A narrated description of the steelmaking process, from United States Steel. Covers iron ore preparation, coke-making, blast furnace operation, basic oxygen steelmaking, ladle furnace treatment, continuous casting of slab, the hot strip mill, hot band pickling, cold rolling and more.
Iron Ore to Steel
Overview of the blast furnace operation for production of pig iron from iron ore and coke. Some very basic chemistry of iron and steelmaking is outlined also.
The Blast Furnace
Corus training video describing the blast furnace, and its typical inputs of sinter, iron ore, coke, limestone and hot air. The video clip outlines the iron ore chemical reduction process, the production steps to produce hot metal and slag, and the typical subsequent uses of pig iron.
Blast Furnace Operations
One minute video clip, with description of blast furnace, and of the chemical process for the production of pig iron.
Basic Oxygen Steelmaking
Corus film clip about BOS steelmaking. The video illustrates scrap and hot metal charging, oxygen injection, the slag production process and more, as overall carbon content is reduced from ~4% to about 0.05%.
Dalarna University / SSAB training film which provides an overview of the processes in a steel hot rolling mill. Reheating furnace, roughing mill, coil box and finishing mill operations are described, starting from steel slab. Mill scale production, descaling, strip gauge control, temperature control and similar issues are discussed.
Seamless pipe manufacturing
Film clip which illustrates the seamless tube production process stage-by-stage, starting from large rounds. Reheating, piercing and finishing steps are shown.
Welded tube production process
Corus training film which describes the production process for welded steel tube from flat-rolled strip, using electric welding. Heat treatment for normalising and further hot stretch reduction are discussed also.
Making a horse shoe
Video clip showing the process for production of a steel horseshoe
Forging of steel
An excellent nine minute film which describes ring rolling, open-die forging and hammer forging. Some first class screen shots easily make up for the lack of commentary.
Industrial wire rope production
The production process for wire rope is described, starting from wire strand. Configuration of wire strands, wire lubrication, strand rolling, and strand winding into rope are all described. Strength testing procedures for the steel cable are also shown and the purpose of plastic coating is explained.
