摘要
通过冷态和热态试验、研究转炉底喷粉剂的输送特性，初步认为：喷粉压力应大于０．５ＭＰａ；冶炼过程中不停喷，可通过调整罐压和载气量控制喷粉过程；粉气出口速度应大于３００ｍ／ｓ，提高气流速度，有利于减少喷粉过程的脉动。
t is demonstrated through cold and hot state tests on the characteristics of feeding the bottom injectant for the converter that the pressure for powder injection shall exceed 0.5 mpa;the injecting operation proceed continually without interruption and may be controlled by appropriately adjusting the pressure in the injection pot and the volume of carrier gas; the outlet velocity for both gas and powder be maintained at over 300m/s; and an increase in the gas flow velocity will help reduce pulsa-tion over the powder injection.
