In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallizationtemperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature…A STUDY ON ISSUES FACING THE STEEL RE ROLLING MILLS,Steel Re Rolling Mills (SRRMs) have an important role the field of constructions.

27.11.2015· Understanding Rolling Process in Long Product Rolling Mill Steel rolling consists of passing the material, usually termed as rolling stock, between two rolls driven at the same peripheral speed in opposite directions (i.e. one clockwise and the second anti-clockwise) and so spaced that the distance between them is somewhat less than the thickness of the section entering them. In these conditions,What Is A Rolling Mill? | Metal Processing Machinery,,Roll stands, holding pairs of rolls, are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock, and so on), bar stock, and rails. Most steel mills have rolling mill divisions that convert the semi-finished casting products into finished products.Steel - Manufacturing Processes - Oxygen, Ingot, Hearth,,Continuous casting of steel produces an endless length of steel which is cut into long slabs or blooms that are ready for shaping in rolling mills. Molten steel is poured into the top of a continuous casting machine and is cooled by passing through a water-cooled mold. Pinch rolls draw the steel downward as it solidifies. Additional cooling is provided by water sprays along the travel path of the solidifying metal.

For coping up with this increasing demand we equipped ourselves with advanced steel making technology. Setting up a Captive Power PlantA brief history of metal rolling for sheet and plate,,However, as these techniques became more widely known, demands for products coming from metal rolling increased. There is evidence for rolling of lead and tin on simple 2-high mills with cast-iron rolls at the beginning of the seventeenth century. At this point rolling mills did not process the high volumes of metal that we see today. In addition, the required quality of these early products was ‘poor’ if we

In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygen and entrainedRolling processes - Al-Mustansiriya University,consistently during rolling. For steel, the desired temperature for rolling is around 1200_C (2200_F). The heating operation is called soaking, and the furnaces in which it is carried out are called soaking pits. From soaking, the ingot is moved to the rolling mill, where it is rolled into one of three
