Chernye Metally

The eighth issue of the «Chernye Metally» journal for 2018 represents its traditional sections, and the articles selection devoted to the 95th anniversary of the Metal Forming chair of the Ural Federal University (UrFU) opens it.

The chair`s specialists in their works proposed a method for physical modeling of the metal destruction process during piercing through alternating torsion of samples, as well as a new technology for fuel pipes manufacturing. The UrFU authors established at a qualitative level that pipe rolling should be conducted in such a way that the decrease or absence of the pipe material hardening effect took place during the deformation process; studied the influence of properties anisotropy on the stress-strain state when electrical steel strip rolling; solved the task of the tube sink drawing using the finite element modeling for three different material models: rigid-plastic with softening, ideal-plastic and rigid-plastic with strengthening.

Specialists of the Lipetsk University in the “Rolling and other metal forming processes” section presented a method to correct the roll gap skew based on the results of temperature measurement of the slab edge in front of a first stand of a hot rolling mill rough group. The authors from Siberian State Industrial University and EVRAZ-ZSMK presented data on the optimal ranges for changes in the vertical and horizontal reductions of the rail profile head to be formed, enabling to obtain the required external radii of the mating surfaces. An overview on the usage of lubricant during strip hot rolling on the example of foreign companies is also presented in the section.

The results of studies of the microstructure and mechanical properties upon tensile of cellular structures, such as VST, of various configurations are presented in the publication of the “Additive Technologies” section.

The “From the History of Metallurgy” section published a mater on the history of the Sestroretsk Arms Plant in the 18^th century which was founded by Peter I in 1720 near St. Petersburg on the coast of the Gulf of Finland.
