Description
Technical field
The present invention relates to melt carbothermy refining magnesium technical field more particularly to a kind of melt carbothermy magnesium smelting devices.
Background technique
Magnesium is reserves metallic element extremely abundant in the earth, accounts for about the 2.1%--2.7% of earth gross mass, China's storage
Amount is the global maximum country of magnesium resource reserves.Currently, having verified tens billion of tons.Magnesium and magnesium alloy have specific gravity small, and intensity is high,
Damping property is good, shock resistance, and machinability is good, and thermal conductivity is good, can be recycled and recycles, and environmental pollution is few, excellent with excellent environment
Gesture and performance advantage, it is applied widely, it is a kind of recyclable rare metal.Magnesium industry is greatly developed in China and complete
Ball has apparent resources advantage and the market advantage.
Magnesium refining method in the world mainly has electrolysis method and thermal reduction two major classes.Thermal reduction is to be with dolime
Raw material, using Al, C or silicon as reducing agent, using iron as thermal conducting agent, magnesium metal is made in reduction-oxidation magnesium under elevated temperature in vacuo.From
So far, mostly magnesium worker processed is all around how to improve and improve reduction for Canadian skin river teaching inventive " Pidgeon process "
Phase improves the technical problems such as magnesium rate and is studied.CN104120282B Northeastern University Zhang Tingan et al. was invented in 2014
A kind of " the quickly method of continuous refining magnesium ", the technical solution adopted is that: ingredient pelletizing, pelletizing calcining, by calcined high temperature ball
Group, without cooling be continuously fed in closed high temperature reduction furnace under protection of argon gas, then in the argon atmosphere of flowing into
The reaction of row high temperature reduction, reaction temperature are 1300-1600 DEG C, are continuously available high temperature magnesium vapor, and mix with argon gas, shape
High temperature reduction furnace is continuously excluded at high-temperature gas mixture, while reducing slag, high temperature magnesium vapor obtains magnesium metal through condensation.The method
Reaction speed is fast, and the recovery time, the rate of recovery of magnesium was increased to 88% in 90min.CN103882246B discloses a kind of vacuum
Magnesium smelting device and its method, melt using by ferrosilicon, and method of magnesium oxide is blown into ferrosilicon melt, restore magnesium processed.Above-mentioned two
Kind method after having the drawback that (1) reaction a period of time, is needed Si-Fe-SiO2 melt, after through a long time is cooling, from
It is taken out in reduction furnace, recharges raw material；(2) above two method is all made of silicon and makees reducing agent, and iron is thermal conducting agent, and silicon and iron exist
During reaction, silicon is gradually oxidized generation solid silica, silica melting point at 1650 DEG C or so, silica
Boiling point is at 2230 DEG C, and under the reaction conditions, silica is mixed with iron, and with the continuous progress of reaction, silicon is gradually decreased, and two
The output of silica is continuously increased, and iron liquid thermal conductivity gradually decreases, and when parts by weight of the silicon in iron liquid are less than 30%, is needed
Stop experiment, by the iron liquid and reducing slag all removings in reduction furnace, thereby results in the waste of thermal conducting agent iron, production cost is still
It is higher, and whole preparation process can only be referred to as " quick semicontinuous refining magnesium ".To sum up, silicon is reducing agent, iron is thermal conducting agent, reduction
Magnesia prepares magnesium metal, and since its reducing agent is solid, thermal conducting agent is liquid-solid phase, product is solid, thermal conducting agent itself is not joined
With react, can not but be separated with raw material and product, reaction process is caused to need continuously to supply thermal conducting agent, so, no matter
How the reaction carries out technological improvement, and the continuous no consumption that all cannot achieve thermal conducting agent uses, and production cost is still higher, and is
Slag dumping can only realize semi-continuous production.
The reducing agent price of silicothermic process is higher, and thermal conducting agent can not reuse, and reduction with carbon obtains the side of magnesium metal
Method is that people pay attention to always.In the 1830's, the research about carbon thermal reduction magnesium is constantly being carried out always, but
Being mostly is the research carried out with the reaction mechanism for studying carbon thermal reduction magnesia magnesium, and is essentially all to carry out in laboratory
, the not no relevant report about carbon thermal reduction magnesia magnesium industry so far.
Therefore, a kind of melt carbothermy magnesium smelting device how is provided, to reduce cost, reduce energy consumption, raising production efficiency
High and realization continuous production, is current those skilled in the art technical problem urgently to be resolved.
