Definitions

  • the invention relates to a vessel for receiving a molten metal.
  • the invention includes all sizes and geometries of such vessels and regardless of the type of molten metal.
  • the US 5,499,798 A shows such a vessel with a refractory lining of stones, which have a trapezoidal shape in vertical section.
  • a vessel of the generic type for example a ladle, essentially has a pot shape and, correspondingly, a bottom from which, in the axial direction of the vessel, away from the ground, an endless wall extends on the circumference.
  • the vessel has approximately a cylindrical shape, wherein in the functional position of the vessel, the upper end is open or can be covered with a lid.
  • the axial direction of such a pan is defined below as the z-direction.
  • a copper converter as he from the EP 2253916 B1 is known and has the shape of a horizontal cylinder is the z-direction in the functional position of the converter horizontally.
  • the copper converter can be closed at both ends with a removable cover.
  • Terminology is defined as a lid as a bottom and a lid as the opening portion of this metallurgical vessel.
  • the wall of such vessels on the outside comprises a metal shell and inside a refractory ceramic lining.
  • the lining may be monolithic or consist entirely or in sections of bricks.
  • the stones are often laid in stone composite, with juxtaposed stones complement each other to form a ring.
  • a slag layer is present on the molten metal bath which is particularly aggressive towards the adjacent refractory lining.
  • the thickness of the slag layer determines the so-called slag zone.
  • This area of the lining must be adequately stabilized so that when the vessel (the refractory lining) heats up and cools down in that area no stress cracks or joints between the stones form, which can lead to molten metal infiltration and thus to the destruction of the refractory material.
  • the metal sheet thus serves as an "abutment", which counteracts expansion of the refractory material in the axial direction of the vessel.
  • the stability of such a sheet metal abutment is much too small to compensate for the thermal expansion of the refractory material.
  • the refractory material pushes the metallic cover upwards. There are further cracks in the refractory material. As a result, the refractory lining loses its stability and joints open. Melt infiltrates and reduces the durability of the lining.
  • the invention is accordingly based on the object to offer a way to more effectively compensate for thermal expansion in the refractory lining of a metallurgical melting vessel.
  • an area below and above the slag zone is to be optimized.
  • the stability of the lining should be improved. Maintenance work on the refractory lining is to be simplified.
  • the invention is based on the following idea:
  • the thermal expansion of the refractory lining of the vessel can not be avoided. It is given material / physical. Accordingly, other measures must be taken to compensate for the strain.
  • the invention is based on the idea, in the upper part of the refractory lining, ie adjacent the opening of the vessel (in the case of a copper converter, the opening corresponding to the lid area), at least one row of stones of the refractory lining "movable" form.
  • the directions refer to a normal state of the vessel, in which the soil is horizontal.
  • the juxtaposed bricks complementary to a ring section or ring can "wander" in and out as the refractory lining bricks or underlying monolithic lining expands under thermal load.
  • This flexibility requires a corresponding geometry of the stones, but also a distance of adjacent stones in the original state, to take into account the "conicity" of the stones, due to the approximate cylindrical shape of the vessel.
  • the bricks of the refractory lining are narrower on the inside than on the outside, in each case viewed in the circumferential direction of the metallurgical vessel or its refractory lining.
  • adjacent stones In order to the stones can move inwards (radially inwards) adjacent stones must first have a distance from each other, which decreases with increasing displacement in the X direction.
  • the size of the gap depends on the thermal expansion behavior of the refractory lining and the usual operating temperatures. It can be determined mathematically without further ado.
  • the invention then relates to a vessel for receiving a molten metal with the features of claim 1.
  • ring includes - as stated - also individual ring sections. For example, in vessels which have a laterally outwardly leading outlet zone at the upper free end of the wall, the ring will not be closed, but at least have an interruption.
  • the inclined surface of the stones indicates the direction of movement of the stones (inwards, upwards), wherein said stopper forms a corresponding abutment.
  • This stop is therefore stationary and fixed, for example, on the outer metal shell of the vessel.
  • the stop can be materially connected to the metal shell.
  • the stop may be triangular or trapezoidal in cross section. In both cases, the desired inclined surface is formed.
  • the angle of the inclined surface of the stones or the angle of the stop surface varies depending on the type of vessel and the local conditions of use.
  • the abutment surface of the abutment extends at an angle between 5 and 60 ° to the axial direction of the vessel, wherein the axial direction of the vessel is a direction which is substantially perpendicular to the bottom.
  • the angle of the inclined surface of the stones of the first ring can be specified between 30 and 85 °, with respect to a plane which is perpendicular to the axial direction of the vessel.
  • the angle of the abutment surface will be between 30 and 50 °, that of the inclined surface of the stones between 60 and 40 °.
  • An insulating layer may be provided at least in sections between the refractory lining and the metal jacket.
  • the stones of the first ring - in the X direction - may be formed longer than the other stones of the lining, so that they can rest directly on the outside of the metal sheath (in the starting position, that is, when re-delivery or after a repair).
  • the stones of the first ring are preferably laid dry.
  • the distance between adjacent stones (between corresponding faces of adjacent stones) of the first ring may also be filled with a compressible or combustible material (grout).
  • grout compressible or combustible material
  • the selection of the joint material is such that it is ensured that the stones have a thermal expansion of the adjacent refractory material a free mobility in the X and Z directions.
  • Suitable joint materials are: fiber insulation, cardboard, bitumen fleece, foamed plastics. Likewise, an air gap is possible.
  • the stones of the first ring are pressed and fired products.
  • the stones are made of a high quality grade, for example, a magnesia-chromite offset.
  • this ring or rings then be arranged at a distance to the first ring and at a distance to the bottom of the vessel.
  • Such other rings are also made of stone formats, as they were described for the first ring and analogously outside of these stones then each a corresponding stop (as described above) is arranged, which serves as an abutment for the moving stones within the ring.
  • the invention can be advantageously realized for a metallurgical ladle, but also for other vessels, in particular those vessels which have at least one bottom and a substantially cylindrical wall (eg converter).
  • the stop (the abutment) can be cooled to reduce thermal expansion.
  • the stop can be connected to a coolant circuit.
  • FIG. 1 a ladle is shown having a bottom B and a substantially cylindrical wall W extending upwardly from the bottom B and defining an opening O at the top free end.
  • the vessel (the ladle) has an outer metal shell M in the wall and floor area.
  • a refractory ceramic lining A connects, wherein in the wall region between refractory bricks S of the lining A and the metal shell M two insulating layers I run.
  • the upper end of the vessel wall W is also referred to as a gas area (freeboard).
  • a first ring R1 of refractory bricks 10 is provided in this area, which are assembled side by side to form the first ring R1 and define the opening O of the vessel accordingly.
  • adjacent stones 10 of the first ring R1 are spaced from each other and this distance is filled with a bitumen nonwoven 14, which softens at temperatures above 200 ° C and then burned almost residue-free.
  • the stones 10 of the ring R1 are on their rear side, the metal shell M adjacent, each formed with an inclined surface 10s, which extends at an angle ⁇ of 45 ° to the horizontal.
  • the stones 10 are with their inclined surface 10s against a corresponding stop surface 20a of a stopper 20, which extends radially outward, behind the stones 10 and is secured to the metal shell M.
  • the inner surfaces of the bricks S of the liner A and the bricks 10 of the ring R1 are substantially aligned with each other, as in FIG FIG. 2 shown on the left.
  • the refractory lining A heats up accordingly and the stones S expand in the direction Z (right part of FIG. 2 ).
  • the standing under axial pressure (in the direction Z) stones 10 within the ring R1 are accordingly pushed upwards (in the direction Z), ie against the stop surface 20a of the stopper 20.
  • the stones 20 according to the invention with their inclined surfaces 10s along the stop surfaces 20a slide, both towards the interior of the metallurgical vessel (in the direction X) and in the direction Z, as in the right part of FIG. 2 shown schematically (supernatants X1, Z1).
  • a second ring R2 made of refractory bricks 12 is arranged below the ring R1, and a further stop 22 is correspondingly arranged.
  • the above statements on the ring R1 and the degrees of freedom of the bricks 10 apply correspondingly to the ring R2 and the degrees of freedom of the bricks 12.
  • the displacement paths of the stones 12 are indicated by X2, Z2.
  • FIG. 2 also shows a coolant port K in the region of the stop 10 to cool the stop 10 during operation and to reduce thermal expansion.
