Hot rolling • ingots are reheated and bloomed to slab • slabs are reheated and rolled to bar • bar is fed directly to a hot rolling mill • types of hot rolling mills – continuous mill (hot strip mill) – reversing mill – steckel mill (reversing mill with integral coil heating stations on either side).

However, in hotrolling mills, water used for descaling and cooling steel (process water) and water used for cooling rolls and bearings (cooling water) were reported together. inasmuch as the steel indus try generally considers all water used in rolling mills as cooling water.

In a metal rolling process, rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. the place where all the equipment for metal rolling manufacture is set up is called a rolling mill. rolling mills often vary in.

In the process of rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical cold tandem mill, work roll temperatures normally fall in the range of 55oc – 70oc with strip recoil temperatures and interstand strip temperature rarely exceeding 160 oc depending on product.

Rolling mills are not a standard machine tool, nor are they built for stock. they are designed and builttoorder to specifically accomplish an end product or process. at one point during the industrial revolution in america, the united states led the world in hot and cold rolling, plate mills, slabbing mills and blooming mills.

Rolling And Steps In Rolling

Rolling process can be classified either i)based on the temperature of the metal during rolling or ii) based on the arrangement of the rolls and their number or iii)based on the products rolled. i)based on the temperature: rolling can be classified as hot rolling or cold rolling. hot rolling is carried out above rct and cold rolling is carried.

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its crosssectional area.. the types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. because of workability and limitations in equipment, rolling is done in the.

Son why the existing schemes of rolling in the plants with mills mpm and pqf can not be compared. the plant with twohigh continuous mill has a larger reduction at reeling mill in comparison with plant with pqf. in case of three high mill, a part of reduction is transferred to the piercing mill, which therefore, has to pierce thinwalled shells.
