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. Roll Bite temperatures in slower heavily drafted stands can peak in the region of 300oC, diminishing with the
Hotrolled metal is generally free of residual stresses, and its properties are isotropic. Disadvantages of hot rolling are that ... A 300mmwide strip 25mm thick is fed through a rolling mill with two powered rolls each of radius = 250 mm. The work thickness is to be reduced to 22 mm in one pass at a roll speed of 50 rev/min.

Easy replacement of segment roll for maintenance Power cooling (Enhanced strip cooling system) Hot strip mills often reach their limits in terms of power and flexibility for production of advanced high strength steel grades (AHSS) such as API X80/X100, dualphase, martensitic and complexphase grades.
NOTE: Hotrolling and coldrolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hotrolled or coldrolled. HOTROLLED STEEL. Hotrolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F.
Nov 09, 2013· Cooling hood; Cold rolled steel coils (charge material) are stacked over the base three or four high on top of each other, separated by convector plates. ... the coiling temperature in the hot strip mill is an important parameter. It is to be low (typically around 560 deg C) so that aluminum is present in solid solution prior to the annealing ...
Hot rolled end temperature is 800 ~ 900 ℃, generally cooling in the air, so hot rolling state is equivalent to normalizing treatment. Most of the steel is rolled in hot rolled. Due to the high temperature, the surface of hot rolled steel produces a layer of oxidation sheet, thus has certain corrosion resistance, can be stored in the open air.

Secondary scale on hot strip and the impact on wear is another issue. Stresses from Hertzian pressure in 4high cold mill back up rolls were measured years ago, the results were never published, but of high interest also, maybe later. K. H. Schröder July 2003 K. H. Schröder: A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS
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 metals generally have little directionality in their mechanical properties and deformation induced residual, in certain instances nonmetallic inclusions will impart some directionality and workpieces less than 20 mm ( in) thick often have some directional properties. Also, nonuniform cooling will induce a lot of residual stresses, which usually occurs in ...
