The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel. The electric arc furnace melts recycled steel ...

Steel is produced from molten iron and from scrap iron and steel. There are three main methods of making steel. In each process, the iron, steel scrap, and other materials are placed in a furnace. While being heated, reactions remove excess carbon and unwanted substances from the iron and scrap. Other desired materials are then added.

Rolling changes the structure of the material. By rolling it in the right way, we make extremely strong steel for cars, or thin and light steel for tins. After rolling, we apply a thin layer of tin, paint, zinc or plastic coating, depending on the purpose. Then we package it before it goes to the customer.

Bessemer process, the first method discovered for mass-producing steel. Though named after Sir Henry Bessemer of England, the process evolved from the contributions of many investigators before it could be used on a broad commercial basis. It was apparently conceived independently and almost concurrently by Bessemer and by William Kelly of …

Steel was still unproven as a structural metal and production was slow and costly. That was until 1856 when Henry Bessemer came up with a more effective way to introduce oxygen into molten iron to reduce the carbon content. Now known as the Bessemer Process, Bessemer designed a pear-shaped receptacle—referred to as a …

A Short History of Steel. By Terence Bell. Blister steel production advanced in the 1740s when English clockmaker Benjamin Huntsman while trying to develop high-quality steel for his clock springs, found that the metal could be melted in clay crucibles and refined with a special flux to remove slag that the cementation process left behind.

Every ton of steel produced in 2018 emitted on average 1.85 tons of carbon dioxide, equating to about 8 percent of global carbon dioxide emissions. 2 Consequently, steel players across the globe, and especially in Europe, are increasingly facing a decarbonization challenge. This challenge is driven by three key developments that go …
