Description
Technical field
The utility model relates to a kind of online degassing and filtration mechanism, belongs to the online aluminium melt purifying treatment facility field of rolling round aluminum rod production line.
Background technology
Electrical aluminum rod is the work in-process of making cable, electric wire, and is along with the high speed development of domestic and external power industry, also more and more higher to the performance requriements of electrical aluminum rod.The tissue of controlling the aluminium bar in process of production changes the task of top priority of each enterprise when producing high-quality electrical aluminum rod.Electrical aluminum rod mainly is to produce on the continuous casting and rolling production line, production process mainly is aluminium liquid ingredient composition, the purification of aluminium liquid, ingot casting and rolling, wherein aluminium liquid purifies particularly important, because in electrolysis and melting process and go out aluminium, fall in the processes such as stove, metaideophone, inevitably make and sneak into a certain amount of hydrogen and other inclusiones (as aluminum oxide) in the aluminium liquid, the existence of hydrogen and inclusion not only has influence on the purity of aluminium, main is the inside generation pore and the slag inclusion of strand, and these defectives of strand are very big to electric conductivity, intensity and the plasticity influence of electrical aluminum rod.Must remove slag inclusions such as hydrogen and aluminum oxide, in the hope of obtaining more purified aluminium liquid.The present domestic special online rotation getter that has, except large-lot producer of a few family is applied to this technology on the electrical aluminum rod continuous casting and rolling production line, remaining enterprise uses hardly, though the most of enterprises of the ceramic plate filtering technique of tundish use, but mostly being easy device uses on production line, ceramic filter plate is changed frequent, and filter effect is also bad.
Summary of the invention
The purpose of this utility model be for overcome that above-mentioned the deficiencies in the prior art provide that a kind of ceramic plate filtering technique with online rotation getter and tundish organically combines can be before the molten aluminium casting the online degassing and filtration mechanism of purification of realization molten aluminium.
The purpose of this utility model is realized by following mode:
The utility model comprises tundish, ceramic filter plate, the tundish gland, the rotation getter, the controlling box of rotation getter, graphite rotator, it is characterized in that: tundish is the abnormal shape bag that an inside is provided with step, by casting lining, three layers of formation of refractory materials insulating interlayer and shell, in tundish, be provided with a refractory materials partition wall, middle package space is divided into two cavitys in partition wall bottom UNICOM, two tundish glands cover respectively on two cavitys in tundish top, be provided with the entrance and exit of tundish on the top of tundish both sides, ceramic filter plate be located at tundish by the outlet one side cavity in the outlet of tundish is all blocked; Be provided with the watertight chest of bringing the gas interface into outside the housing of rotation getter, establish gas meter on the watertight chest, the inlet mouth of gas meter is located in the watertight chest, and the air outlet is connected with the rotation getter; Graphite rotator is connected with the rotation getter, tundish by the gland on the inlet side cavity on have the opening that passes in and out for graphite rotator.
The utility model has the advantages that: routine maintenance is simple and easy, durable in use, before the molten aluminium casting, realized the purification of molten aluminium, make the hydrogen content of 100g molten aluminium reach 0.1ml (1 grade of pinhole rate grade), the dehydrogenation rate is about 50%, the filter cleaner effect is obvious, and the few and molten aluminium composition of alloying element scaling loss evenly reaches temperature-stable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to accompanying drawing, the utility model comprises tundish 9, ceramic filter plate 1, tundish gland 2 and 7, rotation getter 4, the controlling box 3 of rotation getter, graphite rotator 8, tundish 9 is abnormal shape bags that an inside is provided with step, by casting lining 10, refractory materials insulating interlayer 11 and shell constitute for three layer 12, in tundish, be provided with a refractory materials partition wall 14, middle package space is divided into two cavitys in partition wall bottom UNICOM, tundish gland 2 and 7 covers respectively on two cavitys in tundish top, to outlet, ceramic filter plate 1 is located in the cavity of outlet one side the B of tundish all being blocked to exporting by B of tundish 9 to the A that is provided with tundish on the top of tundish 9 both sides to inlet and B; Be provided with the watertight chest 6 of bringing the gas interface into outside the housing of rotation getter 4, establish gas meter 5 on the watertight chest 6, the inlet mouth of gas meter 5 is located in the watertight chest 6, and the air outlet is connected with rotation getter 4; Graphite rotator 8 is connected with rotation getter 4, has the opening for graphite rotator 8 turnover on tundish gland 7.
During application, rotation getter 4 is placed and makes graphite rotator 8 vertically enter tundish 9 by the opening on the tundish gland 7 on the tundish gland 7, nitrogen or argon gas gas cylinder 13 are connected with the intake interface of watertight chest 6, molten aluminium enters special-shaped casting lining 10 by the A of tundish 9 to inlet, make nitrogen or argon gas enter watertight chest 6 by the valve of regulating gas cylinder 13, re-adjustment under meter 5, nitrogen or argon gas are blown in the molten aluminium by the gas blow pipe on the rotation getter, by the graphite rotator 8 of controlling box 3 controls revolution getters 4 with fixed speed driven rotary, the gas breaking that is blown in the molten aluminium is become a large amount of disperse bubbles, and it is dispersed in the molten metal.Bubble by partial pressure difference and surface adsorption principle, absorbs the hydrogen in the molten aluminium in melt, the adsorption and oxidation slag inclusion, and rise and taken out of bath surface with bubble, molten aluminium is purified.The molten aluminium that purifies arrived before the ceramic filter plate 1 through undercurrent, and wherein big slag inclusion impurity is well precipitated, and molten aluminium forms the current stabilization state and enters the cast operation simultaneously; Each in addition milling train starts when producing, needn't change ceramic filter plate 1, lifting mechanism will rotate getter 4 and graphite rotator 8 proposes molten aluminium, opening on the artificial then close gland 7, because refractory materials insulating interlayer 11, shell 12 make molten aluminium that insulation effect preferably be arranged, make in-house molten aluminium insulation to outlet with heating medium to inlet and B at A.
