Long Campaign of BF with Overheating-Free Cooling Stave

A basic idea of permanent lining in designing long campaign of BF was put forward. BF designer should follow a chain of thinking procedure: Cooling water-Cooling system-Refractory lining. The temperature field of BF wall and cooling stave was calculated using heat transfer model and the results were proved by a 1 000-1 200 ℃ test rig. The overheating-free cooling stave with different parameters was designed, and such a long campaign of BF (15 years) was going to put into construction.
