A method for improving the pressure fluctuation control process of oxygen pipeline network

Abstract

The invention relates to a method for improving the pressure fluctuation control process of an oxygen pipe network. A dynamic prediction model of oxygen consumption flow is established. The dynamic prediction model of oxygen consumption flow includes a converter oxygen consumption flow model, a blast furnace oxygen consumption flow model, a total oxygen consumption flow model, a ball Tank pressure calculation model; the upper limit of the spherical tank pressure is set to 2.2Mpa, and the lower limit is set to 1.4Mpa. When the predicted value of the spherical tank pressure exceeds 2.2Mpa or is lower than 1.4Mpa, the result will be fed back to the oxygen generator operator to remind them Relevant adjustments are made to establish an optimization strategy for oxygen dynamic supply and demand balance scheduling. The invention reduces the oxygen release rate, reduces the commissioning time of the vaporization equipment, and at the same time, by establishing a corresponding software system, eliminates hidden dangers in information transmission, makes equipment operation information transparent, solidifies relevant algorithms, and improves the accuracy of oxygen consumption prediction. It provides a more accurate reference for oxygen equipment operators, and optimizes the oxygen pipeline network pressure fluctuation control process.

Description

technical field [0001] The invention belongs to the technical field of steelmaking production optimization, and in particular relates to a method for improving the pressure fluctuation control process of an oxygen pipe network. Background technique [0002] In the steelmaking process, high-purity oxygen needs to be injected, which helps to reduce the carbon content of the steel, remove impurities such as phosphorus, sulfur, and silicon, and at the same time, the heat generated by oxidation maintains the temperature required for the steelmaking process, effectively shortening the smelting time and improving steel quality. The design of the oxygen and nitrogen gas supply system is statically balanced according to the average consumption of gas in the iron and steel process, but in actual production, the dynamic balance of oxygen supply and demand reflects the essence of a steel plant's oxygen supply system balance. Oxygen consumption in steelmaking varies with changes in prod...

Problems solved by technology

The defect of the existing scheme is mainly manifested in the fact that the actual production situation of the relevant oxygen-consuming equipment cannot be grasped in time. The prediction accuracy of the oxygen output of the oxygen production equipment, which in turn leads to a large deviation in the pressure fluctuation of the oxygen spherical tank
