Steel which is an alloy of iron and carbon contains less than 2% carbon and 1% Manganese. Steel also comprises small amounts of Silicon Phosphorus Sulphur and oxygen. From our cars refrigerators and washing machine till cargo ships and surgical scalpels everything requires steel.
Steel is produced mainly in two ways. There are two main routes for making steel: the Blast Furnace Basic Oxygen Furnace Route and the electric arc root. The type of raw materials consumed for the manufacturing of the Steel in two different ways vary. The components which are commonly used for the steel manufactured by the BF-BOF route are iron ore, coal, and recycled steel. In the other procedure i.e. EAF, recycled steel is used along with electricity for the production of steel. Almost 70% of the Steelers produced using the black furnace basic oxygen furnace procedure. In this procedure, the ores are reduced to iron which is also called heat metal or pig iron. Then the iron is converted into Steel in the BOF. The Steel lesson cast and rolled and delivered as coil plate sections and bars.
The Steel which is made using the EAF procedure uses electricity to melt the recycled Steel. Various alloys are also added for adding to the required components and matching the chemical composition.
Steel products remain in use for decades before they are needed to be recycled. Hence recycled Steel is not enough to meet the growing demand for Steel. Hans most of the Steel contains recycled steel scrap as an input.
Various kinds of Steels based on different physical, chemical, and environmental properties. There are more than 3500 different grades of Steel present in the market today. There are 4 broad categories of Steel. These are carbon steel, tool steel, stainless steel, and alloy Steel. The majority of the steel produced is carbon Steel. Tools Steels are used only for developing various machine parts and tools. Most of the common household items consist of stainless steel which is composed of 10-20% chromium which offers corrosion resistance. Alloy Steel consists of various components such as iron, carbon, and other elements such as vanadium Silicon Nickel manganese Copper and chromium. 20 years have seen the development of 70% of modern Steel. Modern Steels are 35% lighter than the Steels which used to be used in the past. The world crude steel production has reached 1808.6 million tonnes in 2018.
Steel provides great durability as compared to any other materials. This is totally recyclable and requires relatively low amounts of energy to be produced. Lightweight Steel is very helpful for saving energy as well as resources. Cell steel is recyclable. It is environment-friendly as well as sustainable. The steel industry has taken a lot of effort in the past decade for the reduction of dust and emissions. The steel industry has successfully modernised the procedures of producing Steel in the past couple of years that it requires only 40% of the energy for the production as compared to the past. Is recycled. It is very easy to recycle Steel as the recovery of Steel from the waste is very easy because of its unique magnetic properties.
Steel is a very widely used manufacturing product because of office various Straits such as strength and durability. The key trait of steel is its sustainability. Hence, steel is widely used around the globe for various manufacturing purposes. Still doesn’t lose its unique properties irrespective of the number of times it undergoes the recycling process. Steel is one of the most valuable resources in the world because of its strength, sustainability, and versatility. It is used in countless industries such as the construction of buildings, stadiums, and bridges to automobiles, pipelines, farm equipment, and tools.
