Abstract:

The most effective lubricant of those investigated during rolling of strips of VT-14, VT-15, and VT-16 down to a thickness of 0.8 mm is the synthetic lubricant LZ-203. Destruction full or partial of the metal is observed when strips thinner than 0.8 mm are rolled with lubricant LZ-203. The edges of the strips of alloy VT-14 are especially strongly destroyed. Caster oil is recommended as the lubricant for rolling very thin strips and foils of alloys VT-14, VT-15 and VT-16. Lubricants LZ-142 and LZ-142a, which are complex esters, turned out to have low effectiveness during rolling of titanium alloy into lubricant LZ-142a did not have a noticeable improving effect on this technical lubricant. In separate tests the oxide film formed on the surface of the investigated titanium alloys was observed to have lubricating properties. The possibility of producing a foil from the alloys VT-14, VT-15, and VT-16 was established. In this the strip thickness of 0.13 mm, which was obtained on a duo 150 stand with the application of caster oil, is not the limiting possible thickness. The application of intermediate annealing and more advanced rolling equipment will allow us to produce a foil thinner than 0.1 mm. Author
