Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work starting material is usually large pieces of metal, like semifinished casting products, such as slabs, blooms, and billets.
Cold rolled steel is stored and sold in coiled form after rolling. Steel comes in many grades, specifiions, shapes, and finishes—the World Steel Association lists over 3,500 different grades of steel, each with unique properties. The various types mean that steel can by widely used in infrastructure, appliances, vehicles, wind turbines, and many more appliions.
to which ArcelorMittal South Africa produces hot strip mill products. Tolerances are based on EN 10051 or ASTM A568M/635M. When hot rolled strip is produced in accordance with JIS or any other international specifiion, tolerances in accordance with that particular specifiion will apply.
A temper mill is a steel sheet or steel plate processing line composed of a horizontal pass cold rolling mill stand, entry and exit conveyor tables and upstream and downstream equipment depending on the design and nature of the processing system.. The primary purpose of a temper mill is to improve the surface finish on steel products.. Components. A typical type of temper mill installation ...

rolling mills with regardsto better strip'ssurface qua lityand for higher productivityof the rolling mills. A compound roll with the outer layer made of high alloyed steel corresponding to the familyof alloysused for cutting tools, which iscalled HSS rolls wasdeveloped and introduced into hot .
During finish rolling the strip is cooled by the rolls and cooling water, but the temperature is also increased during deformation. Cooling on the run out table is also not a continuous action. Therefore neither an isothermal nor continuous TTTdiagrams are able to describe exactly the transformation during rolling and cooling in a hot strip mill.
Hotrolling. Two separate rolling mills are employed to process the raw steel blooms into rebars and highquality steel bars to be used in the automotive industry or in machine construction. To this end, the blooms are once again heated up in a pushertype or in a walkingbeam furnace respectively prior to hotrolling into the size requested by ...
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

Hotrolled coils (HRC) are a type of sheet product resembling a wound steel strip and are produced at hotrolling mills. These products are widely used for construction, the machine industry, car manufacturing, the production of generalpurpose, construction, oil and gas and specialpurpose pipes, and as a workpiece for the further production of coldrolled products.
