Estimation Method of Charge Rate and Gas Flow Distribution in Blast Furnace

摘要

The present invention relates to a method for estimating charge strengthening speed and gas flow distribution in a blast furnace, and an object thereof is to provide a quick and accurate estimation of strengthening speed distribution and a method for estimating a dynamic gas flow distribution using the same. According to the present invention, the radial descent velocity distribution affecting the blast furnace shaft-to-gas distribution is categorized into several, and the radial gas flow distribution calculated in the charge distribution control model is measured at the top of the shaft. A method for estimating the radial load drop velocity distribution and the gas flow distribution by finding a form of the charge drop distribution in which the measured temperature distribution and the calculated gas flow distribution coincide with each other. That technical point.
