Abstract:The steel industry is the foundation of social expansion and reproduction, it accounts for a large proportion of industrial water. The steel industry has brought great challenges to regional water shortages and industry water competition under the current contradiction between supply and demand of water resources. The solution to the problem is to deeply analyze the water use process of the steel industry, and to explore the water-saving potential of each link with refined water-saving evaluation. The process of water utilization in the steel industry is expressed through components and knowledge graphs, involving source, use, drainage and so on. Finally, it is be displayed on the integration platform. And it takes the water utilization for coking process in the steel industry as an example to introduce how to draw and evaluate for water saving. The results show that visualization is beneficial to the process of management of water utilization in the industry. The water-saving evaluation based on this is authentic and can serve the decision-making, thus achieving the purpose of strong supervision.
Key words: the steel industry; strong supervision; the process of water utilization; visualization; water saving evaluation；knowledge graph
