Description
Technical field
The invention belongs to magnesium metal smelting technical fields, and in particular to a kind of reduction refining integration smelting system,
Meet refining and the ingot casting that magnesium metal crude magnesium is realized under the premise of energy conservation and environmental protection requires.
Background technique
Pidgeon process (vacuum ferrosilicon process) refines magnesium crude magnesium obtained (Crystalline Magnesium) and contains many metal impurities and nonmetallic miscellaneous
Matter cause crude magnesium (Crystalline Magnesium) volume it is big, it is loose, be not easy keeping, storage, transport, and these metal impurities can with magnesium formed merchant's method
Electrochemical corrosion occurs for Buddhist nun's battery, and magnesium plays anode, and the metal impurities such as iron and nickel play cathodic process, accelerate the corrosion of magnesium.Cause
This crude magnesium, which must refine, can be only achieved the requirement that industry directly uses.
Vacuum breaker (air vacuum breaker) takes out crystallizer after production of magnesium by pidgeonprocess obtains Crystalline Magnesium, by Crystalline Magnesium from crystallizer
Refining plant is sent into abjection.Refining solvent is added in refining process first in crucible, Crystalline Magnesium is reloaded into, in 750 DEG C of temperature
Lower heating and melting is slowly added into Crystalline Magnesium and melting solvent, when the magnesium in crucible reaches the height of crucible dischargeable capacity, makes earthenware
Magnesium liquid temperature is maintained at 710 DEG C in crucible, refining solvent is then added, while being stirred (stirring while adding), mixing time is about
10 minutes, then temperature is risen to 740 DEG C (or 720 DEG C), and stand 5 ~ 10 minutes, protected after being cooled to 710 DEG C to magnesium liquid
Temperature completes the refining of crude magnesium.Magnesium burns in refining process, need to spread the burning that covering flux prevents magnesium, prevent the oxidation of magnesium
Loss.
Continuous casting machine ingot casting is used after refining, and the crucible for filling molten magnesium is hung in into the heat preservation of tipper valve and is two-mand ladle,
Tipper tilts, and in the ingot mould in crucible on magnesium liquid injection mould ingot conveyer, during ingot casting, spreads lower sulphur powder, makes sulphur powder
It burns on magnesium ingot surface and generates sulfur dioxide gas, prevent the oxidation of magnesium, casting process is completed.
Traditional refining furnace refining crude magnesium and casting process have some disadvantages:
1, traditional method of refining using air vacuum breaker and needs first to refine crude magnesium again from crystallizer taking-up, in reduction furnace
Oxygen, nitrogen combustion generate MgO, MgN in magnesium and air during vacuum breaker in crystallizer, reduce Mg yield, produce simultaneously
Raw dust polluting environment；2, the rate of recovery of smart magnesium is generally 94% or so (Zhu Danqing brief talks ferrosilicon process magnesium in conventional refining processes
Refinery practice and content of magnesium in design, light metal 1996(5) 42-48) refining slag are higher, and waste of resource pollutes environment；3, it refines
It needs to pick and place refining copple by driving in the process, operating process is dangerous；4, refining process is discontinuous, and a large amount of Mg are turning
Oxidation loss in fortune and fusion process；5, the refining solvent added in refining process is 2# solvent, can be produced in solvent adding procedure
Raw poisonous and harmful flue dust, and these flue dust cannot be handled effectively in collection, worker operation environment is poor, seriously polluted；6, casting process
Middle Mg is oxidizable, reduces ingot casting quality；Sulphur powder is spread during ingot casting and generates sulfur dioxide gas, pollutes environment；7, solvent essence
The magnesium ingot purity that refining casting obtains is only 99.95%, and quality is lower；8, the crystallizer of conventional shaft reduction tank is built in reductive jar
In cooling jacket, Crystalline Magnesium purity can be caused low with some impurity in magnesium vapor uphill process.
