1. Khoom piav qhia
Aluminium clad steel daim hlau los ntawm txias dovyog cov khoom sib xyaw ua los ntawm txhuas thiab hlau nrog lub cev sib txawv, tshuaj lom neeg thiab cov khoom siv hluav taws xob ntawm qhov sib cuam tshuam los ntawm kev siv tshuab sib xyaw. Nws tuaj yeem txhim kho kev ua tau zoo ntawm cov khoom siv hlau ib leeg, thiab tau siv rau hauv cov chaw tsim hluav taws xob, cov khoom siv hauv tsev thiab lwm yam kev lag luam hauv xyoo tas los no. Cov txheej txheem tseem ceeb ntawm txhuas hlau sib xyaw phaj muaj xws li tawg vuam, kub dip aluminium plating thiab dov composite. Nyob rau hauv daim ntawv no, aluminium steel composite phaj yog npaj los ntawm txias dov composite nyob rau hauv chav tsev kub, uas muaj cov khoom zoo nto zoo, siab qhov tseeb, ib puag ncig tiv thaiv nyob rau hauv cov txheej txheem ntau lawm, uniform kev ua tau zoo, zoo sib xws, txawm thickness ratio ntawm txhuas txheej rau hlau. txheej, thiab yooj yim mus cuag loj ntau lawm.
2. Khoom nta
Tom qab txias dov, laminating thiab annealing ntawm 52{18}} degree rau 24 teev, lub zog thiab plasticity ntawm 4A6{22}}/08Al composite phaj txo, tus nqi cupping nce los ntawm 7.68 hli mus rau 10.75 hli, lub elongation nce ntawm 1 feem pua rau 42.5 feem pua, lub zog tensile txo los ntawm 705 MPa rau 315 MPa, lub zog tawm los ntawm 500 MPa rau 260 MPa, thiab lub hardness txo los ntawm 213.3 HV0.5 mus rau 93.5 HV0.5. 2) Tom qab annealing kev kho mob, aluminium steel composite daim hlau yog metallurgically bonded ntawm lub interface. Tom qab annealed ntawm 520 degree rau 24 teev, ua tiav recrystallization tshwm sim, thiab tsis muaj hlau txhuas binary brittle theem yog tsim nyob rau hauv lub aluminium steel interface. Yog li ntawd, nws tau txiav txim siab tias 520 degree rau 24 teev yog qhov zoo tshaj plaws annealing txheej txheem nyob rau hauv no dov system.
3. Daim ntawv thov ntawm clad phaj
Raws li cov khoom siv kho kom zoo nkauj, hlau yog ruaj khov, ci ntsa iab thiab yuav tsum tau saib xyuas me ntsis, yog li nws tuaj yeem txo qis heev.
Piv txwv li, cov phab ntsa ntawm txoj kev hauv World Trade Center hauv New York, Tebchaws Asmeskas, yog ua los ntawm cov khoom siv hlau loj; Aluminium yog lub teeb, nws nto tuaj yeem oxidized thiab xim, thiab nws yooj yim rau kev ua. Kev sib xyaw ob cov hlau no rau hauv cov khoom siv tshiab tsis tsuas yog txo cov nqi kho kom zoo nkauj, txo cov txheej txheem kho kom zoo nkauj, tab sis kuj muaj kev nyab xeeb dua thiab tsim nyog.
4. FAQ
Cov txheej txheem ntawm "txias dov compound plus temper rolling plus annealing" yog saws rau lub compound dov ntawm Aluminium clad steel daim hlau los ntawm txias dov. Cov kev hloov ntawm microstructure tau pom los ntawm kev siv lub tshuab ntsuas qhov muag thiab lub tshuab ntsuas hluav taws xob, thiab cov khoom siv hluav taws xob ntawm cov phaj sib xyaw tau txiav txim siab los ntawm microhardness, tensile test thiab cupping test. Cov txiaj ntsig tau pom tias lub microstructure ntawm 08Al steel txheej tom qab dov thiab laminating yog fibrous tis raws li dov kev taw qhia. Tom qab annealing ntawm 520 degree rau 24 teev, 08Al steel txheej tau ua tiav recrystallization, tsis muaj Fe2Al5 binary brittle theem yog tsim nyob rau hauv lub interface ntawm txhuas thiab hlau, lub zog ntawm composite phaj txo, lub plasticity nce, hardness txo, thiab cov neeg kho tshuab zog. ncav cuag
Raws li kev ua haujlwm yuav tsum tau ua, cov txheej txheem annealing zoo tshaj plaws rau cov phaj sib xyaw hauv qab lub tshuab dov tau txiav txim siab yog 520 degree rau 24h.
