IRON MAKING,STEEL MAKING AND STEEL ROLLING TECHNOLOGIES

What would it take for civilization on Earth to collapse in an instant? A nuclear explosion? A raging and incurable worldwide epidemic? A surprise black hole capable of swallowing the sun? Possibly. Yet, what if something seemingly less catastrophic forced civilization to an end? What if steel became nonexistent? The effects wouldn’t seem to be as cataclysmic as the disappearance of the sun; still, we would suffer devastating corollaries if steel was absent from our planet. Civilization would collapse—and not just literally.

Steel is influential in more aspects of our lives than we are aware of. This material is used across the globe for a variety of purposes due to its functionality, adaptability, machinability and strength. Mankind would not exist successfully today if it weren’t for the development of steel. Steel is an instrumental material in the international progression of infrastructure, economy, transportation, sustainability, health and entertainment. In looking at these necessary components of civilization, we offer a list of six reasons, in a three-part blog series, to explain why society would collapse without the world’s most common alloy.

Steel is the material that makes infrastructure, construction and transportation possible. Without steel, we’d have no skyscrapers to work in, no cars to get us there and no planes to fly around in. Take a look at reasons one and two in our list of why life would fall apart without such a material.

Steel is made through following route:

1. Iron Making

2. Steel Making

Steel is further casted in the form of billets,blooms,ingots and slab form and rolled further to form following:

1. Long Products : Angles,Channels,Beams,Rails,Rebars,Wire rods

2. Flat Products : Plates,sheets & strips

ALL ABOUT AGGLOMERATION - 1

Iron found in the nature are not in the form of lumps always and due to depletion of mines(Run of Mines) as of now, fines are costing around 90 % of total ore mining. Since fines are not suitable for Blast furnaces due to its size hence fines are agglomerated to meet the standard size for making it suitable to charge in the blast furnaces.
Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical properties of the ingredients. The purpose of sinter are to be used converting iron into steel.
