Mar 20, 2013. In Jewett, Texas, the Nucor () steel plant is one of the first electric arc furnace plants in the United States. By using the electric arc process to melt and recycle scrap steel, Nucor plants avoid a significant part of the cost and pollution that are involved in integrated iron and steel production with blast furnaces.
The production of steel in an EAF is a batch process. Cycles, or "heats", range from about 1-1/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stages

Answer (1 of 4): The term "steel production" is insufficiently defined to make it discussable. Let me explain. Nucor is the USA's Largest "steel producer." It is also the largest minimill (electric furnace) steel producer. It is also the country's largest recycler (OF ANYTHING!!!). Their recyc...
Nucor Steel sheet is processed to its final thickness by rolling at high temperatures on a hot-rolling mill. This process can be taken a step further by pickling and oiling, which is a method of removing the surface oxides and applying an oil to improve lubricity and provide a more rust-resistant product. Floor Plate.
Steel slag aggregates are fairly angular, roughly cubical pieces with a flat or elongated shape (as shown in Figure 2.13 [49]). They have a rough vesicular nature with many non-interconnected cells, which gives a greater surface area than smoother aggregates of equal volume. This feature provides an excellent bond with concrete binder.
