Definitions

  • the invention relates to a pan for receiving and possibly post-treating and / or transporting 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 firebricks or the like, which lie the floor next to one another and cover the side walls of the pan.
  • 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 up before the remaining parts of the pan bottom are worn out.
  • the object of the invention is to prevent the premature wear at the point of impact of the pouring jet and thereby to increase the service life of the pan with simple and inexpensive means.
  • a projection element is inserted into the lining at the point of impact of the pouring jet, which protrudes beyond the surface of the lining with a projection surface that merges into the surface of the adjacent lining without a step and whose diameter is larger than the diameter of the pouring jet.
  • This configuration has the advantage that the pouring jet is struck across the hump surface without significant swirling of the liquid metal when it hits the hump element and flows at its edges with essentially laminar flow onto the remaining surface of the adjacent brick lining.
  • 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 humped surface can be spherical, pyramid-shaped or in the manner of a cross-vaulted 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 top with a lid 12 which has a pouring opening 13.
  • 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 hump stone 20 can, depending on the type of lining 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 useful if the pan 10 has a circular plan and the impact point 18 of the pouring jet 19 is approximately at the point where the floor lining 17 merges into the side wall lining 16.
  • hump stones according to the invention are shown, which can be made for example from chamotte or from 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 merges into concave edge parts 22f, 22g, 22h and 22i.
  • 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 designed as a cross-vaulted surface.
  • 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 on the lower edge of the pan and pulled up with its hump surface on the edge of the pan be when 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 into the surface of the brick lining on all sides, so that the pouring stream does not find any steps or projections.
