On the basis of the record of 818 heats created in April, a new breakthrough has been achieved again![/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]In order to achieve the steelmaking production organization capacity matching with the high-efficiency production rhythm, the steelmaking system takes reducing auxiliary time as the breakthrough point to improve the smelting rhythm. The life of tapping hole of domestic converter is mostly in 300-400 heats. Frequent replacement of tapping hole will greatly affect the production rhythm and reduce smelting efficiency.

In view of this situation, a company set up a tapping hole service life project research team, in-depth analysis and summary of production data, combined scientific research with practical operation.

1006 heats! The tap life of No.3 converter in Tangshan Iron and Steel Co. has reached the highest record in China!

 

  1. Research and develop the production process to prolong the life of tapping hole of split assembled converter
  2. Optimize the composition of filling materials
  3. Improve the pouring equipment and the corresponding size of tapping hole

Improvement of tap hole sleeve brick

  1. High temperature corrosion resistance
  2. High temperature compressive strength
  3. Antioxidant capacity

1006 heats! The tap life of No.3 converter in Tangshan Iron and Steel Co. has reached the highest record in China!

 

The reformed tapping hole of converter has excellent thermal shock stability and resistance to molten steel erosion. The utilization rate is increased by 2.3 times, which greatly improves the production efficiency and reduces the production cost.
