Definitions

  • the present invention belongs to the field of plasma torches. More specifically, the invention relates to a method for controlling the wear of at least one of the electrodes of a non-transferred arc plasma torch.
  • a plasma torch is a system for transforming electrical energy into high density thermal energy.
  • An electric arc caused between two electrodes is typically used to provide the energy required for the ionization of a plasma gas.
  • Plasma torches are used in industry, for example, to make metal deposits or for welding, or to destroy certain products such as hazardous waste.
  • the non-transferred arc torches also called blown arc torches, comprise two electrodes between which is generated an electric arc that is maintained. These electrodes being contained in the plasma torch, the electric arc is confined inside thereof. In contact with this electric arc, the gas flow injected into the torch is heated to very high temperature and is ionized.
  • the gas thus heated flows through the open end of one of the electrodes, called the downstream electrode. Only gas ejected at high temperature, or plasma dart, is therefore visible outside the torch.
  • the temperature of the plasma dart is of the order of 5000 ° C
  • the temperature of the electric arc and, in particular, that of the arc feet is typically of the order of 20 000 ° C.
  • This temperature being higher than the melting temperature of the electrodes, and whatever the material used to make these electrodes, the vaporization of the electrodes at the level of the arc feet is inevitable.
  • the electrodes are typically cooled, they are consumables that must be replaced after a shorter or shorter service time.
  • the longevity of the cooled electrodes can vary from a hundred hours for relatively low power torches to a thousand hours for high power plasma torches.
  • the plasma plummet being inoculated with metal particles resulting from the wear of the electrodes, the selected material (s) must be compatible with the envisaged applications for the plasma torch.
  • the electrodes can also be cooled, for example by putting in place a circulation of water, in general, demineralized.
  • This control of the position of the arc foot on the surface of the electrode can be achieved by injecting a variable flow of plasma gas.
  • such a control is then performed by the sole management of the regulator valve of arrival of the plasma gas. This management does not change the servitudes of the plasma torch.
  • the control of the position of the arc foot on the surface of the electrode can also be achieved by the application of a fixed magnetic field with a mechanical mobility of the permanent magnet generating this magnetic field.
  • Such a control allows a distribution of wear on the surface of the electrode over a range of lengths related to the displacement amplitude of the permanent magnet.
  • this permanent magnet is completely independent of the operating points of the plasma torch, and when it reaches the end of the stroke, the wear is greatly accelerated on the fixing location of the arch foot because the latter then describes a simple rotation. Moreover, the speed of movement of this magnet is generally constant over a defined period of time.
  • the control of the position of the arc foot on the surface of the electrode can still be achieved by the application of a variable magnetic field.
  • the document FR 2,609,358 discloses a non-transferred arc plasma torch comprising a field coil surrounding the upstream electrode of the torch and an electrical circuit for supplying variable DC current to this coil so as to describe at the foot of the arc in contact with the upstream electrode a longitudinal stroke which is superimposed oscillation of the arc foot during this race.
  • This method increases the number of degrees of freedom for controlling the position of the electric arcing feet.
  • this solution is expensive and induces an electrical consumption that is added to the power consumption of the plasma torch.
  • the interest of such a technology disappears for plasma torches having a power of less than 1 MW.
  • this field coil technology in the form of slab is bulky (weight and dimensions), which makes it difficult to implement this type of torch in a constrained environment.
  • the objective of the present invention is therefore to provide a method for controlling the wear of at least one of the electrodes of a plasma torch which is simple in its design and in its operating mode, to optimize the position of the foot electric arc on the surface of this electrode and, therefore, the longevity of these electrodes.
  • the invention relates to a method for controlling the wear of at least one of the electrodes of a plasma torch, this torch comprising two electrodes having the same main axis between which an arc is established, these electrodes being separated by a chamber intended to receive a plasmagene gas, and at least one means for generating a magnetic field placed locally at the said at least one electrode whose wear is to be controlled, in which the arch foot is longitudinally scanned on a portion of the surface of this electrode from an initial position until said arch foot reaches a determined end position of said portion involving the change of this electrode, the longitudinal progression of this arch foot being determined by a function dependent at least the time, f (t) which is fixed.
  • At least the electrical energy consumed by this torch is measured as a function of time since the commissioning of the electrode, these measurements are recorded in a storage unit and determined from the temporal evolution. at least this electrical energy consumed on at least a part of these measurements, an adjustment variable ⁇ (t) of the function f (t) over a period of time ⁇ determined by the state of wear of this electrode .
  • Electrodes having a same main axis that these electrodes are coaxial or that the upstream electrode, marked with respect to the flow direction of the plasma, has the same main axis as the downstream electrode.
  • “Locally” means that the means for generating a magnetic field creates a magnetic field at the level of the electrode whose wear is to be limited, in order to cause the displacement of the arc foot on the surface of the electrode. considered.
  • a set value of the current supplying the field coil corresponds to a given position of the arc foot on the upstream electrode.
  • this torch has a given configuration (geometry of the upstream electrode, electromagnetic characteristics of the field coil, etc.), it is possible to determine experimentally by methods known to those skilled in the art the representative curve of the position of the arc foot on the upstream electrode according to the intensity of the current applied to the field coil.
  • the operating speed of the torch may vary over time, the torch not working, for example, at full speed continuously.
  • the plasma torch can experience periods of standby or power variations over time depending on the applications envisaged for this torch.
  • the wear of the electrode for a set value of the arc current is then slowed down or, on the contrary, accelerated.
  • the adjustment variable ⁇ (t) then makes it possible to take into account either the "supposed state" of the electrode as defined by the function f (t), but its actual state which depends on the actual stresses of the flare. plasma.
  • the adjustment variable ⁇ (t) is a function of the form F (i (t), z (t)).
  • determining the adjustment variable ⁇ (t) can be performed by a computer that controls the control means of the position of the arch foot.
  • this computer controls the supply current of this coil.
  • the Figure 1 shows a non-transferred arc plasma torch according to a particular embodiment of the invention.
  • This torch comprises two tubular electrodes 1, 2 arranged collinearly along a main axis. These electrodes 1, 2 are cooled by a water cooling device (not shown) known from the state of the art and which will not be described in more detail here.
  • Electrodes 1, 2 are separated from each other by a chamber 3 for receiving a plasma gas.
  • a power supply system 4 connected to these two electrodes 1, 2 makes it possible to apply a potential difference between them causing a maintained electric arc.
  • the plasma gas which is supplied by a gas supply source 6 is forced into this chamber 3.
  • This plasmagenic gas is preferably introduced between the electrodes 1, 2 with a swirling motion, or else in a vortex, in order to ensure a sheathing by the gaseous fluid and stabilization of the electric arc.
  • this swirling movement ensures a natural rotational movement of the upstream and downstream arc feet on the surface of the corresponding electrodes.
  • the means for generating a magnetic field advantageously comprises a field coil 7 which is fed with a variable DC current 8.
  • variable DC current is meant a DC current whose intensity varies as a function of time.
  • This field coil 7 is here placed around the upstream electrode 1 to control the position of the upstream arc foot on the surface of this electrode.
  • the intensity I of this variable DC current comprises an intensity I 2 superimposed on an intensity I 1 , I 2 being an oscillation such that I 2 ⁇ I 1 , the variation of the intensity I 1 being chosen in the group including linear variation, stepwise variation, exponential variation, logarithmic variation, variation according to a polynomial function, or a combination of these elements.
  • the plasma torch is fed with a variable DC current whose basic intensity I 1 varies stepwise, each step having a duration of several hundred hours, the wear of the electrode being then by "slices".
  • this intensity I 1 can vary linearly or according to a "curved" law such as exponential or polynomial.
  • the Figure 2 shows the shape that can take intensity oscillation I 2 , which makes it possible to oscillate the foot of arc around an average position and therefore to limit the wear of the upstream electrode.
  • This oscillation can have a sinusoidal shape ( Fig. 2a ), of square ( Fig. 2b ) or triangle ( Fig. 2c ).
  • the amplitude and frequency of this oscillation may vary over time depending on the electrical energy consumed by the plasma torch and the state of wear of the electrode. Typically, the amplitude will be all the more limited as the torch will be in an extreme operating range (low power, nominal power).
  • the frequency of the wave will depend on the enthalpy of operation of the torch.
  • the shape of the wave will be selected according to the observation of the stability of the operating points of the torch. If the torch power varies discretely from one power to another and in a programmed manner, a square shape will be preferred.
  • the plasma torch comprises means 9 for moving said at least one means for generating a magnetic field 7 along the main axis so as to vary the position on the electrode whose wear is to be controlled. foot of the electric arc generated between these electrodes 1, 2.
  • These means 9 here comprise a worm rotated by a motor.
  • the field coil 7 is linked to this screw so that the setting rotation of the worm causes a translation of the field coil 7.
  • this motor may for example be an alternating motor.
