Qhov saum npoo ntawm qhov chaw yog concave ntawm ib qho tob, ib sab yog convex, muaj cov kab ntawm lub suab, muaj cov ntu ntu, qee qhov txawv, thiab xim ntawm qhov tsis xws luag yog ci dua.
Thaum lub sij hawm tsim khoom, ntau yam kev pabcuam yob (nruj yob, pinch yob, pinch yob, straightening rolls, thiab lwm yam) yog daig nrog hlau filings, uas yog tshwm sim los ntawm av;
Cov ntaub ntawv hlau thiab cov khoom txawv teb chaws poob rau hauv cov phaj steel.
Cov khoom nyuaj txias dov steel kauj yog khawb los ntawm ib qho khoom tawv thaum lub sij hawm txias dov, feem ntau yog nyob rau hauv daim ntawv ntawm strips, thiab parallel mus rau dov kev taw qhia. Yog tias qhov degree hnyav, qhov zawj tuaj yeem hnov ntawm tes;
Cov khoom nyuaj txias dov steel coil yog khawb vim qhov suav nrog cov khoom tawv hauv cov ntaub plaub ntawm lub qhov cub annealing.
Muaj cov meteor zoo li cov khoom faib rau saum npoo ntawm cov khoom tawv txias dov steel kauj uas ntse, luv thiab tob hauv cov hlau sawb. Kev faib tawm yog tsis sib xws thiab ntxhib, nrog protrusions.
