The Production Process (With Diagram)

The production function is a short-run production function because it illustrates what happens to output as more and more units of the variable input, labour, are added to the fixed stock of capital. Thus Fig. 13.2 is a graphic repre­sentation of equation (2) which is the short-run pro­duction function for radios.

steel FACTS

production of steel. of steel scrap have been recycled to make . new steel since 1900. This has reduced iron ore consumption by around 35 billion tonnes, as well as cutting coal consumption by 18 billion tonnes. Recycling one tonne of steel . scrap saves 1.5 tonnes of CO 2

How steel is made - a summary of a Blast Furnace

To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. In fact, a very simple definition of steel is "iron alloyed with carbon, usually less than 1%." The following text is taken from the Structural Manual For Ironworkers Manual V-Volume I.

Steel is an alloy made up of iron with typically a few tenths of a percent of carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant need typically an additional 11% chromium.Because of its high tensile strength and low cost, steel is used in buildings ...
