Holding Pit + Reheating Furnace->100% HOT LOADING RHF


This project adopts a combined mode of one set of holding pits + one heating furnace by adding holding pits, replacing the original design with two heating furnaces.

The original project was configured with two continuous casting lines matching two rolling lines, both of which adopted the cold billet charging mode for production.Based on the actual site conditions, capacity matching and other factors, the production line renovation is carried out as follows:

Reduce one heating furnace and realize 100% hot loading by RHF of billets to minimize billet heat loss.

Add a new set of holding pits for the heat preservation of surplus billets, so as to adjust the production rhythm of hot-charged billets for the heating furnace.

The combined mode of holding pits + heating furnace meets the designed production capacity of the original rolling lines.

After renovation, 

the total project investment is reduced, 

gas consumption is greatly decreased, 

the heating furnace capacity and equipment utilization rate are significantly improved, 

and the production cost per ton of steel is substantially reduced.
