1022 Carbon Steel Hlau Qws Coils Sae1006 Sae1008 Hlau Qws Hlau Chev Rau Nail

Cov txheej txheem hlau rod ntau lawm feem ntau suav nrog cov kauj ruam hauv qab no:

Melting thiab refining: Cov txheej txheem tsim khoom pib nrog melting ntawm steel seem los yog lwm yam raw khoom nyob rau hauv ib tug hluav taws xob arc rauv (EAF) los yog yooj yim oxygen rauv (BOF).Thaum lub sij hawm no, impurities raug tshem tawm los ua kom cov hlau muaj pes tsawg leeg.

Nruam casting: Cov hlau molten yog ces cam khwb cia rau hauv cov khoom billets los ntawm ib tug nruam casting tshuab.Cov txheej txheem no yuav pab tsim kom muaj qhov nruam ntawm steel billets yam tsis muaj kev cuam tshuam.

Cua sov: Cov billets yog rhuab nyob rau hauv ib tug reheating rauv rau ib tug kub uas haum rau dov.Cov txheej txheem cua sov no pab txo cov quab yuam uas yuav tsum tau ua rau kev ua haujlwm dov tom ntej.

Rolling: Cov pob zeb preheated yog tom qab ntawd dhau los ntawm cov dov sawv ntsug, feem ntau hauv lub tshuab kub dov.Cov txheej txheem dov txo qhov billet qhov chaw hla ntu thiab nce nws qhov ntev, ua rau lub pas nrig hlau nrog qhov xav tau qhov ntev.Tus naj npawb ntawm dov sawv thiab qhov feem pua ​​​​ntawm qhov txo qis nws txawv nyob ntawm qhov kawg ntawm cov hlua hlau loj thiab cov khoom xav tau.

Txias: Tom qab dov, cov hlua hlau yog txias los ntawm huab cua txias lossis dej quenching kom ua tiav cov khoom xav tau thiab microstructure.

Kev kho deg: Raws li cov kev xav tau tshwj xeeb, tus pas nrig hlau yuav tau txais kev kho deg ntxiv xws li pickling lossis tua blasting kom tshem tawm cov nplai lossis impurities thiab txhim kho qhov chaw tiav.

Coiling: Cov pas hlau tiav lawm ces coiled rau hauv coils loj kom yooj yim tuav thiab thauj mus los.

Kev ntsuam xyuas thiab kev tswj kom zoo: Cov qauv yog muab los ntawm cov hlau rod coils los ua ntau yam kev ntsuam xyuas xws li lub zog tensile, tshuaj ntsuam xyuas, thiab ntsuas qhov ntev.Cov kev ntsuam xyuas no xyuas kom meej tias cov hlua hlau ua tau raws li cov qauv kev xav tau thiab cov kev qhia tshwj xeeb.

Ntim thiab xa khoom: Thaum cov hlau rod coils dhau qhov kev tswj xyuas zoo, lawv tau ntim rau hauv cov khoom ntim tsim nyog, sau npe, thiab npaj rau kev xa mus rau cov neeg siv khoom.

Zuag qhia tag nrho, xaim pas nrig ntau lawm yog txheej txheem nyuaj uas koom nrog ntau theem los hloov cov ntaub ntawv raw rau hauv cov khoom siv hlau hlau zoo tsim nyog rau ntau yam kev siv.
