Burden surface profile control method of blast furnace burden distribution and control system

Abstract

The invention discloses a control method of a burden surface profile control method of blast furnace burden distribution, and the method comprises: measuring the height variation of 6 specified points on the burden surface by radars; measuring the burden surface height values of the 6 specified points when the radars measure that the heights of the 6 specified points on the burden surface reach predetermined heights; calculating an ideal burden surface profile on the basis of current burden distribution parameters of burden distribution equipment, with the ideal burden surface profile containing the ideal burden surface height values of the 6 specified points; generating a burden distribution matrix based on the ideal burden surface profile; on the basis of the 6 specified points, revising the ideal burden surface profile according to the differences between the current burden surface height values and the ideal burden surface height values of the 6 specified points, thus obtaining a revised burden distribution matrix and revised burden distribution parameters of the burden distribution equipment; conducting burden distribution equipment based on the revised burden distribution parameters of the burden distribution equipment. The burden surface profile control method and control system of blast furnace burden distribution of the invention can realize more accurate detection of the burden surface, enable more optimized burden distribution process, reduce burden surface fluctuation, and achieve stable production, energy saving as well as consumption reduction.

Description

technical field [0001] The invention relates to the field of metallurgical technology control, in particular to a material surface shape control method and control system for blast furnace material distribution. Background technique [0002] The iron and steel industry is an important basic industrial sector and the material basis for the development of the national economy and national defense. The ironmaking process is a very complex chemical reaction process, and the production conditions inside the blast furnace are very harsh. How to make better use of the existing theory and monitoring information to realize the on-line control of the blast furnace smelting process has become a matter of great concern to the iron and steel industry. [0003] The blast furnace smelting process has a very close relationship with the shape of the material surface in the furnace. By monitoring the shape of the material surface, the smelting process can be well grasped, and then the accur...

Problems solved by technology

This application studies the method of using multiple radars to detect the shape of the blast furnace charge surface. The system uses the height data converted by multiple radars as the standard, and the height data measured by the mechanical probe as a reference, but the system is only a measurement system. As the key data for the formation of the material level, the six-point radar plays a role in the reconstruction of the material level, and the radar does not participate in the control of the material level
