In this study, the analysis of influence temperaturevelocity parameters of radialshear rolling (RSR) on structure and properties of A1050 (%) aluminum alloy using the finite element modeling was carried out. During RSR process, the nonuniform change in temperaturevelocity parameters occurs in the volume of workpiece. The deformation temperature is one of the main influencing ...
A combination of radial shear rolling of a workpiece with a diameter of 15 mm to 12 mm bar in one pass and subsequent rotary forging in one, two and three passes to obtain bars with diameters 11 ...
Untuk meningkatkan kapasitas produksi rolling mill, cold rolling mill reversibel umumnya memiliki persyaratan pengereman mulai cepat. Saat ini, peralatan kami sebagian besar mengadopsi konverter frekuensi untuk mengontrol rasio kecepatan antara setiap rolling mill, sehingga tulangan berjalan dengan lancar saat melewati setiap rolling mill.
of a flying crank shear in 1700 mm continuous plate and sheet rolling mill. Modeling Flying Crank Shear A typical crankrocker flying shear is schematically depicted in Fig. 1. An arrangement drawing is shown in [3]. The cutting of strip is realized by two levers; each holding a cutter knife, on the top and bottom side of the strip ...

Hot shears are designed to cut the rolling stock at the rolling temperature. Cold shears are used to cut the rolled product in to desired saleable lengths. The type of shears normally used in rolling mills are (i) crop and cobble shear, (ii) cooling bed dividing shear, and (iii) rotary shear. The crop and cobble shear is used in hot rolling ...
Rotary Shear CTL is installed on the rolling production line to cut the head and tail of the rolled piece transversely or cut it to a fixed length. During the movement of the rolled piece, the relative movement of the shear blade will cut the rolled piece. The schematic diagram of the fourbar linkage flying shear mechanism is shown in Figure 1.
