Study on the participation of blowing CO2 in steelmaking reaction of Fe-C binary alloy

Abstract

Based on the concept of green low-carbon and high-efficiency smelting, Fe-C alloys were prepared using industrial pure iron and high-purity graphite powder, and thermal experiments were carried out using a high-tem perature tube furnace, and it was found that with the increase of blowing time, the carbon content in the molten pool was reduced subsequently; The reaction rates of CO2 with (C) were 11,03 %, 12,94 %, 16,51 %, and 18,75 % at blowing flow rates of 10, 20, 30, and 40/ml·min-1, respectively; The decarburization rate increased from 0,0172 %/min to 0,0289 %/min, and the decarburization reaction rate is subsequently increased 1,68 times.
