Method for realizing fine analysis of iron ore sintering simulation test through process pause

Abstract

The invention relates to a method for realizing fine analysis of an iron ore sintering simulation test through process pause. In the test process of a sample material before the sample material is fired, stage slitting of the process is realized through different process conditions, so that the sintering process is paused at a certain stage and qualitative analysis is performed for the stage; anda final sintering scheme is analyzed and adjusted according to process parameters and intermediate results of various stages. The invention provides a refined analysis means for adjusting a batching and sintering scheme of a sintering simulation test, which reduces the ineffective test quantity, provides an unprecedented process parameter for the result of a sintered finished product, realizes thevisualization of important process parameters, and provides a stronger support for the sintering theory and practice.

Description

technical field [0001] The invention relates to the technical field of iron ore powder agglomeration, in particular to a method for realizing fine analysis by suspending the process of an iron ore sintering simulation test. Background technique [0002] Iron ore powder sintering is a block making process widely used in the iron and steel industry. The main purpose is to provide high-quality charge for blast furnace ironmaking. Low-grade iron ore resources are optimized through sintering, and fluxes are added during the sintering process to improve metallurgical properties such as reducibility, high-temperature softening and melting. Affected by the source of iron ore, to achieve reasonable optimization at this stage must be carried out by means of simulation tests. [0003] The conventional sintering simulation test method is to put the iron ore powder into the sintering cup for sintering after pretreatment, and perform various detection, analysis, evaluation and verificati...

Problems solved by technology

Due to the need to repeat multiple experiments, and the error of the experiment itself is very large, whether a change in a variable has an impact on the final result, and how much impact it has, is covered by the experimental error in many cases, which is also a routine Defects that always exist in sintering tests

In this case, it is necessary to evaluate the final results after firing for each test to determine whether the scheme of each test is effective, but this approach often has little effect, or it is necessary to make a comparison of the batching structure or the sintering scheme. Only after major adjustments can it be reflected in the changes in the results, during which a lot of manpower and material resources were wasted
