Abstract

High-pressure water descaling is an important equipment in hot rolling of steel plant. Filling post pipelines of descaling valve during the interval of descaling operation can effectively protect the system equipment. Pipeline filling can prevent water loss from becoming empty pipe and forming air collection, thus to eliminate pipeline impact and vibration caused by descaling operation, and to avoid damage of pipeline equipment. There are two methods of water filling: low-pressure filling and high-pressure filling. Non-energy-saving descaling system, i.e. the system of mixed water supply of descaling pump and accumulator, and the descaling system of direct water supply of descaling pump, should choose high-pressure filling, which consumes little energy of good reliability and safety; while the energy-saving descaling system, i.e. the system of mixed water supply of descaling pump and accumulator, should choose low-pressure filling, which has lower energy consumption and remarkable energy-saving effect, but with relatively poor system safety.
