Abstract
The invention relates to a method for dynamically judging the state of slags in the converter smelting process and belongs to the technical field of metallurgy converter control. The technical scheme adopted by the invention is that the method comprises the following steps of transmitting information about the mass of an oxygen lance, oxygen flow, flue gas flow, noises in a converter as well as the concentrations of CO and CO2 in flue gases which are outputted in real time to a computer for detecting the state of the slags through an intermediate information PLC (Programmable Logic Controller); performing composite dynamic analysis on the information by using a built-in model in the computer; comprehensively judging whether the slags are in a partially-dry or partially-diluted state at the current moment; and sending a risk early warning that the slags get dry or slop, and timely processing. According to the method disclosed by the invention, on the basis of an original application of equipment which is arranged on a 120-ton converter at the production site, relational factors between the state of the slags in the converter smelting process and the information acquired by the equipment are fully considered, the factors are fused, the characteristics of various factors are fully exerted, and composite dynamic detection for the state of the slags from the 120-ton converter is realized; and on the premise of reducing the cost of the equipment, the risk early warning that the slags get dry or slop in the converting smelting process is realized.
