Definitions

  • the invention relates to a transport container for transporting molten metal of the type specified in the preamble of claim 1 and a refractory concrete lining for the delivery of a transport container.
  • Transport containers are known for the road transport of molten metals, such as liquid aluminum, which are constructed from an outer wall, insulation and an inner, fire-resistant concrete lining. In the course of the life cycle of such a transport container, the insulation and the refractory concrete lining are renewed several times. This process is known as delivery.
  • the refractory concrete lining is produced in that after the insulation has been introduced, formwork is introduced into the transport container and the space between the formwork and the insulation is poured out with liquid concrete. After the concrete has dried, the formwork is removed. For complete drying and for producing the ceramic bonds of the refractory concrete lining, the transport container is heated up according to a predetermined temperature curve before the first filling.
  • moisture-sensitive insulation materials are often used as insulation. These can be, for example, microporous insulation materials or high-temperature insulation panels made of aluminum silicate fiber mixtures.
  • the invention has for its object to provide a transport container of the generic type, the manufacture and delivery is simplified and which has an improved insulating effect or a thinner wall thickness compared to known transport containers.
  • Another object of the invention is to provide a refractory concrete lining for the delivery of a transport container.
  • the concrete lining from precast concrete parts.
  • the precast concrete parts have already hardened so that no moisture is brought into the transport container via the precast concrete parts. This will help in the Transport container water volume significantly reduced. No appreciable amount of water is preferably introduced via the concrete lining.
  • the precast concrete elements are preferably already annealed when they are placed in the transport container. By tempering the individual precast concrete parts in the precast plant, a very defined temperature curve can be achieved. This enables precast concrete parts with defined properties to be manufactured.
  • the properties of the precast concrete elements are independent of the furnace used for filling. Since the transport container is already lined with refractory precast concrete parts, the transport container no longer has to be heated up according to a defined temperature curve before use in order to produce the ceramic bonds in the concrete.
  • the transport container can also be quickly heated to operating temperature, since in contrast to the concrete poured into the transport container, no physically bound water has to be expelled. This significantly reduces the time until the transport container is put into operation and thus the time required for delivery.
  • the precast concrete elements are advantageously dimensioned such that they can be introduced into the transport container through an assembly opening in the transport container.
  • the precast concrete parts of the concrete lining are preferably connected to the insulation via chemically bound mortar.
  • the precast concrete parts are preferably glued to the insulation over the entire surface of the chemically bound mortar.
  • the mortar layer is advantageously a few millimeters, for example from 1 mm to 5 mm. Because chemically bound mortar is used to connect the precast concrete parts to the insulation, little or no moisture is introduced into the transport container via the mortar during heating, so that the penetration of moisture into the insulation can be reliably avoided. Because the transport container is lined with tempered precast concrete parts and chemically bound mortar and / or concrete, the moisture-sensitive container remains Insulation dry. In this way it can be achieved that the actually achieved, measured heat transfer values of the transport container correspond approximately to the theoretical heat transfer values and thus very good insulation is achieved.
  • Joints are advantageously formed between adjacent precast concrete parts.
  • the joints between the precast concrete elements are also preferably filled with chemically bound mortar. This is especially intended for narrow joints.
  • at least one joint is formed with at least one step in the cross-section in the direction perpendicular to the inner surface of the concrete lining.
  • the step is advantageously formed by overlapping, projecting sections of the adjacent prefabricated concrete parts.
  • the length of the projecting sections is advantageously at least 10 mm, in particular at least 20 mm.
  • the length of the projecting sections is advantageously significantly greater than the width of the joint. This advantageously results in an offset between the inside of the joint and the outside of the joint.
  • the outer wall of transport containers is subject to very large tolerances. Deviations of one or more centimeters are not uncommon here.
  • the insulation which is often applied by hand, is subject to large tolerances.
  • at least one joint for tolerance compensation is advantageously formed in the circumferential direction of the transport container.
  • the joint advantageously has a width of at least 10 mm, in particular at least 20 mm. Based on the nominal size of the transport container, the width of the joint can be, for example, in the range from 30 mm to 150 mm.
  • the gap for tolerance compensation is advantageous with backfilled with chemically bound concrete. This allows a comparatively wide joint to be filled well. Because the concrete is chemically bound, no or almost no water is released when the concrete sets, so that no appreciable amount of liquid is introduced into the transport container via the joint to compensate for tolerances.
  • the transport container advantageously has a pouring spout, which is poured in particular with chemically bound concrete. This means that little or no liquid is introduced into the transport container through the pouring spout.
  • the concrete lining for the delivery of a transport container, it is provided that the concrete lining comprises several precast concrete parts made of refractory concrete.
  • Fig. 1 shows a transport container 1, which is used for transporting molten metals such as liquid aluminum.
  • the transport container 1 has a container wall 2 which delimits a container interior.
  • An assembly opening 14 and a pouring spout 16 extend through the container wall 2.
  • the transport container 1 has a lid 11 which closes the assembly opening 14.
  • the transport container 1 can be redelivered via the assembly opening 14.
  • the lid 11 has a filling opening 15 which is closed during the transport of molten metal.
  • the filling opening 15 serves for filling metal melts to be transported.
  • the pouring spout 16 has a pouring opening 30, which is closed by a releasable closure cover 17 during the transport of molten metal and can be poured out of the transport container 1 through the molten metal.
  • the structure of the cover wall can advantageously correspond to the structure of the container wall 2. It can be provided that the transport container 1 is heated or kept warm, for example by means of a burner, through an opening, in particular
  • the container wall 2 is constructed in several layers.
  • the outside of the container wall 2 forms an outer wall 3, which is formed in particular from steel.
  • the inside of the outer wall 3 is insulated 4 ( Fig. 2 ) lined.
  • the insulation 4 is in Embodiment constructed by a layer of heat composite panels 5, which connect to the outer wall 3, a vapor barrier 6, a layer of insulation panels 7 and a further vapor barrier 8.
  • the thermal composite panels 5 can be, for example, high-temperature-resistant, microporous insulating materials.
  • the insulation boards 7 are in particular high-temperature insulation boards made of aluminum silicate fiber mixtures.
