Autor: P. A. Ibragimov, O. A. Panasenko, A. O. Khalezov, Vladimir Toporov, D. Sh. Nukhov

Publikováno v: Russian Metallurgy (Metally). 2020:1632-1636

The problems of computer simulation of the continuous tube rolling on FQM (fine quality mill) are formulated and solved to study the influence of technological factors on the shape change and the danger of metal fracture. The solution of the problems

New Method of Severe Plastic Deformation of Metals

Autor: Andrey O. Tolkushkin, A. A. Bogatov, A. I. Rudskoy, D. Sh. Nukhov

Publikováno v: Metal Science and Heat Treatment. 60:3-6

The effect of the mechanism of plastic deformation on formation of the submicrocrystalline structure of steels is considered. It is shown that the development of new schemes of pressure treatment of metals with severe alternating deformation is a pro

Production of thin-walled sleeves on the piercing mill at PAO STZ

Autor: B. G. P’yankov, A. A. Bogatov, D. Sh. Nukhov, Vladimir Toporov, O. A. Panasenko

Publikováno v: Steel in Translation. 47:330-333

The screw piercing of blanks on a two-roller mill with mushroom-shaped rollers is modeled by the finite-element method. That permits calculation of the piercing forces and analysis of its dimensional precision. The models are verified by comparing th

Publikováno v: Steel in Translation. 46:620-623

The influence of the temperature, strain, and strain rate on the deformability of low-alloy carbon steel is studied experimentally. Samples are tested on the STD 812 torsional plastometer at Czestochowa Technological University. The hardening of low-

Forging of strip by alternating deformation, with unchanged size and shape

Autor: D. Sh. Nukhov, A. A. Bogatov

Publikováno v: Steel in Translation. 45:412-417

A new tool and technology for the forging of cast ingots without change in the shape and size of the blank are proposed. A hammer shape ensuring uniform working of continuous-cast billet by alternating deformation is considered. The selected hammer h

Finite-Element Modeling of Plate-Rolling

Autor: K. P. P’yankov, D. Sh. Nukhov, A. A. Bogatov

Publikováno v: Metallurgist. 59:113-118

Results are presented from calculation of the geometry of the deformation zone and the kinematics of plate-rolling. The results were obtained using the program packages DEFORM-3D and Q-FORM. A comparative analysis is made of the data based on the len

Distortion of the depression on the rear of the blank in broaching

Autor: A. A. Bogatov, Mikhail Erpalov, D. Sh. Nukhov

Publikováno v: Steel in Translation

When using continuous-cast billet in pipe rolling, it is expedient to roll the billet prior to broaching, so as to improve the structure and properties of the steel. To that end, a three-high screw-rolling mill for billet reduction has been installed
