Welding Metallurgy Joining of two metal elements by means of welding consists in the formation of a weld between these two elements. The weld is composed of molten, mixed and, eventually, solidified metal of the edges of welded elements as well as of filler metal (consumable). In principle, melting of metal during welding as well …
Read MoreShearing of Sheet, Strip, and Plate Shearing is a method for cutting a metal piece into smaller pieces using a shear blade to force the metal past an opposite shear blade in a progression form. Shearing is widely used to divide large, flat metal such as sheet, strip, and plate. Shearing is a fast and …
Read MoreFlattening, Levelling, Slitting, and Shearing of Coiled Flat Steel Product Hot strip mill and cold rolling mill produce steel strips in varying widths and material thicknesses. These plates / sheets are typically coiled for efficient handling, transport, and further processing. Steel coils are processed in several ways namely (i) it can be ‘slit’ into a …
Read MoreDeep Drawing Process for Sheet Metal Deep drawing is a sheet forming process in which in its simplest form, a cylindrical shape or alike is produced from a thin disc of sheet metal by subjecting it to a compressive force (while it is held between a die and blank holder) through a circular punch which …
Read MoreCold Heading Process Cold heading is a forming process of increasing the cross-sectional area of a blank, which is carried out at room temperature, and at one or more points along its length. The material flow over the length where the cross-sectional area increases and the length decreases. It is identical to conventional upsetting. Along …
Read MoreRing Rolling Ring rolling is one of the metal-forming operations which decreases the thickness (cross section) and increases the diameter (circumference) of the work-piece by squeezing effect as it passes between two rotating rolls. It is an advanced technique, extensively used to produce seamless rings which are normally being used as flanges, pipe flanges, ring …
Read MoreHot Extrusion Process and its Application for Steel Extrusion is a compressive deformation process in which a block of metal is squeezed through an orifice or die opening in order to get a reduction in diameter and increase in length of the metal block. The resultant product has the desired cross-section. Extrusion involves forming of …
Read MoreTime Temperature Transformation Diagrams Time has influence on phase transformation. The rate of transformation is dependent on the time and the temperature. Phase diagrams describe equilibrium microstructural development which is achieved at extremely slow cooling or heating conditions. The phase diagrams give no information on the time which is taken to form a phase as …
Read MorePhase Diagrams A phase in a material is a region which differ in its microstructure and or composition from another region. It is homogeneous in crystal structure and atomic arrangement and has same chemical and physical properties throughout. It has a definite interface and able to be mechanically separated from its surroundings. A component is …
Read MoreAutomation and Control in Wire Rod Mill Steel wire rods are the key product of steel industry and have multiple uses. They are used as the material for fasteners, springs, bearings, wire ropes, chains, cables, wire meshes, wire fencings, tyre cord, reinforcement in railway sleepers, and several other uses. They are used for the components …
