Main benefits of Primetals Technologies reversing cold mills. High production capacity and yield Flexible low-cost rolling of a wide range of products especially for small order lots

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 hardening. The starting material is usually large pieces of metal like semi-finished casting products such as slabs blooms and billets.

An undentified viewer takes a stroll through a hot strip mill via a virtual reality display. animated steel mill (Figure 1). The display was operated by Tippins Incorporated and featured rolling mill line (Figure 5). After approximately 30 minutes in the furnace the slab moves along the line into the reversing rolling mill

SSAB s hot strip mill rolling is conducted in a reversing roughing mill followed by a continuous finishing mill. In the reversing roughing mill the temperature is high and the inter-pass times are long. This allows for full recrystallization to occur during the inter-pass times.

Rolling processes 5-1 introduction Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working called hot rolling owing to the large amount of deformation required.

Aluminum Rolling Mills Temperature Control in the Hot Rolling Mill. Aluminum sheet and plate products are used for a wide range of applications including can stock brazing automotive and aerospace. These industries demand exacting tolerances and precise mechanical properties particularly for new technically challenging high-strength alloys.

reversing cold rolling mill which takes relatively inexpensive capital investment is put into use. a hot coil using a spot welding machine aiming improvement of productivity as well as reduction of unrolled portions with an e ye to reversing rolling mills for use of normal carbon steel having high demand in emerging countries.

Secondary scale on hot strip and the impact on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago the results were never published but of high interestalso maybe later. K. H. Schröder July 2003 K. H.

Aluminum Hot Rolling Reversing Mill Application Overview Aluminum Reversing Hot Rolling Mill Overview Reversing Mill Sample Data From our online testing of the MWx here are some results by alloy and pass at the reversing mill. With its Dynamic ESP Technology no adjustments were required to achieve these results.

x These mills are normally two-high reversing mills with 0.6 -1.4 metres diameter rolls (designated by size). x The objective is to breakdown the cast ingot into blooms or slabs for subsequent finishing into bars plate or a number of rolled sections. x The blooms/slabs are heated initially at 11000 C -13000 C. In hot-rolling of steel the

in hot strip mills slabs of 1 50 to 250 mm thick are rolled to strip 1.5 to 12 mm thick. Conventional hot strip mills consist of roughing and finishing stands. The configuration of the roughing mills varies widely. A mill with one reversing stand is called a semi-continuous mill. A mill with one reversing stand

This is part 2 of the 4-part Aluminum Hot Rolling Mill application note seriesbe sure to check out the rest of the series Application Overview At the reversing mill rolling speed roll bite and coolant flow may be optimized only with a precise real-time knowledge of metal temperature.

Steckel mills are the proven solution for coil production up to 1.5 Mtpy and at the same time represent the most cost-effective choice within the large hot rolling mill family. Recent innovative solutions applied to modern Steckel mills make it possible to achieve high-quality strip that is comparable to the products of traditional hot rolling

In two high reversing rolling mills the rolls rotate ist in one direction and then in the other so that rolled metal may pass back and forth through the rolls several times. A four high rolling mill is used for the hot rolling of armor and other plates as well as cold rolling of plates sheets and strips. Types of Rolling mills

The most common configuration is the single reversing mill. Various mill designs are offered that include 6-high UCMs (Universal Crown Control Mill) ZR mills and 12-high cold-rolling mills with small-diameter work rolls for the efficient rolling of materials of high hardness.

After passing through the reversing hot rolling or "break down" mill the material is fed through a number of non-reversing tandem mills (400–550°C) where the thickness of the strip is set before it is wound at the coiler (240–380°C). The material undergoes a reduction in its thickness from typically 600 mm down to 6 mm.

A Steckel mill also known as a reversible finishing mill citation needed is similar to a reversing rolling mill except two coilers are used to feed the material through the mill. One coiler is on the entrance side and the other on the exit side. The coilers pull the material through the mill therefore the process is more similar to drawing than rolling.

You are guaranteed to benefit from SMS groups long-standing technological expertise in hot rolling processes for the aluminum industry. Out of this comes highly developed technology automation and service packages that feature custom-designed solutions for all your wants and needs.

The strip mill was a major innovation in steelmaking with the first being erected at Ashland Kentucky in 1923. This provided a continuous process cutting out the need to pass the plates over the rolls and to double them as in a pack mill.At the end the strip was cut with a guillotine shear or rolled into a coil. Early (hot rolling) strip mills did not produce strip suitable for tinplate
