Description
Technical field
The present invention relates to metal smelt system and method, be specifically related to a kind of productivity height, expense is low,
Make melt carbothermy induction furnace vacuum refining magnesium system low in the pollution of the environment and magnesium refining method thereof.
Background technology
Magnesium is the metallic element that in the earth, reserves extremely enrich, and accounts for the 2.1%---2.7% of earth gross mass,
China's reserves are the countries that whole world magnesium resource reserves are maximum.At present, tens billion of ton has been verified.Magnesium and magnesium alloy
Having proportion little, intensity is high, and damping property is good, shock resistance, and machinability is good, and heat conductivity is good, recyclable regeneration
Utilizing, environmental pollution is few, has excellent environmental advantage and performance advantage, and range is extensive, is one
Plant the rare metal of reusable edible.Greatly develop magnesium industry, in China and the whole world, there is obvious resources advantage
And the market advantage.
The production method of magnesium currently mainly has magnesium chloride fused salt electrolysis process and thermal reduction two class.At present, the whole world
The 85% of magnesium yield is all to be produced by the metal deoxidization in thermal reduction, i.e. " Pidgeon process ".Thermal reduction
As a example by method produces " Pidgeon process " in metal deoxidization, produce at present and there is many deficiencies.1. heat conduction half
Footpath is big, and heat loss is big, and environmental pollution is serious, recovery time length 12 14 hours；2. all manual operations,
Field worker labor intensity is big, and efficiency is low；3. production cost is high, is primarily present energy consumption high, reductive jar cost
Height, recovery rate is low, and economic benefit is undesirable；4. can not form scale to produce continuously, not meet modern big
The requirement of industrial development.
Some country utilizes own resource condition, uses in magnesium chloride fused salt electrolysis process production process and can produce chlorine
Gas, to personnel and environmental pollution and pollution, current this production method is rarely employed.
At present, China's magnesium metal produces and has accounted for the 85% of whole world share, and big portion uses thermal reduction to produce, i.e.
" Pidgeon process " produces.
" Pidgeon process " production technology of currently available technology is mainly with dolime as raw material, ferrosilicon is
Reducing agent, fluorite are catalyst, carry out batching.Balling-up, referred to as pelletizing is suppressed after grinding.By pelletizing
Loading in reductive jar, be heated to 1200 DEG C, inside is evacuated to 13.3Pa or higher, then produce magnesium vapor.
Magnesium vapor forms Crystalline Magnesium, also known as crude magnesium in the condenser of reductive jar front end.Again through flux-refining, output
Commodity magnesium ingot, i.e. essence magnesium.Production of magnesium by pidgeonprocess production process production of magnesium by pidgeonprocess production process (1) dolomite is forged
Burn: dolomite is heated to 1100～1200 DEG C in rotary kiln or shaft furnace, burns till and forge white (MgO CaO).
(2) dispensing ball: white, ferrosilicon powder and Fluorspar Powder batching, grinding will be forged, be then pressed into ball.
(3) reduction: pellet is heated to 1200+10 DEG C in reductive jar, at 13.3Pa or more high vacuum condition
Under, keeping 8～10 hours, magnesium oxide is reduced into magnesium vapor, becomes crude magnesium after condensation.(4) refine casting
Ingot: crude magnesium is added heat fusing, under about 710 DEG C of high temperature, after solvent refined, casts magnesium ingot, also known as essence
Magnesium.(5) pickling: magnesium ingot sulphuric acid or nitric acid are cleaned surface, removes surface and is mingled with, make surface aesthetic.
(6) gas making workshop: raw coal is converted into coal gas, uses as fuel.The magnesium factory of raw coal is directly used not have
There is gas making 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, and can be also
Former go out magnesium this " Pidgeon process " core theory.By reduction reaction, under the conditions of heating, i.e. produce magnesium steam
Vapour, then becomes magnesium liquid by condenser, but patent life lost efficacy, does not produce example note, and can not connect
Continuous metaplasia is produced.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 device of Chinese patent (201010255097.2) and side thereof
Method, and the method for patent (201080000976.9) a kind of vacuum circular flow melt magnesium-smelting silicothermic process and equipment thereof.
For refining magnesium is backward in technique at present and produces defect, it is proposed that the viewpoint of melt ferrosilicon process reduction refining magnesium, but by
Circulation mechanism in single, double dip pipe restricts high to silicon heating bath volume requirement, and heating difficulty is relatively big, slags tap
Cause can not continuous prodution, harsh to field requirement, investment and production scale are very big, and big exposing
In the environment of gas, magnesium metal recovery rate is low.
