plate mill — power meets precision Quality plate is about metallurgical precision – high strength and toughness at alloying levels that keep costs down and preserve weldability. It is also about maintaining precise thickness across the full width, as well as consistent flatness to assure fitup in fabrication.
A deflector roll for a strip mill is divided axially into sections to be able to measure the distribution of the strip tension across the strip width. To avoid transmitting the measuring signals from movable parts, the sections of the deflector roll are supported by rollers journalled in stationary holders, the forcemeasuring transducers being built into the holders.

HDL® Brush Rolls. Osborn HDL® brush rolls are used in cold strip lines. Applications such as washing, degreasing and cleaning of strips, activation of strip surface, polishing and finishing of strip surface as well as scale removal after hot and cold mill processes are most common.
These backup rolls are larger and contact the back side of the smaller rolls. A fourhigh mill has four rolls, two small and two large. A cluster mill has more than 4 rolls, usually in three tiers. These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils.

HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a .
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
Roll stack deflection is an important issue in the determination of profile and flatness of a strip rolled in hot strip mill. A simple roll deflection model has been developed to predict the deflection of the finishing stands of a hot strip mill.
system was relatively slow and depended upon the roll separating force, the speed of the mill, and the roll finish utilized. But it was effective enough eventually to permit automatic shape control as long as an adequate shapemeter was installed on the deflector rolls to give an accurate indication of strip .
The mechanical rolling conditions in hot strip mills are precisely defined by various variables, which are taken directly froth the rolling schedule (separation force, torque. speed. strip thickness) or calculated from figures of the rolling schedule and dimensions of the mill (strip reduction, roll diameter etc.).

In many hot strip mills the front stands of finishing group are working with rolls made in High Speed Steels. The success in using these rolls is strictly in connection with the mill technology but also with redressing methods applied in the turning shop. The HSS rolls show an impalpable wear and then the evaluation of roll surface
