STAVE

Real-time repairable blast furnace stave

The present invention relates to a stave and to the structure inside a blast furnace that produces molten iron while charging coke and iron ore.  

If the cooling pipe of the stave is damaged due to the inevitable shock inside the blast furnace, and the stave cooling pipe is damaged, it must be repaired immediately. However, due to the high pressure and high temperature environment inside the blast furnace, it is difficult to repair the stave without stopping the blast furnace, so manufacturing costs increase as the operation of the blast furnace is stopped to repair the stave. This technology seeks to propose a stave that can automatically repair damaged cooling pipes without stopping the operation of the blast furnace.

This technology repairs damaged parts of cooling pipes in real time, allowing staves to be repaired without stopping the operation of the blast furnace, thereby minimizing economic losses and contributing to the safety and lifespan of the blast furnace, thereby improving productivity in the steel industry.

Key Features:

• The stave consists of a cooling housing and a cooling pipe through which coolant containing an epoxy material flows
• It includes a maintenance pipe through which a repair liquid containing an epoxy hardener flows, and the outlet is located adjacent to the cooling pipe
• Further includes a fixing plate for fixing the cooling pipe, and the cooling housing has a first through-hole at a position corresponding to the fixing plate
• It has a second through-hole at a position not overlapping with the fixing plate, The water pipe penetrates the second through hole
