ROLLING
is 300 mm, and the rolls rotate at 100 rpm Calculate the roll force and the power required For annealed copper, it has a true stress of about 80 Mpa in the unstrained condition and at a true strain of 0223, true stress is 280 Mpa FOUR HIGH ROLLING MILL PROBLEMS AND DEFECTS IN ROLLED PRODUCTS Porosity, Cavity, Blow Holes occurred in the

Calculation of Rolling Load and Torque in the Hot
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
