Thaum cov kauv steel yeeb nkab raug tsim, cov npoo tsis raug tshwm sim, thiab qhov cuam tshuam muaj ntau yam. Hauv kev xyaum ntau lawm, cov yeeb nkab steel feem ntau txo qis los ntawm qhov qhuav thiab tsis ncaj ncees lawm sab. Yog li tsim nyog.
1. Kev khoov khoov ntawm txoj siv hlau yog qhov tseem ceeb uas ua rau sab tsis ncaj ncees ntawm cov yeeb nkab steel. Nyob rau hauv kev tsim cov kauv steel yeeb nkab, qhov khoov khoov ntawm txoj siv hlau yuav txuas ntxiv mus rau hauv lub kaum sab xis, uas yuav ua rau lub vuam sib txawv hloov, uas yuav ua rau qhib seams, tsis ncaj ncees lawm npoo thiab txawm teeb tsa. Sab. Nws cuam tshuam rau qhov zoo ntawm cov yeeb nkab steel.
2. Cov ntug tsis zoo ntawm txoj siv hlau yog lwm qhov laj thawj tseem ceeb ntawm ntug tsis ncaj ncees lawm.
3. Vim qhov tsis zoo ntawm cov duab thiab qhov loj thiab qhov tseeb ntawm tus Tsov tus tw ntawm cov hlua hlau, nws yog ib qho yooj yim uas yuav ua rau cov hlua hlau ua rau nyuaj khoov thiab ua rau tsis ncaj ncees lawm ntug.
4. Thaum tus Tsov tus tw ntawm cov hlua hlau loj, yog tias nws tsis ua haujlwm zoo thaum nws nyob hauv qab, nws yuav yooj yim ua rau lub ntug tsis ncaj ncees lawm.
