Wastewater and Water Treatment Technologies Cheap and plentiful, water was for centuries a production utility which the steel industry took for granted. But in the present scenario, water resources are becoming increasingly scarce due to the growing imbalance between fresh water availability and consumption, hence the access to clean and safe water has become one …
Read MoreFlue Gas Cleaning Technologies and Systems Environmental pollution is one of the biggest problems all over the world at present. From a series of global environmental problems, more and more people have now realized that environment and resources are the basic necessities for the survival and developments of human beings. Flue gases which are the …
Read MoreRolling of Steel Plates in a Plate Rolling Mill Plate steel is defined as a flat, as-rolled or heat treated product of thickness of at least 5 mm and width of at least 1,200 mm. Plate steel is widely used steel product. It falls normally in the categories of carbon steel, high strength low alloy …
Read MoreHistorical Development of Rolling Mills In metalworking, rolling is a metal forming process in which metal is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, to give it a desired shape, and / or to impart a desired mechanical property. In rolling, work material is deformed by compressive forces between constantly spinning rolls. In other …
Read MoreContribution of Steel to the Circular Economy There are two types of economies which exist around the world. These are (i) linear economy, (ii) circular economy. A circular economy is an alternative to a traditional linear economy in which the resources are kept in use for as long as possible, extracting the maximum value from …
Read MoreHydrogen Steelmaking Iron and steel production industry is the single largest sector in terms of total global fossil and industrial emissions, making up around 7 % to 9 % of greenhouse gas (GHG) emissions. At the same time, steel is the primary material component for modern industrial societies. Further increase in the consumption of steel …

Read MoreOptical Microscopy Microscopy studies the enlargement of the image of the objects which are too small to be properly seen by the unaided eye. Microscopy fulfills its task by making use of the radiations (Fig 1) emitted, absorbed, transmitted, or reflected by the sample which is to be observed. The nature of the radiation specifies …
Read MoreNon destructive Testing Techniques There can be inherent microscopic flaws in materials due to crystal lattice imperfections. Also, manufacturing processes such as welding, casting, forging, and surface treatment, etc. can cause further flaws or defects. Further, materials are used under various conditions of stress, fatigue, and corrosion, which can create additional defects or aggravate present …
Read MoreShape Control Technologies in Hot Strip Mill The shape of a rolled strip is characterized by its transverse section profile (crown) and by its flatness. The accuracy of the strip shape is an important parameter which determines the quality of the hot rolled strip. Strip shape is an indispensable factor in determining the market competitiveness …
