Problems solved by technology

However, on the one hand, due to the geometry reconstruction and grid division involved, when the hearth erosion curve has slender erosion, irregular erosion and other irregular erosion states, the mesh reconstruction will often fail, so the stability of the model calculation Poor, the stability of the model is difficult to meet the needs of the site
On the other hand, since thousands of iterations are required to predict each erosion curve, if geometry and mesh reconstruction are performed for each iteration, the calculation amount is large and the calculation time is long, and it is difficult to meet the on-site calculation requirements. real-time requirements

Embodiment 1

[0020] First, the problems with the current technology are addressed. The identification of hearth erosion involves geometry reconstruction and grid division. When the hearth erosion curve has slender erosion, irregular erosion and other irregular erosion states, the mesh reconstruction will often fail. Therefore, the grid nodes adopt a topological structure, which not only makes the identification process clearer, but also facilitates programming and improves computational efficiency.

[0021] Further, the calculation of the nonlinear optimization module is performed, and data results such as erosion boundary and temperature field are output. Since thousands of iterations are required to predict each erosion curve, if the geometry and mesh are reconstructed for each iteration, the amount of calculation will be large and the calculation time will be long, which is difficult to meet the real-time requirements of the calculation on site . Therefore, the calculation process fir...

Abstract

The invention discloses a hearth erosion identification method, electronic equipment and a storage medium, and belongs to the field of blast furnace ironmaking. The method comprises the following steps: 1, representing a hearth model in a two-dimensional coordinate manner, constructing a two-dimensional finite element model, and measuring to obtain an initial erosion boundary; 2, performing finite element heat transfer calculation according to the erosion boundary to obtain a root-mean-square rms of a deviation between a calculated value and a measured value of a temperature measurement point, and calculating an erosion degree; 3, judging according to a root-mean-square rms result, outputting if a condition is met, adjusting the erosion boundary if the condition is not met, and returning to the step 2. The second step and the third step are sequentially executed for multiple times, and finally hearth erosion recognition and detection are completed. The invention provides an accurate and efficient hearth erosion identification method, and develops a hearth erosion online identification model with strong calculation stability and high calculation efficiency.

Description

technical field [0001] The invention relates to the field of blast furnace ironmaking, in particular to an online identification method for hearth erosion. Background technique [0002] With the development of ironmaking technology, people pay more and more attention to the longevity of blast furnace. However, the hearth and bottom of the blast furnace work in harsh environments such as high temperature and high pressure for a long time, and they are washed away by high-temperature molten iron and damaged by thermal stress for a long time; therefore, during the operation and production process of the blast furnace, the erosion of the hearth and bottom has become Weak link in blast furnace longevity. Since the blast furnace is a closed container involving high temperature and high pressure, it is difficult for people to know the real erosion state of the hearth refractory material in actual production, so major accidents of blast furnace hearth burn-through occur from time t...
