How does the bessemer steel process work

In fact, it is the process that may have single-handedly allowed for the industrial revolution. The Bessemer Process was the first inexpensive industrial process that allowed for the mass production of steel. Before the development of an open-mouth furnace, the process used a molten pig iron to melt iron. The real difference with this process was that air was forced through the molten iron to remove impurities.

Iron would be added to the molten pig and melted down to a bubbling point. By blowing oxygen in with the molten iron, any impurities would oxidize and separate.

These impurities include silicon, manganese and carbon which would then escape the pig iron as a gas or solidify into a slag. Slag simply means by-product left over after a metal has been separated from the ore.

Since steel is smelted from iron, these impurities are what is separated in the iron to unveil pure steel for production use. He was an English man born in The first patent for the process was taken out in There are some controversial arguments that a different man invented the process.

A William Kelly of the United States did patent the same type of discovery but the date was a few years after Bessemer. Today, Sir Henry Bessemer is still widely accepted as the inventor and first inventor of the process. There are very few things in history that you can genuinely say changed the world. The Bessemer Process is one of them. The biggest way that the Bessemer Process changed the world was by making steel cost-effective and mass-producible.

Steel became a dominant construction material solely because of this invention. Once steel became cheaper and easy to mass-produce, stronger rails for railroads were able to be built. The United States, among other countries, could lay railways like never before.

The growth of railroads during the 19th century in both Europe and America put pressure on the iron industry to produce more, but the steel industry was still struggling with inefficient production processes.

This changed in when Henry Bessemer discovered a process that had an effective way to add oxygen to molten iron that reduced the carbon content. This was also the same year that Sabel Steel was founded. When oxygen passes through the molten metal, it would react with the carbon, releasing carbon dioxide and creating a purer iron. By weight, steel contains about 2.

Steel, for example, is both harder and stronger than pure iron. The definition for no. Individual pieces not over 60 x 24 inches charging box size prepared in a manner to insure compact charging, as specified by the Institute of Scrap Recycling Industries.

Typically, materials should stay within the 6 feet by 20 feet range. The main difference in 1 Iron and Unprepared 1 Iron is the length and width. This is suppose to include culverts but two steel mills we sell to and most yards will no longer accept culverts as 2 iron but as light iron due to the chemical make up of the metal.
