After cooling down, the crucibles contained what we now know as steel — an iron-carbon alloy. Read More: US Steel Costs Soar, Manufacturers Grapple With Shortages After the discovery of iron-carbon alloys, various civilizations began to scale up their steel-production practices, allowing them to make improved weapons, tools and structures.
1. Fill a heat-safe container with water or oil deep enough to submerge your steel. Use a coffee can or similarly shaped container as your quenching chamber. Pour in water or vegetable oil so it's 2–3 inches (5.1–7.6 cm) from the rim of the container. Make sure the oil or water is at room temperature.
Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using charcoal.
Steel edges were usually welded to a wrought iron core or blade to make a steeled tool in the most economical manner. Some History Broadly speaking, Europeans were devoted to the bloomery process until late in the Middle Ages, while the Chinese followed the opposite path, producing high-quality iron castings from the Chou Dynasty onward.

How to make steel. At the most basic, steel is made by mixing carbon and iron at very high temperatures (above 2600°F). Primary steelmaking creates steel from a product called "pig iron.". Pig iron is smelted iron, from ore, which contains more carbon than is correct for steel…

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.The heat of oxidation raises the temperature and keeps the iron molten. As the air passes through the molten pig iron, impurities unite with the oxygen to form oxides.
Making steel. At Scunthorpe, we use the Basic Oxygen Steelmaking (BOS) process – our modern convertors (or vessels) take a combined charge of scrap and liquid iron of up to 330 tonnes and convert this into steel in just 25 minutes. When the liquid iron arrives at the BOS Plant, it's poured from the torpedoes into refractory-lined charging ...

We make steel From raw material to finished product – our business extends globally from iron ore and coal mining to a wide range of steel products and services. In 2014 we mined 63.9 million tonnes of iron ore and 7 million tonnes of coking coal, overall we produced 93.1 million tonnes of crude steel.
Steelmaking has played a crucial role in the development of ancient, medieval, and modern technological societies. Early processes of steel making were made during the classical era in Ancient Iran, Ancient China, India, and Rome.. Cast iron is a hard, brittle material that is difficult to work, whereas steel is malleable, relatively easily formed and a versatile material.
