  • Fabrication of Axisymmetric VT1-0 Titanium Workpieces with Isotropic
           Properties

    • Free pre-print version: Loading...

      Abstract: An analysis of high-duty parts made of VT1-0 titanium shows that a large number of them are streamlined hollow axisymmetric parts, which require thin axisymmetric workpieces with isotropic properties for their production. A finite element simulation of the forming of such workpieces needs the strain and temperature dependences of the flow stress. These dependences are derived to describe the forming of workpieces with isotropic properties.

  • Effect of the Temperature–Speed Hot-Rolling Conditions on Scale
           Formation

    • Free pre-print version: Loading...

      Abstract: The influence of the parameters of a through technology on a rolled-in scale defect is analyzed. To study the influence of the temperature behind stand no. 6 of the 2000 hot-rolling mill in sheet rolling shop no. 10 of PAO MMK on the rejection according to this defect, the temperature in the range 1030–1070°C is maintained on rolled strips of steel grades 08Yu and 08(sp, ps, kp), and the products to be processed are then delivered to the 2000 cold-rolling mill in sheet rolling shop no. 5. To study the influence of the reeling temperature on the scale layer thickness, selective sampling from rolls wound with different reeling temperatures is carried out. An analysis of the production of semifinished rolled products for cold rolling with a rolled-in scale defect and metallographic studies have shown that the main cause for the formation of this defect during hot rolling is a high reeling temperature of 604.7 t (24%). The rolled-in scale defect depth is mainly no more than 0.02 mm and is 81 and 67% of the initial cause of scab and underpickling, respectively. An analysis of the influence of the strip temperature behind stand no. 6 on rolling semifinished rolled tin plates shows that a decrease in the temperature decreases the rejection according to the rolled-in scale defect in sheet rolling shop no. 3 and in the coating shop by 3.7 times for the semifinished rolled products upon annealing in bell furnaces and by 1.9 times for annealing in a continuous annealing furnace. The study of the influence of the reeling temperature on the scale layer thickness showed that a change in the reeling temperature from 560 to 730°C leads to an increase in the scale layer from 55.15 to 89.45 g/m2. To improve the surface quality of the finished electro-tinned tin, an experimental technology is proposed: the reeling temperature for semifinished rolled tin plates in the flow of annealing in bell furnaces decreases to 630–660°C instead of 660–690°C according to a standard technology.

  • Wall Thinning at the Vertex of an Angle Piece for Bending in a Tool Die

    • Free pre-print version: Loading...

      Abstract: Finite element simulation of the bending of plates of a sheet material in a tool die is performed in the Deform-3D software package to reveal a relation between the wall thinning of an angle piece and its geometric parameters and the mechanical characteristics of the sheet material. A decrease in the relative curvature or the ratio of the ultimate tensile strength to the yield strength of the material is shown to be accompanied by a decrease in the thinning of the angle piece at its vertex. Approximating relations are proposed to estimate the thinning at the vertex of an angle piece. A comparative analysis reveals discrepancies between the data of finite element simulation and the estimate calculated by the approximating relations.

  • Magnetic Properties of a Hard Magnetic Fe–30Cr–14Co Powder
           Alloy

    • Free pre-print version: Loading...

      Abstract: Experimental design performed with the Statgraphics XVI Centurion software is used to optimize the magnetic hysteretic properties of an anisotropic hard magnetic Fe–30Cr–14Co powder alloy. The following magnetic hysteretic properties are reached: the remanence is Br = 1.24 T, the coercive force is HcB = 50.7 kA/m, and maximum energy product is (BH)max = 35.5 kJ/m3. Regression equations of the dependences of Br, HcB, and (BH)max on the heat treatment parameters of the alloy are derived and adequately describe the dependences within the phase space within variation ranges of selected parameters. The reached level of magnetic hysteretic properties of the alloy is almost identical to that of one of the most widely used industrial alloys, namely, YuNDK24 (GOST 17809–72) [1], although the cobalt content in the alloy under study is lower by more than 40%.

  • Influence of Design Parameters on the Thermal Processes in the Blast Duct
           of a Blast Furnace Air Tuyere

    • Free pre-print version: Loading...

      Abstract: The tuyere designs that meet the conditions of PAO NLMK are simulated in the Ansys Fluent 18.2 environment. A hot blast supply angle of 5° and the inner diameter of the natural gas pipe of 22 mm are found to be rational. For more effective combustion of pulverized coal fuel and natural gas in the blast duct and the tuyere zone of the furnace, the angle of supply of pulverized coal fuel should be increased to 20.0° and the distance between the natural gas nozzle and the flange should be decreased to 30 mm.

           Mills

    • Free pre-print version: Loading...

      Abstract: A model for the heat exchange of roll fittings rolls with a rolled piece and cooling water is considered. This thermal model can be used to determine the temperature of the rolls both in their volume and on the working surfaces. To model the thermal state of the rolls, a three-dimensional heat conduction equation is derived and boundary conditions are selected. The formulated system of equations is solved using the FlowVision program by the finite difference method, by introducing a three-dimensional mesh on a roll and using the operator splitting method.
