Description
Technical field
The utility model relates to a kind of metal smelting device, i.e. the continuous magnesium producing apparatus of electrothermal oven vacuum reducing.
Background technology
In prior art, MAGNESIUM METAL is a kind of light metal of silver color, is widely used in war industry field and part civilian industry field, its price comparison costliness.It mainly is shaft furnace or rotary kiln that magnesium is smelted production unit, collect magnesium at reduction jar-condenser intercrystalline, its shortcoming is the pelletizing that compacting is adopted in reduction jar smelting, produce for being interrupted, and the easy scaling loss of tank body, integral device cost height smelted, production efficiency is low, waste raw material and fuel contaminate environment, and cost value height.
The utility model content
The purpose of this utility model is to provide a kind of improved refining magnesium equipment at above-mentioned deficiency, has production efficiency height, the continuous magnesium producing apparatus of electrothermal oven vacuum reducing that cost is low.
Technical solution of the present utility model is: the continuous magnesium producing apparatus of electrothermal oven vacuum reducing it by the Sealed electric oven that connects in turn, vacuum-lines, condensing crystallizer or more than one placed in-line condensing crystallizer, vacuum unit etc. form.Described condensing crystallizer is preferably freezer condenser, and the magnesium vapor crystallization is fast, satisfies the rapid condensation of high temperature magnesium vapor, also can be water-cooled condenser.Condensing crystallizer is not limited to one, and the condensing crystallizer of a plurality of placed in-line differing tempss can be set, so that crystallization goes out other metallic element, improves the purity of magnesium, prevents or reduce the burning of magnesium; Condensing crystallizer is not limited to one, and a plurality of parallel connections can be set, and closes one, and can also working of other hocket, and realizes continuous production.
The utility model has the advantages that: 1, adopt electric furnace, equipment is simple, and less investment is easy to maintenance; Can directly smelt the magnesium material, and need not the processing of the group of pressure, simplified production technique, reduced labour intensity, improved production efficiency, reduced product cost, reduce or eliminate contaminate environment.2, freezing fast cooling is adopted in the magnesium vapor crystallization, the production efficiency height.3, plural serial stage, multi-channel parallel condensing crystallizer are set, are beneficial to crystallization sedimentation impurity, anti-magnesium burning, the purity and the quality product of raising magnesium.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Accompanying drawing is a structural representation sketch of the present utility model.
Embodiment
Referring to accompanying drawing, it is made up of the continuous magnesium producing apparatus of electrothermal oven vacuum reducing the Sealed electric oven 1, vacuum-lines 2, one-level condensing crystallizer 3, B-grade condensation crystallizer 4, the vacuum unit that connect in turn.
Electric furnace can be induction furnace, electric arc furnace, the hot stove in ore deposit or the like.In the furnace charge of directly packing into, stove temperature 1500-1600 ℃, autofeed and deslagging, continuous production.
Described condensing crystallizer 3,4 is a freezer condenser, this freezer condenser by refrigerator body 5 and the built-in crystallization of falling truncated cone shape tube 6 and tilting in tube 6 barrier plate 13 of bottom constitute.Freezer condenser makes its interior temperature lower, and the magnesium vapor crystallization is fast, satisfies the needs of the rapid condensation of high temperature magnesium vapor, also can adopt water-cooled condenser, and effect is not as the former.The crystallization of falling truncated cone shape tube 6 characteristics are upper coarse and lower fine, help pouring out after magnesium vapor crystallization and the crystallization.Barrier plate 7 can make magnesium vapor slow down, and is increased in the residence time in the crystallization of falling the truncated cone shape tube 6, is beneficial to the magnesium vapor crystallization.So the form of condensing crystallizer 3,4 with freezing be good, carry out freezing, water-cooled between can also be not at the same level and mix and be provided with.Condensing crystallizer 3,4 bottoms have covers 14, is convenient to put into or takes out the crystallization of falling truncated cone shape tube 6.
B-grade condensation crystallizer 4 in succession behind one-level condensing crystallizer 3, purpose is that the impurity of different Tcs is separated out, and improves the purity of magnesium.As in one-level condensing crystallizer 3, its temperature is controlled at 400 ℃-550 ℃, is beneficial to the magnesium vapor crystallization, and in B-grade condensation crystallizer 4, its temperature is controlled at 150 ℃-350 ℃, is beneficial to potassium, sodium vapor and other impurity crystallization.So other setting of crystallizer stage is to establish flexibly according to impurity situation in the ore, is not limited to this.So the form of above-mentioned condensing crystallizer 3,4 is freezing for good to be, can also between different stage, carry out freezing, water-cooled mixing setting.4 times outlets of B-grade condensation crystallizer connect the vacuum unit.
Vacuum-lines is divided into two branch roads, the corresponding condensing crystallizer that connects of each branch road.The right branch road of having stated among the figure connects condensing crystallizer 3,4, the condensing crystallizer 7,8 that also has left branch road to connect, condensing crystallizer 3, the 4 crystalline magnesium in so right branch road reach a certain amount of after, can close this branch road, open left branch road simultaneously and continue crystallization magnesium, realize continuous production.Above-mentioned branch road can also be more than two, is not limited thereto embodiment and lifts.Finally can realize multistage, multichannel, continuous production.
Have charge preheating pot 10 on the furnace lid 9, heat passes to foreheater 10 by bell 9, makes the furnace charge that enters in the stove have higher temperature, has promptly utilized waste heat, has saved fuel again, has improved production efficiency.Overheated for preventing foreheater 10, bell 9 can suitably add heat-resisting insulation material layer.Bell 9 and charge preheating pot 10 can be opened oscilaltion.
For reducing the furnace charge cooling of preheating, batch can 12 is given in the insulation that has sealing on the electric furnace load hopper 11, and essence is covered an insulation casing exactly, makes the furnace charge of packing into reduce calorific loss.
In actual the use, it still is a plurality of one to reinstate that the single use of batch can 12, condensing crystallizer is given in the charge preheating pot 10 that has on the bell 9, the insulation on the electric furnace load hopper 11, selects for use flexibly according to reality fully.
The furnace charge of using in the electric furnace, promptly can be ore and reductive agent by the mixed furnace charge of formulation ratio, also can be the pelletizing that furnace charge is pressed into behind grinding, in this way before a kind of furnace charge, but continuous production then, otherwise be that the pelletizing furnace charge then can semicontinuously be produced.
Production process: conveying magnesium vapor → condensation-crystallization → treat vacuum refinement is smelted → is vacuumized in ore and auxiliary material proportioning blended furnace charge (or grinding pressure ball group) → sealing.
