The invention belongs to the technical field of converter steel making and particularly provides a converter bottom blow pipe state monitoring system comprising a bottom blow main pipe and multiple bottom blow branch pipes. The bottom blow branch pipes are connected with the bottom blow main pipe. The converter bottom blow pipe state monitoring system further comprises a pressure monitoring module, a sound-light alarm module and a display module. The pressure monitoring module is used for collecting a pressure value on each bottom blow branch pipe. The sound-light alarm module is used for judging whether the pressure value on each bottom blow branch pipe exceeds a preset safety value section or not, and if yes, the sound-light alarm module gives out a sound and light alarm on the corresponding bottom branch pipe. The display module is used for displaying the pressure value and the alarm state on each bottom blow branch pipe. The converter bottom blow pipe state monitoring system has the functions of automatically detecting abnormality of each bottom blow branch pipe and giving an alarm in time and can avoid the situation that expansion of a gas leakage point causes blockage of a gas outlet at the bottom of the converter; and the defects that a ventilation pipeline cannot be detected in time, and a small leakage point is difficult to find can be made up, and the cost and qualityloss of converter molten steel smelting caused by blockage of a bottom blow hole is reduced.
Description
technical field [0001] The invention belongs to the technical field of converter steelmaking, and in particular relates to a converter bottom blowing pipeline state monitoring system. Background technique [0002] A good bottom blowing effect is the key to reduce the final slag T.Fe (full iron) of the converter, improve the dephosphorization rate of the converter terminal and reduce the carbon and oxygen accumulation. In order to ensure the reblowing effect of the converter, the advanced steel mills at home and abroad pursue the effective reblowing of the converter at the expense of the furnace life. However, the production environment of the converter is complex, and the bottom blowing system will continue to work after the start of the new furnace operation, and it will always be in a high-pressure environment. This requires high requirements for various metal hoses in the bottom blowing system, especially the connection between the bottom of the furnace and the bottom blo...
