Method of preparing small-dimension titanium and copper composite bar

Abstract

The present invention relates to a method of manufacturing a circular titanium clad copper bar whose diameter is less than 20mm. The method includes eight major steps: blank preparation, pipe lining, coating, heating treatment, drawing, finishing, test and packing and delivery of finished product. A small titanium clad copper bar manufactured by the method has solid titanium clad copper layer andeven titanium clad copper section. Localization of the small titanium clad copper bar can be realized soon by making use of existing equipment, thereby supplementing first category product for Chinese standards, which not only meets the need of domestic market but also creates significant economic benefits.

Description

technical field The invention relates to the field of manufacturing methods of titanium-copper composite rods, in particular to a method for manufacturing small-scale circular titanium-copper composite rods with a diameter of less than 20 mm. Background technique At present, the manufacturing methods of titanium-copper composite rods used in the chlor-alkali industry, electric power industry and other industries mainly adopt the manufacturing methods such as explosive composite method and hot extrusion method. The national standard GB / T 12769-2003 of titanium-copper composite rods is based on the above manufacturing methods method to manufacture round titanium-copper composite rods with a diameter of 20-60mm. For small-sized titanium-copper composite rods with a diameter of less than 20mm, there is no corresponding national standard in China, and domestic enterprises have not mastered the manufacturing method of the above-mentioned small-sized titanium-copper composite rods. ...
