THE BLAST FURNACE

They have thick steel sides, lined with refractory bricks, to ensure that heat is not lost. Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. Get price

Bessemer Process for kids: Cheap Steel Production

In between wrought and cast iron is steel (with .2% to 1.5% carbon) making it harder than wrought iron, yet malleable and flexible, unlike cast iron. These properties make steel far more useful than either wrought or cast iron but there was no simple way to control the carbon level in iron so that steel could be manufactured cheaply and efficiently in large quantities.

IRON AND STEEL

2020/8/29Mild steel Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things - nails Get price

What Is Stainless Steel?

"Stainless" steel is actually a generic term referring to a variety of steel types. Like all other kinds of steel, stainless steel is made primarily from iron and carbon in a two-step process. What makes stainless steel different is the addition of chromium (Cr) and other alloying elements such as nickel (Ni) to create a corrosion-resistant product. Get price

Heat Treating of Metals

Steel is usually harder than necessary and too brittle for practical use after being hardened. Severe internal stresses are set up during the rapid cooling of the metal. Steel is tempered after being hardened to relieve the internal stresses and reduce its brittleness. Get price

Why Was Iron so Important During the Industrial Revolution?

2020/4/4Iron processing facilities were small and only handled small quantities of iron at a time, making iron production limited in output and expensive. Prior to the Industrial Revolution, the process of iron production involved combining and melting iron with other sources of fuel, primarily charcoal. Get price
