IRON AND STEEL
The iron and steel industry including primary and secondary producer s is composed of 79 companie s that produce raw steel at 116 locations. Iron is generally produced from iron ore (t aconite) in a primary mineral production process while steel is produced using both primary and secondary processes. Primary production refers

The 6 Steps To Modern Steel Production ExplainedMetro Steel
Steel manufacturing methods have evolved dramatically since the processes of the industrial revolution began in the mid 19th century. However modern methods are still based on the Bessemer process which was practised over 150 years ago. This was a way to introduce oxygen into molten iron in order to reduce the amount of carbon contained

Method of Making Steel Strapping and Strip
A new continuous process produces steel strapping and 1/2" to 6" strip steel from the rod and strip stock made from scrap steel in mini-mills. The new process creates steel strapping and strip with improved strength and quality due to the absence of microcracks caused by the conventional slitting process. The finished product is

What Is a Steel Casting Casting Process
A steel casting is the product formed by pouring molten steel into a mold cavity. The liquid steel cools and solidifies in the mold cavity and is then removed for cleaning. Heat treating may be required to meet desired properties. This process provides the near net shape and mechanical proper ties required by a purchaser to meet his
