近年来高炉汽化冷却虽然在我国取得了一定的成效,但是如何建立稳定的水循环和更有效地延长冷却设备的寿命,仍需进一步探讨.而这个问题的实质就是汽化冷却的结构设计问题. 一、高炉汽化冷却的整体结构形式目前我国中型以上高炉有的从炉底到炉身全炉采用汽化冷却,有的只在炉腹和炉身采用汽化冷却;结构形式也不一致,首钢和
In recent years, although the blast furnace gasification and cooling has achieved some success in our country, how to establish a stable water cycle and extend the life of the cooling equipment more effectively still need to be further explored.And the essence of this issue is the structural design of vaporization and cooling.First, The overall structure of the blast furnace gasification cooling At present, some medium-sized blast furnace in our country from the bottom to the shaft of the furnace using evaporative cooling, and some only in the bosh and the furnace using evaporative cooling; structure is inconsistent, Shougang and
