Renovation of evacuation facilities in case of leakage of high-temperature molten metal

In this paper, the renovation design of the evacuation facility in the high-temperature molten aluminum casting workshop was designed by the research team of the State Key Laboratory of Fire Science, University of Science and Technology of China to deal with the impact of high-temperature molten metal leakage and diffusion accidents. The field experiment results show that the evacuation path of the mixed furnace eye worker and the crane driver is severely blocked. In response to this problem, the evacuation escalator and evacuation slide were respectively designed during the renovation, and the evacuation path after the renovation was re-planned. According to the numerical simulation results, the new evacuation system has made great progress, and the efficiency of evacuation of people has been significantly improved. The current research provides a model for the reconstruction of the personnel evacuation system in the existing metallurgical workshop accident scene, which has great practical value for ensuring the safety of high-temperature molten metal operations.
