2017-10-30 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.

A mathematical model of the plate-rolling process was constructed with allowance for the range of steels rolled on the 5000 mill at the Magnitogorsk Metallurgical Combine and the technological

2003-10-15 only under so called “normal rolling conditions” and even these change continuously with progressive wear in the contact zone. Besides “normal rolling conditions” a stable, theoretical assumption mills experience many different changes in rolling conditions. After a roll change or a mill stop rolls need some time to return to stable

2015-5-12 Thread Rolling Figure 13.16 (a) Features of a machined or rolled thread. (b) Grain flow in machined and rolled threads. Unlike machining, which cuts through the grains of the metal, the rolling of threads causes improved strength, because of cold working and favorable grain flow. Figure 13.15 Thread-rolling processes: (a) and (c) reciprocating

Rolling force is the most important technical parameter for the tandem cold mill. In this paper, the precise models and calculation process for the rolling force are introduced.

The rolling load calculation is a critical parameter when looking for the correct rolling mill setup in steel rolling. The rolling load distribution over the length of the contact arc between the sheet and rolls is a complicated phenomenon and it is affected by several factors

2007-1-1 Hot strip finishing mill is initially set up with rolling conditions such as roll speed, roll gap, and cooling pattern obtained by a set-up model. To improve the accuracy of initial roll speed setting for a 7–stand finishing mill, an equation for predicting forward slip and a compensation method for initial roll speed setting were proposed
