Mfundo zazikuluzikulu zowongolera njira mukasungunula chitsulo mu ng’anjo yosungunula

Mfundo zazikuluzikulu za kayendetsedwe ka ndondomeko pamene zikulimbikitsidwa kugwiritsa ntchito chowotcha kutentha kusungunula chitsulo chosungunuka ndi motere:

1. Kuchuluka kwa ingots zachitsulo za nkhumba zomwe zimaperekedwa siziyenera kupitirira 20%, makamaka kuzungulira 10%;

2. Mu recarburizer yowonjezeredwa ndi malipiro, ndi bwino kukhala ndi gawo lina (40-55%) la metallurgical silicon carbide;

3. Chitani mosamala chithandizo cha inoculation panthawi yachitsulo, ndikusankha ma jekeseni oyenerera malinga ndi momwe ntchitoyo ikupangidwira. Kuchuluka kwa ma inoculants owonjezera kuyenera kukhala 0.1-0.2% kuposa momwe amasungunula kapu. Mtengo wabwino kwambiri uyenera kupitilira zotsatira za mayeso am’munda. Zedi;

4. Iyenera kulumikizidwa nthawi yomweyo panthawi yothira;

5. Popanga castings ndi zofunika apamwamba, metallurgical pakachitsulo carbide ayenera kuwonjezeredwa ku ng’anjo kwa pretreatment pamaso pogogoda.
