Abstract

The invention discloses a lubricant for wall reduction and drawing of a titanium alloy pipe and a using method thereof. The lubricant is made by uniformly mixing and stirring the following raw materials in percentage by weight: 85-96% of chlorinated paraffin and 4-15% of BN (Boron Nitride). The using method of the lubricant comprises the following steps of: cleaning the titanium alloy pipe, carrying out heat treatment on the titanium alloy pipe after baking, respectively smearing a layer of the lubricant on the inner and the outer surfaces of the titanium alloy pipe after the heat treatment, rolling one end of the titanium alloy pipe, putting a moving core head in the titanium alloy pipe and carrying out the wall reduction and the drawing to obtain the titanium alloy pipe. The lubricant disclosed by the invention has the characteristics of capability of continuous self-lubrication, good lubricant adhering effect, simplicity in composition proportioning, easiness in cleaning and removing, environmental protection, no pollution and the like. By adopting the lubricant disclosed by the invention, the titanium alloy pipe drawing production efficiency can be effectively increased.

Description

technical field [0001] The invention belongs to the technical field of lubricants, and in particular relates to a lubricant for wall reduction and drawing of titanium alloy pipes and a use method thereof. Background technique [0002] Titanium and titanium alloys have a close-packed hexagonal structure at room temperature, and there are few slip systems that can participate in deformation. It is difficult to deform the metal, and it is usually impossible to achieve wall-reducing drawing with a large amount of deformation. At the same time, rare metals such as titanium have a strong affinity with mold materials (steel, tungsten carbide, etc.), and the pressure conditions and temperature rise during the drawing process make the metal easily bonded to the mold, which not only scratches the surface of the product, but also makes the drawing The force increases, the safety factor decreases, the number of broken ends increases, and even the drawing process cannot be carried out. ...
