Gwiritsani ntchito ng’anjo yosungunuka motetezeka ndikuwonetsetsa zizolowezi zabwino za 7!

(1) Kawirikawiri onani momwe zinthu zosungunulira m’ng’anjo. Mlanduwo uyenera kuwonjezedwa munthawi yomwe mlanduwo usungunuke kwathunthu. Zimapezeka kuti katawala akuyenera kuthandizidwa munthawi yake kuti asatenthe m’ng’anjo chifukwa chakukwera kwachitsulo chosungunuka chachitsulo, chomwe chimaposa malo osungunuka (mchenga wa quartz 1704 ℃). Kuti

(2) Chitsulo chosungunuka chikasungunuka, slag iyenera kuchotsedwa ndipo kutentha kuyesedwe munthawi yake, ndipo chitsulo chosungunuka chiyenera kutulutsidwa munthawi yomwe chikafikire m’ng’anjo yotentha. Kuti

(3) Nthawi zonse, pamene khoma lopanda mtanda ndi 1/3 yam’mbali yamoto woyaka, ng’anjo iyenera kuthyoledwa ndikumangidwanso. Kuti

(4) Chitsulo chosungunuka chiyenera kutayidwa kamodzi pamlungu kuti kuyeze kukula kwa ng’anjo ndikutenga mawonekedwe ake, kumvetsetsa mkhalidwe wa ng’anjoyo munthawi yake, ndikuthana ndi mavuto aliwonse pakapita nthawi. Kuti

(5) The recarburizer imawonjezedwa pang’ono ndi pang’ono pokonza chitsulo. Kuwonjezera molawirira kwambiri kumamatira pansi pa ng’anjo ndipo sikungasungunuke mosavuta mu chitsulo chosungunuka. Kuonjezera mochedwa kudzawonjezera nthawi yosungunuka ndi kutentha, zomwe sizimangobweretsa kuchedwetsa kusintha kwa kapangidwe kake, komanso zimayambitsanso kutentha kwambiri. Kuphatikiza kwa ferrosilicon (onjezerani Si), kwa malo osungunulira osungunuka omwe ali ndi mphamvu zosafooka, chifukwa kuchuluka kwa Si mu chitsulo chosungunula kumapangitsa kuti C kuwonjezeke, ndibwino kuwonjezera chitsulo cha Si pambuyo pake, koma chimayambitsa chitsulo m’ng’anjo . Kuchedwa pakuwunika kwamadzi ndikusintha. Kuti

(6) Kusiya chitsulo chamadzi m’ng’anjo ikasungunuka kumatha kuthandizira kukonza magwiridwe antchito amagetsi amagetsi ndikuwonjezera mphamvu yamagawo osungunuka. Komabe, zitsulo zosungunulazi zitha kutenthedwa m’ng’anjo kwa nthawi yayitali ndikuyika pangozi chitsulocho. Chifukwa chake, chitsulo chosungunuka chotsalira chikuyenera kuwerengera 15% yamiyeso yamoto. Chitsulo chosungunuka pang’ono chimawonjezera kutentha, ndipo chitsulo chochuluka kwambiri chimachepetsa kugwiritsa ntchito chitsulo chosungunuka ndikuwonjezera mphamvu yamagetsi. Kuti

(7) Makulidwe amtunduwu makamaka 200 ～ 300mm. Kukula kwakukulu, kumachedwa kusungunuka.
