Embodiment
[0033] This embodiment provides two groups of techniques for smelting steel using the method of the present invention, such as examples 1 and 2; simultaneously, a group of techniques for using the traditional electric furnace oxidation method for bottomless blowing of the same kind of steel is provided, such as comparative example 3, and the specific smelting process includes Follow the steps below:
[0034] 1. Leave a furnace for smelting steel in the electric furnace, then add auxiliary materials and scrap steel materials into the furnace, and melt the materials after electrifying the furnace, and add carbon powder during the melting process of the materials, and blow oxygen into the furnace at the same time, the specific process parameters As shown in Table 1.
[0035] Table 1 EAF steelmaking process parameters
[0036]
[0037] 2. Examples 1 and 2, the bottom blowing gas mode is used in the smelting process, and N is used when the blowing starts to 1 / 3 stage 2 , the c...
