Definitions

  • the invention relates to a pan for receiving and possibly post-treatment and / or transport of hot, liquid metals which are poured into the pan from an upstream melting unit, with a lining made of high-temperature resistant material, such as. B. firebricks that lie side by side cover the bottom and the side walls of the pan and have an impact element at the point of impact of the pouring jet, which protrudes beyond the adjacent surface of the lining.
  • a lining made of high-temperature resistant material, such as. B. firebricks that lie side by side cover the bottom and the side walls of the pan and have an impact element at the point of impact of the pouring jet, which protrudes beyond the adjacent surface of the lining.
  • Pans for liquid metals are used not only for transport, but also as reaction vessels for post-treatment of the metals. They are therefore closed with a lid that has only a moderately large opening through which the liquid metal from the melting unit is poured into the pan.
  • the pouring jet always hits the bottom of the pan at the same point, which places more stress on this point of impact than the other areas of the floor lining.
  • the floor lining at the point of impact of the pouring jet is destroyed earlier and to a greater extent than in the rest of the area.
  • the pan In the event of advanced wear and tear at the point of impact of the pouring jet, the pan must therefore be taken out of operation and re-bricked before the remaining parts of the pan base are worn out.
  • torpedo pans In order to take into account the wear of the lining at the point of impact of the pouring jet, it is known in torpedo pans to reinforce the lining by using thicker stones in the impact area of the pouring jet (DE-PS-31 14 069).
  • the lining must also be here adapted to the curved bottom of the torpedo pan and therefore bricked from several smaller stones, between which there are joints in which the impinging pouring jet can begin its work of destruction. Due to the concave design of the torpedo pan and its lining, there is also considerable turbulence in the area of the impact point, which leads to premature destruction of the lining at this point.
  • the object of the invention is to spread the pouring jet when it hits the bottom of the pan without significant turbulence and to design the impact point in such a way that premature wear of the lining is prevented at this point.
  • the impact element is a hump element inserted into the lining, the hump surface directed against the pouring jet merging into the surface of the adjacent lining without a step and the smallest diameter or smallest side length of which is larger at the transition to this surface than the diameter of the pouring jet at the point of impact.
  • This configuration ensures that the pouring jet, when it strikes the pan base, is spread by the hump element without any significant swirling of the liquid metal over the hump surface and flows at the edges thereof with an essentially laminar flow onto the remaining surface of the adjacent brick lining, into which the hump element passes without paragraph.
  • the hump element is expediently a monolithic hump stone, which takes up about a sixth to a quarter of the surface of the floor lining. As a result, there is no joint in the area of the entire impact point at which the metal flowing down with high energy could attack.
  • the hump element can have differently shaped hump surfaces.
  • the hump surface can be spherical, pyramid-shaped or in the manner of a cross-vault surface. It is particularly expedient if the hump surface has a central, convex part which merges into concave edge parts which connect tangentially to the surrounding surface of the lining. The entire deflection of the direction of movement then takes place in the area of the hump element.
  • the hump element can be arranged more in the middle or on the edge of the pan. In the latter case, it is expedient if an edge of the base part of the hump element, which is inserted into the lining, is adapted to the curvature of the side wall lining.
  • 10 denotes a pan for the aftertreatment and transportation of liquid metals, for example liquid steel, which consists of a container 11 made of steel or cast steel, which is covered on its upper side with a lid 12, which has a pouring opening 13 having.
  • the container 11 is provided with a lining 14 made of high-temperature-resistant refractory bricks 15, which are arranged in an association and form the side wall lining 16 and the bottom lining 17 of the pan.
  • a hump element 20 is inserted into the floor lining 17, which is designed as a monolithic hump stone and also consists of a high-temperature resistant material.
  • the humpstone is significantly larger in plan than the individual firebricks 15 of the floor lining 17, but its base part 21 has the same height h as the firebricks.
  • the hump stone has a hump surface 22 which protrudes beyond the surface 23 of the adjacent floor brick 17 and merges into the adjacent wall 17 at the edges 24 of the hump stone 20.
  • the smallest diameter D of the hump stone 20 or the smallest side length of the cross section at the transition to the surface 23 is substantially larger than the diameter d of the pouring jet 19 at the point of impact of the pouring jet.
  • the hump stone 20 can, depending on the type of brickwork 14, have different floor plans. It can be circular, square, rectangular or also designed such that one of the edges 24 of the base part 21 is adapted to the curvature of the side wall lining 16. This is expedient if the pan 10 has a circular outline and the point of impact 18 of the pouring jet 19 lies approximately at the point where the floor lining 17 merges into the side wall lining 16.
  • 3 to 10 show various embodiments of hump stones according to the invention, which can be made, for example, of chamotte or also of a high-temperature-resistant hard rock.
  • the hump stone shown in FIGS. 3 and 4 has a curved hump surface 22, which has an approximately spherical shape in the middle, but changes to straight edges after the edges 24, so that there is no shoulder in the middle of the edges 24 either.
  • the hump surface 22 is formed by a flat, four-sided pyramid which rises above the base part 21.
  • the hump surface 22 has the shape of a cross-arch surface, the four arch surfaces 22a, 22b, 22c and 22d of which meet in a tip 25.
  • the hump surface 22 has a central, convex part 22e which is divided into concave edge parts 22f. 22g, 22h and 22i passes.
  • the base part 21 has the same height h at every point of the stone, which corresponds to the thickness of the lining. All edges 24 of the hump stone are therefore in the same plane as the surface 23 of the floor lining 17, regardless of the manner in which the hump surface 22 is designed, whether it is spherical, pyramid-shaped or convex-concave curved or as a cross-vaulted surface che is trained.
  • the monolithic hump stone takes up about a sixth to a quarter of the surface of the floor lining.
  • the size of the hump stone depends on the height of the pouring jet and the amount of steel per unit of time that is poured into the pan.
  • the hump stone 20 can also be arranged at the lower edge of the pan and its hump surface can be raised at the edge of the pan if the point of impact lies on the inner edge between the floor lining 17 and the side wall lining 14.
  • Other configurations of the hump surface are also possible. It is essential, however, that the hump surface rises above the surface of the adjacent brick lining and that there is a continuous transition to the surface of the brick lining on all sides, so that the pouring stream does not find any steps or projections.
