Company Profile:
Michelle Applebaum Research is a Chicago-based equity research consulting firm founded by Michelle Applebaum, formerly a Managing Director of Salomon Brothers. The company provides consulting expertise in the area of steel and steel equities to institutional investors and industry.
Either natural gas or coal can be used to remove the oxygen from iron ore in order to produce a scrap substitute. In gas-based processes, the iron ore is heated in a vessel as reformed natural gas passes through. In coal-based processes, iron ore is combined with gasified or ground coal and heated. The oxygen in the ore combines with carbon and hydrogen in the gas or coal, producing reduced, or metallic, iron.
Industry:Metals
Heat-resistant brick. Because its melting point is well above the operating temperatures of the process, refractory bricks line most steelmaking vessels that come in contact with molten metal, like the walls of the blast furnace, sides of the ladles, and inside of the BOF.
Industry:Metals
A commodity-grade steel used to strengthen concrete in highway and building construction.

Industry:Metals
The process of replacing the refractory lining of a liquid steel vessel. Once it wears out, the brick lining of a furnace must be cooled, stripped, and replaced. This maintenance can be significant because a blast furnace reline may require up to three months to complete.
Industry:Metals
The impurities in mini-mill steel as the result of the mix of metals entering the process dissolved in obsolete scrap. Residuals are key concerns regarding the mini-mills’ recent entry into the flat-rolled market, where high residuals can leave sheet steel too brittle for customer use.
Industry:Metals
The stand of rolls used to reduce steel sheet or plate by passing the steel back and forth between the rolls; the gap between the rolls is reduced after each pass.

rod
Round, thin semi-finished steel length that is rolled from a billet and coiled for further processing. Rod is commonly drawn into wire products or used to make bolts and nails. Rod trains (rolling facilities) can run as fast as 20,000 feet per minute — more than 200 miles an hour.
Industry:Metals
Mill stands place considerable pressure on slabs, blooms and coils to further process the material. There are two general ways of applying the force to the steel — screw and hydraulic systems. * Screw (Incline Plane): This older method used the basic principle of the screw to adjust the space between the mill rolls. Because metal touches metal, these configurations will wear down over time and can cause quality problems. * Hydraulic (Pancake Cylinder): This modern system uses fluid pressure to rapidly adjust the roll spacing several times per second. These minute, instantaneous adjustments allow for superior gauge tracking and higher quality products.
Industry:Metals
Any of the mills in which metal undergoes a rolling process. These include the slabbing mill, hot roll mills, cold roll mills, SR mills, and DR mills. Any operating unit that reduces gauge by application of loads through revolving cylindrical rolls; operation can be hot or cold. The elevated temperature rolling mill is the Hot Mill and is capable of reducing the gauge of a slab 92-99%.
