A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.
Metallurgy is a subject evolved over a few millennia, at least the past 3000 years, probably since the dawn of known human history. Old Greek, Hebrew and Hindu scriptures allude to metals like gold, silver, copper, iron, lead, and tin as well as nonmetals like sulfur and carbon [1].Ancient Greek philosopher Heraclitus among others believed that all substances had a single component.
No substance has been as important as metal in the story of man''s control of his environment. Advances in agriculture, warfare, transport, even cookery are impossible without metal. So is the entire Industrial Revolution, from steam to electricity. Nature entices man into the adventure of metallurgy by an initial gift of an almost magic charm.

Powder metallurgy offers the following specific advantages. Parts can be produced from high melting point refractory metals with respectively less difficulty and at less cost. Production rates are high even for complex parts primarily because of the use of automated equipment in the process. Near net shape components are produced.

A given metal can reduce the oxides of all other metals whose lines lie above theirs on the diagram. For example, the 2Mg + O 2 ==> 2MgO line lies below the Ti + O 2 ==> TiO 2 line, and so metallic magnesium can reduce titanium oxide to metallic titanium. Since the 2C + O 2 ==> 2CO line is downward-sloping, it cuts across the lines for many of the
the various types of stainless steel, it is necessary to have an understanding of what stainless steels are. It is important to know what different grades of stainless steel are available, why they perform satisfactorily and why they sometimes do not. In most cases, selection of the proper stainless steel leads to satisfactory performance.
The requirements listed below for the extraction of the specimen are linked to how to select the specimen, but also to the effects introduced to the material during the cutting process and to the cutting process itself. The specimen must represent the features …
The process of shaping metals into semi-finished or finished forms by passing between rollers is called rolling. Rolling is the most widely used metal forming process. It is employed to convert metal ingots to simple stock meers like blooms, billets, slabs, sheets, plates, strips etc. In rolling, the metal is plastically deformed by passing
What is Metallurgy? Metallurgy is defined as a process that is used for the extraction of metals in their pure form. The compounds of metals mixed with soil, limestone, sand, and rocks are known as minerals. Metals are commercially extracted from minerals at low …

Ferrous metallurgy, the metallurgy of iron and its alloys, began in prehistory.The earliest surviving iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel. It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores from at least Greece to India, and (more
