Hlau dov, lub siab- txheej txheem tsim uas hloov cov duab ntawm steel ingots thiab billets ntawm rotating rollers, aims los tsim cov ntaub ntawv uas xav tau, xws li daim hlau, strips, hlau rods, thiab ntau lwm yam hlau. Nws tseem siv zog los txhim kho qhov zoo ntawm cov hlau. Cov khoom lag luam xws li cov ntawv tsheb hlau, choj hlau, boiler steel, pipeline steel, rebar, rebar, hluav taws xob silicon steel, galvanized ntawv, tinplate, thiab txawm lub tsheb ciav hlau log tag nrho undergo cov txheej txheem ntawm steel dov.
Cov txheej txheem steel dov tuaj yeem muab faib ua kub dov thiab txias dov raws li qhov kub thiab txias sib txawv thaum dov. Raws li qhov txheeb ze ntawm qhov chaw ua haujlwm thiab cov chais thaum lub sijhawm dov, lawv tuaj yeem muab faib ua qhov ntev dov, hla kev dov, thiab hla - dov. Tsis tas li ntawd, steel dov tuaj yeem muab faib ua cov pa dov thiab tshwj xeeb dov raws li qhov tshwj xeeb tsim cov yam ntxwv ntawm cov khoom dov. Cycling dov, spinning, thiab dabtsi yog khoov tsim tag nrho cov poob nyob rau hauv qeb ntawm tshwj xeeb dov.
Hauv kev tsim khoom tiag tiag, vim muaj ntau yam thiab sib txawv ntawm cov khoom siv dov, ntau qhov kev sib tw dov feem ntau yuav tsum tau txais cov khoom kawg. Yog li ntawd, steel dov ntau lawm feem ntau muab faib ua ob theem: semi-cov khoom tiav thiab cov khoom tiav tiav. Tsis tu ncua cam khwb cia hlau slabs tshwm sim los ntawm steel zeb yog thawj rhuab nyob rau hauv ib tug cua sov rauv, ces rov dov nyob rau hauv ib tug tawg zeb, thiab thaum kawg nkag mus rau ib tug xov zeb rau xov. Cov txheej txheem no zoo ib yam li "dov noodles" hauv kev tsim hlau: los ntawm kev rov ua dua thiab thawb, cov hlau maj mam nce mus txog qhov xav tau tuab thiab loj.
Nyob rau hauv lub kub dov kab, tom qab tau rhuab thiab softened, lub slab yog pub los ntawm rollers rau hauv lub dov zeb rau dov, ua rau cov hlau ntawm qhov xav tau loj. Tag nrho cov txheej txheem dov yog tas mus li thiab ua haujlwm tau zoo, nrog rau cov hlua hlau txav nrawm nrawm nrog cov chais thiab qib siab ntawm automation.
Ua ntej commissioning, steel dov cov cuab yeej yuav tsum tau ua ib tug series ntawm cua sov thiab tawg cov kauj ruam kom ntseeg tau tias du nkag mus rau hauv lub kub dov kab rau dov. Piv rau cov txheej txheem steelmaking ib txwm, siv cov nrum nrum slabs rau steel dov yog qhov yooj yim dua. Feem ntau, lub thickness ntawm nruam nruam slabs yog tswj ntawm 150 thiab 250 hli. Tom qab dephosphorization, lawv pib dov thawj zaug thiab muab pub los ntawm cov yob rau hauv lub tshuab dov rau dov. Lub tshuab dov feem ntau muaj ob peb plaub- lub siab dov mills, txhua qhov nruab nrog kev ceev- ntsuas yob thiab ya davhlau rau txiav lub taub hau ntawm ntu.
Txawm li cas los xij, cov txheej txheem steel dov kuj tseem muaj ntau yam kev phom sij, xws li siab - cov cuab yeej siv cua sov thiab cov cuab yeej siv siab - ceev, uas tuaj yeem ua rau muaj xwm txheej xws li kev raug mob thiab kev puas tsuaj rau lub cev. Tsis tas li ntawd, cov nplaim hluav taws kub hnyiab, tawg, thiab cov pa phem xws li roj thiab oxygen, nrog rau cov khoom siv hluav taws xob thiab hydraulic, ua rau muaj kev pheej hmoo ntawm kev nyab xeeb. Yog li ntawd, kev ua raws li cov cai tswj kev nyab xeeb thiab cov txheej txheem yog qhov tseem ceeb thaum lub sijhawm ua haujlwm steel dov kom ntseeg tau tias muaj kev nyab xeeb ntawm cov neeg siv khoom.
