(5) smelting: when the materials in the step (4) are covered and the temperature reaches 1250 ℃, completely melting the materials, keeping the melting temperature at 1250 ℃, adding the electrolytic manganese obtained in the step (2), when no caking manganese exists in the electric furnace and no blue flame exists, indicating that the electrolytic manganese is completely melted, fishing out the slag in the electric furnace, modulating the power to 1000kw, keeping strong electromagnetic stirring for 30-50 s, sampling and analyzing components, and calculating and compensating until the components accord with BFe 10-1-1;
(6) refining and degassing: when the melt components in the step (5) meet BFe10-1-1, adding 0.1% Mg metal into the copper liquid, and stirring up and down by using an iron rod after the copper liquid does not emit twinkling sparks;
(7) casting: and (4) taking the copper liquid obtained in the step (6), stirring, and then starting casting to obtain a BFe10-1-1 ingot.
2. The method for producing the BFe10-1-1 ingot at low cost according to claim 1, wherein the method comprises the following steps: in the step (7), the casting temperature is 1265-1280 ℃, the casting speed is 45-48 mm/min, and the cooling water flow is controlled at 48-50 m3The water pressure is 400-550 kpa.
3. The method for producing the BFe10-1-1 ingot at low cost according to claim 1, wherein the method comprises the following steps: in the step (1), the burning loss of the Cu, Ni and Fe elements is not considered during the material proportioning calculation.
