  • ABSTRACT 52 us. 01 ..266/39, 105/265, 105 271
  • the refractory lined vessel is elongated and carried y 266/39 wheeled bogies to be tiltable about a horizontal axis, and in- [511 Int Cl czlc cludes the improvements, severally and in various combina- 58]
  • Field 34 R tions that the vessel shell is bulged and the lining is thickened opposite the opening, preferably over at least percent of 105/265 E the length of the vessel and about half of its peripheral extent,
  • VAN w/eR ST ATTORNEY CAR WITH A VESSEL FOR THE CONVEYING OF HOT SUBSTANCES, PARTICULARLY MOLTEN PIG IRON This invention relates to a car with a vessel for the conveying of hot materials, particularly molten pig iron, comprising at least two wheel bogies one behind the other in the conveying direction, the longitudinal vessel extending with its longitudinal axis in the same direction and having an outer shell internally lined with refractory bricks, which vessel is tiltable about its longitudinal axis, is supported by the bogies and is provided about in the center and, in the position for conveying, in the upper part thereof, with an opening.
  • the present invention aims at removing the objections of such known vessels and cars, which could bar the development of such vessels of larger volumes.
  • Another advantage of the invention consists in the fact that the outer shell of the vessel has the thickest heatinsulating layer in the zone where the thermal load of the lining is greatest. Thanks to the thicker insulating layer in this zone the temperature distribution in the bulged out part is more uniform, which gives an additional weapon against crushing and breaking out of refractory material.
  • a favorable amount of bulging out according to the invention is such that the largest bulge of the outer shell is about 7-9 percent of the transverse dimension or diameter of the vessel in this zone.
  • a bulging out is preferable which extends in the longitudinal direction over about 40 percent of the length of the vessel and which extends in the peripheral direction for about half the periphery thereof.
  • the refractory lining within the outer shell and also within the bulged out part thereof could have different shapes more or less adapted to the shape of the outer shell of the vessel.
  • a vessel according to the invention in such a way that the inner shape of the refractory lining consists of a cylinder coaxial to the tilting axis of the vessel, said cylinder being closed at its ends by frustoconical surfaces and is interrupted only in the zone of the opening in the vessel by a somewhat different shape.
  • the bulged out part is in this combination chosen so as to be shorter in length than the cylindrical part of the refractory lining.
  • Such a shape of the refractory lining is according to the invention best obtained by giving the bulged out part mainly the outer shape of a downwardly displaced half of a cylinder, having two shell parts joining this half cylinder in the longitudinal direction and merging into the non-bulged part of the outer lining, said two shell parts being substantially part-conical surfaces.
  • the invention also proposes as a further embodiment to give the lining such a pit or hollow already before putting the vessel into operation when making a new lining, such pit or hollow being positioned diametically opposite the filling opening.
  • This pit or hollow does already at the first filling of the vessel with the new lining fulfil the favorable function as described above for the pit or hollow.
  • FIG. 1 shows in longitudinal section and somewhat diagrammatically a car with a vessel according to the invention.
  • FIG. 2 is a cross-section according to the line II-Il in FIG. 1 on a larger scale.
  • numerals 1 and 2 show somewhat diagrammatically two wheel bogies each with 8 axes, the bogies having upper frames 3 and 4 for supporting the vessel.
  • the bogies and wheels could be of conventional structure, so that a detailed description thereof will not be necessary.
  • the frame structures 3 and 4 have buffer, coupling and drawing means at 5 and 6.
  • the frame structures have part-spherical concave supports.
  • Two frame plates 7 and 8, one to each side, are supported through convex part-spherical parts in supports 9 and 10.
  • On such frame plates 7 and 8 bearing the structures 1 l, l2, l3 and 14 all having the same horizontal axis are mounted.
  • In these bearings there are shaft trunnions l5 and 16, mounted rotatably therein and connected to the longitudinal ends of the longitudinal vessel 17.
  • Driving means 18 shown only diagrammatically and known and usual as such serve to tilt the vessel 17 when it has to be emptied.
  • Such means 18 could include an electric motor, an internal combustion engine or other prime mover, speed reducing means, feed and control means etc.
  • the vessel 17 is provided with an inner refractory brick lining extending between and including two plane end faces 20.
  • the brick lining merges from said faces 20 through conical parts 21 and 22 into a mainly cylindrical intermediary part 23, which is only interrupted and shaped differently in the zone of the filling opening 24.
  • the entire brick lining is surrounded by a metal outer shell. The splash shields protect this shell against local superheating by spilled liquid metal during filling and emptying of the vessel.
  • the central part of the vessel has in the lower half 26 of the outer shell the shape of a semicylinder, but this is displaced downwardly with respect to the remainder of the outer shell.
  • This part 26 through two shell parts 27 and 28 merges into the remainder of the outer shell.
  • These shell parts 27 and 28 each have substantially the shape of half a frustoconical body.
  • the inner shape of the refractory lining 19 does not follow this shape of the shell, but goes straight on as a cylindrical body, so that this lining in the central part is thicker than in other zones in the vessel 17. It is possible as shown in FIG 2 to make a pit or hollow 30 beforehand in the bottom of the lining immediately below the opening 24. The function thereof is explained amply above.
  • the vessel according to the invention could be applied for molten pig iron, as a mixer car and for conveying and/or desulphurizing thereof, but also for the conveying of many other very hot substances such as other molten metals.
  • a car with a vessel for the conveying of hot substances, in particular molten pig iron, comprising at least two wheel bogies one behind the other in the conveying direction, the longitudinal vessel extending with its longitudinal axis in the same irection and having an outer shell internally lined with refractory bricks, which vessel is tiltable about its longitudinal axis, is supported by the bogies and is provided about in the center and, in the position for conveying, in the upper part thereof, with an opening, characterized in that the outer shell has a shape diametrically opposite the opening, which is bulged outwardly as compared with the general shape of the remainder of the vessel, and that diametrically opposite the opening in the vessel a hollow or pit is present in the refractory lining.
  • An improved car for storing, conveying and dumping hot molten metal, the car comprising:
  • said car being improved in that:
  • said outer shell has a zone diametrically opposite said opening, which is outwardly deflected or bulged as compared with the general shape of the remainder of the vessel, and
  • said refractory lining has a thickness in said outwardly bulged zone only which is greater than its lining thickness in any other parts of said vessel.
  • said outwardly bulged zone extends longitudinally over about 40% of the vessel length, peripherally over about half the periphery thereof, and outwardly to a maximum depth of about 7 to 9 percent of the transverse dimension of the vessel at said zone.
  • said refractory lining has an internal surface which is substantially cylindrical and coaxial with the tilting axis of the vessel except at the region of said opening, and which is closed at its ends by frustoconical surfaces, and
  • said outwardly bulged zone is shorter in longitudinal extent than said cylindrical part of said internal surface.
  • An improved car for storing, conveying and dumping hot molten metal, the car comprising:
  • said car being improved in that:
  • said outer shell has a zone diametrically opposite said opening, which is outwardly bulged as compared with the general shape of the remainder of the vessel,
  • said refractory lining has a thickness in said outwardly bulged zone which is greater than its thickness in other parts of said vessel, and
  • said refractory lining diametrically opposite to said opening is formed with a hollow or pit therein.
