Example Embodiment

[0069] The principles and features of the invention are described below in combination with the accompanying drawings. The examples are only used to explain the invention and are not used to limit the scope of the invention.

[0070] from Figure 1 As shown in, a calculation method of fuel distribution in sintered granulation pellets comprises the following steps:

[0071] In step S1, the effects of raw material properties and granulation moisture on the distribution coefficient of each component are mainly considered. M sintering raw materials are mixed in a certain proportion through the granulation process, and the distribution coefficient is adopted based on the layered growth mechanism α (x) Describe the probability that each component acts as a nuclear particle, and consider the -0.5mm particle in the raw material as the adhesive layer of the granulation ball. When the moisture content of the customized particles is given, the average particle size of the adhesive layer parti...

Abstract

The invention discloses a method for calculating fuel distribution in sintered granulated pellets, which comprises the following steps of: calculating the property characteristics of the granulated pellets of each size fraction when an ore blending structure is given according to the influence of the ore blending structure and granulation moisture on the distribution coefficient of each component; the distribution conditions of the granulated raw material components in different granulated small balls are analyzed according to the three conditions that the size fractions of the raw material components are divided into the maximum size fraction, the adhesion layer size fraction and the middle size fraction; and calculating the proportion of the coke powder in the granulated pellets of each size fraction and the mass fraction of the granulated pellets of each size fraction when the ore blending structure is given by combining the distribution of the coke powder in the raw material in the ore blending structure, and calculating the fuel distribution of the granulated pellets. According to the method, a novel fuel distribution calculation method is established according to a mechanism model, a basis is provided for efficient utilization of sintering fuel, and the method has important application value.

Description

technical field [0001] The invention relates to a calculation method for fuel distribution, in particular to a calculation method for fuel distribution in sintered granulation pellets, and belongs to the field of iron and steel metallurgy. Background technique [0002] As a big country in steel production and consumption, my country's efficient use of fossil fuels is one of the important ways for the steel industry to achieve "carbon peak". As the first high-temperature process in the steel industry, sintering ranks second in the energy consumption of the entire steel production, accounting for about 10% of the total energy consumption, of which about 70-80% comes from solid fuel consumption. Therefore, in order to achieve energy saving and consumption reduction in the sintering process, the company has implemented a series of technologies including source emission reduction, process control and end treatment, among which fine use of fuel is an important development directio...
