3. Four High Rolling Mills: In this type of mill, there are four parallel rolls one by another. In this operation, the rotation of the first and the fourth rolls take place in the opposite direction of the second and the third rolls. The second and third rolls are smaller to provide rigidity in necessity. So those are known as back up rolls.

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 interest - also, maybe later. K. H. Schröder July 2003 K. H. Schröder: A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS File: SCHROEDER_ROLLS_010703.DOC

tandem rolling mill or continuous rolling mill: tandem rolling mill process. It is a modern rolling mills and the rolling is done by one pass. The rolling is done in several passes for traditional several stands and reduction that take place successive roll. The number of stands like as 2 to 18. Those are either hot or cold rolling mill types.

Sep 11, 2014· Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.

A cluster type rolling mill intended to provide work roll sizes in the range between the small sizes available with current cluster mill designs and the large sizes available with current four-high mill designs is disclosed. This mill combines the advantages of existing cluster mills (heavier reductions per pass and between anneals) with the advantages of four-high mills (easier to maintain ...

NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. Hot-rolling 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.

The history of the Sundwig 20-high rolling mill begins in the first half of the last century, when Sundwig developed a multi-roll cold rolling mill in 1930. Just a few years later, the first alligator-type 20-high rolling mill was built, followed in 1958 by the first 20-high rolling mill …

Combination: A combination rolling mill is a versatile "two-in-one" type of metal rolling mill that permits both 2-HI and 4-HI rolling operations. Tandem: Tandem rolling mills are used for multiple pass rolling, combining two or more mill stands. Tandem mills are often used with turks heads, edgers, dancers, inter-stand tensiometers, payoff ...

Cold Rolling Mill (Type A) REFERENCE TYPE A. Four-High Cold Reversing Mill. Material: Low and Medium Carbon Steel. Max. entry strip width. 1300 mm: Max. entry strip thickness. 4 mm: Min. exit strip thickness. 0.2 mm: Max. coil weight. 25 t: Max. rolling force. 1800 t: Max. rolling …

The half-products are then fed to cold reduction mills. The metal is rolled to the thickness of 0.5…3 mm in case of mild steel and 0.5…5 mm in case of stainless steel . The material is cooled by the use of oil which also acts as a lubricant during the rolling process.

Shape and Gauge Control of Strip in a Cold Rolling Mill The economic efficiency of metal rolling processes is strongly correlated to the quality level of the end-rolled products. The latest efforts to increase the quality of the end rolled products in rolling processes have been mainly focused on the large-scale application and use of ...

In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes. Roll stands, holding pairs of rolls, are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams ...

Achenbach OPTIMILL®. Cold Rolling Mills. Achenbach strip rolling mills reliably produce best strip qualities even at maximum rolling speeds, maximum rolling widths and highest coil weights. Designed either as 6-high or 4-high rolling mills they are always tailored to the specific operation purpose. Special applications, e.g. as bright rolling mills, require the 2-high rolling mill design.

Apr 28, 2015· Thus, it was desired to develop a new type of mill which is capable of controlling the rolled strip shape even with changes in rolling conditions. The performance of a conventional 4-High mill is not satisfactory in these requirements. A new 6-High cold rolling mill (hereinafter HC-MILL) has been developed in order to solve these shape problems.

Tandem cold rolling process involves large number of interrelated parameters. In such condition, a mathematical model is required for calculation of optimized mill set-up schedules.

Meticulous care is taken in grinding the surfaces of cold-rolling mill rolls and in carrying out annealing and pickling operations of the products so as to provide attractive surface finishes inherent to stainless steel. Products requiring finishes ranging from No. 3 to Buffing polished and hair-line finishes can also be produced to order.

A temper mill is a steel sheet or steel plate processing line composed of a horizontal pass cold rolling mill stand, entry and exit conveyor tables and upstream and downstream equipment depending on the design and nature of the processing system.. The primary purpose of a temper mill is to improve the surface finish on steel products.. Components. A typical type of temper mill installation ...

The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

In recent years, cold rolling department established the idea of "standardized, precise, innovative, sharing", and committed to building a world-class cold rolling base, and become the backbone power for HBIS Tangsteel accelerating international development, creating international high-end brand, and building the most competitive steel enterprise.
