Characterization method, system, equipment and storage medium for blast furnace burden surface shape

Abstract

The invention provides a characterization method, a system, equipment and a storage medium for a blast furnace burden surface shape. The method comprises the following steps of, collecting basic data,wherein the basic data comprises equipment parameters of a bell-less furnace top, charge characteristic parameters and a charging matrix; simulating a material flow track to calculate the material flow width and coordinate of the falling point position of the charge; calculating the shape of the material surface formed by the burden falling at the inclination angle of each chute by using a finiteelement secondary method, and extracting characteristic parameters of the material surface according to the shape of the material surface; and calculating material distribution index characterizing the material surface shape and the material distribution matrix according to the material surface characteristic parameters. According to the characterization method, the material surface shape and thematerial distribution matrix information are accurately characterized, so that a material surface shape characterization reference is provided for an operator in an upper adjustment process, the material distribution system is facilitated to be accurately and timely adjusted, the gas flow distribution is improved, and stable and smooth blast furnace production is realized.

Description

technical field [0001] The invention relates to the technical field of blast furnace smelting control, in particular to a method, system, equipment and storage medium for characterizing the shape of a blast furnace material surface. Background technique [0002] The upper part adjustment is to control the combustion zone through the lower part and the reflow zone in the middle part to obtain a reasonable gas flow distribution under the condition of certain furnace type and raw material physical properties. In blast furnace throat, the distribution of gas mainly depends on the distribution of charge, so the distribution of gas can be controlled by cloth. Among them, the charging system constitutes the core of the adjustment of the upper part of the blast furnace. The charging system forms a reasonable shape of the material surface by adjusting the distribution ratio of ore and coke in the radial direction of the blast furnace, which affects the shape and composition of the re...
