Steel ladle anti-leakage early warning method and device for steelmaking continuous casting process and storage medium

Abstract

The invention provides a steel ladle anti-leakage early warning method and device for a steelmaking continuous casting process and a storage medium. The method comprises the steps that: temperature information of the outer surface of a steel ladle is obtained; a temperature value of a defect part is extracted, and back calculation is performed to solve a lining thickness; according to the solved lining thickness, a weight coefficient is set for an experienced process link to solve an erosion rate; the minimum safety thickness which enables the outer edge of the lining to be not broken is calculated according to a strength mechanics principle, and then the service life is predicted; and a steel ladle full-life-cycle bleed-out risk assessment system is established based on the minimum safetythickness, the erosion rate and technological link parameters, and a quantitative risk value is obtained to determine a leakage risk grade. The full-life-cycle anti-leakage risk assessment system isestablished, the current risk value is assessed, and important guiding significance is achieved for on-site package matching, turnover rate improving and service life prolonging.

Description

technical field [0001] The invention relates to the technical field of safety monitoring, in particular to a ladle anti-leakage early warning method, device and storage medium in the process of steelmaking and continuous casting. Background technique [0002] Ladle is a typical high-temperature molten metal storage and transportation container in the field of iron and steel metallurgy. Its refractory material is subjected to repeated chemical erosion and physical erosion by various thermal fluids such as steel slag, molten steel, argon, and oxygen. If it is not handled properly, it will lead to leakage of molten steel. and other large-scale production safety accidents. [0003] The key to the ladle leakage prevention and control technology lies in the accurate analysis of the melting loss behavior of the ladle wall refractory material and the accurate acquisition of the leakage pilot signal. However, the existing research results and technologies have defects in both aspect...

AI Technical Summary

Problems solved by technology

However, the existing research results and technologies have defects in both aspects. The corrosion mechanism of wall refractory materials is mostly concentrated on a single action such as chemical reaction or scouring, without considering the life cycle process experience of storage and transportation containers, and it is impossible to accurately analyze the erosion mechanism. Therefore, it is impossible to establish a correlation model between the wall surface temperature and the residual thickness, and it is impossible to accurately predict the residual thickness of the wall refractory material; another aspect of leakage prevention and control is the accurate acquisition of the wall surface temperature. The current single The absence of technologies such as infrared temperature measurement and temperature data fusion technology cannot adapt to the complex and harsh working environment on site, and it is also impossible to accurately obtain the wall temperature of the device; because the above-mentioned key technologies have not been really solved, the current application based on acoustic emission, based on Ladle leakage warning technologies such as infrared temperature measurement cannot meet the actual needs of metallurgical enterprises, and they have to adopt a regular off-line maintenance system, and leakage accidents occur from time to time
