The few vaccum sensitive stove refining magnesium system of dye and its magnesium refining method.
Background technology
Magnesium is the extremely abundant metallic element of reserves in the earth, accounts for the 2.1%---2.7% of earth gross mass, China's storage
Amount is the maximum country of global magnesium resource reserves.At present, tens billion of tons have been verified.Magnesium and magnesium alloy have proportion little, and intensity is high,
Damping property is good, shock resistance, and machinability is good, and heat conductivity is good, and recyclable regeneration, environmental pollution are few, with excellent environment
Advantage and performance advantage, use range extensively, are a kind of rare metals of reusable edible.Magnesium industry is greatly developed in China and
The whole world has obvious resources advantage and the market advantage.
The production method of magnesium mainly has two class of magnesium chloride fused salt electrolysis process and thermal reduction at present.At present, global magnesium yield
85% produced by the metal deoxidization in thermal reduction, i.e. " Pidgeon process ".Thermal reduction is produced with metal deoxidization
In " Pidgeon process " as a example by, there is many deficiencies at present production.1. heat conduction radius is big, and heat loss is big, and environmental pollution is serious, reduction
Time length 12-14 hours；2. all artificial to operate, field worker high labor intensive, efficiency are low；3. production cost is high, mainly deposits
In high energy consumption, reductive jar high cost, recovery rate are low, and economic benefit is undesirable；4. scale can not be formed continuously to produce, is not met
The requirement of modern industry development.
Some countries utilize own resource condition, using producing chlorine in magnesium chloride fused salt electrolysis process production process, right
Personnel and environmental pollution and pollution, current this production method are rarely employed.
At present, China's magnesium metal production has accounted for the 85% of global share, and big portion is produced using thermal reduction, i.e., " Pidgeon process "
Production.
" Pidgeon process " production technology of currently available technology be mainly with dolime as raw material, ferrosilicon as reducing agent,
Fluorite is catalyst, carries out batching.Balling-up, referred to as pelletizing are suppressed after grinding.Pelletizing is loaded in reductive jar, is heated to
1200 DEG C, inside is evacuated to 13.3Pa or higher, then produce magnesium vapor.Magnesium vapor is formed in the condenser of reductive jar front end
Crystalline Magnesium, also known as crude magnesium.Jing flux-refinings again, output commodity magnesium ingot, i.e., smart magnesium.Production of magnesium by pidgeonprocess production process production of magnesium by pidgeonprocess
Production process (1) dolomite calcination：Dolomite is heated to into 1100～1200 DEG C in rotary kiln or shaft furnace, burn till forge it is white
(MgO·CaO).(2) dispensing ball：White, ferrosilicon powder and Fluorspar Powder batching, grinding will be forged, ball will be then pressed into.(3) also
It is former：Pellet is heated to into 1200+10 DEG C in reductive jar, under 13.3Pa or more high vacuum condition, is kept for 8～10 hours, oxygen
Change magnesium-reduced into magnesium vapor, after condensation, become crude magnesium.(4) refine ingot casting：Crude magnesium heating is melted, under about 710 DEG C of high temperature, is used
After solvent refined, magnesium ingot is cast, also known as smart magnesium.(5) pickling：Magnesium ingot is cleaned into surface with sulphuric acid or nitric acid, surface is removed and is mingled with,
Make surface aesthetic.(6) gas making workshop：Raw coal is converted into into coal gas, is used as fuel.Directly do not made using the magnesium factory of raw coal
Gas workshop.
In currently available technology, Chinese Patent Application No. is 95100495.6, entitled electric furnace molten charge silicothermic reduction vacuum refining
Magnesium new technology, inherits " Pidgeon process " magnesium with ferrosilicon as reducing agent, in hot state, can restore magnesium this " Pidgeon process "
Core theory.By reduction reaction, i.e., magnesium steam is produced under the conditions of heating, magnesium liquid is changed into by condenser then, but specially
The sharp phase fails, no Production Example note, and is unable to continuous prodution.Chinese patent (201010255111.9), single unrestrained stain pipe silicon
Bath vacuum circular flow magnesium-smelting device and its method, the double unrestrained stain pipe silicon bath vacuum circular flow magnesium-smelting dresses of Chinese patent (201010255097.2)
Put and its method, and a kind of method and its equipment of vacuum circular flow melt magnesium-smelting silicothermic process of patent (201080000976.9).Pin
And production defect backward in technique to refining magnesium at present, it is proposed that the viewpoint of melt ferrosilicon process reduction refining magnesium, but due to single, double dip pipe
The restriction of circulation mechanism it is high to silicon heating bath volume requirement, heating difficulty is larger, slags tap and causes to be unable to continuous prodution, to existing
Field requires harshness, and investment is very big with production scale, and in the environment of exposure air, magnesium metal recovery rate is low.
