摘要
方坯连铸二次喷淋冷却用水量不稳定、压力波动大,导致设备损坏,改用回流装置调节压力浪费了大量富余水量的输送能耗,为此提出采用高压变频器根据水量需求进行控制,从而做到节能。改造实践证明:结合工艺控制需求,采用完美无谐波高压变频器对二次喷淋供水泵实施调速节能控制,系统稳定,调节及时,且节省了大量的电能,具有较好的经济与社会效益。
The amount of water and the pressure used in secondary spray cooling of billet conticaster varies greatly.To pump the large amount of water that flows back through backflow devices wastes a lot of energy.Therefore,high voltage inverter is proposed to regulate the water pressure according to process demand.Practice shows that the usage of perfect non harmonic high voltage inverter to adjust the speed of the water pump can be rather stable and timely,and that a great deal of energy can be saved.Good technological and economical benefits can be gained.
