Definitions
- the present invention relates to metal tubes and their manufacturing processes and facilities.
- the eccentricity i.e. the variation of the thickness measured in different points of a tube circumference, is large and commonly reached 20%.
- the invention overcomes this drawback by making it possible to obtain a batch of metal tubes in which, for all the tubes in the batch and at some point of a tube whatsoever, the ratio of the difference between the thickness of the wall of the tube at this point and the average wall thickness of the tubes at the thickness average tube wall is less than 7% and commonly attains only 5%.
- tubes made of copper alloy use may in particular be made of tubes made of copper alloy.
- copper alloy mention may be made of cupro-nickel with nickel content varying from 5 to 35%, cupro-tin with tin content varying from 5 to 9%, special alloys such as cupro-nickel silicon, cuproberyllium and cupro-cobalt beryllium. The percentages are expressed by weight.
- the invention also relates to an installation for manufacturing tubes metallic as defined in claim 3.
- the process illustrated in Figure 1 consists in melting, in a first stage, metal 1 in a tank 2.
- metal 1 in a tank 2.
- this metal 1 in a casting machine 3 so as to obtain a blank 4 tubular in the form of a hollow billet.
- we stretch the hollow bill 4 in a drawing bench 5 so as to stretch the tube 6 Cold.
- the tube 6 can then be treated if desired in an oven 7 of heat treatment.
- FIG. 2 The installation according to the invention is shown in Figures 2 and 3. It consists of a casting tool, shown in Figure 2, and a set of cold drawing and heat treatment, shown in Figure 3.
- a graphite core called mandrel 14 which is engaged in the opening of the bottom of the reservoir 12.
- the liquid metal is gradually solidified between the mold 13 and the mandrel 14 in the transition zone T.
- An extraction system 18 ensures the draft 17 is drawn through casting tools.
- An electronic assembly allows the adjustment of the draft parameters.
- the entire cold draft and heat treatment consists, on the one hand, a shrinking machine which allows a reduction of one end of the blank, on the other hand, of a bench or drawing press.
- the blank 17 is mounted on an internal shape 21 called a ball or mandrel.
- the constricted end of the blank extended by an extension 23 or faux-silk is introduced into a die 22, the false silk 23 protruding is hooked by a jaw system 24 on a carriage 25.
- the carriage 25 driven by a chain or a piston 26 pulls the blank between the die 22 and the ball 21.
- An annealing furnace or cell allows annealing after the drawing operation recrystallization of the blank 17.
- the shrinking machine - cold drawing - annealing cycle is repeated from two to n times, depending on the dimensions to be achieved.
- the blanks obtained have a temperature at the outlet of the ingot mold from 990 ° C. Their length is 2200 mm. They are free from defects, their ovalization is ⁇ 0.5%.
