Modern-day steel production makes use of both traditional raw materials iron and recycled materials to turn them into steel With this in mind here are the 6 steps to modern steel production explained Step 1 The iron making process As iron is the main component of steel it firstly needs to be made

Global steel production is dependent on coal Over 71 of the steel produced today uses coal Metallurgical coal or coking coal is a vital ingredient in the steel making process World crude steel production was 1 6 billion tonnes in 2017

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 The result was a crucible or cast steel

Home Tube mill Steel tube production line Introduction of the roll forming process Roll forming is a continuous metal forming process in which roll forming machines are used to shape metal coils or sheets into parts as the material moves through the machine Roll forming machines consist of sequences of roller die pairs located on

detailers who prepare steel bridge shop drawings specialize in bridges and very few of them detail buildings or other steel structures Most bridge fabricators contract their shop drawing production to independent detailing offices There are a few fabricators that maintain their own in house detailing capabilities Even these

Initially electric steel was a specialty product for such uses as machine tools and spring steel Arc furnaces were also used to prepare calcium carbide for use in carbide lamps The Stassano electric furnace is an arc type furnace that usually rotates to mix the bath The Girod furnace is similar to the Héroult furnace While EAFs were widely used in World War II for production of alloy

Steelmaking is the process of producing steel from iron ore and or scrap In steelmaking impurities such as nitrogen silicon phosphorus sulfur and excess carbon most important impurity are removed from the sourced iron and alloying elements such as manganese nickel chromium carbon and vanadium are added to produce different grades of steel

Steel pipes are made by two different processes The overall production method for both processes involves three steps First raw steel is converted into a more workable form Next the pipe is formed on a continuous or semicontinuous production line Finally the pipe is cut and modified to meet the customer s needs
