| Abstract: | Entire cooling thin lining structure is used for the overhaul of No.7 blast furnace in 2004,and lot of tuyere breakage is found after it put into use.The average annual burning loss is 150 from 2005 to 2009.The main reason for it are quality fluctuation of fuel and raw material,unreasonable design of cooling system,high load of charged alkali metal,zinc,inadaptation of top and bottom adjustment,stiff furnace operation,hearth heap-up and etc.The counter measurements to reduce the burning loss of tuyere are carried out,such as： improving the charged raw material,adjusting the layout of tuyere,optimizing the material distribution and furnace profile.And great economic benefit is achieved at the same time. |
