Definitions

  • the invention relates to an open and closed metal container for keeping warm and Melting metals and their liquid metal transport in the preamble of the claim 1 required Art.
  • Movable and firmly molded crucibles are used to keep and melt metals for use.
  • Movable crucibles are made of, for example, clay graphite, silicon carbide, cast iron, cast steel or sheet steel depending on the casting materials to be kept warm or to be melted. You will be in Holding or melting furnaces are used. The heating can be done by electrical resistance, Induction or gas. The heat is transferred to the one in the crucible liquid or solid metal over the furnace space or with induction directly through the crucible wall instead, resulting in significant wear and tear due to thermal, mechanical and chemical stress the crucible used leads. Also in particular with electrical resistance or Gas heating requires a lot of energy to heat the furnace space, the crucible as also necessary due to the heat loss of the furnace refractory lining.
  • EP 0 895 490 B1 and DE 198 02 342 C1 describe one Crucible furnace for the low pressure casting process or for filling the pressure chamber of a horizontal and vertical cold chamber die casting machine.
  • Firmly molded crucibles form an integral part of the furnace. They usually consist of one Firebrick masonry with a stamped or cast refractory lining. Due to the masonry thickness, the liquid metal is heated in the furnace via an induction channel.
  • a major disadvantage here is that the induction trough is particularly useful for aluminum alloys depending on the metal throughput already after approx. 2 weeks through sticking oxides and Nitrides can block the metal flow.
  • To open the induction trough the Casting furnace replaced, the residual melt removed and the induction channel using a jackhammer be opened again.
  • the furnace outer jacket temperatures are also at 70-100 ° C and in the induction channel area at up to 120 ° C. This closed furnace system is mainly used for the low pressure casting process.
  • the invention has the object: one open and closed metal containers for keeping warm, melting and liquid metal transport of metals, which according to the previous definitions is neither a movable one still has a fixed crucible.
  • the open and closed metal container a housing is formed, in the interior of which thermal insulation materials are open or form closed cavity, which is lined with a textile fabric and the closed metal container has a movable furnace riser.
  • the open and closed metal container designed according to the invention can be in the open Execution as a holding, scooping and melting furnace can be used with the closed Execution as a holding furnace, low pressure casting furnace, low pressure metal conveyor furnace and as Liquid metal transport container can be used.
  • the open and closed metal container according to the invention has a one-piece, textile Fabric that holds the open and closed cavity of the metal container of liquid or solid metal as well as pouring channels and top surfaces and covers. This is achieved through the high flexibility of the textile fabric as well their diverse geometric and spatial design options. It can one-piece, textile fabrics one or more layers for lining and covering Cavities and surfaces are used. Over coatings of single or multi-layer Surfaces of the textile fabric, depending on the requirements of the used liquid or solid metals, their thermal, chemical and mechanical Properties additionally increased. become. In a further advantageous training, the The jacket and bottom surface of the textile fabric surrounding thermal insulation material as a seamless insulation housing open at the top.
  • the one-piece, movable furnace riser attached to the closed metal container becomes passed through a bushing and centered.
  • the one detachably connected to the furnace riser Actuator enables the opening and closing processes of an endlessly continuous Liquid metal filling of metallic and non-metallic casting molds as well as the filling of pressure chambers.
  • the closed metal container for the Liquid metal transport additionally from a lockable single or collective container added.
  • the open metal container 1a in Fig. 1 has an opening formed by the fabric 4 opening 12, which is also used for filling the cavity 11 with liquid and solid metals as for the removal of liquid metal for the casting process.
  • the heating for keeping warm and melting of liquid and solid metals can be done by heating elements 6, 7, 8 or induction 9 .
  • the open metal container 1a can thus be used as a holding, scooping and melting furnace in the casting operation.
  • FIG. 1 Another open metal container 1c for melting metals with a pouring spout 13 for the liquid metal and an inductive heating 10 is shown in FIG.
  • the movable furnace riser pipe 20 is guided and centered over the bushing 21 fastened on the furnace cover 16 .
  • This advantageous design enables the furnace used in the casting operation to be changed quickly and easily.
  • the liquid metal can be heated by heating elements 6, 7, 8 or induction 9 .
  • the closed metal container 1b can thus be used as a low-pressure casting furnace or low-pressure metal conveying furnace for filling casting molds or pressure chambers for the pressure casting process and for keeping metals warm in the casting operation.
  • FIG. 4 shows another closed metal container 1d for the liquid metal transport in a lockable individual or collecting container 28 .
  • the heat-insulating material 3f of the transport container cover 25 lining the interior is designed with a cone immersed in the liquid metal.
  • the closed metal container 1d can be used directly as a holding furnace for metal buffering in the casting plants as well as by changing the furnace lid or removing it as a holding, scooping, melting furnace, low-pressure casting furnace and as a low-pressure metal conveyor furnace, the heating of the liquid metal by insertable heating elements 6, 7 or by means of previously installed heating elements 8 or induction 9 .
  • the open and closed metal container 1a, 1b, 1c, 1d according to the invention can be produced in all spatial forms, the outer jacket 2 forming the interior, which is an open one via heat insulation materials 3, 3a, 3b, 3c, 3e, 3f and the textile fabric 4 and forms closed cavity 11 which receives the liquid or solid metal for keeping warm or melting and for liquid metal transport.
  • the high flexibility and rice strength of the textile fabric 4 enables the seamless lining of the cavity 11, the pouring spout 13 and the top surfaces 2 ', 3', 3a ', pins 14 or solid pins 15 fixing the textile fabric 4 in its position. Since the liquid metal can be emptied from the open metal container 1a, 1c or the metal container 1b, 1d to be opened, the change of the textile fabric 4 can be carried out at short notice.
  • Another advantage of the textile fabric 4 is its collapsibility and its low weight, which means considerable advantages for its storage and transport. Due to the high thermal stability of the textile sheet 4 , preheating times or slow heating times of the open and closed metal containers 1a, 1b, 1c, 1d are not necessary.
