Embodiment Construction
[0044] Below in conjunction with embodiment the present invention is further described. However, the uses and purposes of these exemplary embodiments are only used to illustrate the present invention, and do not constitute any form of limitation to the actual protection scope of the present invention, nor limit the protection scope of the present invention thereto.
[0045] The invention provides a steelmaking method, comprising the following steps:
[0046] 1. Furnace charging
[0047] (1). Determine the loading amount:
[0048] Furnace times for leaving steel and slag: charging amount = 0.85 × (tapping amount - ferroalloy amount) / comprehensive yield of iron and steel materials
[0049] Steel slag removal furnace times: charging amount = 0.85 × (tapping amount - ferroalloy amount - remaining steel amount in the furnace) / comprehensive yield of iron and steel materials
[0050] The first furnace of the empty furnace: charging amount = 0.85 × (tapping amount of steel - ferr...
