Titanium Pipe Study on Casting Material of Titanium Tube

Study on Casting Material of Titanium Tube

    With the titanium tube applications continue to expand, the amount is also rising. Our titanium tube has been in the construction of the application, in order to make more scientific construction to the majority of users to provide high-performance titanium tube.

    Pay the reward is always paid, the customer used our production and processing of titanium tube after the evaluation is very high, the establishment of a long-term relationship, but also for the Division I introduced titanium tube customers.

Titanium tube

The research on refractory materials for molds has always been associated with titanium tube and titanium alloy tube crucible materials. Based on the kinetic aspects, the crucible material has a long time to contact with the titanium liquid during melting, The contact material is much shorter, so the available crucible material can be used as a casting material for titanium tubing.

    Materials that have been studied include carbides, nitrides, borides, sulfides, oxides, rare earth oxides, fluorides, oxyfluorides, sulfur oxides, and refractory metals such as W and Mo. Only a handful of materials have high chemical stability to titanium fluids, including ThO2, certain rare earth oxides, TaB2, Npc, certain rare earth sulfides and certain rare earth oxyfluorides.

Titanium tube welding process is very general it

    Pipe cutting and groove processing of pipe; pipe cutting and groove processing should be carried out in a special workplace using mechanical processing methods. Processing with non-polluting media to clean water to prevent oxidation. The tool should be dedicated and kept clean to prevent contamination of the iron. Processing of a good nozzle should ensure that the surface smooth, no cracks, heavy skin and other defects. The maximum inclination deviation of the incision plane does not exceed 1% of the pipe diameter.

    Surface cleaning: with austenitic stainless steel wire brush to remove titanium tube all welding surface and groove near the 100mm within the rust, paint, dirt, dust and can react with the titanium debris. With the wheel dressing processing surface, remove the flash, burr, convex and other defects.

Titanium tube

Will be titanium tube, accessories aligned, folder, the axis shall not be offset, the gap is uniform, and should prevent the titanium tube in the assembly was damaged and contaminated. Avoid forced grouping. The welding process is the same as the formal welding process.

    Titanium tube degreasing treatment: with celluloid sponge dip sulfur-free ethanol or sulfur-free acetone on all welding surfaces and groove near the 50mm all do degreasing treatment, the treated surface should be no residue. Welding: should be carried out under the conditions specified in the relevant standards.

 How to improve the titanium tube welding method?

    For the titanium tube has a variety of welding methods available, the most widely used is the inert gas protection arc welding (arc welding), other such as plasma welding, vacuum electron beam welding, spot welding, brazing and vacuum diffusion welding are also There are applications. However, the commonly used oxygen-acetylene gas welding, manual arc welding, carbon dioxide gas protection and hydrogen atom welding are not suitable for welding. Because titanium at high temperatures with oxygen, chlorine. Hydrogen and other gases will be a strong reaction, the melting of the weld will be forced to weld completely brittle, only in a vacuum or protective atmosphere, put the gold was only weldability.
