Visualization System of Accidents and Risk in Molten Metal Operations

In order to evaluate risk and prevent accidents, a visualization system of accidents and risk in molten metal operations is proposed in this paper. Based on risk identification and analysis, the system characterizes the evolution process of hazards, and realizes dynamic visualization and risk evaluation of accidents through fluid simulation and three-dimensional (3D) visualization technology. And on the basis of many times of simulation and attempts, risk decisions that are technically feasible, economically reasonable and socially acceptable can be obtained. The system consists of four functional subsystems: production scene roaming subsystem, hazards evolution characterization subsystem, accident dynamic visualization subsystem, risk evaluation and decision-making subsystem. The system is applied to the production safety management of a steel plant. The results show that it can realize accident preview, playback and risk evaluation, and make appropriate risk decisions based on different acceptable levels of risk. It provides new ideas and methods for production safety management.
