Definitions
- the invention relates to a device for metering and transporting metal melts, consisting of a gas-tight container with inlet and outlet, with which melt is removed from a melt container or holding furnace or vice versa, from which melt can be conveyed.
- GB-A-1 100475 has disclosed a device in which liquid metal is conveyed from a dense and heated storage vessel by means of gas pressure through an overflow pipe into an open vessel, from which the liquid metal is used either for the continuous supply of continuous casting equipment or intermittently Filled forms given off. Controlled dispensing is achieved by opening or closing a pouring opening on the bottom with a stopper. As a result, metered quantities of liquid metal can only be poured off with limited accuracy.
- a pressurized gas-operated dosing device for liquids, in particular liquid metals, aggressive acids and alkalis which consists of a sealed collecting container with an inlet pipe, the inlet pipe in the form of an angle lifter or an outlet on the side or bottom of a melting tank leads to a container serving as a metering device, which is provided with a weighing device, wherein different gas pressures for transporting the liquid from the melting container into the metering container and upon reaching the desired amount in the metering container to interrupt the flow can be set in the containers.
- the metering device mentioned has the disadvantage that the metering container is firmly connected to the melting tank through the inlet pipe or the outlet, and that it is therefore not possible to transport the metering tank with the precisely determined amount of the melt contained therein.
- the present invention is therefore based on the object of providing a device for metering of the type mentioned at the outset, which not only allows the metering process to be carried out by simple manipulations, but also with which precisely metered melt can be transported and transported to other locations, with filling and dosing operations can be carried out sequentially in a rational manner.
- a device for metering and transporting metal melts of the type mentioned at the outset consisting of a gas-tight container with inlet and outlet, with which melt is removed from a melt container or holding furnace, or vice versa, from which melt is conveyed into a molten bath
- the inlet is at the same time the outlet of the container and the common inlet / outlet can be connected to a pipe system located in the melting container, such that the container by tipping or applying an overpressure in the container All or part of the melt is conveyed out of the container and during the filling process of the container the melt can no longer flow back into the melt pool of the melt container.
- the advantage is achieved that the filling and dosing process can be carried out quickly and efficiently and that the container containing the dosed melt can be easily transported and fed to other locations.
- the drawing shows a principle representation of the device according to the invention.
- the container 1 for the molten metal is provided with a container cover 2, while the valves 3 are provided for the negative pressure, excess pressure and ventilation.
- a pipe system 5 projects into the container 1 and can be connected to the common inlet and outlet 9 of the metering container 8.
- the dosing container 8 sits on a weighing system 6 and has inside a float 7 for measuring the level.
- a seal 10 is provided at the outlet of the inlet or outlet 9. With 11 a channel or an outlet is designated.
- the measuring devices are connected via a transmitter 12 to an input device 13 and a process computer 14, which in turn is connected to an output unit or a printer 15 and a terminal 16.
- a pressure line for the nitrogen and 17 a vacuum line to the vacuum pump are designated by 17.
- the bearing 19 serves for emptying the metering device 8, the channel 11 or the outlet being drawn under the outlet opening of the inlet or outlet 9.
- the common inlet and outlet is arranged such that it begins at the bottom of the metering container 8 and at least with its inlet and outlet opening lies above the level of the filling of the metering container 8.
- the function of the device for dosing and transporting molten metals has the following function.
- dosing container 8 When the dosing container 8 has reached its desired filling weight, which can be determined using a wide variety of measurement methods, and the pipe system 5 has been removed at the common inlet and outlet 9, dosing of the metal in FIG. 8 can be started.
- a new filling process or a new dosing process can be initiated.
- the dosing container 8 Since the dosing container 8 is not firmly connected to the pipe system 5, it can also be used as a transport container at the same time.
- the entire system can be easily connected to a process computer 14, as a result of which the various weights can be dosed in any order and the individual processes can be initiated.
- the entire system is operated with nitrogen via the feed line 17, with all points where there is a risk of oxidation being covered with nitrogen gas, which is supplied with a slight positive pressure above the critical points in relation to the prevailing air pressure.
