Furnace burden optimization method for iron-making system

Abstract

The invention relates to a furnace burden optimization method, and particularly relates to a comprehensive proportioning optimization method for sintered ores and blast furnace burdens. The comprehensive proportioning optimization method is a six-in-one furnace burden optimization method for an iron-making system, comprising sintered ore metallurgical performance detection and analysis, sintering process proportioning optimization, sintered ore ingredient predication and analysis, blast furnace burden structure optimization, blast furnace proportioning calculation, iron-making system furnace burden structure multi-target optimization; the optimal proportioning ratios and the optimal ingredients of the various furnace burdens of sintering proportioning and blast furnace proportioning are determined; the problems of limit to a certain procedure of ore blending, sintering and iron-making, high cost and instable quality of the existing iron-making furnace burden optimization method are solved. The furnace burden optimization method disclosed by the invention overall plans the whole iron-making process, highly scientifically analyses, plans and calculates from the whole system, furthest reduces the cost, and finds a furnace burden optimization scheme for an iron-making system, which is low in pig iron production cost, excellent in products and high in yield.

Description

technical field [0001] The invention relates to a furnace charge optimization method, in particular to a furnace charge optimization method for an ironmaking system. Background technique [0002] The ironmaking production process is a system engineering closely related to each process. At present, the cost of ironmaking in domestic iron and steel enterprises is very different. The cost per ton of iron varies from tens to hundreds of yuan. For an ordinary enterprise with an annual output of 5 million tons, the annual cost can vary from 100 million to several billion. The reason is that the difference in ingredient structure is a crucial factor in determining the cost. At present, there are many kinds of raw materials for ironmaking, complex components, and large price gaps. However, the existing methods for optimizing the structure of ironmaking furnace materials are limited to a certain process such as ore blending, sintering, and ironmaking, and lack overall system conside...
