Cov hlau dub annealed spcc txias dov pib nws txoj kev taug kev ntawm lub chaw tsim khoom ntawm lub chaw tsim khoom Cold Rolled Steel Coil uas muaj koob npe nrov. Cov txheej txheem pib nrog cov khoom siv raw (feem ntau yog cov hlau dov txias lossis cov ntawv), uas tau kuaj xyuas kom zoo. Cov ntawv hlau no dhau los ntawm ntau cov txheej txheem los txhim kho lawv lub zog thiab kev ruaj khov.
Ua ntej, cov hlau uas dov txias hauv kauj raug ntxuav kom tshem tawm cov khoom tsis huv, roj lossis cov khoom seem uas yuav cuam tshuam cov txheej txheem tom ntej. Qhov no ua kom muaj qhov chaw huv si, lav qhov nplaum zoo tshaj plaws. Tom ntej no, cov hlau phaj raug muab tso rau hauv cov kua qaub, feem ntau hu ua lub dab dej pickling, kom tshem tawm cov xeb lossis nplai. Cov txheej txheem no, hu ua pickling, ntxiv ib txheej kev tiv thaiv rau qhov chaw hlau thaum tseem muab cov qauv sib npaug.
Tom qab pickling thiab rinsing, cov laug cam dhau los ntawm ib qho txheej txheem hu ua blackening. Cov txheej txheem no yog ua tiav los ntawm kev siv ib txheej hloov pauv rau ntawm qhov chaw ntawm cov hlau, ua rau muaj qhov chaw dub tob. dub annealed txias dov hlau kauj 0.5 hli muaj qhov zoo nkauj thiab yog qhov nrhiav tau ntau hauv kev lag luam xws li tsheb, rooj tog thiab kev tsim kho.
Qhov zoo ntawmdub annealed txias dov hlau coilsmus dhau nws qhov kev zoo nkauj. Cov kauj no muaj kev tiv thaiv corrosion zoo heev thiab tsim nyog rau kev siv sab nraum zoov. Tsis tas li ntawd, lawv muab cov xim zoo heev thiab weldability, muab cov chaw tsim khoom nrog kev ywj pheej tsim qauv ntau dua.
