METHOD FOR PIPES PRODUCTION FROM ALLOYS ON BASIS OF TITANIUM

摘要

The invention relates to the ferrous metallurgy. A method for pipes production from alloys on a basis of titanium involves hollow ingot deformation with the desired deformation degree with the pipe obtaining, at that the temperature condition of deformation is supported by the electronic heating, at that ingot is deformed by rolling at a temperature of 800 - 1100 DEGREE C by means of the rollers systems- first on 10 - 30 % from the primary thickness of the ingot wall, second on 20 - 60 % from the previous thickness of the ingot wall, and then the surface layer of the ingot is strengthened by the system of rollers at a temperature of 400 - 800 DEGREE C. The invention allows for receiving pipes from titanium alloys with the strengthened surface.
