Definitions

  • the present invention relates to a support for a blast furnace probe which is introduced horizontally through an opening provided in the side wall of the blast furnace, this side wall consisting of a metal shield and an inner lining of refractory material comprising a block fixed on a flange provided for this purpose on the metal shielding, this block being provided with an axial bore to allow the passage of the probe.
  • These probes are intended to measure the temperature at various predetermined points inside the oven and to take gas samples for analysis. The result of these measurements and analyzes allows monitoring and control of the operation of the oven.
  • probes There are two different types of such probes. Some are arranged above the loading material and remain there permanently. The others are introduced into the loading material itself and are extracted again after the samples have been taken.
  • these probes In order to provide as complete and precise information as possible, these probes must penetrate into the region of the central axis of the furnace. Therefore, depending on the capacity of the oven, these probes must be up to eight meters in length and sometimes even more. This results in serious support problems which become all the more difficult as the probes are longer. Indeed, these probes are cantilevered with the only support point a flange provided on the metal shielding of the wall of the oven for the introduction of these probes. These are therefore exposed to the risk of deformation under the action of their own weight and under the action of the descent of the material inside the oven. In addition, the support point of the probe undergoes the reaction of these forces and stresses, reaction proportional to the moments exerted by the length of the probe overhang.
  • the object of the present invention is to provide a support for a probe which makes it possible to reduce the drawbacks and problems caused by the cantilevered suspension of the probe.
  • the present invention presents a support for a probe of the type described above, which has the features of claim 1.
  • the inner end of the lower support is provided with a hardfacing of a hard and refractory steel, that is to say having anti-abrasive and heat resistant characteristics. , on which the probe slides.
  • the present invention provides a probe whose support is offset towards the interior of the furnace, in comparison with the support of existing probes, which makes it possible to reduce in this way the length of the overhang.
  • the invention thus makes it possible to gain approximately 80-100 cm, which, taking into account the fact that the length of overhang intervenes at the third power for the determination of the deformations, constitutes a non-negligible progress.
  • the deflection resulting from the self-weight of the probe is reduced, for a reduction of 5 to 4 meters from the overhang, to i.e. 40% of the deflection of a 5 m overhang.
  • the lower support of the probe is preferably in the form of a trough whose curvature corresponds to that of the bore of the support block.
  • a circulation of cooling water is provided through the lower support and the block of the support.
  • FIG. 1 schematically shows a probe 10 in the measurement position introduced into the loading material of a furnace, the wall of which is constituted by an external metal shield 12 and an interior refractory lining 14.
  • This probe 10 is introduced through an opening 18 provided in the shield 12 and the refractory lining 14.
  • the shield 12 is provided with a flange 20 around this opening 18 for fixing a support 22 according to the present invention.
  • On the support 22 is located, on the outside, a valve 16 known per se, intended to close the opening abandoned after the extraction of the probe 10 from the oven.
  • the support 22 proposed by the invention essentially comprises a block 24 occupying the space delimited by the flange 20 of the shielding 12, and a support 26 extending in the opening 18 at least that beyond half the thickness of the refractory lining 14.
  • the block 22 is fixed, in a manner known per se, for example by means of bolts not shown on the flange 20.
  • the block 24 has a central bore 30 whose diameter is slightly greater than that of the probe 10 to allow passage of the latter.
  • This bore 30 is extended, in part, by the support 26, the upper face of which is in the shape of a trough, with a curvature corresponding to that of the bore 30.
  • On the inner end of the support 26 is provided a reloading 28 of hard and refractory steel on which the probe 10 rests and slides.
  • the reloading 28 formed by this weld constitutes the only lower support of the probe 10 and determines the length "L" of the probe overhang.
  • a second support 32 On the outer side at a distance cl "from the reloading 28 is a second support 32 which is an upper support.
  • the support 22 proposed by the invention has made it possible to increase the length "I” in favor of the length "L” and by modifying the ratio "f", the invention allows a significant reduction in the reactions at the two support points 28 and 32.
  • the support 22 is provided with an inlet 34 and an outlet 36 for the circulation of a coolant.
  • the body of the block 24 and of the support 26 are hollow and the coolant is brought directly from the inlet 34 to the inner end of the support 26 from which it returns to the hollow from block 24 to exit through orifice 36.
  • the support 22 includes an inlet orifice 38 designed to be connected to a pressure air line not shown and opening into a circular chamber 40 communicating by a circular slot 42 with the bore 30.
