- The Flowchart Of The Processing Of Iron And Steel
Types of iron and steel. Cast iron has already been mentioned above. This section deals with the types of iron and steel which are produced as a result of the steel-making process. Wrought iron. If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron. Wrought iron is quite soft and easily worked and has ...

The converter in the BOS Plant turns the pig iron into steel. Here, we add oxygen and used steel, or steel scrap. Scrap ensures that the temperature in the converter does not rise too high and it is sustainable: empty tins, old cars, refrigerators and even bridges are reused. Steel is a pre-eminently circular product: it can be endlessly reused.

Steel production is a 24-hour-a-day, 365-day-a-year process, dependent on a consistent supply of raw materials and huge amounts of energy. According to the World Steel Association, world crude steel production has increased from 851 million tonnes (Mt) in 2001 to 1,606 Mt in 2013 and world average steel use per capita has steadily …

World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

With this in mind, here are the 6 steps to modern steel production explained. Step 1 – The iron making process. As iron is the main component of steel it firstly needs to be made. Iron ore, lime, and coke are placed into a blast furnace and melted. The resulting liquid known as molten iron is then formed.

The blast furnace and direct reduction processes have been the major iron production routes for various iron ores (i.e. goethite, hematite, magnetite, maghemite, siderite, etc.) in the past few decades, but the challenges of maintaining the iron and steel-making processes are enormous. The challenges, such as cumbersome production …

The steel production process is a multi-faceted journey that begins with extracting and processing iron ore, a primary raw material essential to steel making. Iron ore undergoes a series of refining steps to extract the iron content, culminating in the creation of molten iron. This molten iron is then subjected to steel melting, a critical ...
