“…1. Visualization of the cupola temperature profile by loading zones [7]: 1 -idle charge; 2 -metal charge; 3 -fuel charge; H -horizon level along the cupola furnace height, h -current coordinate along the cupola furnace height, h sh -horizon along the cupola furnace height, corresponding to the position of the upper level of the idle charge, h sh max -maximum horizon along the cupola height, corresponding to the minimum position of the upper level of the idle charge, h sh min -the minimum horizon along the height of the cupola, corresponding to the maximum position of the upper level of the idle charge, Δh + -the positive deviation of the upper level of the idle charge along the horizon, Δh --the negative deviation of the upper level of the idle charge along the horizon, T -the temperature in the cupola, T iron -the temperature of the cast iron when discharged from cupola furnaces…”
