Description
Technical field
The utility model belongs to magnesium alloy casting equipment technical field, and in particular to a kind of for matching somebody with somebody that casting ladle liquid level is protected
Gas holder.
Background technology
The chemical property of magnesium is active, is easily reacted with the oxygen in air, the magnesium alloy chemical property of liquid is more living
Sprinkle, a contact oxygen will be burnt, casting cycle punching, and casting ladle is swung up and down using casting ladle center line as axle at the kettle nozzle, in casting ladle
Liquid level is in mobile status all the time, if ullage does not have good gas shield, magnesium liquid will oxygen during rolling
Change burning, produce substantial amounts of magnesia slag inclusion, it is therefore desirable to configure fire-suppressant gas, fire-suppressant gas is passed into going out above casting ladle
There is the pinprick that drilling is bored in internal heat circle, in air ring, the magnesium liquid formed above casting ladle in a protective atmosphere, protection casting ladle.
The protective gas used at present mainly SF6And CO2Mixed gas, but be due to casting ladle position position and melting
Beside stove, it is separated by less than 1 meter, SF6Steel cylinder and CO2Steel cylinder can not be placed on casting ladle front, it is necessary to be put on the vacant lot of table side,
So it is accomplished by the air-flow of a pressure stability.Directly use SF6Steel cylinder and CO2Steel cylinder is flung into casting ladle, with gas in steel cylinder
Reduction, even if reaching maximum, pressure is also difficult to reach requirement, and protective gas is difficult to reach casting ladle liquid level.And pass through research table
It is bright, a certain amount of sulfur hexafluoride and carbon dioxide are mixed into atmosphere, is passed through for a long time, and the liquid level of magnesium alloy can just be risen
To good protecting effect, therefore distributing cabinet is set up, be pressurized using compressed air, it is to change that mixed gas, which is transferred in casting ladle,
The inevitable choice of prior art weak point.
The content of the invention
The purpose of this utility model is to solve prior art to there is magnesium alloy liquid level protecting effect difference and without supercharging distributing cabinet
Technical problem there is provided it is a kind of for casting ladle liquid level protect distributing cabinet, to overcome the deficiencies in the prior art.
To achieve these goals, a kind of distributing cabinet protected for casting ladle liquid level of the utility model, it includes cabinet；Its
Main points are that the blending tank I and blending tank II being interconnected by gas mixing pipe are provided with the cabinet；
The blending tank I respectively with SF6Air inlet pipe and CO2Air inlet pipe is interconnected；The SF6Air inlet pipe and CO2Air inlet pipe
On be respectively equipped with SF6Flowmeter and CO2Flowmeter；The SF6Air inlet pipe and CO2The air outlet of air inlet pipe is respectively protruding into mixing
The inside of tank I, and port is respectively equipped with equally distributed venthole；
The blending tank II is interconnected with compressed air inlet pipe and protective gas escape pipe respectively；The compressed air
Air inlet pipe is provided with pressure gauge I；The connectivity part of the protective gas escape pipe and blending tank II is provided with pressure gauge II；The protection
Gas escape pipe is provided with pressure-reducing valve.
It is the utility model reasonable in design, easy to use, due to blending tank I respectively with SF6Air inlet pipe and CO2Air inlet pipe
It is interconnected, gas is entered in blending tank II by gas mixing pipe again after being mixed in blending tank I；SF6Air inlet pipe and CO2Enter
The venthole being provided with the air outlet of tracheae can ensure the uniform of gas mixing；Blending tank II is connected with compressed air inlet pipe
Gas can be pressurizeed, and the final discharge at protective gas escape pipe, good protection can be played to magnesium alloy liquid level and is made
With.The utility model solves prior art magnesium alloy liquid level protecting effect difference and the technical problem without supercharging distributing cabinet.

Embodiment
Reference picture 1, the utility model it include cabinet 13；It is provided with and is mutually interconnected by gas mixing pipe 3 in the cabinet 13
Logical blending tank I 6 and blending tank II 7；
The blending tank I 6 respectively with SF6Air inlet pipe 1 and CO2Air inlet pipe 2 is interconnected；The SF6Air inlet pipe 1 and CO2Enter
SF is respectively equipped with tracheae 26Flowmeter 9 and CO2Flowmeter 10；The SF6Air inlet pipe 1 and CO2The air outlet of air inlet pipe 2 point
The inside of blending tank I 6 is not stretched into, and port is respectively equipped with equally distributed venthole 14, venthole 14 can play fully mixed
Close the effect of gas；
The blending tank II 7 is interconnected with compressed air inlet pipe 4 and protective gas escape pipe 5 respectively；The compression
Air intake duct 4 is provided with pressure gauge I 8；The connectivity part of the protective gas escape pipe 5 and blending tank II 7 is provided with pressure gauge II
11；The protective gas escape pipe 5 is provided with pressure-reducing valve 12.
Workflow：Sulfur hexafluoride gas is along SF6Air inlet pipe 1 is entered in blending tank I 6, adjusts SF6The gas of flowmeter 9
Body flow is 1L/min, and carbon dioxide is along CO2Air inlet pipe 2 is entered in blending tank I 6, adjusts CO2The gas stream of flowmeter 10
Measure as 1.5m3/h, two kinds of gases enter blending tank II 7 after the internal mix of blending tank I 6 is uniform along gas mixing pipe 3
In, compressed air is entered in blending tank II 7 along compressed air inlet pipe 4, and regulation admission pressure is 0.6 MPa, through secondary
After mixing, pressure-reducing valve 12 is opened, the reading of regulation pressure gauge II 11 is 0.03-0.06 MPas, and now, protective gas is just along guarantor
Shield gas escape pipe 5 is entered in the fire extinguishing air ring above casting ladle, the magnesium alloy liquid level in protection casting ladle.
After the present invention is implemented, the liquid level in casting ladle no longer catches fire, and improves security, and sulfur hexafluoride and titanium dioxide
The consumption of carbon is also decreased obviously, and reduces production cost.
