ﬂow. So, the design of the roll groove geometry and the roll pass sequence are important aspect to be assessed. The pre-diction of the load and torque with different groove designs plays an important role in order to improve the draft during rolling. The roll grooves in a roller and the roll pass sequence in a hot rolling mill are usually ...
May 18, 2015· Thumb rules in rolls pass design Fittings from oval to round must be 0.3 to 0.7. For ovals width to height ratio must be less than 3.0. 13. Spread When the steel is compressed in the rolls it will obviously move in the direction of least resistance, so usually there is not only longitudinal flow but also some lateral flow.
Jan 01, 2019· Reasonable design of roll pass schedule is the prerequisite for a successful shape rolling process. In this paper three dimensional elastoplastic finite element simulation with thermal mechanically coupled analysis is applied to study the roll pass design of the hot continuous rolling of Ф100mm alloy steel round bar from 200mm×200mm square cast bloom.

- The rolling process can be synthesized by one equation: Beta x Gamma x Lambda = 1. Which is a mathematical way of saying that the volume is a constant
Jun 18, 2014· Traditionally, the roll pass design was taken more as art than science. In 1969 a major work, systemizing the principles of roll pass design, was published by Wusatowsky. Since then, the complexity of long product rolling processes has increased. Modern long product rolling mills are built as continuous or semi continuous rolling mills.
Depending on the machine design, bead mills are operated in discrete pass or continuous operation. AVEKA operates a variety of different high-energy bead mill designs that can handle almost any type of dispersion. Grinding media from 2.5 down to 0.3 mm can be used to create ultra-fine dispersions.

Jun 19, 2017· Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.

Create roll and groove drawings Complete analyze of the rolling mill The investment in the WICON will be paid off in a very short period of time by saving just a few hours of downtime or avoiding unsuccessful test rolling of new passes.
A model has been used to design roll passes for the finishing train of a continuous 530 mm billet mill producing 60 mm square billet from input square of 120 mm in six passes.
The analysis of two roll pass design options of ten roughing stands atOJSC "MMK" 370 rolling mill has been performed. The usage of a new form of the roll grooves will allow achieving higher durability of the rolls. Lesser rolls consumption will allow saving up to 800K rubles annually. More uniform load distribution by the stands will reduce the possibility of main mill lines equipment ...
mill is required. Pass Design The leader sections for the multiple slit rolling pro-cess, e.g. square, rectangular or round have to be of very close tolerance. This requires: * Correct pass profile in the rolls * Correct roll gap to ensure no overfill * Correct pass alignment between top and bottom rolls * Sound roll neck bearings and positive roll
Initial rolling condition and roll pass schedule Ф100mm 37Mn5 tube billet is designed to be rolled out by 200mm×200mm cast bloom through the six-pass continuous rolling mill with horizontal (H) vertical (V) alternative arrangement. The roll diameter of the first pass (H1) and second pass (V2) is 700mm and the last four passes (H3,V4, Get Price
