siv cov hlab ntsha siab
(1) Cov ntsiab lus: Ntxiv nrog rau qhov yuav tsum tau muaj lub zog thiab tawv, nws kuj yuav tsum muaj cov khoom sib xws thiab nruj me ntsis txwv tsis pub muaj teeb meem.
(2) Hom: Raws li kev faib tawm muaj peev xwm muab faib ua carbon steel phaj, alloy steel phaj ob pawg; Raws li kev faib tawm lub zog tuaj yeem muab faib ua siab, nruab nrab, tsis tshua muaj siab steel phaj; Raws li kev siv ib puag ncig tuaj yeem muab faib ua siab, nruab nrab thiab qis kub steel phaj thiab corrosion resistant steel phaj.
(3) Cov chaw tsim khoom tseem ceeb thiab xa cov teb chaws tseem ceeb:
① Cov chaw tsim khoom tseem ceeb hauv tsev: Wugang, Angang, Laisteel, Shanghai Steel, Baotou Steel, Sansteel, thiab lwm yam;
② Lub teb chaws xa tawm loj thiab cheeb tsam: Nyiv, Russia, Lub teb chaws Yelemees, Eastern Europe thiab lwm lub teb chaws thiab cheeb tsam.
Cov hlab ntsha siab yog cov phaj hlau siv hauv kev tsim cov chav boilers, cov hlab ntsha siab thiab lwm yam kev tsim cov hlab ntsha. Vim tias cov phaj hlau no tau raug rau qee qhov cua siab thiab dej siab, nrog rau qhov sib txawv ntawm qhov kub thiab txias, xws li siab, nruab nrab, tsis tshua muaj kub, thiab lwm yam, qhov yuav tsum tau ua rau cov phaj steel no nruj dua.
