Pulverized coal utilization in the blast furnace is decided by the particle flow and combustion behaviors in the raceway.Under a specific operating condition,these behaviors are directly related to the lance configura...
The zinc vapor condenses on the top of the blast furnace and adheres to the furnace wall, causing the furnace wall to thicken and nodulate, which affects the smooth operation of the furnace. It can block up the gas up...
Functional properties of biological surfaces have gained increasing interest in the last two decades,especially with regard to wetting and sei-cleaning.Here,biological surfaces of arthropods(Collembola)and plants(sacr...

The interaction mechanism between the combustion products of pulverized coal injected and coke in the raceway of blast furnace was studied through thermodynamic calculation and experiments.The results indicated that a...
This article presents in detail the assembling and welding process technique of the steel box girder tuyere blocks of Taizhou Bridge. The application of this process technique effectively solves the problem of welding...
Tuyere coke probing was conducted at the Baosteel Corex Plant in order to gain a better understanding of the structure of the char bed in the melter gasifier ( MG ). After screening, the specimens were observed by a...
