P. Kucsera et al. Hot Rolling Mill HGC Thickness Control Improvement – 98 – Another way to determine the thermal expansion of the work roll is the modelling of the heat transfer between the work rolls and the strip. This depends on the roll speed, strip thickness, the properties of the strip, roll gap, contact time and cooling parameters.
John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).
rolling. Intermediate annealing is done in either a strand annealer or batch annealer. After an-nealing, the strip is rolled to desired thickness in a four-high, five-stand rolling mill. Rolled strip is continuously annealed in a vertical fur-nace (strand annealer), which is the subject of this article. The annealing furnace consists of a hori-
Continuous Annealing Line (CAL) This line facility changes the crystal structure of steel sheet by heat treatment, and improves properties such as hardness, strength, and elongation. It integrates the 5 processes of cleaning, cooling, heating, temper rolling, and refining, and carries them out in a single line, thus saving space and lowering costs.

3 · A 600 mm wide annealed 304 stainless steel strip 26 mm thick is fed through a rolling mill with two powered rolls each with a radius of 420 mm. The strip thickness is to be reduced to 20 mm in one pass with a roll speed of 75 rpm. (1) Calculate the roll force [MN], torque per roll [kN•m], and total power [kW] required for this operation.

Selective heating of edge and near-edge portions of a strip material is used to increase the ductility of the strip material at these portions and to improve the cold rollability and/or strip annealability of the strip material. The selective heating may be performed either by radiant heating or by induction heating.
Passlines, Strippers and Sideguides: Hot Strip Mill Operations, Volume X The final installment of Hot Strip Mill Operations was written to address the lack of information and knowledge about the passline's function in a rolling mill.
Aimed at the complex demand of hot strip rolling mill in practicing, the configuration of the coiler and the technological process is analyzed. The arithmetic of coiling tension and the control process is introduced. The frame of the tension adjusting system is given. The coiler control sys-
Jan 14, 2017· Rolling of hot strip and strip defects. Rolling is one of the most important industrial metal forming operations. Hot Rolling is employed for rolling of steel slabs to hot strips in hot strip mills. Like any other hot rolling operations, rolling of hot strip is also a plastic deformation of the material of the slab caused by compressive force ...
Slabs are the feed material for hot strip mills or plate mills and blooms are rolled to billets in a billet mill or large sections in a structural mill. The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished 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.
strip rolling as endless type mill. (1) Meanwhile, the conventional non-endless type rolling mills are still used for thin strip rolling. In case fewer stands are used in the conventional non-endless type rolling mills to reduce the cost, the rolling speed is in general a little lower. In a compact hot strip mill…
A twin-stand Steckel Mill combines Steckel technology and tandem rolling. This mill type gives you the capacity to produce high-quality hot strip on a Steckel mill at production rates of 1 - 1.2 million t per year (without roughing stand) or up to 1.8 million tons per year with roughing mill.
Dec 03, 2015· Rolling of steel in Hot Strip Mill. Hot strip mills in these days are either conventional hot strip mills or strip mills for rolling thin slabs. The primary function of the conventional hot strip mill (HSM) is to reheat the semi-finished steel slabs (rolled or continuously cast) to the rolling temperatures and then to roll them thinner and ...
