“…The HCCI was chosen for its high wear-resistance and hardness, whereas the MCS for high strength property to resist impacting. Currently, there are several fabrication methods of bimetal, such as casting [5], diffusion bonding [6,7], rolling [8], extrusion [9], cladding [10,11] and powder metallurgy technology [12]. The casting as a simple, economical and effective method for fabricating bimetal has been confirmed [5], as well as was used in the current study.…”

“…As it can be noticed for the corresponding value to the strain rate yield stress value for the aluminum alloy grade 2017A is more than two fold higher than for aluminum grade 1050A. The other properties of the aluminum alloys used in research were determined on the basis of the literature [11,12]. …”

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 and aluminum alloy grade 2017A were used. The rolling process of aluminum bars has been carried out in a single pass. The numerical analysis was carried out by using computer program Forge2011 R . On the basis of theoretical research it has been determined the state of deformation, stress and temperature distribution during rolling of aluminum bars. In addition, the results of theoretical research allowed to determine the schema of the metal plastic flow in the roll gap. Verification of the theoretical research was carried out during the rolling of aluminum bars on the RSP 40/14 laboratory three-high skew rolling mill. From the finished bars were taken the samples to set the shape and compared with the results of theoretical research. Finished aluminum round bars were characterized by low ovality and good surface quality.Keywords: three-high skew rolling mill, aluminum alloys, round bars, FEM, numerical analysis Technologia walcowania prętów okrągłych w trójwalcowych walcarkach skośnych pozwala na wytwarzanie prętów zarówno ze standardowych materiałów, takich jak stal i aluminium, jak również prętów z nowych materiałów, zwłaszcza materiałów trudno odkształcalnych. W artykule przedstawiono wyniki badań teoretycznych oraz doświadczalnych procesu walcowania prętów aluminiowych o średnicy 20 mm. Jako wsad zostały zastosowane pręty okrągłe o średnicy 25 mm z aluminium w gatunku 1050A oraz stopu aluminium w gatunku 2017A. Proces walcowania prętów aluminiowych przeprowadzono w jednym przepuście. Badania teoretyczne wykonano stosując program komputerowy Forge2011 R . Na podstawie wyników badań teoretycznych określono stan odkształcenia, naprężenia oraz rozkład temperatury podczas walcowania prętów aluminiowych. Ponadto uzyskane wyniki badań teoretycznych umożliwiły określenie schematu plastycznego płynięcia metalu w kotlinie walcowniczej. Weryfikację badań teoretycznych przeprowadzono podczas walcowania prętów aluminiowych na trójwalcowej walcarce skośnej RSP 40/14. Z gotowych prętów aluminiowych o średnicy 20 mm pobrano templety, których kształt porównano z wynikami badań teoretycznych. Gotowe pręty charakteryzowały się małą owalnością oraz dobrą jakością powierzchni.
