  Man has the ability to utilize natural resources for his benefit. This ability gave him an upper hand over other animals and he gradually took over the charge. As science and technology made progress and new and innovative ideas started making dreams a reality, search for suitable engineering materials gained pace. Metals took the charge from wood and stones. The modern era has seen the

While in industry, we use a lot of energy obtained from various sources to help in varied activities. Fuels play an important role here. We have a lot of choices also: traditional fuels such as Fossil Fuels, Bio-Fuels (animal excrete and agricultural waste) and modern atomic fuels. It seems quite obvious that we don't use atomic fuels in industries. So, the most important question arises:

This post comes after almost a year! It was really a long time....   Today I'll talk of the dull steel and the shiny steel. After operating for almost 90 years and producing different types of steel for various segments, Tata Steel decided to go for cold rolling mill. When I joined this team in 1999, our general conception of steel was dark-dull metal which was being produced. When we started

Steel is a metal on which, various operations can be performed to make something useful out of it. In this post, I'll touch some of them.1. Cutting: Solid metal is cut into different shapes either by a mechanical cutter or energy source. The basic operations of cutting a metal piece by hand (saw) or by machining (cutting saw, lathe, milling machine, planer machine etc) or by energy source such as

What comes to your mind when I say "coke"? Well, Its not your usual drink! Its is a form of coal that is used in the blast furnaces as a reducing agent.Coal is a fossil fuel that is found in abundance in the nature. Most of them are found underground and require sophisticated mining skills to take them out.There are three basic qualities that characterises the coal:1. Heat generated2. Ash

For the purpose of extracting iron from its ore, blast furnace is the most important setup. In todays post, I'll talk about the basics of a blast furnace.Blast furnace is a big structure where iron ore is melted to extract the iron.Now, we have certain points in this statement.1. The furnace is a big structure.2. Iron ore goes in.3. Ore is heated.4. Molten iron is collected.Now, we can figure out

Earth's crust has lots of magical elements in it. The key lies in its finding and extraction. When we talk of Iron Ore, let us us talk of two more words: abundance and commercial mining.What is abundance?Well, as the word suggests, it is the amount of ore that is present in a particular area.What is commercial mining? How does it relate to abundance?Again, commercial mining is the deployment of

Iron extraction in ancient times can be traced to ancient egypt and india about 5000 to 7000 years back. Although very crude methods were used to get the metal, the entire process was under strict vigil so as to maintain the seceracy of the process. The high impact weapons that came out from the forge and foundry shops were high in demand and the artisans, well-respected!In ancient egypt, the

When I was very young, the term STEEL gave the image of shiny polished grey metal. In the high school, we came to know that Iron (Fe) came from inside the earth's crust in raw forms called ores. Specialized methods were used to take out the pure metal to make it useful.All this information had no practical implications till I came into the real world of steel. Many a times, things seem to be
