Abstract:In ultra fast cooling equipment, water supply pipeline is an important part. Water supply pipeline arrangement is related to the ultra fast cooling heat exchanging efficiency of the equipment, the cooling uniformity and the cost of equipment. In order to solve the problem of uneven water supply pipeline of water supply and ultra fast cooling equipment, the ANSYS Fluent software was applied for numerical simulation of the flow in the water supply pipe line. In designing of the pipeline for a steelmaking plant, designers proposed four different pipeline design schemes. Through the application of ANSYS Fluent computing speed and pressure contour four schemes of pipeline flow, the pipeline optimal design solution was ultimately determined.
