235 steel hlau
Lus piav qhia luv luv:
Cov sawb hlau feem ntau yog muab rau hauv cov coils, uas muaj qhov zoo ntawm qhov siab qhov tseeb, qhov zoo ntawm qhov zoo, ua haujlwm yooj yim, cov khoom txuag thiab lwm yam.Ib yam li cov hlau phaj, cov sawb hlau tau muab faib ua cov sawb zoo tib yam thiab cov hlau zoo zoo raws li cov khoom siv;Raws li cov txheej txheem ua, nws tau muab faib ua cov kab kub dov thiab txias-dov strip.
Cov txheej txheem ntau lawm ntawm cov khaub thuas dov strip feem ntau yog raws li nram no: pickling → dov → txheej txheem lubrication → annealing → leveling → shearing → ntim.
Cov txheej txheem txias txias: Pickling - dov - annealing - synchronous lubrication ntawm dov loj - antirust roj - qib thiab sizing - polishing - ntim
Kub strip dov txheej txheem: cua sov rauv - dephosphorization tshuab - roughing zeb - dephosphorization tshuab - xov zeb - nto zoo soj ntsuam ntsuas - txheej txias - coiler - baler - npav tshuab - dov Tshuag slab
Kub dov sawb txheej txheem ntau lawm: ua ntej, nce qhov kub ntawm lub cua sov rau qhov yuav tsum tau dov kub, ces nkag mus rau lub roughing dephosphorization tshuab los ntawm cov menyuam lub rooj los kho cov hlau oxide scale generated los ntawm cov slab, ces nkag mus rau hauv lub roughing dov tsev rau yob. qhov dav thiab tuab ntawm cov sawb, thiab tom qab ntawd thauj nws los ntawm lub rooj rau cov menyuam mus rau lub tshuab ua kom tiav dephosphorization los kho cov hlau oxide nplai tsim rau ntawm qhov chaw ntawm cov sawb, nkag mus rau qhov kawg dov chav tsev kom paub meej dov ntawm thickness thiab dav. lub strip steel.Tom qab qhov kub thiab txias ntawm cov sawb hlau yog nruj me ntsis tswj los ntawm cov rooj sib tham los ntawm txheej txias ua ntej coiling, nws nkag mus rau hauv lub coiler los ua steel kauj.Thaum kawg, nws yog bundled, sprayed thiab xa mus rau lub coil warehouse rau cia thiab ntim.
