Ironmaking → Steelmaking → Nruam casting (los yog ingot casting) → Kub dov (tsim kub- cov khoom dov) → Txias dov (ua txias- cov khoom dov)
Nruam kub-dip galvanizing ntawm kub- dov steel strip yog txheej txheem tshiab hauv kub-dip galvanized ntawv ntau lawm. Cov txheej txheem no txhim kho qhov ua tau zoo ntawm steel sawb ntau lawm thiab tseem ceeb heev rau kev ua kom cov hlau sawb zoo. Keeb kwm hauv Nyij Pooj xyoo 1970, kub nruam-dip galvanizing ntawm kub-rolled steel sawb sawv cev rau kev tsim kho tshiab hauv steel strip ntau lawm technology. Nrog rau cov kev xav tau zoo zuj zus ntxiv rau cov ntawv kub -dip galvanized ntawv, ntxiv dag zog rau kev tshawb fawb mus rau qhov kub tsis tu ncua-dip galvanizing thev naus laus zis tau dhau los ua qhov kev xaiv yam tsis muaj kev xaiv rau cov tuam txhab steel.
Ntau xyoo dhau los, tsis tu ncua kub-dip galvanizing thev naus laus zis rau kub- dov steel sawb tau ua tiav qhov sib txawv ntawm txoj kev loj hlob, tab sis nws kuj muaj ntau yam teeb meem. Kev daws cov teeb meem no yog qhov tseem ceeb rau kev txhim kho cov txheej txheem thev naus laus zis ntawm kev kub ntxhov txuas ntxiv -dip galvanizing ntawm kub- dov steel strip. Hauv kev sib tw steel sawb kev lag luam, cov tuam txhab steel yuav tsum ntxiv dag zog rau kev tshawb fawb mus rau hauv kev kub ntxhov txuas ntxiv -dip galvanizing thev naus laus zis rau kub- dov steel sawb kom ua tiav ntev - txoj kev loj hlob thiab paub txog kev tsim kho tshiab hauv cov thev naus laus zis no.
