Chitsulo chosapanga dzimbiri 347 1.4550
Deta iyi imagwira ntchito pazitsulo zosapanga dzimbiri 347 / 1.4550 zotentha komanso zozizira zopindidwa, mizere ndi mipiringidzo, zinthu zomalizidwa, ndodo ndi magawo komanso machubu achitsulo opanda msoko ndi owotcherera pazolinga zamakina ndi zomangamanga.
Kugwiritsa ntchito
Pazigawo zomangira zomwe ziyenera kugonjetsedwa ndi kutentha kwa pafupifupi 1050 ° C ndi kutenthedwa kwambiri ndi mpweya wa sulfurous, makamaka pamwamba pa 900 ° C, ndizochepa kwambiri.
