SynopsisBaowu’s Taiyuan Iron and Steel Corporation achieves a breakthrough in steel production with the introduction of the first domestic LTS automatic slag removal machine. This pioneering technology combines machine vision, intelligent sensors, deep learning, and automation to seamlessly separate slag from stainless steel molten metal. The system enhances efficiency, reduces human intervention, and significantly improves workplace safety.ArticleOn August 15th, Taiyuan Iron and Steel Corporation's Steel Mill #2 witnessed a historic moment with the inauguration of the first-ever domestic LTS automatic slag removal machine. This innovation marks a significant leap forward in steel production, specifically in the realm of stainless steel molten metal and slag separation.The system integrates cutting-edge technologies such as machine vision, intelligent sensors, deep learning, and automatic control to create a seamless and highly efficient slag removal process. Operators in the control room can initiate the automatic slag removal with a single click. Once activated, the steel ladle's automatic tipping mechanism tilts it to the pre-calculated initial angle.Upon reaching the correct position, the image analysis system intelligently captures and assesses the distribution of slag and determines the optimal path for the slag removal machine. The slag removal machine receives precise positioning instructions from the central computer and commences its automated slag removal operation. Throughout this process, the slag removal machine continuously adjusts its actions and posture based on real-time feedback from sensors. Simultaneously, the tilt angle of the steel ladle adapts to the changing molten metal level, while the image system continuously monitors the slag distribution. It uses different steel grade standards to determine when the slag removal process should conclude.The complexity of the stainless steel automatic slag removal system lies in the challenge of distinguishing between stainless steel molten metal and slag. During the slag removal process, slag continually forms, and the temperature of slag and molten metal is closely aligned, making it challenging to achieve accurate identification. However, the project team persevered for several months, meticulously analyzing slag removal data and applying machine vision and deep learning techniques. They continuously optimized mathematical models, accumulated experience, and refined algorithms. Ultimately, they achieved the remarkable feat of one-click automatic slag removal for stainless steel molten metal.This achievement has far-reaching implications. It not only eliminates the influence of human factors in the slag removal process but also enhances the yield of molten steel and ensures a safer working environment. Workers are liberated from the demanding and hazardous "3D" positions, contributing significantly to the overall improvement of safety in the workplace.ConclusionTaiyuan Iron and Steel Corporation's introduction of the first domestic LTS automatic slag removal machine is a testament to innovation in the steel industry. This breakthrough not only streamlines the steel production process but also enhances efficiency and safety. By leveraging cutting-edge technologies like machine vision and deep learning, Taiyuan Steel is setting new standards in the steel manufacturing sector.
