Filed: 1998-01-15
Abstract: A process for thermal treatment of rails consists in connecting the rails in a continuos thread with elastic bending rails, heating under tempering the rails heads with high frequency currents in the direction of overall length. Heating under tempering is carried out in two stages, at the first stage heating is carried out to 1050-1100 °С, thereafter short-term intermediary subcooling to the temperature of 820-860 °С is carried out for 10-25 s, at the second stage heating to 920-980 °С is carried out with stabilization thereof. After the second stage of heating primary cooling to 480-380 °С is carried out with changeable rate and self-tempering. The self-tempering is carried out in the temperature range of 520-400 °С for 55-90 s, thereafter the secondary cooling is carried out. While secondary cooling rails are bent along the curve with a maximum curvature on the base in the heating and cooling zone to the value providing equalizing residual stresses arising in the rail head while thermal treatment.

Granted: 2004-05-27
Abstract: FIELD: production of pipes resistant to action of attacks of different corrosion factors and mechanical destruction. SUBSTANCE: the invention presents a method allowing to increase resistance of pipes against corrosion and mechanical attacks and is dealt with production and utilization of such pipes in the systems exposed to action of corrosion and mechanical effects. The technical result is achieved by formation on the pipes surfaces of residual squeezing voltages increasing the pipes resistance against corrosion-mechanical shattering. The purpose is achieved by heating of pipes with the joule heat and with simultaneous cooling their surfaces by a cooling agent. After refrigeration and alignments of temperatures along thickness of walls, the residual stresses of squeezing are formed on the pipes surfaces, and in the middle layers of the pipes walls - the residual tensile stresses. As a result resistance of the pipes surfaces against corrosion-mechanical shattering is increased. EFFECT: the invention allows to increase the pipes resistance against corrosion-mechanical shattering. 2 ex
