Iron ore is found in nature as rocks. During the industrial process, the blending of this iron ore occurs with different components. By using different mechanical procedures and the latest innovation, iron ore is handled and after that sold to steel companies.
What Are Iron Ore Pellets?
When iron ore fines undergo the process of pelletization they produce iron ore pellets which are of uniformly size. During pelletization, the iron ore fines are mixed with certain additives such as bentonite and are then converted into oval lumps using a pelletizer. The balls undergo the hardening process by firing them with fuel. These pellets of iron metal are essential in the creation of steel. There are several pelletizing processes available currently but Straight Traveling Grate (STG) and Grate Kiln (GK) process are the most popular ones.
Uses of Iron Ore Pellets In Blast Furnace
Iron ore pellet can act as a substitute to sinter and calibrate lump ore in blast furnace because of the following properties:
- Due to high porosity in pellets, the reduction process is quicker.
- The pellets have a spherical shape with open pores. This offers a greater permeability and results in easy furnace operations.
- It is the high pellet strength that offers a greater resistance when it comes to disintegration during the descent of burden.
- The cold crushing strength of pellets is exorbitantly high therefore the production of fines in a stock house is almost negligible.
- In comparison to calibrated lump ore, pellets have a uniform chemical composition. LOI absence is another valuable standpoint of the pellets.
An EndNote
The pellets play a pivotal role in the creation of steel. Different extensions, transport vehicles, and family unit apparatuses use steel during production
