Definitions
- the present invention relates to a method for operating furnace systems for magnesium alloys, in which a bathroom surface is covered with a protective gas which contains a sulfur compound.
- SF 6 is used as such a protective gas, which reacts with the magnesium of the melt and forms a protective layer which protects the melt from the ingress of atmospheric oxygen. Mixtures of SF r and nitrogen are sometimes used for this purpose. Since SF 6 is a greenhouse gas, its use is environmentally unsafe. In addition, the cost of this gas is relatively high.
- S0 2 As protective gas.
- S0 2 is available relatively inexpensively and, like SF (), forms a protective layer on a magnesium melt.
- S0 2 has hitherto been prevented by the fact that it is an extremely unpleasant smelling gas which is harmful to health and corrosive to corrosion in medium to high concentrations.
- S0 2 in a conventional manner, an escape of gas from the furnaces or the like cannot be avoided, which leads to an impermissible pollution of the environment. In particular, the MAK values are exceeded by far.
- the object of the present invention is to provide a method which, on the one hand, enables safe treatment of magnesium melts, but on the other hand causes the least possible environmental pollution.
- this object is achieved in that a mixture of SO 2 and an inert gas is used as the protective gas, the volume fraction of SO 2 being set precisely to a value which is preferably in a range between 0.3% and 1.5% between 0.5% and 1.0%.
- the volume fraction of SO 2 being set precisely to a value which is preferably in a range between 0.3% and 1.5% between 0.5% and 1.0%.
- Nitrogen is particularly preferably used as the inert gas. Nitrogen is available at low cost and is not environmentally critical. In a particularly advantageous embodiment of the method according to the invention it is provided that the mixing of SO 2 and the inert gas takes place in an air-conditioned room, the temperature of which is kept above 22 ° C. and preferably in a range between 25 ° C. and 35 ° C. It has been found that a satisfactory mixture of S0 2 and nitrogen is only possible at a certain minimum temperature at a power pressure> 2 bar. In addition, the mixture in an air-conditioned room can reliably avoid temperature-related volume and pressure fluctuations in the gases involved. A temperature of about 30 ° C. is particularly preferred.
- the present invention relates to a device for producing a protective gas for furnace plants for Magncsiumlcgicrungen with a pre-container for a sulfur compound, a storage container for an inert gas and a mixing device.
- the device according to the invention is characterized in that the mixing device is designed for precise flow control of SO and nitrogen, and is arranged in an air-conditioned room.
- Safety gas cylinders are installed in an air-conditioned room to hold SO 2 bottles. Nitrogen is taken from a normal tank.
- the mixing of S0 2 and nitrogen takes place via electronic mass flow meters, which are arranged in the air-conditioned room.
- the gas mixture produced in this way is transported to the corresponding furnace systems via pipes and adapted to consumption via local control systems. These can be melting furnaces. Trade warm shark ovens, dosing ovens and ingot casting belts for magnesium solutions.
- S0 2 sensors are installed in the safety gas cylinders, which already respond to low S0 2 concentrations. After an S0 2 bottle has been emptied, it is flushed with the corresponding pipelines with nitrogen in order to rule out a health hazard during bottle washing. In this way it can be reliably prevented that SO 2 gets into the environment.
- FIG. 1 The basic circuit diagram of a device according to the invention is shown in FIG.
- the broken lines 1 describe the components which are arranged in two security cabinets.
- Gas bottles 2 serve as storage containers for sulfur dioxide, which are supplied to a manifold 4 via shut-off valves 3.
- a control line 5a, which controls a solenoid valve 6, is supplied via a manometer 5.
- a supply line 8 for S0 2 is connected via a further shut-off valve 7.
- a storage container 9 for nitrogen is connected via a line 10, a shut-off valve 11 and a check valve 12 to the distribution line 4 in each of the two safety cupboards 1 in order to provide nitrogen for flushing the lines when the bottles 2 are changed.
- a manometer 13 indicates the nitrogen pressure in a main nitrogen line 16.
- the individual bottles 2 are connected to an exhaust gas collection line 19 via shut-off valves 17 and exhaust gas lines 18.
- the distribution line 4 is vented into the exhaust manifold 19 via its own shut-off valves 20.
- the mixing device for supplying the individual consumers is shown in the right section of the figure. Since the individual mixers 21 are basically constructed in the same way, only one is designated with a reference number and is explained in the description.
- the individual mixers 21 are supplied with nitrogen via a first vertical bar 22 and with sulfur dioxide via a second vertical bar 23.
- a third vertical bar 24 is used to connect the mixers 21 to the exhaust manifold line 19.
- Shut-off valves 25 and 26 are provided in the individual mixers 21, which are connected to the vertical bar 22 and 23, respectively.
- Pressure gauges 27 and 28 indicate the nitrogen and sulfur dioxide pressure after the shut-off valves 25 and 26, respectively.
- a shutoff valve 29 for purging is provided between the nitrogen line and the sulfur dioxide line, which is followed by a check valve 30.
- Highly precise mass flow rate measurements 31 for nitrogen and 32 for sulfur dioxide serve to set a precise ratio of the two gases.
- Filters 33 and 34 are connected upstream of the flow measurements 31 and 32.
- shut-off valves 35 and 36 and a check valve 37 in the nitrogen line the gases are brought together into a supply line 38, which is provided with a pressure gauge 39 and a shut-off valve 40.
- a flushing line 41 with a shut-off valve 42 serves to avoid environmental pollution during maintenance work or the like.
- the entire arrangement, which is shown in the figure, is arranged according to the invention in an air-conditioned room, which is kept at a temperature of about 30 ° C. In this way, the mixing ratio of the gases can be kept at a precisely predetermined value and good mixing can be ensured.
- Mcngcnrcgler not shown, can be provided for the individual consumers, but these only influence the quantity of the gas mixture supplied and not the composition of the gas.
- the present invention thus not only enables cost savings, but also a significant reduction in environmental pollution and particularly safe operation when handling magnesium melts.
