Titanium and titanium alloy wire rolling is a process of producing coiled or single wire products from titanium and titanium alloy wire blanks (coiled or single) through drawing, including titanium iodide wire, titanium molybdenum alloy wire, titanium tantalum alloy wire, industrial pure titanium wire, and other titanium alloy wires. Titanium iodide wire is used in industrial sectors such as instruments, meters, and electronics. Ti-15Mo alloy wire is the material for vacuum titanium ion pump suction source. Ti-15Ta alloy wire is a suction material used in the vacuum industry sector. Industrial pure titanium and other titanium alloy wires include industrial pure titanium wire, Ti-3A1 wire, Ti-4A1-0.005B wire, Ti-5 AI wire, Ti-5 Al-2.5Sn wire, Ti-5 Al-2.5Sn-3Cu-l.5Zr wire, Ti-2A1_1.5Mn wire, Ti-3A1-1.5Mn wire, Ti-5 A1-4V wire, Ti-6A1-4V wire, etc. They are used as corrosion-resistant parts, electrode materials, welding materials, etc. High strength TB2 and TB3 alloy wires are used in the aviation and aerospace fields.
(1) Heating system and final rolling temperature. The heating temperature of β - type titanium alloy before rolling is slightly lower than the (a+P)/P phase transition temperature. The rolling process is completed in the a+P phase region; Heating of Type 3 titanium alloy in the a+p phase region; (The heating temperature of Type 3 titanium alloy is higher than the p transition temperature. The heating time is calculated from 1-1.5mm/min. The heating temperature before rolling of titanium and titanium alloy billets and the final rolling temperature of profiles are basically the same as the final milk temperature of dairy bars.).
(2) Selection of other process parameters. Due to the large production volume of titanium and titanium alloy rolled profiles, the product length should not be too short and the rolling speed should not be too high. In the actual production process, the rolling speed generally used is 1-3m/s.
(3) Based on the deformation resistance, width expansion value, and elongation of titanium alloy, select suitable rolling mill passes for various steel profiles of titanium alloy to roll titanium alloy profiles. If the batch of titanium alloy profiles is large, a specialized rolling mill for titanium alloy can be designed based on the characteristics of the titanium alloy to roll the titanium alloy profiles.
