Kasutasavi Januari 13, In the decades before the Civil War steel was produced in great quantities. But the quality of it often varied widely. And with large machines, such as steam locomotives, and large structures, such as suspension bridges, being planned and built, it was necessary to manufacture steel that would perform as expected.
The new method of producing reliable steel revolutionized the steel industry and made widespread advances possible in railroads, bridge-building, construction, and shipbuilding.
The British inventor of the greatly improved steel process was Henry Bessemer, who was born in Charlton, England, on January 19, Bessemer's father operated a type foundry, which made mechanical type used in printing presses. He had devised a method of hardening the metal he used, which made his type last longer than type made by his competitors. Growing up around the type foundry, young Bessemer became interested in building things of metal and in coming up with his own inventions.
When he was 21 years old, he devised a stamping machine which would be useful to the British government, which routinely stamped important legal documents. The government praised his innovation, yet, in a bitter episode, it refused to pay him for his idea. Embittered by the experience with the stamping machine, Bessemer became very secretive about his further inventions.
He came up with a method for manufacturing gold paint to be used for decorative items such as picture frames. He kept his methods so secret that outsiders were never allowed to see the machines used to add metal chips to the paint. In the s, during the Crimean War , Bessemer became interested in solving a major problem for the British military. It was possible to produce more accurate cannons by rifling the bores, which meant cutting groves in the cannon barrel so the projectiles would rotate as they exited.
The problem with rifling the cannons commonly used was that they were made of iron, or of low quality steel, and the barrels could explode if the rifling created weaknesses. The solution, Bessemer reasoned, would create steel of such high quality that it could reliably be used to make rifled cannons.
