Abstract：Life cycle cost method was used to analysis the life cycle cost of one opening cooling water circulation system in Shougang Jingtang Iron and Steel Corporation. This model quantifies all kinds of costs in system operation and can produce optimized concentration rates by modifying parameters based on practical situations of different seasons. Therefore, it can be used as guideline for the optimization of designing, operation and improvement of opening cooling water circulation system.
