高炉软水密闭循环冷却系统若干问题的探讨

作者针对高炉软水密闭循环冷却系统存在的几个可讨论性问题提出了如下观点：冷却介质采用软水或纯水都是可靠的；建议新建高炉的供、回水总管采用架空单路总管；为应付事故断电，仅设双路电源和柴油机水泵是可靠的；在不预留转入汽化冷却的情况下膨胀罐可设在地面，只要系统中配备了膨胀罐或头部罐，就不必再设脱气罐。

Discussion on several problems of closed loop soft water cooling system for BF

The author puts forward the following opinions on several discussible problems of closed loop soft water cooling system for blast:furnace.It is reliable to use either soft water or pure water as cooling medium;it is recommended to install the main supply and back water pipes for new blast furnace by overhead monopipe laying ;the installation of double loop power supply and standby diesel pump are enough for meeting accident power failure;it is possible to install the expansion tank on ground without evaporative cooling; there is no necessity to install degassing tank if the expansion tank or head tank had been provided in the loop.
