Definitions
- Liquid metal in particular liquid aluminum, treatment system,
- the present invention relates to a method for adjusting predetermined melt properties in liquid metal, in particular liquid aluminum, a treatment system, a transport container and a transport vehicle for liquid metal.
- liquid metal This molten metal is also referred to below as liquid metal.
- insulated containers were developed that can be transported on truck trailers. Depending on the model, around 13 to 20 tons of liquid metal can currently be delivered by truck.
- the metal is filled in the melting plant in the transport container with up to 950 0 C.
- the filling temperature can not be exceeded for metallurgical reasons.
- the delivery temperature is set for each foundry.
- the theoretical maximum transport path results from the temperature difference between filling and delivery as well as the hourly temperature loss.
- the practical transport route is significantly shorter, since for safety reasons the metal must be so hot when it is delivered to the foundry that if the refusal is refused (for whatever reason) the metal is still liquid, if the truck picks up the unapproved containers the aluminum smelting plant has transported back.
- the distance between the smelting plant and the foundry is four hours of trucking, which at a mean speed of 75 km / h results in a distance of around 300 km.
- the invention is therefore based on the object that, irrespective of the duration of the transport time of liquid metal, in particular liquid light metal alloys, the liquid metal with the desired properties at the customer, that is especially in a foundry, can be made available for further processing.
- the invention is based on the finding that this object can be achieved by the container, which is used for the transport of the liquid metal, simultaneously serves for the treatment of the liquid metal.
- the object is therefore achieved by a method for setting desired melt properties in a liquid metal, in particular liquid aluminum, wherein at least one melt property after filling a transport container, during transport of the transport container, after transporting the transport container to a further processing in the transport container and / or when emptying the transport container is set.
- melt properties are understood in the context of this invention, chemical and physical properties.
- melt properties after filling a transport container By adjusting the melt properties after filling a transport container, they can be adapted to the conditions during transport. Changes that result from the filling in the transport container or due to the transport, therefore no longer need to be considered before bottling. Thus, overheating of the melt to ensure a delivery temperature, as is necessary in the prior art, not required. In addition, an additional treatment space for the melt is created in the treatment of the melt in the transport container. A smelting furnace or holding furnace, in which the melt is in the manufacturing process prior to filling, can therefore be made available faster for new batches.
- the transport of the transport container during which at least temporarily the adjustment of the properties takes place the entire period of time from filling the transport container to the complete emptying of the transport container.
- the transport may include storage in the smelting plant after filling, the journey by which the transport container is transported to the further processing site, for example foundry, and optionally storage at the destination.
- the setting of the properties can be done immediately after filling the transport container. This is the case, for example, in the smelter in which the melt was produced. However, it is also possible according to the invention that the setting of the properties takes place during the actual transport of the transport container, that is to say the drive.
- the transport of the smelting plant that is, the manufacturing and bottling of the melt to the further processing plant, in particular a foundry referred to. These sites are usually far apart and can last for several hours, for example more than 2 or 3 hours. Since according to the invention, the adjustment of the properties can also be done while driving, such a long transport time is possible without having a negative effect on the properties of the molten metal at the destination.
- the treatment of the liquid metal after delivery still in the transport container has the advantage that the melt does not have to be directly their actual destination, such as mold, fed, or must be transferred to storage containers. This has for the customer on the one hand the advantage that the design effort and workload can be kept low. In addition, the properties of the molten metal are not adversely affected, which could be the case with a new refilling.
- the setting of the properties can be continued or carried out during the emptying process of the transport container.
- this treatment of the molten metal it is possible to remove the molten metal in small batches from the transport container and still be able to ensure the desired properties until complete emptying.
- the adjustment of the properties in all the above-mentioned phases be performed between the filling of the transport container and the complete emptying of the transport container, the adjustment may also be restricted to individual phases.
- a setting of the properties can only be done while driving.
- a Such an embodiment is suitable, for example, when the molten metal is transported away from the filling site immediately after filling and is supplied directly or at least in a timely manner after arrival at the destination of further processing.
- the adjustment of the melt properties relates in particular to the maintenance of properties of the molten metal.
- the maintenance is achieved by active measures.
- the maintenance of properties can be carried out with relatively simple means and, in particular, be carried out in a transport container, both in terms of its capacity and in terms of accessibility is limited to the molten metal.
- the temperature of the liquid metal is maintained during at least one of the above-mentioned phases of the transport.
- the transport time can be extended, which is not possible with a pure isolation of a transport container.
- overheating of the molten metal prior to filling is not necessary and thus it is also possible to transport alloys whose critical temperature is only insignificantly above the transport temperature.
- heating devices can be dispensed with and energy can thus continue to be saved.
- the homogeneity of the molten metal can also be maintained according to the invention. This can be done by mixing the molten metal present in the transport container. By mixing in addition to the distribution of alloying elements and the distribution of the temperature can be homogenized. This has the advantage that the melt located in the transport container can be taken at the destination in individual batches, without resulting in quality or temperature differences.
- a treatment device in particular the effective part of the treatment device, for example the heatable area of a heating device, is introduced into the melt.
- the introduction of the melt is understood to mean the movement after the end of which the treatment device is located at least partially below the surface of the molten metal.
- the introduction of the treatment device into the liquid metal is advantageous if the treatment is to be carried out while driving.
- the transport container When transporting the transport container on roads or rails, it may cause changes in the surface of the liquid metal due to uneven floors, in particular, this can increase or decrease on one side.
- treatment devices which are provided above the surface, the leads this leads to a change in the treatment conditions and, for example, to a local overheating of the liquid metal.

By this regional control, for example, a partial emptying of the transport container at the destination or a Minderglallüllung in the filling or a movement of the liquid metal while driving be taken into account. The area that is driven in the latter cases is preferably the area that is in the melt.
