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

Change in Roughing Pass:For 5 roughing passes and 11.1 % reduction in each pass, the area after each pass is calculated below -Initial area = 100 *100 mm^2 = 10000 mm^2After first pass = 10000 -10000*0.113 = 8890 mm^2After second pass = 7903 mm^2 3. Conclusion:Roll pass design not only aims to improve the size, shape and mechanical properties of the rolled products but also it seeks to …

(pdf) numerical simulation in roll pass design for bar rolling

The first one is a classical oval-round roll pass design. The second one is a combination of flat rolls and round roll passes. Relying on the simulation data obtained by FEM, the roll gaps were

(pdf) a new method for roll pass design optimisation

(pdf) a new method for roll pass design optimisation

Such a roll pass design, producing an optimised profile of the intermediate solid at an initial stage, has a marked beneficial effect on the durability of all rolls downstream in the production line. Criteria for improving a hot steel rolling process are process efficiency, resource consumption, product quality and ecological sustainability

Abstract: 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 breakdowns due to the jumps of rolling …
