“…To produce the feedstock, which was round bimetallic bar, the explosive welding method was used. This method ensures that bimetallic feedstock with the high strength and good mechanical properties of the joint between the core and the clad layer will be obtained [1,2,8,[9][10][11][12][13][14][15]. The rolling of ribbed bars was carried out on a D150 two-high laboratory mill.…”

The paper presents results of theoretical and experimental studies on the process of rolling bimetallic ribbed bars in the finishing pass. The work has determined the effect of the shape of oval preformed strip with a variable clad layer share on the distribution of clad layer thickness in bimetallic ribbed bars rolled in the finishing pass. The theoretical and experimental studies were carried out with the aim of determining the clad layer thickness that will ensure the appropriate corrosion resistance of finished product. A software application, Forge2007 , was used for numerical modeling.Keywords: FEM, bimetallic bars, steel-steel resistant to corrosion, hot rolling, numerical modelling, ribbed bars W pracy przedstawiono wyniki badań teoretycznych i doświadczalnych procesu walcowania prętów żebrowanych bimetalowych w wykroju gotowym. W pracy określono wpływ kształtu pasma owalnego przedgotowego o różnym udziale warstwy platerującej na rozkład grubości warstwy platerującej w prętach żebrowanych bimetalowych walcowanych w wykroju gotowym. Teoretyczne i doświadczalne badania przeprowadzono w celu określenia grubości warstwy platerującej zapewniającej odpowiednią odporność na korozję gotowego wyrobu. Do modelowania numerycznego wykorzystano program komputerowy Forge2007 .

“…Executions of transversely fi nned surfaces differ in manufacturing technology and in geometric, mass, thermo-physical and thermo-aerodynamic parameters [7,8]. Cross-fi nned pipes are produced by the following methods: special casting methods [9][10][11], installing or rolling on alongside with brazing spiral-ribbon fi ns [12], pressing the fi ns along the guide [13,14], knurling bimetallic (aluminum and copper) fi ns on a steel supporting pipe [15][16][17], electric arc or high frequency currents (HFC) welding of fi ns [18]. In the case of cold knurling of fi nned surfaces, the axial, radial, and circumferential components of the cold knurling force have a signifi cant effect on the nature of the deformed metal fl ow.…”

Regulating the deformed metal's fl ow is an important condition for the knurling process. To achieve this, the knurling tool should have a special intake part, where all the main work of plastic deformation would be realized. Depending on the confi guration, the fi ns can be knurled in two ways: either by a radial feed of the tool or an axial feed of a billet (package of billets) or a tool. Using the radial feed method, most types of piece gear parts can be knurled using a more rational radial fl ow of the deformed metal. However, this process is usually characterized by low productivity. The axial knurling method is signifi cantly more productive. In this case, due to the undesirable axial fl ow of the deformed metal, it fl ows to the ends of the billets. As a result, it becomes necessary to introduce additional machining operations and metal waste increases. The article provides an analysis of existing methods of forming fi ns on a cylindrical surface. The authors analyze the advantages and disadvantages of applying the methods in modern conditions, select the most appropriate method, and substantiate the principles of developing tools for cold knurling of fi ns. The purpose of the work was to develop a tool for determining the forces acting in the cold knurling process and study their infl uence on the characteristics of the fi nal products.

The paper presents the results of the experimental tests of Al-Cu bimetallic bars rolling process in multi-radial modified passes. The bimetallic bars consist of aluminium core, grade 1050A and copper outer layer, grade M1E. The stocks were round bars with diameter 22 mm with a copper layer share of 15 and 30%. As a result of rolling in four passes, bars of a diameter of about 16.0 mm were obtained. A bimetallic stock was manufactured using an explosive welding method. The use of the designed arrangement of multi-radial modified stretching passes resulted in obtaining Al-Cu bimetallic bars with the required lateral dimensions, an uniform distribution of the cladding layer over the bar perimeter and high quality of shear strength between individual layers.Keywords: bimetallic bars, explosive welding, groove-rolling, connection quality W pracy zamieszczono wyniki badań doświadczalnych procesu walcowania prętów bimetalowych Al-Cu w wielopromieniowych modyfikowanych wykrojach wydłużających. Pręty bimetalowe Al-Cu składały się z aluminiowego rdzenia w gatunku 1050A oraz miedzianej warstwy platerującej w gatunku M1E. Udział miedzianej warstwy platerującej w przekroju poprzecznym pręta wynosił 15 i 30%. średnica początkowa prętów bimetalowych wynosiła 22 mm, a średnica końcowa po walcowaniu w czterech przepustach wynosiła 16 mm. Wsad bimetalowy otrzymano z wykorzystaniem metody zgrzewania wybuchowego. Zastosowanie zaprojektowanego układu wielopromieniowych modyfikowanych wykrojów wydłużających zapewniło otrzymanie prętów bimetalowych Al-Cu o wymaganych wymiarach poprzecznych, równomiernym rozkładzie warstwy platerującej na obwodzie pręta oraz wysokiej wytrzymałości złącza na ścinanie.
