Description

The present invention relates to a container for

  port having a multilayer, insulating and refractory lining

  in the case of heated and liquid metals, in particular non-ferrous metals such as aluminum or the like, which are transported by means of a truck, the receptacles being

closed during transport.

  With such containers, a liquid metal is trans-

  carried using the truck from the place of liquefaction of the metal to the place of use of the metal. During this time, a lowering of the temperature due to heat loss can not be avoided. However, the liquid metal must reach the place of use at a certain temperature. In order for the product to reach the desired temperature at the place of use, for example, in the case of liquid aluminum, the filling temperature is increased. So for liquid aluminum, it is necessary to have a temperature of 700 C at the place of use. To guarantee this temperature at all times, the metal being in the liquefaction place

  is introduced into the transport container at a temperature of

  much higher, for example at 900 C, so as to com-

  think of natural thermal loss.

  However, we can not avoid sometimes an increase in the duration of transport by truck. This can be caused for example by congestion in traffic, accidents

  on the road, damage to the tires of the vehicle

  transportation or also weather conditions

  encountered on the road. The driver of the transport vehicle

  port can not act against these disturbing influences.

  batrices. It can not therefore prevent the metal to be transported from cooling sufficiently so that, upon arrival at the place of use, its temperature

  is less than the desired value.

  The object of the invention is to guarantee, for a container

  of the type defined above, that the transporting metal

  in any case, the desired temperature at the place of use.

  This problem is solved by the fact that it is intended

2 2559137

  an insulation layer placed approximately in the middle of the lining, an electrical layer which is placed along the entire periphery of the container and which is fed with

  by a generator powered by the truck, the

  of the electrical layer being connected by means of

  Conductors of electrical connection with the generator.

  Thanks to the means according to the invention, the lining layer is heated by the electric ply heating device acting sufficiently to that so

  the natural heat losses are practically complete.

  compensated and to prevent a drop in

liquid metal to be transported.

  The advantage of the invention is that liquid metal can be transported also over distances

  quite long and therefore for quite a long time.

  This is particularly advantageous because such vehicles

  Transport vehicles should only travel at a very low speed. Other features and advantages of the invention

  will be highlighted in the following description,

  given by way of non-limiting example, with reference to the accompanying drawing in which: Figure 1 is a section of the transport container and the corresponding truck,

  FIG. 2 is a section on an enlarged scale of the

  veloppe of the container with the lining (detail A of Figure 1) A transport container 1 provided with a lid 2 and a lid lining 3 is mounted by means of a bracket 4 on the platform 6 lowered from a transport vehicle 5 provided with a running chassis 7. The part

  transport vehicle engine was not shown.

  The container 1 comprises an envelope 8 which is provided

  a refractory multilayer interior lining-18.

  The lining 18 consists of an insulating inner layer 10 of refractory concrete, which is covered on both sides by thin insulating layers 9 and 16. On the inner insulating layer 16 is arranged a layer of

3 2559137

  refractory concrete 17 resistant to wear.

  The heating device consists of an electric

  11, which is inserted into the refractory concrete layer

  The ends of the ply 11 are connected to electrical connection conductors 12 and 14 which terminate in a generator 13. The generator 13 is driven by means of a drive mechanism 15 by the truck motor, not shown, and thus the electric sheet It is supplied by the current required for heating the lining 18.

  The surface of the road surface is represented by 19.

  The insulating inner layer 10 can also be made

  sée with light refractory bricks.

  Of course, it is possible according to the case, to provide that the platform 6, possibly lowered, the truck comprises several containers 1, arranged for example one

  behind the other in the direction of the vehicle.

  It goes without saying that without departing from the scope of the invention,

  Many modifications can be made to the reci-

  refractory liquid metal transport pellet, described and shown. For example, the transport vehicle can

  be the platform of a wagon or semi-trailer.
