa, izinto zokwakha, amakhemikhali, imboni yokudla, ezolimo, izingxenye zomkhumbi
2. I-304l yensimbi engagqwali (l iyikhabhoni ephansi)
Njengensimbi ephansi ye-carbon 304, esifundazweni jikelele, ukumelana kwawo ukugqwala kanye no-304 nje okufanayo, kepha ngemuva kokushiswa kwe-welding noma ukuncishiswa kwengcindezi, ukumelana nokuqina kwengvimbo yokugqwala okuhle kakhulu; Esimweni sokungabikho ukwelashwa okushisa, kungagcina nokumelana okuhle kokugqwala, ukusetshenziswa kwamazinga okushisa -196 ℃ ~ 800 ℃.
Ububanzi besicelo: Kusetshenziswe kwizimboni zamakhemikhali, amalahle kanye nezidingo eziphakeme zokumelana nokugqwayiza kwezinkambi zemishini yangaphandle, izingxenye zokwakha ukushisa okulwa nokungapheliyo kanye nezingxenye zokwelashwa okushisa.
3. 316 Insimbi Engagqwali
316 insimbi engagqwali ngenxa yokwengezwa kwe-molybdenum, ngakho-ke ukumelana kwayo kokugqwala, ukumelana nokugqwala komoya kanye namandla aphezulu okushisa akulungile, kungasetshenziswa ngaphansi kwezimo ezinzima; Umsebenzi omuhle kakhulu wokuqina (ungezibuthe).
Scope of Isicelo: Imishini yamanzi olwandle, amakhemikhali, i-dyesuff, ekwenziweni kwamaphepha, i-oxalic acid, umanyolo kanye neminye imishini yokukhiqiza; Izithombe, imboni yokudla, izikhungo zasogwini, izintambo, izinduku ze-CD, ama-bolts, amantongomane.
4. 316l ama-stainless (l yi-carbon ephansi)
Njengoba uchungechunge oluphansi lwekhabhoni lwensimbi engu-316, ngaphezu kwezimpawu ezifanayo ngensimbi engama-316, ukumelana kwayo kokugqwala kwemingcele kuhamba kahle.
Ububanzi besicelo: Izidingo ezikhethekile ukumelana nemingcele yokugqwala okusanhlamvu.
Ukuqhathanisa ukusebenza
1. Ukwakheka kwamakhemikhali
Ama-stenless ama-316 futhi ama-316l angama-molybdenum aqukethe amansimbi angenasici. Okuqukethwe kwe-molybdenum kwensimbi engama-316l kuphakeme kancane kunaleyo yensimbi engama-316. Ngenxa ye-molybdenum ngensimbi, ukusebenza okuphelele kwensimbi kungcono kune-310 kanye nama-304 ama-steress angenasici. Ngaphansi kwezimo zokushisa eziphakeme, lapho ukugcwala kwe-sulfuric acid kungaphansi kwe-15% kanye nama-85%, ama-316 ama-stainless ahlukahlukene ahlukahlukene. Insimbi engu-316 futhi inezakhiwo ezinhle kakhulu ze-chloride zokuguguleka, ngakho-ke ivame ukusetshenziswa ezindaweni zasolwandle. Insimbi engu-316l engenasici inokuqukethwe okuphezulu kwekhabhoni engu-0.03. Ilungele izinhlelo zokusebenza lapho ukuvela khona kwe-wast-welde kungenzeki khona futhi lapho kudingeka khona ukumelana okuphezulu kokugqwala.
2. CoUkumelana ne-Rrosion
Ukumelana nokugqwala kwensimbi engagqwali engama-316 kungcono kunaleso sensimbi engama-304 engenasici. Inokumelana kahle kokugqwala kwinqubo yokukhiqiza ye-pulp nephepha. Futhi i-316 insimbi engagqwali nayo iyamelana nokuguguleka kwezimboni zasemanzini nasemncane. Ngokuvamile, i-304 insimbi engagqwali nensimbi engama-316 engenacala ekumelaneni nezinto zokugqwala kwamakhemikhali umehluko omncane, kepha kwabezindaba ezithile zihlukile.
Insimbi engagqwali yathuthukiswa ekuqaleni, eyayizwela ekugqwaneni okukhohlisayo kwezinye izimo. Ukungeza okwengeziwe okungu-2-3% molybdenum kunciphise lokhu kuzwela, okuholela ku-316. Ngaphezu kwalokho, la ma-molybdenum angeziwe anganciphisa ukugcwala kwamanye ama-acidi ashisayo ashisayo.
Insimbi engama-316 icishe ibe yinto ejwayelekile embonini yokudla kanye nophuzo. Ngenxa yokushoda komhlaba wonke we-molybderum kanye nokuqukethwe okuphezulu kwe-nickel ngensimbi engama-316 ngensimbi engenasici, i-316 insimbi engagqwali iyabiza kakhulu kunensimbi engama-304 engagqwali.
Ukugqwala okukhohlisayo kuyinto edalwe kakhulu ukugcwala okufakwe ebusweni bensimbi engenasici, okungenzeka ngenxa yokuntuleka komoya-mpilo futhi akukwazi ukwakha ungqimba oluvikelayo lwe-chromium oxide. Ikakhulu emavalovu amancane, kunethuba elincane lokufakwa kwi-disc, ngakho-ke ukupela kuyaqabukela.
Ezinhlotsheni ezahlukahlukene zamanzi aphakathi nendawo (amanzi aphuzekile, amanzi omfula, amanzi e-boiler, amanzi olwandle, njll. Phezulu kakhulu, ngalesi sikhathi 316 insimbi engagqwali kufanelekile. Ezimweni eziningi, ukumelana nokugqwala kwensimbi engama-304 engenasici kanye nensimbi engenacala engama-316 akufani kakhulu, kepha kwezinye izikhathi kungahluka kakhulu, kudingeka ukuthi uhlazizwe kakhulu, kudingeka uhlaziye ngokuhlupheka ngokwesisekelo.
3. Ukuvikelwa kokushisa
I-316 Insimbi Engagqwali inokumelana ne-oxidation enhle ekusetshenzisweni kwe-disetinious ngaphansi kwama-degree angama-1600 futhi ukusetshenziswa okuqhubekayo ngaphansi kwama-degree angu-1700. Ebangeni lama-degree angama-800-1575, kungcono ukungahambisani nensimbi eqhubekayo engama-316 insimbi engagqwali, kepha ngobubanzi bokushisa bokusebenzisa insimbi engagqwali, insimbi engagqwali, insimbi engenasici inokuphikiswa okuhle kokushisa. Insimbi engu-316l yensimbi engenacala inokuphikiswa okungcono ekuvumeni kwe-carbide kunensimbi engama-316 engenacala, engasetshenziswa kububanzi bokushisa obungenhla.
4. Ukwelashwa kokushisa
I-Annelung yenziwa ebangeni lokushisa le-1850 laya kuma-2050 degrees, lilandelwa yi-anveling esheshayo bese kupholisa ngokushesha. Insimbi engama-316 ayinakugcwala ukugcwala kanzima.
5. Ukushiswa kwe-welding
Insimbi engu-316 ingenacala inekhono elihle le-weld. Zonke izindlela ezijwayelekile ze-welding zingasetshenziselwa ukufudumala. Ngokusho kwenhloso ye-welding, i-316cb, i-316l noma i-309cc yensimbi engenacala yokupakisha noma i-electrode ingasetshenziselwa ukufudumala. Ukuze uthole ukumelana okuhle kakhulu kokugqwala, ingxenye ye-welding yensimbi engu-316 yensimbi engagqwali idinga ukunxuswa ngemuva kokufudumala. Isikhungo se-Post Welld asidingeki uma kusetshenziswa insimbi engagqwali engagqwali.
HikaloI-Tubing yensimbi engenasiciSebenzisa izinto ezibonakalayo ezingama-316l. Amanye ama-tube Fittings nama-valves avame ukusebenzisa izinto ezingama-316.
