METHOD FOR DETECTION OF LEAKS IN LANCE DURING MELT BLOWING IN LADLE WITH GAS Russian patent published in 1998 - IPC

Abstract RU 2113507 C1

FIELD: metallurgy. SUBSTANCE: in case of pressure drop before lance below the threshold value, in the course of melt blowing in ladle with inert gas, position of lance is changed. Lance is raised in time for a preset time, and response by the value of pressure variation is analyzed. When pressure drops to value below the preset threshold, presence of leaks is stated; in case of pressure rise exceeding the threshold value, leaks are absent in gas conduit. Lance is returned to the initial position, and the process of blowing of melt in ladle is continued. EFFECT: saving of inert gas due to timely detection and elimination of leaks in gas pipeline, replacement of failed lance and higher efficiency of melt blowing by optimization of blowing conditions. 2 dwg
