Rolling of steel is a metal forming process in which steel is passed through a pair of rotating rolls for plastic deformation of the steel. Plastic deformation is caused by the compressive forces applied through the rotating rolls. High compressive stresses are as a result of the friction between the rolls and the steel stock surface.

There are in general three broad categories of defects in the foundry cast steel products. These are (i) the major or most severe defects which result in scraping or rejection of castings, (ii) intermediate defects which permit salvaging of castings through necessary repairs, and (iii) minor defects which can be easily repaired.

A mill test report (MTR) is a document that shows material origin and composition, as well as material testing results. An MTR is a quality assurance document that tells engineers the exact makeup and performance of the material. MTRs are often provided with every steel material purchase. If not initially provided, an MTR can always be requested.

Historically, working in steel mills quickly separated the men from the boys — even in the 1800s, the steel industry was a place where lots of workers died on the job. By the 21st century, you'd think that things would be pretty safe, that the conditions associated with death would be resolved. Wrong.

The workers at the Steel mill wanted to negotiate shorter working hours, wages were they can make a living, bargaining rights, and wanted union recognition. September 1919, the U.S. Steel Corporation refused to meet with union representatives. As a result, about 300,000 Steel Mill workers walk of the job and went on strike.

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).

C = F/K = F (f — t) / (c-t) = the weight of the concentrate. Recovery %. Represents the ratio of the weight of metal or mineral value recovered in the concentrate to of the same constituent in the heads or feed to the process, expressed as a percentage. It may be calculated in several different ways, depending on the data available.

When hot rolling steel in the laboratory, using relatively small rolling mills, values of 4–20 kW/m 2 K appear to be the correct magnitudes. If modelling hot rolling of steel under industrial conditions, values of 50–120 kW/m 2 K are more useful. In both cases, the layer of scale is an important parameter.
