There are different kinds of lance pipes used for each steel-making process. Also, the lance pipes mainly used for Blast Furnace (BF) and Electric Furnace (EF) would be various as well. 
Customers will consider and want to know which kind of lance pipe is suitable for each stage of the steel production for better performance and effectiveness. Some users do not know what kind of lance pipe is available for each process.

In this blog, we will introduce lance pipe variation suitable for each process stage of the steel making so that customers would know the most suitable one for their demands and manage the better purchasing plan.


Lance pipes for Blast Furnace Steel-making Process

There are lots of process in steel production by Blast Furnace (BF). Below are some main processes that would use lance pipes as materials to support the production.

  • SC Lance and TH Lance:  
    • Tapping At Pig Iron:

    • Cleaning Laddle Furnace: after a long time using for steel making process, the leftover of hard steel somehow stick on the wall of Laddle Furnace. Using SC lance in this process to melt down those parts would be needed. SC is suitable to use without occurring any damages to the Furnace's wall.
      TH Lance will be used for the position of steel melting flow hole after longtime using sticking.

Lance Pipes for Electric Furnace steel-making process

There are lots of processes in steel production by Electric Furnace including Electric Arc Furnace and Induction Furnace. Below are some main processes that lance pipes would be used as materials to support the production.

  • Thermic Lance: Cutting Scrap at scrapyard as preparation for Steel production process as inputs materials.

Conclusion

For each step in the production of steel, a certain type of lance pipe is required. Lance pipes, which are mostly utilized for BF and EAF, would also change. Customers will think about and ask what sort of lance pipe is best for each step of the steel manufacturing in order to get better results. Some consumers may not aware the types of lance pipes that are accessible for each operation.
