Device and method for judging leakage amount of ladle bottom blowing pipeline

Abstract

The invention provides a device for judging leakage amount of a ladle bottom blowing pipeline. The device comprises an argon control system, an argon delivery pipeline, a ladle vehicle carried with ladles, and a leakage detection control valve, wherein the leakage detection control valve is arranged at the end of the argon delivery pipeline, near the ladles. The device for judging the leakage amount of the ladle bottom blowing pipeline adopts a method that a cutoff valve is opened, and if the flow quantity stabilized by a flow quantity adjusting device is 0N1 / min, the argon delivery pipeline has no leakage point; if the flow quantity stabilized by the flow quantity adjusting device is greater than 0N1 / min, the argon delivery pipeline has a leakage point, and the greater the value is, and the greater the leakage amount is; and if the flow quantity stabilized by the flow quantity adjusting device is smaller than 30N1 / min, the production requirements are met, and the finding of a leakage point is not required. The device and the method for judging the leakage amount of the ladle bottom blowing pipeline have the advantages that the leakage point of the ladle bottom blowing pipeline can be quickly judged, the labor strength of operators is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of iron and steel metallurgy, in particular to a device and method for judging the leakage of a ladle bottom blowing pipeline. Background technique [0002] At present, in the molten steel refining process technology outside the furnace, argon blowing and stirring is widely used as a means of refining in ladle blowing argon, LF, VAD, VOD, CAS-OB and other refining processes. The reaction interface can be enlarged and accelerated by argon blowing and stirring. The reaction process can improve the reaction speed, and the use of argon blowing at the bottom of the ladle is more common. Since the bottom blowing of the ladle requires argon to reach a certain pressure and flow rate in order to obtain the required metallurgical effect, generally the control and adjustment device of the bottom blowing argon is far away from the ladle, and the gas pipeline is mostly in the air, and consists of metal hard pipes and Composed of ...

Problems solved by technology

Since the bottom blowing of the ladle requires argon to reach a certain pressure and flow rate in order to obtain the required metallurgical effect, generally the control and adjustment device of the bottom blowing argon is far away from the ladle, and the gas pipeline is mostly in the air, and consists of metal hard pipes and Composed of metal hoses, metal hoses are subjected to stretching, bending and high-temperature steel slag splashing during use, and air leakage occurs after investigation. Once it is not found in time, it will have a great impact on the quality of molten steel and steelmaking production
