The chemistry of steelmaking The big picture

The main stages The main steps in making steel are shown on the left You can find more information about each step by clicking on it In this section we ll summarise the chemistry that is important in changing iron ore into steel

The Different Types of Steel and How They are Made

The most primitive technique for making steel was to melt down and combine wrought iron and cast iron However the amount of iron needed to produce this steel by product and the cost of providing these ingredients was so great that steel was hard to obtain and only available to the wealthy Additional costs also lay in the smelting process

process of making steel from iron ore

This page looks at the use of the Blast Furnace in the extraction of iron from iron ore and the conversion of the raw iron from the furnace into various kinds of steel Get More Info How steel pipe is made manufacture making

KOBELCO Pelletizing Process

KOBELCO Pelletizing Process Kobe Steel s history of pelletizing plants began when Pellets are made from iron ore that is finer than that used for sintered ore

Steel Making Steelmaking is the second step

• Steelmaking is the second step in producing steel from iron ore • In this stage impurities such as sulfur phosphorus and excess carbon are removed from the raw iron and alloying elements such as manganese nickel chromium and vanadium are added to produce the exact steel required

Different Types of Iron Ore Processing

For steel making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore this is the so called Bessemer limit A Bessemer ore carrying 52% of iron must not have more than 052% of phosphorus and the sulphur should not exceed 04% But since the presence of phosphorus in pig iron increases the fluidity

Iron and Steel Open University

The key step in smelting iron ore to make raw metal is providing a reducing agent as well as heat a reducing agent is a chemical that reacts with the iron oxides in the ore to release the iron in metallic form The simplicity of charcoal is that it acts as both the heat source and the reducing agent
