Claims (2)

1. Способ изготовления плит из титановых сплавов, включающий нагрев сляба до температуры прокатки, предварительную прокатку, нагрев раската до температуры прокатки и окончательную прокатку, отличающийся тем, что предварительную прокатку осуществляют в две стадии, на первой из который сляб нагревают до температуры на 30 - 40oC ниже температуры полиморфного превращения и прокатывают с обжатиями 3 - 6% до суммарной степени деформации 20 - 30%, на второй стадии прокатку проводят до суммарной степени деформации 15 - 90%, нагревая раскат перед началом деформации до температуры на 60 - 130oC выше температуры полиморфного превращения, а окончательную прокатку осуществляют в (α+β) -области за 2 - 4 приема с суммарной степенью деформации в одном направлении не более 75% при температуре раската перед каждой прокаткой на 30 - 200oC ниже температуры полиморфного превращения.1. A method of manufacturing plates of titanium alloys, including heating the slab to a rolling temperature, preliminary rolling, heating the roll to a rolling temperature and final rolling, characterized in that the preliminary rolling is carried out in two stages, the first of which the slab is heated to a temperature of 30 - 40 o C lower than the polymorphic transformation temperature and rolled with a reduction 3 - 6% and the total degree of deformation of 20 - 30%, in the second rolling step is carried out until the total degree of deformation of 15 - 90%, heating the lag before de deformations of a temperature of 60 - 130 o C higher than the polymorphic transformation temperature, and finish rolling is performed in (α + β) -region for 2 - 75% 4 doses to the total degree of deformation in one direction at a temperature prior to each rolling of roll 30 - 200 o C below the temperature of the polymorphic transformation. 2. Способ по п.1, отличающийся тем, что перед окончательной прокаткой проводят отжиг раската при температуре на 30 - 50oC ниже температуры полиморфного превращения.2. The method according to claim 1, characterized in that before the final rolling, annealing of the roll is carried out at a temperature of 30-50 ° C below the polymorphic transformation temperature.
