Another way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter.
This was the puddling process, in which molten cast iron is stirred with rods, thus rapidly burning away the carbon. 17 Yet even the puddling process lacked the efficiency to make steel an economic alternative to cast iron…
Direct iron production at molten metal state from iron oxides by the sole application of electrical energy represents a possible route to decarbonize steel industry.
A hot stream of molten iron that is 420 kilometres wide is moving westwards under North America and Siberia and has inexplicably tripled its speed over the past 15 years
The reported pools of molten metal under the rubble must also have contained some of that molten steel, and perhaps molten iron from thermitic cutting charges as well. Figure 7. An excavator picks up metal rubble from deep within the pile, and some of it is dripping a yellow-white hot liquid metal at or above 1200°C/2200°F.
Molten ferrous metals are often handled in steel ladles with a refractory lining. It's only since about the 1860s that any ferrous metals other than cast iron (which has a significantly lower melting point than steel) were handled in a molten state in any sort of quantity.
More pig iron is added, the unwanted carbon combines with oxygen, the impurities are removed as slag and the iron turns to molten steel. Skilled workers sample the steel and continue the process until the iron has exactly the right carbon content to make a particular type of steel.
In a basic oxygen furnace, molten iron ore is the principal raw material and is mixed with varying quantities of steel scrap and alloys to produce different grades of steel. In an electric arc furnace, recycled steel scrap is melted directly into new steel. About 12% of our steel is made from recycled steel.
Castability. Most people haven't encountered iron or steel in their molten state—which is understandable, since iron melts at about 2300˚F and steel melts at 2600˚F, and both are poured into molds at even hotter temperatures.
Molten Metal Handling. Minteq offers the steel maker a complete systems solution for iron and steel ladles as well as vacuum degassing. We call this molten metal handling.
Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel.
Steel, alloy of iron and carbon in which the carbon content ranges up to 2 percent (with a higher carbon content, the material is defined as cast iron). By far the most widely used material for building the world’s infrastructure and industries, it is used to fabricate everything from sewing needles to oil tankers.
Molten Metal Workers Reported Molten Metal in Ground Zero Rubble Reports of molten metal in the foundations of the three World Trade Center skyscrapers are frequently noted in literature of proponents of theories that the buildings were destroyed through controlled demolition.
One of the earliest forms of steel, blister steel, began production in Germany and England in the 17th century and was produced by increasing the carbon content in molten pig iron using a process known as cementation. In this process, bars of wrought iron were layered with powdered charcoal in stone boxes and heated.

Steel is the world's most popular construction material because of its unique combination of durability, workability and cost. It's an iron alloy that contains 0.2-2 percent carbon by weight. According to the World Steel Association, some of the largest steel producing countries are China, Japan, US
12.5 Iron And Steel Production ... The molten iron and slag are removed, or cast, from the furnace periodically. The casting process begins with drilling a hole, called the taphole, into the clay-filled iron notch at the base of the hearth. During casting, molten iron flows into runners that lead to transport ladles. Slag also flows into the clay-filled iron notch at the base of the hearth ...

Steel is a refined form of Iron added by various mods. IndustrialCraft 2 adds Steel, but it is called Refined Iron. Making Steel requires either the Railcraft or IndustrialCraft Blast Furnace, the Bronze Plated Blast Furnace, the Industrial Blast Furnace, or the High Oven.
Molten Iron is a liquid material added by Tinkers' Construct that is created by smelting Iron Ingots or other Iron items from a Smeltery Controller. Molten Iron is one of the three types of molten material used in the creation of Molten Alumite. The following is a table of items that may be...
Direct iron production at molten metal state from iron oxides by the sole application of electrical energy represents a possible route to decarbonize steel industry. Although chemically simple, this reaction is difficult to implement due to the problem of the multiple valence states of iron and to
Steel. Most of the molten iron from a Blast Furnace is used to make one of a number of types of steel. There isn't just one substance called steel - they are a family of alloys of iron with carbon or various metals. More about this later . . . Steel-making: the basic oxygen process. Impurities in the iron from the Blast Furnace include carbon, sulphur, phosphorus and silicon. These have to be ...
