Kuyenga wothandizila ndi ufa woyera kapena granular organic zosungunulira, makamaka ndi zosiyanasiyana njira carbonate mogwirizana ndi gawo lina la okonzeka, chifukwa chachikulu nthunzi kuyenga wothandizila ngati ntchito kuchotsa zotayidwa madzi mkati hydrogen ndi mayfly mpweya makutidwe ndi okosijeni slag. Kodi ntchito ya woyenga wopanda utsi ndi chiyani?

　　Kugwiritsa ntchito zopanda utsi kuyenga wothandizila kungakhale zomveka kuwonjezera pa zotayidwa madzi wa hydrogen, mpweya makutidwe ndi okosijeni slag ndi inclusions ena, kusintha khalidwe castings, yosavuta kugwiritsa ntchito, kuwonjezera pa zotsatira zenizeni za mpweya kwambiri. Pambuyo kuyenga slag ndi ufa, zosavuta kusankha, pambuyo kuthetsa zotayidwa madzi peroxide kuchuluka ≤ 0.ml / 100 magalamu a Al, inclusions (A12O3) zikuchokera kuchepetsedwa ndi 20% pamwamba, castings inclusions kuipa yafupika ndi 50%, zotayidwa castings macroeconomic chiwerengero choyamba kalasi pinhole.

　　Utsi woyenga wothandizila pamwamba wosanjikiza limasonyeza yamkaka woyera, akhoza smelted mu aloyi mkuwa ndi kufa-ponyera zotayidwa kuchita njira kuyenga, akhoza zomveka kuchotsa sanali zitsulo inclusions zakuthupi, kuchotsa zitsulo zakuda zonyansa zina, kumapangitsanso khalidwe la castings.
