“…Table I contains average percentage values of different classes of constituents in freshly harvested leaves of mature tobacco plants before drying, the data being obtained by compiling a great number of individual analyses as re-CHEMICAL CHANGES I N T H E HARVESTED TOBACCO L E A F 3 13 c,orded in the literature (6,7,25,32,40,52,81,104,113,119,123,131,201,238,240,242,250,258,262,305,321,335). Since leaves are the raw material of curing and fermentation processes, our survey deals with the composition of the tobacco leaf only, and not with the stalk or root of the plant.…”

“…For the purpose of experimental check of this method calculations were carried out for conditions of rolling H-beam № 35B1, 40K2 and 45B2 from steel 15CrSiNiCu on the universal beam mill of "NTMK". The calculated data were compared with the results of experimental studies [19,20], estimating convergence of calculation and experimental data by the formula ∆𝑃𝑃 =…”

Based on application the physical constraint equations of state of stress and strain of the metal for the isotropic medium, we get expressions for components of stress tensor. The new theoretical method for calculation of contact pressures and rolling force during rolling of double-T section in a universal beam groove was developed. Reliability of the method is confirmed by the results of experimental verification for conditions of rolling of H-beam No 35B1, 40K2 and 45B2 from steel 15CrSiNiCu on the universal beam mill of "NTMK". The average calculation error is 6.4%. The new method is recommended for calculation pass design and technological modes of H-beam rolling on rail-beam and section mills, equipped with universal stands.

“…To determine specific parameters of grooving a statistic analysis of existing rolling patterns was carried out that allowed to take the production experience into account. As a result of correlationregression analysis of statistical samples of 55 groovings [6][7][8][9] the following formulas were obtained which determine:…”

Based on the application of variational principle of minimum total power and statistical generalization production experience procedure for the calculation of roll pass design and process-dependent parameters of double-T section rolling on universal rail-beam mill was developed.With the procedure developed, a computer simulation of rolling of the I-beam 35B2 was performed. It has been shown that the proposed procedure for calculating the calibrations rolls for the I-beam rolling in universal calibers ensures that the effective strain of the profile elements is distributed evenly.The study was made within the project, part of state job in the field of scientific activity No 11.1369.2014/K dated 18.07.2014 (State registration number: 114122470051).
