Abstract:The offline baking steel ladle intelligent management system established in this paper uses Springboot+Vue to build the system framework, and realizes database data transmission through http protocol, OPC protocol and Mybatis-Plus middleware. It intelligently captures or calculates the variable parameters required for offline steel baking ladle calculation that are difficult to collect or define, and substitutes them into the calculation method of offline baking steel ladle quantity written at the back-end of the system. So the intelligent application of the offline baking steel ladle quantity calculation model in actual production is realized. Through the intelligent operation of the system, the problems that the offline baking steel ladle quantity calculation model is only described in the article and cannot be applied in practice are solved, such as the difficulty of manual understanding of variable parameters in the calculation model, the lack of description and inaccuracy of parameter collection methods, and the difficulty of data collection. Through accurate intelligent management of offline baking steel ladle, the production operation and time cost can be reduced, unreasonable gas consumption can be reduced, the production and operation efficiency of steel plant can be improved, and the digital and intelligent level of steelmaking production can be further improved. In the process of practical application, the system has calculated that the theoretical number of offline baking steel ladle in a steel plant was 4 and the current number of offline baking steel ladle was 8. It was recommended to decrease the number of 4 offline baking steel ladles, which was recommended that the number of offline baking steel ladle in the steel plant of the example should be reduced from 8 to 4 every 72 hours. This can reduce gas consumption by approximately 3.85 million m3 throughout the year and save production costs by 5.01 million yuan. In addition，The system fills the gap in China’s lack of systematic control over offline baking of steel ladle, and has important practical value under the theme of “green” production in the national “14th Five Year Plan”.
