cov khoom siv thev naus laus zis
Galvanized steel kauj qib qhia
Cov qib galvanized steel kauj yog SGCC, DX51D, SPCC thiab lwm yam. Ntawm lawv, SGCC sawv cev rau cov khoom siv txias-kuav los tiag carbon steel phaj, DX51D stands rau kub-dip galvanized steel phaj, thiab SPCC stands rau cov txias-dov carbon steel phaj. Cov qib sib txawv ntawm cov hlau coils no sawv cev qhov sib txawv ntawm cov khoom siv, kev ua tau zoo, txheej txheem thiab lwm yam.
Ntau qhov kev thov ntawm cov qib sib txawv
SGCC galvanized steel kauj yog tsim rau kev tsim kho, khoom siv hauv tsev, tsheb, rooj tog thiab lwm yam, tshwj xeeb tshaj yog rau kev tsim cov tub yees, tshuab ntxhua khaub ncaws thiab lwm yam khoom siv hauv tsev. DX51D galvanized steel kauj muaj siab hardness, uas yog tsim rau cov khoom siv ruaj khov thiab muaj zog. SPCC galvanized steel kauj muaj kev ua haujlwm zoo heev thiab tsim nyog rau boilers, rooj tog thiab lwm yam.
DX51D galvanized steel kauj txheej txheem ntau lawm
Uncoiling thiab welding
Uncoiling steel kauj, muab cov hlau sawb uas yuav tsum tau ua haujlwm tas mus li, vuam tus Tsov tus tw ntawm cov hlua rau pem hauv ntej thiab cov hlau lead ntawm lub nraub qaum kom ntseeg tau tias cov khoom siv tas mus li.
Degreasing ntxuav
Kev tu vaj tse yog los ntxuav lub ntsej muag ntawm cov sawb hlau, tshem tawm cov roj dov thiab cov hmoov hlau, kom tau txais cov txheej txheem adhesion zoo thiab qhov chaw zoo, feem ntau suav nrog tshuaj tsuag, txhuam hniav, electrolytic tu, txhuam hniav, tshuaj tsuag, extrusion qhuav thiab cua kub kom qhuav. khoom siv.
anneal
Recrystallization annealing yog nqa tawm ntawm dov tawv sawb kom tau txais cov khoom siv zoo, thiab cov txheej txheem zoo tau txais los ntawm kev tswj cov cua sov cua.
Cua riam zinc txheej tswj
Cov txheej tuab ntawm cov sawb saum npoo yog tswj los ntawm kev txhaj tshuaj, feem ntau yog huab cua lossis cov nitrogen ntshiab, rau hauv cov kab nrib pleb tom qab zinc boiler.
