SPCC Cold Rolled Steel Chev

Lus piav qhia luv luv:

Lub npe: Cold Rolled Steel Chev

Cold-rolled carbon steel (SPCC, SPCD, SPCE), qis carbon steel thiab ultra-low carbon steel (DC01 / St12, DC03 / St13, DC04 / St14), automotive stamping hlau (DC01-Q1, DC03-Q1, DC04 - Q1), txias-dov carbon steel strips (Q235, St37-2G, S215G), low-alloy high-strength txias-rolled steel strips (JG300LA, JG340LA), thiab lwm yam.

Thickness ntau: 0.1mm-0.45mm

Dav ntau yam: 700mm-1000mm

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

Nta: Vim nws tsis yog annealed, nws hardness siab heev (HRB yog ntau tshaj 90), thiab cov machining kev ua tau zoo heev.Tsuas yog cov txheej txheem kev taw qhia yooj yim ntawm qis dua 90 degrees (perpendicular rau winding direction) tuaj yeem ua tau.Qee cov hlau mills tuaj yeem tsim plaub zaug ua haujlwm.

Txheej txheem cej luam ntawm txias dov coil

Qhov txias dov kauj yog ua los ntawm kub dov kauj.Nyob rau hauv cov txheej txheem txias dov, kub dov coil yog dov hauv qab qhov kub ntawm recrystallization, thiab feem ntau dov hlau yog dov nyob rau hauv chav tsev kub.Cov ntawv hlau uas muaj cov ntsiab lus silicon siab muaj cov brittleness thiab tsis tshua muaj plasticity, thiab yuav tsum tau preheated rau 200 ° C ua ntej txias dov.Txij li thaum lub txias dov coil tsis yog cua sov thaum lub sij hawm tsim khoom, tsis muaj qhov tsis xws luag xws li pitting thiab hlau oxide uas feem ntau pom nyob rau hauv kub dov, thiab qhov zoo ntawm qhov chaw thiab qhov kawg yog zoo.

Txias Rolled Coil Production Process

Lub tshuab txias txias yog ua los ntawm cov kub dov, 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, txias dov, kho cua sov, qib thiab ua tiav.

Cold Rolled Coil Khoom ua haujlwm

Cov yob thiab cov ntsiav tshuaj yog yuav luag ib pob txiav.Lub chilled kauj yog tau los ntawm pickling thiab txias dov lub kub dov kauj.Nws tuaj yeem hais tias nws yog hom txias dov coil.Cold rolled coil (annealed state): Cov kub dov kauj yog tau los ntawm pickling, txias dov, hood annealing, leveling, (tiav).

Muaj 3 qhov sib txawv tseem ceeb ntawm lawv:

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

Cov ntawv txias txias xws li qhov zoo ntawm qhov chaw, cov qauv thiab qhov tseeb qhov tseeb yog qhov zoo dua li chilled coils.

Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, lub chilled coil tau ncaj qha tom qab txias dov txheej txheem ntawm cov kub dov kauj yog ua hauj lwm hardened thaum lub sij hawm txias dov, uas ua rau ib tug nce nyob rau hauv yield zog thiab ib feem ntawm cov kev ntxhov siab nyob rau hauv sab hauv, thiab sab nraud tsos yog "nyuaj" ".Nws yog hu ua chilled coil.

Yog li ntawd, lub zog yield: lub chilled kauj yog loj dua lub txias-kuav los tiag kauj (lub xeev annealed), yog li ntawd lub txias-kuav los tiag kauj (lub xeev annealed) zoo dua rau stamping.Feem ntau, lub neej ntawd xa khoom raws li txoj cai ntawm txias dov coils yog annealed.
