Converter on-line diagnosis energy-saving and consumption-reducing SADS system

Abstract

Disclosed is a converter on-line diagnosis energy-saving and consumption-reducing SADS system. The system solves the problems that in the existing converter steelmaking process, the heat recovery rateof converter gas is low, the energy consumption of converter steelmaking is high, and the gas generated by a converter cannot be effectively utilized. The system is based on a multi-signal-source process analysis means, depends on a metallurgical physicochemical model algorithm in the converter steelmaking process, and guarantees that the converter gas recovery amount and the converter gas heat value are always in an ideal state in the converter steelmaking process through self-adaptive calculation and intelligent analysis, and the converter gas recovery heat is made maximum. Moreover, the optimal converter steelmaking production process rhythm is provided, and the process rhythm not only ensures smooth operation of the steelmaking process but also ensures the maximization of gas recoveryheat. Under the condition that the use amount of the gas consumption end is kept unchanged, more gas can be used for gas-fired boiler power generation, and greater economic benefits can be created for a steel mill.

Description

technical field [0001] The invention belongs to the technical field of metallurgy automation, and specifically relates to a method that can improve the heat recovery of converter gas, reduce the energy consumption of converter steelmaking, and use more gas generated by the converter to generate electricity in a gas-fired boiler to increase the power generation capacity of gas-fired power generation. On-line diagnosis and analysis of the technology in the steel process to reduce the occurrence of some accidents in the converter online diagnosis energy-saving and consumption-reducing SADS system. Background technique [0002] The converter steelmaking process is a process of decarburizing the molten iron entering the converter, and finally the molten iron reaches the target through chemical reaction to produce qualified molten steel. During this process, converter gas is intermittently recovered from the top of the converter as a by-product gas. Since the energy carried by th...
