In the paper, the main influence factor for the large scrap quantity and low output per machine-hour when milling with HP type medium-speed mill of Iron-making Plant of Baotou Steel is determined to be the air inlet of nozzle ring through the research analysis on site. The scrap quantity is greatly reduced with three times of modifying nozzle ring so that the goals of increasing the output per machine-hour as well as energy saving and consumption reduction are achieved.
