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 and even 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 present invention relates to the titanium and copper composite bar method field of manufacturing, especially diameter is less than the manufacture method of the small dimension circular titanium claded copper bar of 20mm.
Background technology
It is manufacture methods such as blast composite algorithm, hot extrusion method that the manufacture method that is used for the titanium and copper composite bar of industries such as chlorine industry, power industry at present mainly adopts, it is the 20-60mm circular titanium claded copper bar that the standard GB of titanium and copper composite bar/T 12769-2003 adopts above-mentioned manufacture method to make diameter exactly, for the small-dimension titanium and copper composite bar of diameter less than 20mm, China does not still have corresponding national standards, and domestic enterprise does not still grasp the manufacture method of above-mentioned small-dimension titanium and copper composite bar.
Summary of the invention
The manufacture method that provides a kind of diameter less than the small dimension circular titanium claded copper bar of 20mm to be solved by this invention, make layer of titanium metal combine with metal copper layer closely, can satisfy instructions for use preferably, can utilize existing equipment to realize the production domesticization of small dimension circular titanium claded copper bar, develop and expand the application market of small-dimension titanium and copper composite bar rapidly, reach foreign exchange earning, obtain the stronger market competitiveness and good economic benefit
The present invention is for solving the problems of the technologies described above, and the technical scheme of employing is:
Manufacture process is divided into: eight key steps such as blank preparation, poling, coating, heat treated, drawing, finishing, the delivery of check finished product packing.
A) blank is prepared, and selects for use the titanium pipe that meets standard-required, red copper bar as blank.
B) poling is that titanium pipe internal surface and red copper bar outer surface are cleared up, and then copper rod is through in the titanium pipe.
C) coating is that aquadag is evenly coated on the titanium tube-surface, and thickness is 0.5-2mm, and optimum thickness is 1-1.5mm, dries.
D) heat treated is that the titanium copper rod after coating is dried is placed in the heating furnace, heating-up temperature 450-600 ℃, optimum heating temperature 550-600 ℃, is incubated 15-30 minute.
E) drawing, supporting suitable mould, the titanium copper rod drawing of heat treated is compound.
F) finishing, the titanium surface removal burr of the titanium and copper composite bar that drawing is made, reconditioning scratches, and excises two terminations.
G) check is observed the compound fastness of section, the uniformity of titanium and copper composite bar circularity.
H) finished product packing delivery, qualified on inspection titanium and copper composite bar finished product is packed delivery.
The invention has the beneficial effects as follows, the small-dimension titanium and copper composite bar that adopts the present invention to make, the titanium copper metal level is fitted firmly, the titanium copper section is even, can utilize existing equipment to realize the production domesticization of small-dimension titanium and copper composite bar as early as possible, replenish a series products, both satisfy domestic market demand for Chinese Industrial Standards (CIS), can export goods and earn foreign currency again, create good economic benefit.
The specific embodiment
Below in conjunction with specification be
The manufacture process of the circular titanium claded copper bar of 8 * 12300mm is described in further detail the specific embodiment:
At first select for use to meet the ISO5832-2 standard, the trade mark is TA1, and specification is
10 * 9223mm titanium pipe and meet GB4423, specification is
The red copper bar of 8 * Lmm; Secondly the titanium inside pipe wall is cleaned, the red copper bar outer surface is cleared up, remove burr, it is even to reach circularity, red copper bar is through in the titanium pipe subsequently; In the 3rd step, with the titanium tube-surface breast of graphiting, thickness 1-1.5mm will be coated with evenly, dry; The 4th step, the titanium copper rod is placed in the heating furnace, heating-up temperature 550-600 ℃, be incubated 30 minutes; The 5th step, the rod of the titanium copper after the heating is used chain drawbench, it is compound that supporting suitable mould carries out drawing, control drawing passes sizing reduction 0.8-1.2mm, drawing speed 1.5-2.5 rice/minute; In the 6th step, handle on the surface of the titanium and copper composite bar that drawing is made, and excises two terminations, and trimmed size is
8.0 * 12300mm; In the 7th step, finished product is checked according to the GB/T12769-2003 standard-required whether section configuration is even, the titanium copper firm degree of fitting, defective such as whether the titanium surface has serious damage, uneven; The 8th step is to the delivery of passed examination titanium and copper composite bar packing.
