In the design of the rolling mill plants, it is fundamental to study the behaviour of the deformation process to assess the main process variables (such as torque and rolling force) in all operating this paper, a finite element model is developed and the numerical simulations of the plastic deformation process, in the hot rolling mill of AISI 304 stainless steel, are shown.

Jul 31, 2010 · Mar 31, 2010. #10. Hello: Before you spend any time investigating any motion control solution, perform the following calculation: Tolerance of the shear position ( .010 inches) divided by the linear speed of the product ( 10 inches per second) The result will be a time in seconds, .001 seconds in the above example.

The invention provides a back rinsing method for the filtering system of a stainless steel coldrolling mill. The back rinsing method of filtering system includes the following working steps that: (1) the oil inside a main filtering tank is pumped into a dirtied oil tank for 5 minutes; (2) the filter core of the main filtering tank starts to be blown by air for 6 times each layer, 6 seconds ...

The cold rolling theory is similarly satisfactory in comparison with the experimental results of Ford and it is anticipated that the theory will be more accurate than that of Bland and Ford for small R/h ratios and large of calculation of load and torque for rolling are given in Appendixes for both Coulomb friction and ...

To eliminate a vertically asymmetrical deflection, a rolling mill comprises a device for measuring horizontal deflections of upper and lower work rolls 2, 3 during rolling, a device for comparing values measured on the upper and lower sides and calculating the difference therebetween, and a horizontal deflection controller four determining whether the difference exceeds a predetermined range ...
