The Bessemer Process. The Bessemer process was the first inexpensive industrial process for the mass-production of steel from molten pig iron. The process is named after its inventor, Henry Bessemer, who took out a patent on the process in 1855. ... This process was refined in the 1700s with the introduction of Benjamin Huntsman's …

Steel Making Process. Steel is an alloy of iron usually containing less than 1.5% carbon. Steel can be cast into bars, strips, sheets, nails, spikes, wire, rods or pipes as needed by the intended user. Steel making process at an integrated steel plant involves three basic steps. First, the heat source used to melt iron ore is produced.
