We can list many Advantages of using HBI as a substitution of Scrap, which these are some of them:
- The lower price of HBI than scrap or raw iron
- Better charge of HBI
- Easier loading due to the compression of HBI compare to the Scrap
- Reduction of energy consumption per time unit when using briquettes instead of scrap
- Easier transportation and movement
- Resistance to the weather conditions
- Having density, more than sponge iron for two times.
- Having very few remaining elements in the melt
- Reduction of the number of charges to the furnace
- Possibility of ceaseless charge to the furnace
- Possibility of controlling nitrogen in steel
- Creating stability in steel melting
- Having specific chemical and physical analysis
- Using of HBI can be based on up to 30% replacement of scrap (15% light scrap and 15% heavy Scrap) by basket charge and more than that, up to 60% by continuous charge (total 90%). In fact, only up to 30% of the charge of HBI can be carried out by the basket for the following reasons:
- Preventing HBI agglomerating at the bottom of the furnace
- Avoiding mixing HBI and lubricants at the bottom of the furnace
- The ability to mix HBI and scrap in the charge basket of materials to the furnace
