Original title: Fangda Jiu Steel’s steelmaking plant has achieved results in reducing low-pressure nitrogen consumption in the western zone
Since January 2021, Fangda JiugangSteelworksFrommanagement、Craft, Equipment and other aspects to increase efforts to tackle the problem of low pressure nitrogen in the western zone, prompting a significant drop in the consumption of low pressure nitrogen in the western zone of the steelmaking plant. The consumption has dropped from 23 cubic meters per ton of steel to 19.3 cubic meters per ton of steel. The research has achieved remarkable results.
At the end of December 2020, the steelmaking plant required the equipment department to compare the low-pressure nitrogen consumption parameter indicators in the east and west areas to find out the reasons for the excessive low-pressure nitrogen consumption in the west area, and to reduce the consumption of low-pressure nitrogen in the west area through key research methods.The equipment department immediately organized the first workshop of the converter and prepared the relevant personnel of the workshop to hold a special meeting on reducing low-pressure nitrogen consumption. Everyone worked together to reduce consumption from the following aspects: firstly, from the process aspect, the two converters in the first workshop of the converter were sealed with nitrogen. To cancel the processing, the nitrogen can be cut off, and only the nitrogen seal of the discharge port of the centralized silo is reserved; secondly, the nitrogen control program of the discharge pipe of the centralized silo is optimized from the equipment: the nitrogen seal of the discharge port is changed from the originallongManual opening is changed to automatic control, and works with the converter workshopoptimized controlProgram, in the molten iron, smelting mode or slag splashing mode, when the gun position is less than 5.5 meters, the nitrogen is automatically turned on, and when the gun position is greater than 5.5 meters in the smelting mode or slag splashing mode, or in the maintenance mode, the nitrogen gas is turned off; in addition, the technical personnel refer to the east area The nitrogen flow at the feed outlet was adjusted appropriately to achieve the optimal mode; management was carried out to find the leaks of low pressure nitrogen and block the leaks, focusing on the remediation of the leaks of the three-time water and dust pulse back-blowing in the west area.
Through the above research measures, the low-pressure nitrogen consumption has achieved obvious results. In January, the ton of steel decreased by 3.7 cubic meters per ton of steel nitrogen, which can save the steel plant every monthcostAbout 50,000 yuan.
