METHOD FOR CONTROL OF BLOWING CONDITION IN OXIGEN VESSEL

摘要

A method for control of blowing condition in oxygen vessel, at which decarbonization rate of vessel bath, amplitude and vibration frequency of gas pressure in working space of vessel are measuring, reburning degree of CO to COin vessel hollow is determined and distance of lance to level of killed metal is changed on measurement results of covering-forming,and oxygen supply intensive into vessel bath is changed on determine results of reburning degree of CO to COin vessel hollow.
