Bessemer Project
The Age of Iron to the Age of Steel
A new technological advancement and invention.
made new inventions and innovations possible
Steel making
Created in England by Henry Bessemer in 1855
used a converter and a blast of air in a de-carbonization process to create the steel from iron
summary and definition
steel making method by blasting air through hot iron to burn out extra carbon and impurities.
It lowered the cost of steel production
history of steel and iron
steel is an alloy of iron with carbon
steel used to be produced in blast furnaces
William Kelly
experimented on how to convert iron to steel
figured out that you could refine fluid iron by passing air through it
Henry Bessemer
He registered more than 110 patents
People of London elected him and two years later he was knighted
The Converter
A large pear shaped receptacle
filled with molten pig iron
The Phosphorus Problem
The Bessemer process didn't remove phosphorus from pig iron
could only be used on pig iron from phosphorus free ores.
Sidney Gilchrist Thomas
adding limestone to the converter drew the phosphorus from the pig iron
This method resulted in phosphorus free steel which is called the Basic Bessemer Process
impact of Bessemer Process
massive stores of iron ore from all over the world could be used to make pig iron for Bessemer converters
led to inventions and innovations of the second industrial revolution
