Abstract

The invention relates to a method for measuring a deformation condition of a bulk material interfacial effect of a material distribution model of a blast furnace and belongs to the technical field of model test measurement of metallurgical industry. According to the technical scheme, the method comprises the following steps of: before material distribution, spraying two kinds of dyeing tracer agents with different colors onto the surfaces of sintering ores and cokes respectively to dye different colors on the surfaces of the sintering ores and cokes so as to facilitate the subsequent observation, cutting furnace charges by using a special cutter, separating and weighing to finish the material distribution interfacial effect deformation test of the material distribution model of the blast furnace. The method has the advantages that the method is convenient and intuitive, and wide in application field and easy to operate; the deformation condition can be measured accurately; test materials and furnace charges are saved, the test working amount is reduced, the distribution rule of the section shapes of the bulk materials can be resolved specifically; and the method is a very practical method for researching the material distribution rule in the model a laboratory.

Description

technical field [0001] The invention relates to a method for measuring the deformation state of the interface effect of bulk material in a blast furnace material distribution model, and belongs to the technical field of model test measurement in the metallurgical industry. Background technique [0002] When the blast furnace distribution model test is carried out in the metallurgical laboratory, the distribution work is often carried out, that is, different bulk materials such as sinter and coke are distributed in batches according to the material system of the production site. Due to the difference in the particle size of sinter and coke, this is Interface effects occur. The interface effect refers to the interaction of different charges on the material surface, mainly including two aspects of mixing (ie penetration) and deformation (rolling), which have an impact on the shape of the material surface of the cloth. The defects it brings to the blast furnace operation are: f...

AI Technical Summary

Problems solved by technology

The defects it brings to the blast furnace operation are: firstly, it destroys the layered structure of the charge and complicates the operation of the charge; secondly, because the interpenetration on the interaction interface between ore and coke is inevitable, it is difficult for the material column to breathe. There will be an adverse effect on the interfacial effect, that is, the part of the mixed layer thickness in the interface effect has poor air permeability

In short, the defect of the interface effect is that the surface shape of the ore coke material changes. In addition, the colors of the scattered materials such as sinter and coke are similar, which is not easy to distinguish with the naked eye, and segregation and rolling occur when deformation occurs. It is more difficult to study interface effects and adjust to a reasonable material surface shape
