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 the enveloping surface of blast furnace hearth bottom erosion, which relates to the technical field of blast furnace hearth bottom erosion detection. By adopting the method based on the invariant grid and the dimension approach method, according to the steady state of the blast furnace simulation model Based on the law assumption of state heat transfer, the characteristics of different dimensions of the blast furnace hearth and bottom model are simplified, and the simulation model of different dimensions is calculated considering the need for accuracy improvement. According to the hearth thermocouple monitoring data in different periods, the maximum temperature of the detection point is obtained. The obtained inner boundary of hearth and bottom is used as the initial condition of high dimension, so that the improvement of accuracy is transformed into the expansion of dimension. The difference in unit scale is ignored when the envelope surface is adjusted, and there is no need to solve the exact position of the erosion surface, forming a set of overall solutions for solving the envelope surface of the blast furnace, which improves the accuracy of the measurement results of the blast furnace erosion calculation and reduces the amount of calculation, thereby alleviating the The existing technology has the problems of large error in erosion detection results and large amount of calculation.

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...
