Cross rolling of the shell on a planetary rolling mill (PSW) with in-line coiling directube® is followed by tube drawing and finishing operations on continuous straight drawing machines, spinner blocks, finishing lines and level winders. BENEFITS AT A GLANCE Reduced eccentricity A shorter production route with higher efficiency Lower copper input
Planetary Rolling Mills: The Planetary Mill is a medium output mill for rolling of steel strip. Its output is less than continuous mills of many stands but more than the reversing two-high or the three-high mill. This mill can be used to roll all metals but it is especially useful for those which have low ductility.
The SMS group developed directube ® to enable coppertube manufacturers to produce high-quality tubes on a highly efficient Basis. Our directube ® system casts tube shells from copper cathodes on a horizontal continuous casting plant. Then a planetary rolling mill directly converts them into mother tubes. This short process route results in high efficiency and lower energy consumption.
This paper presents a completely new approach to the mechanics of the Sendzimir hot planetary rolling mill. Previous work on this subject, by R. Tovini, included determinations for the distribution of the advance of the strip, the draft, the rolling load, the torque and the horizontal backthrust for the whole range of positions which the planetary rolls made, whilst contacting the hot metal.
Steel - Steel - Forming of steel: Forming processes convert solidified steel into products useful for the fabricating and construction industries. The objectives are to obtain a desired shape, to improve cast steel's physical properties (which are not suitable for most applications), and to produce a surface suitable for a specific use.

Feb 28, 2002· The planetary rolling mill (Planetenshrägwalzwerk, PSW), as shown in Fig. 1, has been operated successfully in the roughing rolling process.The advantages of PSW include flexibility of workpiece size, low rolling load, low lateral spread of material, and low temperature drop between the leading and tail ends of the rolled workpiece .Because of its high reduction and continuity, the PSW is ...
May 02, 2017· Planetary Rolling Mill: In this type of rolling machine, a large backup roller is surrounded by various numbers of planetary working rollers as shown in figure. Each planetary roll gives constant reduction. It is used to reduce large thickness in single pass of steel strip. Its rolling capacity is more than cluster machine but less than tandem ...

Repetitive three-roll planetary milling, also referred to as screw rolling, was employed to produce gradient structures in copper or magnesium rods [15, 16]. A sliding wear process was proposed to ...
The rolling temperature and rolling force of planetary mill were in good agreement with the measured results, which indicated that the finite element method would supply important reference merit for three-dimensional thermo-mechanical simulation of the three-roll planetary rolling process.
Jun 15, 2001· Traditionally, most stainless steel rods are manufactured in the roughing rolling process with large reduction ratio by several 2-high rolling mills. Six to eight conventional mills can be replaced when using one planetary rolling mill (Planetenshrägwalzwerk, PSW as shown in Fig. 1) in the roughing rolling process. The PSW mainly contains ...
Continuous rolling by mills using grooved-rolls is generally adopted in blooming and bar rolling. Develop-mentof heavy reduction rolling technology, in which large reduction/pass can bc obtained, is being focused on in order to shorten and simplify the rolling process.
