Gavriukov O. V. The determination of the static increase in belt tension during the length change of the conveyor conveyance // Scientific Herald of the DSEA. – 2016. – № 1 (19Е).

There has been represented the research on the theoretical dependences of the static increase in belt tension at working and shut-down drive during the non-uniform acceleration of the length change of the conveyor conveyance. It has been determined that in case of elongation of the conveyor static increase in tension of a reel of a mobile station depends on the conveyor operating regime and resistance force of the belt; it does not depend on travel speed of the mobile station when the belt of the lengthening conveyor accelerates and the drive is shut-down. In case of shut-down conveyor extension the static increase in tension of the reel of the mobile station is in two and more times higher than the belt tension of the reel of the mobile station of the lengthening conveyor with working drive.

Gribkov E. P. Selection of process parameters of powder strip rolling to provide a uniform distribution of the powder core density // Scientific Herald of the DSEA. – 2016. – № 1 (19Е).

On the basis of the analysis of the realization results of the finite element model for powder strips in a metal shell rolling it is found that the most uniform distribution of the powder core density regulated by the standards is observed at the reduction level of 25 ... 35%, while for powder strips with width 10 ... 15 mm the recommended value of the reduction should not exceed 25%, for 20 mm wide strips– 35% with rolls radius which is more than 50 mm.

Zligorev V. N., Markov O. E., Kosіlov M. S., Nagіev N. I. Using of convex dies to improve the quality of large plates // Scientific Herald of the DSEA. – 2016. – № 1 (19Е).

Effect of wedge convex dies angle and depth of the concavity faces on metal elaboration in the surface layers of forging such as plates was considered in the paper. It was found, that increasing wedge convex dies angle and depth of the concavity faces decrease the elaboration of surface metal layers under dies. The angle 140° gives the lowest stagnant zone, but further forge leads to the formation of clamps. The intensive metal elaboration, reduce stagnation zone and ensuring absence of defects it is necessary to obtain the four-ray workpiece with 15 ... 25% depth of the concavity faces by dies with angle 160°. Forging in dies with this angle provides shackling of axial defects and lack of concavities on the surface of the finished forgings. These results are explained by index of rigidity of stress state throughout the whole section during the formation of final forging.

The study of the formation of tear cracks in low-carbon and low-alloy steel joints made by electroslag welding was done. To evaluate the resistance against tear cracking, quantitative criterion was selected – the maximum displacement of the upper edge of the welded sample (Δ), in which a welded joint is not yet cracked, was determined for the selected steels. The resistance against tear cracking of joints of 08ГДНФ, 20ХНМФ, 16ГНМ, 25Х3НМ and St. 3 was studied. The greatest crack susceptibility has 25Х3НМ steel, having criterion Δ = 3,2 mm, the smallest susceptibility was observed for St. 3 (Δ = 7,68 mm). It is established, that during electroslag welding of dissimilar steels, workpiece made of steel, less susceptible to tear cracking, does not affect the Δ -criterion of steel which is more sensitive to their formation.
