Characterization of AlInP cladding layers with Mg and Si diffusion barriers for high-power red GaInP-AlGaInP laser diodes

During the converter steelmaking process, with an increase in the furnace life, the bottom blowing components will have different degrees of blockage. In this study, water model and numerical simulation experiments were performed to study the influence of the non-uniform bottom blowing gas supply mode on the dynamic properties of molten bath in a 300t converter. The results show that under the non-uniform bottom blowing gas supply mode, the mixing time, and velocity distribution characteristics were significantly improved compared with those of the clogging condition of the bottom blowing element. This gas supply mode was used in industrial tests, and sampling analysis was performed. The industrial experiments show that when the non-uniform gas supply mode is adopted, it helps accelerate decarburization and dephosphorization reactions, which reduces the endpoint carbon-oxygen equilibrium of molten steel and reduces the amount of ferrous oxide and the total iron content in endpoint slag.
