The invention of the Bessemer Convertor in 1856 enabled the great increase in steel production of the late 1800s. Andrew Carnegie saw their potential on a trip to Sheffield, England built mills to use them in the United States. The Bessemer Convertor can take the output directly from a blast furnace and turn it into steel. As the iron goes from the blast furnace to the converter, other metals are thrown into the iron depending on the type of steel desired. Air is forced into the bottom of the convertor. It burns excess carbon out of the iron turning it into steel. Then the Bessemer Convertor is rolled over and the steel is poured into carts and taken to the next step. Previously Steel had been difficult to make and had been used for very few items. The Romans used it for swords but used iron for most utensils. Iron rails in rail road tracks could be replaced with steel rails and trains could double or triple in speed. After a number of years, Carnegie sold his company and it became U.S. Steel. He created a charitable foundation with the money he got from the sale of his company. That foundation created much of the public library system in the United States. It created an entertainment building in New York called Carnegie Hall. And it financed a study that led to a book by Gunnar Myrdal, called, An American Dilemma. That book provided the intellectual basis for the Civil Rights Movement.
The new technique for making steel was called the Bessemer process. It involved blowing air through molten pig iron to remove impurities and create a stronger, more durable steel product.
Normalized killed steel forging is a process where the steel alloy is first heated to a critical temperature, then cooled in still air or a controlled environment to create a uniform grain structure. This process improves the mechanical properties of the steel, making it stronger and more ductile. Killed steel refers to steel that has been deoxidized to improve its properties, such as resistance to corrosion or heat.
Steel was strong and more lightweight than stone.
The process of transforming iron into steel is called "steelmaking" or "steel production." It involves removing impurities from iron and adjusting the carbon content to create the desired properties in the steel.
The process by which steel is covered with zinc is called galvanization. This helps to protect the steel from corrosion and extends its lifespan.

It is a steel making stage in whice steel refined and different elements are added in it.
That would be Henry Bessemer, inventor of the Bessemer Converter which allowed the processing of Steel on an industrial scale. The process involves the removal of impurities (an important factor in Steel manufacture) through oxidation.

the bessemer process and the open-heart process(:
Oxygen is used in steel making to react with carbon in the molten iron to remove impurities like carbon, sulfur, and phosphorus. This process helps in achieving the desired carbon content and composition of the steel, resulting in a higher quality end product with improved strength and properties. Additionally, using oxygen instead of air allows for better control over the chemical reactions and reduces the time and energy required for the steelmaking process.
