Outline
The hourly output and output per shift of pickling line tandem cold mill are influenced by such factors as varieties, specifications and production transition processes of products as well as the differences are significant. Currently, the evaluation of production efficiency is carried out by adopting the mode of converting into output or coil quantity for most mills, which is with such limitations as single evaluative dimension and insufficient objectivity of results. In the paper, the existing production specifications are divided into 16 class intervals combining with the actual productions of pickling line tandem cold mill and objectives of productions are set based on the characteristics of each class interval aiming at the problem. The quantitative evaluation system of monthly production efficiency and efficiency of each shift or group is established through the two core indicators, hourly coil quantity and rate of reaching the standard. Practices show that the multidimensional production efficiency evaluation could be realized with this system, which could provide the evaluation basis for optimizing production efficiency of shift and group as well as be with value of extensive promotion.
