Method for optimizing parameter of high phosphorus iron ore smelting process

Abstract

The invention discloses a method for optimizing a parameter of a high phosphorus iron ore smelting process. The method is mainly applied to selection and design of the parameter of the high phosphorus iron ore smelting process. The method comprises the following steps of: (1) placing a sample having different proportions (or granularities, carbon proportions and temperatures of ore powder) on a thermogravimetry analyzer and performing a dynamics experiment; (2) acquiring thermal data of differential thermal quantity at a certain interval; (3) making a time sequence table according to the acquired data and putting the time sequence table into used software for analysis; and (4) judging a smelting effect according to an image characteristic so as to determine the best process parameter. As the method is applied to the optimization of the smelting parameter, the method is simple and convenient, and has high practical value; and a reliable and practical detection and experiment method is provided for the optimization of various smelting parameters of high phosphorus iron ore. By the method, the shortcoming of the conventional muffle furnace experiment is solved; moreover, the cost and the material consumption are low, so the energy is saved and the emission is reduced; and a special representation measure for converting dispersed data into an image is adopted.

Description

technical field [0001] The invention relates to the fields of metallurgy and chemical engineering technology, statistics and digital image processing, and specifically relates to a method suitable for optimizing process parameters of high-phosphorus ore iron and steel smelting. Background technique [0002] Process parameters refer to a series of basic data or indicators of the process of completing a certain work, that is to say, these basic parameters constitute the content of process operation or design. Process parameters such as alkalinity, carbon ratio, temperature, particle size, and composition factors in high-phosphorus ore iron and steel smelting usually need to be obtained through muffle furnace experiments, which require a large number of small and medium experiments and consume a lot of energy and materials, such as steel Among them, a large amount of crucibles need to be bought.

Process parameters such as alkalinity, carbon ratio, temperature, particle size, and composition factors in high-phosphorus ore iron and steel smelting usually need to be obtained through muffle furnace experiments, which require a large number of small and medium experiments and consume a lot of energy and materials, such as steel Among them, a large number of crucibles need to be purchased. In many cases, the corrosion of the crucible has caused the crucible to be unusable and the pollution is also very serious.

A large amount of dense smoke and volatile and harmful gases discharged in the experiment have posed a serious threat to human health and life safety. At present, it is an important period for energy conservation and emission reduction. The country advocates low-carbon economy, but without passing the experiment and Unable to get optimization for these parameters

However, the muffle furnace experiment cannot observe the dynamic changes of its smelting
