The drawing illustrates and briefly analyzes the changing law of the decarburization rate during the blowing process.- steelmaking decarburization
Keywords: steelmaking decarburization
In the early stage of blowing, due to the greater affinity between Si and oxygen, Si rapidly oxidizes, and the decarburization rate is small. As the oxidation of Si ends and the temperature of the molten pool rises, it enters the second stage, that is, the intense oxidation period of carbon. In the second stage, the decarburization rate is controlled by the oxygen supply intensity. When the oxygen supply intensity is basically unchanged, the decarburization rate is almost constant. When the carbon is reduced to a certain level, the diffusion of carbon is the restrictive link of the reaction. , So as the carbon content decreases, the decarburization rate decreases. As shown on the right.- steelmaking decarburization
