Definitions

  • the present invention proposes to produce a quenching device providing a quenching quality greater than that obtained with the various existing systems.
  • this invention relates to an inner and outer quenching device for tubular parts, in particular tubing steel characterized in that it successively comprises in the direction of advancement of the tubes: - a series of primary quenching rings through which the tube to be quenched passes, - a spillway tank filled with quenching liquid and comprising an orifice for the tube, this orifice being provided with a shutter valve and at least one high-pressure quenching ring, - a plurality of rollers or guide rollers deposited in the overflow tank for routing by turning the tube passing through the tank, means ensuring the internal quenching under pressure of the tube passing through the tank, and, - Means ensuring the recovery of the quenching liquid discharged from the overflow tank, its filtration and its recovery and pressure rise for, on the one hand, the supply of the tank and on the other hand, the high pressure supply of the rings quenching and internal quenching means under pressure.
  • the means which ensure the internal quenching under pressure of the tube passing through the overflow tank are produced in the form of a retractable lance introduced into the bore of the tube and supplied with quenching liquid under pressure, this liquid quenching being injected into the tube preferably in the direction of movement of the latter in the back weir.
  • a series of secondary quenching rings supplied with quenching liquid under high pressure is optionally provided in the overflow tank, the rings being used to enhance the external quenching effect as a function, in particular, of the grade, diameter and thickness of the tubes to be quenched.
  • the primary quenching rings are put into service in a clocked fashion, from downstream to upstream, considering the direction of movement of the tube in the device, as the penetration of the latter into the overflow tank.
  • the quenching device which is the subject of this invention comprises a series of primary quenching rings 12a, 12b, 12c, 12d through which the tube T to be quenched passes, moving on guide rollers. 10, in a known manner.
  • These outer primary quenching rings can be of any type, for example tangential or lip.
  • the device comprises a weir tank 14 containing the quenching liquid, through which these tubes T are moved, the length of the tank 14 being greater than that of a tube T to be quenched.
  • the level of the quenching liquid (for example water) is kept constant by means of a regulation system of conventional type actuated by the floats high 50 ⁇ and low 50.
  • a control system is provided, for example by photoelectric cell, for the opening of the valve 36 and the commissioning of the inlet ring 16.
  • the orifice of the overflow tank 14 comprises two inlet rings 38 and 40.
  • the ring 38 is a fixed high pressure ring and the ring 40 is of the high pressure type, the diameter is adjustable according to that of the tubes to be quenched.
  • the rings 38 and 40 are supplied under high pressure by a pipe 42.
  • FIG. 2 an exemplary non-limiting embodiment of the system ensuring the opening and closing of the valve 36 ensuring the closing of the orifice is shown.
  • the system essentially comprises a jack 46 actuating a set of articulated connecting rods 48 at the end of which the valve 36 pivots.
  • a seal system such as 44 provides sealing.
  • means for carrying out the internal quenching under pressure of the tube T passing through the tank consist of a retractable lance 22 introduced across the tube T to inject the liquid therein high pressure quenching and, optionally, a plurality of high pressure secondary quenching rings 18 and stirring blades such as 28.
  • FIG. 1 there is shown diagrammatically at 24 the system provided by the invention for ensuring the withdrawal and shifting of the lance when leaving the tube T having undergone the internal quenching and the external quenching.
  • the lance 22 is arranged so that the quenching liquid is injected into the bore of the tube T ⁇ in the direction of advancement of the latter through the overflow tank 14.
  • the tube T ⁇ through the overflow tank 14 there is a series of inclined rollers in the latter 10 ⁇ , similar to the outer rollers 10, and possibly upper guide rollers 20, to limit the risk of bending the tube.
  • the lower rollers 10, 10 ⁇ and the upper guide rollers 20 are covered with an appropriate coating making it possible to avoid marking the tubes.
  • the device further comprises a recovery channel 26 with settling tanks and filtration system 30 and purification 32.
  • the quenching liquid to be recycled is stored in a tank 34 from which a recovery and pressure recovery circuit 58 ensures on the one hand the low pressure supply of the overflow tank 14 and, on the other hand, the high pressure supply of the primary quenching rings 12a, 12b, 12c and 12d, of the inlet ring or rings 16, 38, 40 of the possible secondary rings 18 and of the lance 22.
  • a tube T supported by the guide rollers 10 is present at the entry of the primary quenching rings 12a, 12b, 12c, 12d, it passes through these rings and it obscures the system cell control provided at the inlet 52 of the overflow tank 14 which triggers the opening of the valve 36 and the commissioning of the high-pressure high-pressure inlet ring 16 (or similar rings 38, 40 in Figure 2).
  • the tube enters the tank 14 at a speed of between 1 and 3 m / sec.
  • the quenching liquid for example water
  • the internal quenching may be faster than the external quenching.
  • the invention provides for a clocked operation of the primary rings from downstream to upstream (from 12a to 12b, 12c and 12d) as the tube enters the tank 14.
  • the number of primary rings 12a, 12b, 12c and 12d is determined according to the most unfavorable case of internal quenching speed compared to the external quenching in the overflow tank 14.
  • the mixing blades, or the like, 28, provided in the overflow tank 14 improve the heat exchange and the quality of the quenching. Furthermore, the length of the tank 14 makes it possible to carry out a certain back and forth by turning the tube T ⁇ in the tank, which promotes the homogeneity of the quenching during the final phase thereof, once the tube has completely entered the overflow tank.
  • the tube can be removed: either by the inlet orifice 52 of the tank by bringing the tube T ⁇ back on the train of rollers 10 ⁇ , - either from above the tank 14, using handling arms or equivalent, - either by an outlet orifice 54 provided opposite the inlet orifice 52, after withdrawal of the lance 22 this outlet orifice 54 being provided with a shutter valve 56 similar to the valve 36.
