Definitions
- the traditional process usually begins by smelting material, in which cylinders, commonly called “billets” (technical term) in a range of 8.9 cm (3.5 inches) and 25 inches are cast , 4 cm (10 inches), or greater. Then, these tickets are heated at high temperatures to later be extruded in a high pressure press, or perforated and elongated by mechanical systems that result in what is known in the industry as “pre-tube” which, as we noted, it will be referred to herein as “old pre-tube”.
- This old pre-tube has a predetermined length for the size and weight of the billet.
- the weight of the billet ranges from 75 to 400 Kg, which restricts the size of the old pre-tube because they must be limited to the capacity of extruder presses or drills.
- the old pre-tube goes through a series of drawing processes that basically consist of stretching and reducing the thickness of its walls by passing it through traction by: i. a tungsten carbide die; ii. with a "pepa” or “bullet” or “mandrel”,
- the old system consists in passing a tube through a die or a hollow plate whose hole has tungsten carbide walls of a diameter smaller than said tube.
- the pipe is threaded through said hole (after decreasing the diameter of the pipe at the tip) and a metal tube or cylinder with a diameter slightly larger than the hole in the plate is placed inside the pre-tube.
- a metal tube or cylinder with a diameter slightly larger than the hole in the plate is placed inside the pre-tube.
- the second source of loss is the breakage of material. As the diameter of the tube decreases, the tractions become more intense and the material accumulates strain by deformation in each pass. If there is any imperfection in the tube, it is cut and a loss of material occurs.
- the third source of loss is the final sizing of the product that will depend directly on the length of the old pre-tube or the weight of the billet and the size required by the final customer.
- the production process of the present invention consists in unifying a three-stage production line to obtain a standardized tube that would correspond to an eighth of the traditional line process, these can be seen in Figure 5.
- the vertical continuous casting process is a process that was created in the 70s for the exclusive manufacture of OFHC (oxygen free high conductivity) wire rod.
- An automatic loader machine feeds the foundry homo with copper cathodes, where the molten metal is kept at a temperature of 1160 ⁇ 5 ° C covered with a layer of flake graphite, to partially prevent its oxidation.
- a special cooler is assembled with a graphite matrix, a kaowool cup, a graphite cup and a mortar, all shown in Figure 7.
- the casting process begins with the insertion of a steel tube ("fishing rod") with a piece of perforated steel at the tip (Figure 8).
- this assembly When this assembly is inserted into the liquid metal, it enters the graphite matrix and solidifies on the perforated tip, it is left to rest for a short period of time, and then the rod is pulled upwards with the help of the machine traction and with the pinch rolls ( Figure 9 and Figure 10), when the metal pre-tube has already passed through the traction table, the fishing rod is removed and its tip is cut ( Figure 1 1 ). At that time, said pre-tube is maintained by itself and is taken to the receivers where they are accumulated.
- the said pre-tubes made by this process will be called "new pre-tubes"
- These new pre-tubes have two special characteristics that differentiate them from the old pre-tubes and that make their reduction to marketable sizes difficult. Namely: a. their structural micro ordering, of disordered grains (according to their cooling) and of a large size that they produce: i. the fragility of said pre-tube in the drawing process; Y, I. easy appearance of micro fissures in the drawing process; and, b. its consequent rapid oxidation that generates the rupture of the pre-tube in the process of drawing by the emanation of the free oxide particles.
- the materiality of the tube comprises a metal and / or a nonmetal, a metal alloy, composite metal, metallo-ceramic alloy, ceramic or a polymer, preferably copper.
- An object of the present patent is the sequence of additional steps required to ensure that the new pre-tube (fresh from the vertical continuous strainer) can end up being a marketable product.
- Another object of the present patent is to obtain a tube in which the type of grain required for its application can be selected, which includes a tube with a minimum or zero degree of oxidation.
- Some characteristics of the tube, preferably of copper obtained with the process that will be described below are: that it has homogeneous grains, preferably equiaxial, with an average grain size in the range of 0.025mm to 0.050mm, preferably 0.040mm
- the copper tube chemically has a sulfur concentration range of 2 ppm - 12 ppm, preferably 6.6 ppm, and an oxygen concentration range of 5 ppm - 12 ppm, preferably 10.5 ppm.
- the drawing consists basically of stretching and reducing the thickness of the walls of a tube by means of passing it through traction on a tungsten carbide die with a pepa or bullet or mandrel inside it until the desired result is achieved.
- wire drawing There are several ways to perform wire drawing as shown in Figure 2 and Figure 3.
- the type of wire drawing for new pre-tubes coming from the vertical continuous strainer is the type of floating bowl indicated in Figure 2 already mentioned.
- the new pre-tube is received from continuous casting with measures of 38.00 x 2.50 mm +/- 5%. Then, it is taken to the drawing sector where a double drawing is done thanks to the union and synchronization of two drawing machines that work in tandem. Before starting the drawing, the material is prepared. The new pre-tube is approached towards the dotting machine where it is internally lubricated, a tungsten carbide cup is inserted ( Figure 1) and then a tip is made at the beginning of the rolled tube, which is then inserted into a winder to put on run the drawing line at a constant speed using paraffin as an external lubricant / coolant.
- the new pre-tube passes through the first wire drawing machine ( Figure 12), then through a tension regulator (Figure 13), then the said new pre-tube passes through the second wire drawing machine ( Figure 14) that performs the second section reduction using said lubricant / coolant to finally accumulate the material in a receiver that is inserted in baskets ( Figure 15) in which the material is moved to the next stage (annealing furnace and cooling chamber).
- the material received from the wire drawing machines is manually inserted in the oven inlet guides ( Figure 16).
- the new pre-tube is purged inside with a noble gas, preferably nitrogen.
- a solvent such as turpentine to the outside of the tube to remove the lubricant and other elements that affect the process such as dust, chips or stains, among others.
- the tube enters an oven that, by means of induction coils, heats the metal. Said furnace works at a maximum speed, preferably 40 m / min and maximum current intensity of 5000 Amp.
- the tube passes to a cooling chamber, where the temperature of the metal is reduced to room temperature, to finally wind the tube in a basket. In the passage to said area, protective wax is applied.
- the oven zone and the cooling chamber are constantly saturated with the same purged noble gas, preferably nitrogen.
- the final product is a tube with an equiaxial grain structure with an average size of 0.040 mm.
- oxidation is prevented from forming on the surface of the tube, whereby the final product meets the commercially indicated characteristics.
- the power to start with pre-tubes of smaller diameters allows to reach smaller tube diameters with greater safety and quality because the laundry has been exposed to less stress.
- the percentage of reprocessing in the traditional system at best reaches 25%, with the vertical continuous casting process and the process object of this patent, it is possible to reach 5% reprocessing.
- the homogeneous grain size for 95% of the pre-tube annealed in the induction furnace has an equiaxial grain structure with an average size of 0.040mm ( Figure 17)
- the 1000kg process time via the vertical continuous casting route for a 3 / 4L product is 45% faster than the traditional process.
- the personnel required for the vertical continuous casting production line is 35% lower than that used in the traditional process.
- the combination of the grain size and its hardness give better mechanical properties for the production of the tube to the final consumer.
- Figure 18 Comparative microg raffia of the products obtained in the different processes of the state of the art and the present process of the invention.
- the material After being annealed, the material is processed in a circular wire drawing giving a single drawing of drawing, and finally, the finishing reduction in the straight drawing machines.
- the tip was fabricated so that it could be drawn. Once this was done, the tube was taken to the drawing banks, these banks were approximately 30 to 40 meters in length where the tube was stretched.
