Abstract
The utility model belongs to an item of technical problem in the field of metallurgy and casting. The problem which is mainly solved is making aluminum purification by a program-controlled crystallizer with microprocessor. The crystallizer is suited for the situation of Chinese aluminum resources. The freezing speed of the crystallizer can be controlled at 5 to 10 mm / mln range by microcomputer, which can solve the technical problem that the crystallizer of Japanese patent is unsuitable for Chinese aluminum purification. If the utility model is in production of aluminum purification, the cost of electric can be saved more than 50 percent than that with three-layer electrolysis method and the cost of per ton refined aluminum can be reduced 30 percent or so.
Description
The technology of the present invention relates to metallurgy, casting field.
In prior art,, at present, have only Japan to reach the level of production application about the aluminium of purifying with directional solidification method.The immediate prior art of this respect is Patent No:J Δ J8216567-KoKai; Japan.This patent is than three layers of traditional electrolytic process technology advanced person, and its device mainly contains body of heater, and crystallizer removes the dirty liquid bag, electromagnetic induction coil.This patent is than traditional refined aluminium production power saving 20%, and still, its device is not suitable for purifying, and to contain the si amount many, contain the few aluminium of Fe amount, and the bauxite resource of China just like this.In addition, the handiness of row's dirty liquid bag is also not enough.
Design of the present invention is: heat tracing aluminium liquid under microcomputer control, magnetic field stir and directional freeze is purified refined aluminium.This method is than three layers of electrolytic process power saving more than 50%.This device high si that is suitable for purifying, the aluminium of low Fe, with this device may command setting rate in the 5-10mm/min scope.Method of purification is: the flow at casting mold top control aluminium liquid, and inject in the casting mold continuously, and stirred with high-intensity magnetic field, use micro-processor controlled haulage gear one of casting mold bottom design, make aluminium liquid continuously with the speed directional freeze of 5-10mm/min.When solidifying the initial stage, haulage gear drawing initial solidification seat (27), stable solidification stage strand thereafter constantly is cut to be transported, remaining strand is conducted oneself with dignity and by micro-processor controlled running roller haulage gear drawing, simultaneously, because function composite by electromagnetic stirring constantly exchanges the dirty liquid of solidified front and the fresh aluminium liquid on top, when the impurity in the aluminium liquid reaches finite concentration, get rid of dirty liquid with vacuum type row dirty liquid bag.The aluminium of so just having purified.
Accompanying drawing is the device of directional solidification method purification aluminium.It is that body of heater, crystallizer, moving magnetic field producer and row's dirty liquid bag are formed by four major parts.Wherein, body of heater is made up of muff (1), heating unit (2), boiler tube (3), insulation filler (5) and casting mold (4); Crystallizer is a ring-type water jacket (9); The moving magnetic field producer is made up of electromagnetic induction coil (8) and insulated water jacket (7); Vacuum type row dirty liquid bag is made up of a sets of transmission mechanism of inclusion (25) and drive inclusion (25) motion.
Relative configuration relation and the insulated water jacket (7) who is characterised in that crystallizer ring-type water jacket (9) and electromagnetic induction coil (8) of the present utility model for realizing that this configuration relation designs, make the bottom of electromagnetic induction coil (8) and crystallizer ring-type water jacket (9) just in time be positioned at the top of the solidified front that shell thickness is 8-12mm (28), and insulated water jacket (7) must place the top of crystallizer ring-type water jacket (9), be between insulation filler (5) and the electromagnetic induction coil (8), the top of its insulated water jacket's (7) top and electromagnetic induction coil (8) remains on the same level attitude.And existing device damages because of the electromagnetic induction coil (8) that can't overcome the moving magnetic field producer is heated, and therefore, is configured in below secondary cooling system (26) zone of crystallizer ring-type water jacket (9).Like this, stirring action only can be played by the residual Al liquid to ot-yet-hardened to by crystallizer the time in magnetic field, simultaneously,, magnetic field just can reach in the aluminium liquid (6) because will seeing through thicker solidified shell, so, just reduce magneticstrength greatly, thereby lower stirring efficiency.The utility model is owing to changed crystallizer ring-type water jacket (9), electromagnetic induction coil (8) and insulated water jacket's (7) configuration relation, make electromagnetic induction coil (8) be in the top that aluminium liquid (6) shell thickness is the solidified front (28) of 8～12mm, reduced the influence of shielding effect of the solidified shell of aluminium liquid (6), thereby can play aluminium liquid (6) is carried out comprehensively stirring action intensely, improve purification efficiency greatly, more can demonstrate its advantage to containing the si height and containing the low aluminium liquid of Fe especially.
Be specific embodiments of the invention below.At first, be heated to 800 ℃ of insulations with the aluminium ingot of fusing (use resistance furnace, sweet boiler all can).The about 2mm degree of depth of inner ring that then initial solidification seat (27) is pushed crystallizer ring-type water jacket (9) makes it close contact.Open insulated water jacket's import (12) and outlet (13), open the water-in (14) and the water outlet (15) of crystallizer ring-type water jacket (9) simultaneously, make the water coolant among crystallizer ring-type water jacket (9) and the insulated water jacket (7) unimpeded.Again heating unit (2) is switched on, make its temperature reach 800 ℃ to give hot-cast type (4), at last aluminium liquid (6) is injected casting mold (4) continuously, start the power supply of electromagnetic induction coil (8) simultaneously, control voltage is 40V, and aluminium liquid (6) is stirred.Along with solidifying of aluminium liquid (6), the traction roller-way of initial solidification seat (27) bottom wherein is advisable with the speed of 6mm/min with 5-10mm/min speed drawing initial solidification seat (27) under microcomputer control.After strand (10) that purification finishes reaches certain-length, transported by special cutting machine cutting.Remaining strand (10) is just no longer used initial solidification seat (27), and directly is pulled roller-way clamping drawing.When impurity reaches finite concentration in the aluminium liquid, by pulley (16), electric motor and rolling wheel (17), trundle (18), wireline (23), slide bar (22), the transmission rig of slide block (21), the vacuum type row chamber fluid inclusion (25) that is under the certain temperature, send in the casting mold (4), unlatching taps into vent valve (19), make in the lift cylinder (24) and move on the piston, at this moment, aluminium liquid then is sucked in row's dirty liquid inclusion (25) automatically, then, close purging valve (20), to tap into vent valve (19) commutation again, the middle piston of lift cylinder (24) is moved down, stop up dirty liquid inclusion (25) bottom outlet, will arrange dirty liquid inclusion (25) lifting by above-mentioned transmission rig again and transport.Continue to inject aluminium liquid (6), repeat above-mentioned purification process.
Computer controlled process is as follows:
The present invention need not be traditional three layers of electrolytic process purification refined aluminium, making purity is that 99% general aluminium is mentioned more than 99.94%.More than 50%, can make technology purification refined aluminium per ton cost descend about 30% than three layers of electrolytic process power saving.
