Qhov tuab ntau yam: 0.1mm-0.45mm

dav dav: 700mm-1000mm

Khoom siv: SPCC, SPCC, SPCD, SPCE, DC01, St12, DC03, St13, DC04, St14, Q235, St37-2G, S215G, JG300LA, JG340LA

Nta: Vim tias nws tsis tau annealed, nws qhov nyuaj yog siab heev (HRB ntau dua 90), thiab kev ua haujlwm tsis zoo heev. Tsuas yog ib qho txheej txheem khoov yooj yim ntawm tsawg dua 90 degrees (perpendicular rau qhov kev taw qhia winding) tuaj yeem ua tiav. Qee lub Hoobkas hlau tuaj yeem tsim cov txheej txheem plaub npaug.

Cov Lus Qhia Txog Khoom

Cov Cim Npe Khoom

Txheej txheem cej luam ntawm cov kauj vuam txias

Cov kauj dov txias yog ua los ntawm cov kauj dov kub. Hauv cov txheej txheem dov txias, cov kauj dov kub raug dov qis dua qhov kub recrystallization, thiab cov hlau dov feem ntau raug dov ntawm chav tsev kub. Cov ntawv hlau nrog cov ntsiab lus silicon siab muaj qhov tsis tshua muaj brittleness thiab plasticity qis, thiab yuav tsum tau preheated rau 200 ° C ua ntej dov txias. Txij li thaum cov kauj dov txias tsis tau cua sov thaum lub sijhawm tsim khoom, tsis muaj qhov tsis zoo xws li pitting thiab hlau oxide uas feem ntau pom hauv kev dov kub, thiab qhov zoo ntawm qhov chaw thiab qhov tiav zoo.

Cov Txheej Txheem Tsim Khoom Txias Rolled

Cov kauj vuam txias yog ua los ntawm cov kauj vuam kub, thiab nws cov txheej txheem ntau lawm feem ntau dhau los ntawm cov txheej txheem tseem ceeb xws li kev npaj cov khoom siv raw, dov txias, kho cua sov, theem thiab ua tiav.

Kev ua tau zoo ntawm cov khoom siv txias dov

Lub yob thiab lub ntsiav tshuaj yuav luag yog ib pob txiav. Lub kauj txias yog tau los ntawm pickling thiab txias dov lub kauj kub dov. Nws tuaj yeem hais tias nws yog ib hom kauj txias dov. Txias dov kauj (annealed xeev): Lub kauj kub dov yog tau los ntawm pickling, txias dov, hood annealing, leveling, (finishing).

Muaj 3 qhov sib txawv tseem ceeb ntawm lawv:

Nyob rau hauv tsos, lub dav dav chilled kauj yog me ntsis sloppy.

Cov ntawv dov txias xws li qhov zoo ntawm qhov chaw, cov qauv thiab qhov tseeb ntawm qhov ntev zoo dua li cov kauj txias.

Hais txog kev ua tau zoo, cov kauj txias uas tau txais ncaj qha tom qab cov txheej txheem dov txias ntawm cov kauj kub dov yog ua haujlwm tawv thaum lub sijhawm dov txias, ua rau muaj kev nce ntxiv ntawm lub zog tawm thiab ib feem ntawm kev ntxhov siab sab hauv tseem tshuav, thiab qhov tsos sab nraud yog "nyuaj". Nws hu ua kauj txias.

Yog li ntawd, lub zog tso zis: lub kauj txias loj dua li lub kauj txias-kuav (lub xeev annealed), yog li ntawd lub kauj txias-kuav (lub xeev annealed) zoo dua rau kev stamping. Feem ntau, qhov xwm txheej xa khoom tsis raug ntawm cov kauj txias dov yog annealed.
