Modern methods, however, are still based the same premise as the Bessemer Process, namely, how to most efficiently use oxygen to lower the carbon content in iron. Modern steelmaking can be broken down into six steps: 1. Ironmaking: In the first step, the raw inputs iron ore, coke, and lime are melted in a blast furnace. The resulting molten iron - also referred to as ''hot metal'' - still

Tapping temperatures are in the range 1,400° to 1,500° C (2,550° to 2,700° F); to save energy, the hot
Steel Ingot | Feed The Beast Wiki | Fandom
Steel Ingots are produced by the Blast Furnace from one Iron Ingot and either one Coal Coke or four Charcoal.Alternatively, one can use Industrial Blast Furnace (one refined iron and two coal dust) when GregTech is installed. They are used in a nuer of RailCraft recipes, most notably the H.S. Rail and the Bore Head, and, indirectly, the Tunnel Bore via the production of Steel Blocks.

Iron Ore Smelting Process - Bright Hub Engineering
Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter. Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron.
