Habka xisaabinta maaddooyinka ay ka kooban tahay foornada induction ramming walxaha:

1. Batching Quantity = rarista tirada-wadarta tirada gelinta ferroalloy-iron tirada birta-hadhay ee ku soo celinta foornada;

2. Qadarka soo-kabashada = qaddarka garaacista / heerka soo kabashada birta oo dhammaystiran;

3. Qadarka galinta macdanta birta = qadarka dheeriga ah ee birta × maadada birta × heerka dakhliga birta. Qadarka dheeriga ah ee macdanta guud ahaan waxaa lagu xisaabiyaa 4% ee mugga garaaca, maadada birta ee macdanta waa 55%, iyo heerka soo kabashada birta Marka loo eego soo kabashada 80%, wadarta guud ee heerka soo kabashada dhamaystiran ee kharashka ayaa isbeddelaya inta u dhaxaysa 92 ~ 96%, waxaana guud ahaan lagu xisaabiyaa 94%.
