Numerical Modelling of Round Bars Rolling Process in Three-High Skew Rolling Mill HDQT-R 30-12

THEORETICAL AND EXPERIMENTAL ANALYSIS OF ALUMINIUM BARS ROLLING PROCESS IN THREE-HIGH SKEW ROLLING MILL TEORETCZNO – DOŚWIADCZALNA ANALIZA PROCESU WALCOWANIA PRĘTÓW ALUMINIOWYCH W TRÓJWALCOWEJ WALCARCE SKOŚNEJ Technology of round bars rolling on a three-high skew rolling mills

Technology of round bars rolling on a three-high skew rolling mills allows rolling of standard materials such as steel and aluminum, as well as new materials, especially hard deformable materials. The paper presents the results of theoretical and experimental rolling process of aluminum bars with a diameter of 20 mm. As the stock round bars with a diameter of 25 mm made of aluminum grade 1050A ...

Fabrication and angle compensation analysis of skew rolling mill

The rolling process is an excellent method for processing new high performance polymers. Skew rolling, as a highly accurate and highly efficient rolling technology, has been commonly used to enhance mechanical properties and productivity. However, the complexity of the mechanics in the skew rolling process of polymers is a significant challenge for manufacturers and researchers. In this work, m...

Stiffness analysis method of rolling mill based on process data

France : rolling round the curbs.

The French Tobacco Act (the " loi Evin ") has led to the price of manufactured cigarettes doubling since 1992, and to sales decreasing 14.5% from 1991 to 1997. But during the same period, sales of roll-your-own tobacco (RYO) have doubled, because of their lower level of taxation. This phenomenon mainly concerns young people: almost 24% of 12 to 24 year olds say they smoke roll ups, against 17.7...

Idea of the virtual rolling mill laboratory

Laboratory tests are crucial in education and training of engineers. Experimental equipment and process simulators are extremely expensive. It is not possible and justified economically to build such laboratories, for educational purposes, in large number of schools. On the other hand, education and training based on video films, etc., is not adequate and personal contact of students with a pro...
