Kev tsim khoom thiab kev siv cov khoom siv stainless hlau yog ib txoj haujlwm ua ke nrog cov ntaub ntawv kev tshawb fawb, txheej txheem engineering, thiab ntawm - kev paub txog kev tswj hwm qhov chaw. Los ntawm kev xyaum ua haujlwm ntev -, kev lag luam tau maj mam sau cov txheej txheem kev ua tau zoo los daws cov teeb meem kev sib tw los ntawm cov khoom tshwj xeeb, kev ua haujlwm tseem ceeb, thiab kev cuam tshuam rau vuam rhiab heev ntawm cov hlau tsis muaj steel, kom ntseeg tau tias cov khoom ua tau raws li cov qauv xav tau hauv kev tiv thaiv corrosion, precision, thiab tsos. Qhov kev paub no tshwm sim tsis yog los ntawm kev kuaj cov ntaub ntawv pov thawj nkaus xwb tab sis kuj los ntawm kev ua kom zoo ntxiv thiab sau cov ntsiab lus ntawm cov kab ntau lawm.
Hais txog kev xaiv cov khoom siv thiab qib sib piv, kev ua tau zoo qhia txog qhov tseeb ntawm qhov chaw raws li qhov chaw pabcuam. Ntau hom stainless hlau sib txawv hauv cov txheej txheem tiv thaiv corrosion, cov khoom siv kho tshuab, thiab cov qauv nqi; theoretical parameters ib leeg tuaj yeem yooj yim saib xyuas qhov nyuaj ntawm kev ua haujlwm tiag tiag. Cov kws tshaj lij engineers yuav ua tib zoo xaiv austenitic, ferritic, lossis duplex stainless hlau los ntawm kev xav txog hom, concentration, kub, thiab kev ntxhov siab ntawm qhov nruab nrab, ntxiv los ntawm cov ntaub ntawv keeb kwm thiab tshuaj tsuag ntsev, kom tsis txhob ntxov ntxov vim xaiv cov khoom siv tsis raug. Piv txwv li, nyob rau hauv marine los yog tshuaj ib puag ncig nrog cov ntsiab lus chloride ion siab, 316L los yog duplex stainless hlau, uas muaj superior pitting corrosion kuj, yuav tsum tau nyiam tshaj tsuas yog cia siab rau qhov dav corrosion kuj ntawm 304.
Kev paub hauv kev tsim thiab machining tsom mus rau kev sib koom ua ke ntawm kev ua kom zoo dua qub thiab cov pwm. Stainless hlau muaj lub siab nyiam rau kev ua haujlwm txias txias, thiab stamping, ncab, thiab khoov yog nquag rau springback, cracking, thiab dimensional deviations. Cov kev paub dhau los qhia tau hais tias tsim nyog ua kom lub voj voog tuag fillet, me ntsis ua kom lub zog ntawm lub cev tsis muaj zog, siv ntau- dhau txoj kev loj hlob, los yog kev sib xyaw nruab nrab ntawm annealing tuaj yeem txo qhov kev ntxhov siab thiab cov txheej txheej tuab tuab heev. Hauv machining, siv cov nplua-grained cemented carbide lossis PVD- cov cuab yeej coated, nrog rau kev tswj cov nqi qis qis thiab txaus txias thiab lubrication, tuaj yeem txo cov cuab yeej adhesion thiab deg hardening, txuas lub neej ntawm cov cuab yeej, thiab tswj qhov seem stability.
Vuam thiab kev koom ua ke yog cov cheeb tsam uas muaj kev sib txuam ntau tshaj plaws. Stainless hlau welding yog yooj yim rau grain coarsening thiab intergranular corrosion nyob rau hauv tshav kub- cuam tshuam cheeb tsam. Cov kws tshaj lij yuav xaiv cov txheej txheem hluav taws xob qis (xws li pulsed TIG vuam lossis laser vuam) raws li cov phaj tuab thiab cov yam ntxwv ntawm cov qauv, thiab nruj me ntsis tswj qhov kub thiab txias thiab tiv thaiv cov roj purity. Tom qab-weld tov kev kho mob los yog pickling passivation tuaj yeem kho corrosion kuj. Kev paub kuj qhia tau hais tias kev sib txawv ntawm cov hlau tsis sib xws yuav tsum tau saib xyuas tshwj xeeb rau qhov sib txawv ntawm thermal expansion coefficients thiab carbon migration; Thaum tsim nyog, cov ntaub ntawv hloov pauv lossis cov txheej txheem hluav taws xob tsawg yuav tsum tau siv los txo qhov kev pheej hmoo ntawm kev sib koom ua ke.
Kev paub txog kev kho deg qhia txog kev tswj cov txheej txheem thiab kev ua tau zoo. Cov tshuab polishing yuav tsum tau maj mam los ntawm ntxhib mus rau qhov zoo kom tsis txhob loj ib zaug - theem txo uas tuaj yeem ua rau txiv kab ntxwv tev zoo nkauj. Electropolishing tsis tsuas yog txhim kho smoothness tab sis kuj tshem tawm me me tsis xws luag thiab txhim kho corrosion kuj. Xim thiab tiv thaiv- kev kho tus ntiv tes yuav tsum tau ua nyob rau hauv ib puag ncig huv si, nrog rau kev tswj cov yeeb yaj kiab tuab thiab kho kom zoo kom cov xim zoo ib yam thiab ruaj khov.
Tsis tas li ntawd, kev paub txog kev tswj xyuas zoo yog qhov tseem ceeb. Tsim cov ntsiab lus tshuaj xyuas ntawm cov txheej txheem tseem ceeb, ua ke nrog tsis yog- kev sim ua kom puas tsuaj, kev tshuaj ntsuam metallographic, thiab ntawm - qhov chaw kuaj xyuas kev sib dhos, tso cai rau kev tshawb pom raws sij hawm ntawm kev sib txawv thiab kev taug qab ntawm qhov laj thawj, tsim lub kaw - lub voj voog txhim kho. Kev sau thiab txheeb xyuas cov ntaub ntawv tsim khoom thiab kev tsis sib xws rau txhua pawg pab kom tsis txhob muaj teeb meem zoo sib xws hauv cov haujlwm tshiab.
Hauv cov ntsiab lus, kev ua tiav qib siab - cov khoom lag luam stainless hlau zoo yog nyob ntawm qhov ntev - cov kev paub dhau los hauv cov khoom xaiv, tsim, ua, vuam, kho qhov chaw, thiab kev tswj kom zoo. Cov kev pom zoo no tsis yog tsuas yog txhim kho kev ntseeg siab thiab kev ua neej ntawm cov khoom, tab sis kuj tseem muab kev txhawb nqa kev lag luam rau kev lag luam kom daws tau qhov nyuaj thiab puas tau - hloov cov kev xav tau ntawm daim ntawv thov.
