Txias dov mills yog ib qho tseem ceeb ntawm kev lag luam steel, tshwj xeeb hauv kev tsim cov hlau zoo thiab cov raj. Cov mills no feem ntau siv cov hlau tsis muaj steel lossis carbon hlau ua cov khoom siv raw thiab dhau los ntawm cov txheej txheem ua haujlwm nyuaj kom ua tiav ntau yam sib txawv thiab ntau thiab tsawg ntawm cov hlau.
Lub tshuab txias dov pib nrog cov txheej txheem kub dov, qhov twg steel billets yog rhuab mus rau qhov kub thiab txias thiab ces dov rau hauv nyias los yog daim hlau. Cov rhuab billets no ces txias thiab xa mus rau lub txias dov zeb, uas muaj ib tug series ntawm yob thiab sawv.
Nyob rau hauv lub txias dov zeb, cov nplooj ntawv los yog daim hlau yog ntxiv txo nyob rau hauv thickness thiab dav los ntawm ib tug series ntawm yob. Cov yob no yog mounted rau ntawm qhov chaw sib cais thiab tig nyob rau hauv opposite lus qhia ntawm high speeds. Txhua qhov sawv ntsug muaj ntau lub yob, uas tig thiab txo qhov tuab thiab dav ntawm cov ntawv hlau lossis daim hlau.
Lub tshuab txias dov kuj tseem suav nrog cov qhov nruab nrab ntawm qhov nruab nrab, uas yog siv los ua kom cov hlau los yog cov ntawv txheeb tom qab txhua qhov dov dhau. Annealing tshem tawm cov kev ntxhov siab nyob hauv cov hlau thiab txhim kho nws cov khoom siv kho tshuab los ntawm kev rov kho cov qauv crystalline.
Tom qab qhov kawg dov thiab annealing, cov ntawv hlau los yog daim hlau raug xa mus rau lub tshuab leveling rau flattening thiab straightening. Lub tshuab no kho txhua qhov kev sib tw los yog curvature qhia thaum lub sij hawm dov txheej txheem thiab ua kom lub tiaj thiab ncaj nto tiav.
Thaum kawg, cov ntawv hlau lossis daim hlau raug xa mus rau kev kho saum npoo, xws li ntxuav, tiv thaiv xeb, thiab txheej txheej. Cov kauj ruam no ua tiav cov txheej txheem tsim khoom thiab xyuas kom meej tias cov khoom siv hlau ua tau raws li cov qauv tsim nyog.
Nyob rau hauv xaus, txias dov mills ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv hlau zoo rau ntau yam kev lag luam xws li kev tsim kho, tsheb, kav dej, thiab cov cuab yeej tsim khoom. Kev nkag siab txog cov khoom sib txawv thiab cov txheej txheem koom nrog hauv kev ua haujlwm txias dov zeb pab cov tuam txhab steel tswj lawv cov tshuab kom zoo, ua tiav cov khoom tsim tau siab tshaj plaws, thiab xa cov khoom lag luam nrog qhov tseeb.
