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

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 the calculated and experimental rolling parameters and sleeve dimensions. On that basis, stable rolling of thin-walled 328 × 20.5 and 433 × 26.9 mm sleeves is possible.

Experimental study of the thermal conductivity of toluene at high pressures

The experimental apparatus used for determining the thermal conductivity of toluene at temperatures of 0–180°C and pressures of 0.098-49.0 MN/m² is described, and some of the results are presented. Computing relationships providing an excellent representation of the experimental data are derived.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 17, No. 5, pp. 847–855, November, 1969.
