Embodiment Construction

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050] At present, the steady-state heat conduction solution mainly uses the adjustment of the grid boundary to determine the erosion surface, and each iteration needs to be re-meshed, which consumes a lot of resources. The traditional grid division method usually causes errors, and the operation method also causes errors in measurement results. Common computing hardware cannot meet ...

Abstract

The invention provides a method for determining a blast-furnace hearth bottom erosion envelope surface and relates to the technical field of blast-furnace hearth bottom erosion detection. The method has the advantages that a method based on unchanged grids and a dimensionality approaching method is used, different-dimensionality feature simplification is performed on blast-furnace hearth bottom models according to the rule hypothesis of steady-state heat transfer in blast-furnace simulation models, the needs of precision are considered, and the different-dimensionality simulation models are calculated; the highest temperature of detecting points is acquired according to hearth thermocouple monitoring data of different periods; precision increasing is converted into dimensionality expansionby using obtained hearth bottom inner boundary as the initial condition of high dimensionality; unit dimension differences are ignored during envelope surface regulation, the solving of the accurateposition of an erosion surface is not needed, an overall solution for solving a blast-furnace envelope surface is formed, the accuracy of blast-furnace erosion calculation measuring results is increased, calculation quantity is reduced at the same time, and the problems that erosion detection results are large in errors, and erosion detection is high in calculation quantity in the prior art are alleviated.

Description

technical field [0001] The invention relates to the technical field of detection of hearth bottom erosion of a blast furnace, in particular to a method for determining an erosion envelope surface of a hearth bottom of a blast furnace. Background technique [0002] After the blast furnace was put into production, the working conditions of the hearth bottom were particularly bad. As the part containing high-temperature molten iron, the hearth bottom was eroded by the physical and chemical effects of molten iron, and the erosion increased with the service time. Blast furnace safety production and economic and technical indicators are of great significance. [0003] In the process of realizing the present invention, the inventors have found at least the following problems in the prior art: currently, there are mainly two typical lining structures in the field of blast furnace: heat conduction lining and refractory lining. The degree of lining ablation can be judged through test...
