Process are as follows: be uniformly mixed the metal oxide (CaO, MgO, SrO, BaO) obtained by calcining with reducing agent powder appropriate,
Balling-up is suppressed, heating reduction under vacuum conditions is then charged into reductive jar and obtains corresponding metal.Above-mentioned metal smelt process
Difference other than raw material is different, reducing agent used also difference: (the most commonly used is the silicon containing expensive 75% with ferrosilicon for magnesium metal
Ferroalloy), and in addition the smelting of metal then makees reducing agent with metallic aluminium powder；Temperature required for different metal heat-treats also slightly has
Difference.But device used is essentially identical, commonly mainly horizontal tank, in horizontal tank in the heat resisting steel in heating furnace high-temperature area
Pelletizing feed is reduced under vacuum and enters condensation segment at gaseous state, in the outer diameter and the comparable iron of condenser that condensation segment inner wall is placed
Matter cylinder inner surface deposits.
Above-mentioned reaction unit there are the problem of to be mainly reflected in metal purity bottom, impurity content that reduction obtains high.Especially
It is that the metal restored when alkali metal content is high in raw material frequently results in kindling when coming out of the stove.In order to put out a fire,
It can only be spread and be spilt with sand, further increase impurity content.Moreover, the reduction process of above-mentioned metal mostly uses hand stock,
The dusting of part pelletizing is inevitably caused during charging, during vacuumizing part powder with metallic vapour sweep along into
Enter in metallic crystal.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of improved metal magnesium, the cooling section of calcium smelting reductive jar.
The cooling section includes crystallizer, vacuum tube and gasket, and cooling section diameter dimension is the 1.0 of reductive jar diameter dimension
~3.0 times, the increase main purpose of crystallized region caliber size is to reduce the flowing velocity of gas phase, increases high vapour pressure impurity
Separating effect, while reducing the speed of dust is conducive to the sedimentation of dust, reduces solid particle being mingled in a metal；Knot
Brilliant device is located in the middle part of cooling section, cooling section tube wall opening connection vacuum tube, and cooling section tube wall is at end panel and crystallizer
It is inside passed through cooling water, gasket is set between cover board and cooling section, crystallizer is radial plate armature, improves metal production
The crystalline state of object, it is particularly possible to which metallic vapour-crystal plane temperature is adjusted by the adjusting of cooling medium in condition crystallizer
Degree, so as to adjust gas phase degree of supersaturation, obtain required for metallic product appearance；Crystallizer back gauge cooling section outer wall is
10-15mm, the gap reserved between crystallizer and tube wall can guarantee low melting point, the potassium sodium impurity of high vapour pressure is carried on the back in crystallizer
Portion's lower temperature goes out to deposit and improve the purity of metal.
Preferably, cooling section diameter dimension is 1.5 times of reductive jar diameter dimension.
Crystallizer is arranged on the face perpendicular with the metallic vapour direction of motion.
Crystallizer is provided opposite to metallic sieve.
Metallic sieve aperture is 80~200 mesh, and the metallic sieve number of plies is 2~10 layers.
The advantageous effects of the above technical solutions of the present invention are as follows:
In above scheme, is conducive to the sedimentation of dust, reduces solid particle being mingled in a metal；Improve metallic product
Crystalline state, it is particularly possible to metallic vapour-crystal plane temperature is adjusted by the adjusting of cooling medium in condition crystallizer,
So as to adjust gas phase degree of supersaturation, obtain required for metallic product appearance, improve the purity of metal.
