1.Yuav mus kuaj cov ntaub ntawv raw rau cov dov txias?
Cov khoom siv Raw: Xaiv cov qib tsim nyog ntawm kub {} {dov steel co- cov khoom lag luam (xws li tuab, lub zog, thiab cov khoom siv). Piv txwv li, qis - carbon kub-}}}} lub zog txias {}} rolled steel.
Kev tshuaj xyuas steel: phau ntawv kuaj xyuas yog ua los kuaj xyuas qhov loj me, kom tsis txhob muaj qhov sib txawv ntawm cov khoom txias (rau cov kab tawg) Kub - rolled billet thickness yog 2-6mm, thiab lub hom phiaj tuab tom qab dov txias yog 0.1-3 hli).
Steel Coil Butt Welding (Optional): If the length of a single coil is insufficient, multiple hot-rolled coils are welded end-to-end to form a continuous billet. Qhov no zam dhau ib txwm txias-}}}}} Tsis txhob nres rau coil hloov thiab txhim kho ntau lawm.
2.Qhov dab tsi yog cov kauj ruam tseem ceeb hauv kev xaiv?
Pickling: Tshem tawm teev los ntawm cov kauj.
Tom qab uncoiling, tus coil nkag mus rau hauv "nplai breaker" (lossis "ncab tsim thiab khoov cov kab mob ntxiv thiab txhim kho kev ua kom muaj txiaj ntsig.
Pickling tank kev kaw / Txau: Raws li cov tuab tuab, lub sijhawm siv hluav taws xob (feem ntau), feem ntau (10%)
Muab cov tshuaj yaug: Tom qab cov kua roj thiab ntsev rau cov roj hlau kom muaj txau nrog dej huv (lossis dej tsis muaj zog alkaline) los tiv thaiv cov xeb qis.
3.Txhua roj thiab dej noo?
Yog tias dov cov roj residue (seem ntawm cov roj txias txias thaum lub sijhawm kub (siv sodium}
Cov hlau phaj xim av, uas muaj cov dej noo tom qab yaug, yuav tsum tau qhuav siv cua sov huab cua) lossis siv tshuab kom tiv thaiv cov dej noo seem thiab xeb.
4.How is analing ua haujlwm?
Yog hais tias lub hardness ntawm kub - rolled steel chev yog ntau dhau (piv txwv li lub zog txias dua tom qab kub txias, qhia txog kev ua kom txias dua, coj mus ua kom txias heev. Hauv qhov no, "Annealing" yuav tsum ua ntej: kev siv zog ntawm HB ntawm HB 100), thiab txhim kho lub zog ntawm HB 100), thiab txhim kho cov yas rau hauv lub zog ntawm HB 100), thiab txhim kho cov yas rau hauv qab no kom yooj yim rau kom yooj yim dua dov.
5. Kuv txias dov tus txheej txheem tseem ceeb?
Yog hais tias lub hardness ntawm kub - rolled steel chev yog ntau dhau (piv txwv li lub zog txias dua tom qab kub txias, qhia txog kev ua kom txias dua, coj mus ua kom txias heev. Hauv qhov no, "Annealing" yuav tsum ua ntej: kev siv zog ntawm HB ntawm HB 100), thiab txhim kho lub zog ntawm HB 100), thiab txhim kho cov yas rau hauv lub zog ntawm HB 100), thiab txhim kho cov yas rau hauv qab no kom yooj yim rau kom yooj yim dua dov.
