(1) thaum lub strip steel dov nyob rau hauv ib tug txias lub xeev, vim hais tias ntawm kev ua hauj lwm hardening ntawm lub sawb hlau, nws yuav tsum tau softened dua los ntawm intermediate annealing, thiab nws plasticity yuav tsum tau rov qab los nyob rau hauv thiaj li yuav mus txuas ntxiv dov;

(2) Ua ntej dov, cov nplais ntawm cov sawb hlau yuav tsum raug tshem tawm, yog li ua kom lub ntsej muag du ntawm cov hlua hlau thiab txo qhov hnav ntawm cov yob;

(3) Kev sib txhuam dov tau txais yuav, uas ua kom cov duab zoo ntawm cov hlua hlau, tswj cov thickness sib txawv ntawm cov hlua hlau, txo cov dov siab, thiab muaj txiaj ntsig zoo rau dov nyias cov khoom ntsuas.

(4) Cov txheej txheem txias thiab lubrication tau txais yuav, uas yog yooj yim los tswj qhov kub ntawm cov yob thiab sawb hlau, txo cov kev sib txhuam ntawm cov yob thiab sawb hlau thiab txo cov dov siab, uas muaj txiaj ntsig zoo rau kev tswj cov duab thiab tiv thaiv cov sawb. steel los ntawm lo rau yob.
