Abstract
The invention discloses a special aluminum melting furnace. The special aluminum melting furnace comprises a furnace casing, a furnace core arranged in the furnace casing and an inductor arranged on the outer ring of the furnace core. A graphite crucible is used as the furnace core, and a liquid outlet is arranged on the lower side surface of the furnace core. The inductor is formed through the welding of a main wire turn at the upper middle part of the furnace core and an auxiliary wire turn at the lower part of the furnace core, and the wire diameter of the auxiliary wire turn is 1.2-1.6 times of that of the main wire turn. The auxiliary wire turn is arranged on the liquid outlet in a gate-shaped structure. A molten aluminum covering agent alway covers the surface of molten aluminum in the whole melting process, and the liquid outlet arranged at the bottom is matched with the inductor, thereby enabling the bottom temperature to meet production requirements. Meanwhile, energy is saved.
Description
Technical field
The present invention relates to a kind of molten aluminium stove, particularly relate to a kind of extraordinary molten aluminium stove.
Background technology
At present, aluminium alloy chip, sawdust is seldom recovered utilization, and reason is in existing melting furnace, and broken aluminium bits are very easily oxidized.For head it off, Shanghai Communications University finds out a set of anti-oxidation technique, the rate of recovery can reach 98%, this technological requirement adds special coverture on melt surface, when going out aluminium liquid, coverture will cover aluminium liquid always, though this technique is good, but existing melting unit does not reach the requirement of this technique, in order to make this kind of technique be produced in batches, a kind of novel melting unit just must be innovated.
Summary of the invention
For overcoming the defect of prior art, the object of the present invention is to provide a kind of extraordinary molten aluminium stove.
For achieving the above object, the technological means that the present invention takes is: extraordinary molten aluminium stove, and comprise furnace shell, the combustion chamber be arranged in furnace shell, be arranged on the inductor of combustion chamber outer ring, described combustion chamber is graphite crucible, and the downside of combustion chamber is provided with liquid outlet; Described inductor is welded to form by being positioned at the main line circle at middle part and the by-pass circle of bottom on combustion chamber, and wherein the wire diameter of by-pass circle is 1.2-1.6 times of main line circle wire diameter; Described by-pass circle is positioned on liquid outlet with portal structures at liquid outlet.
Further, described main line circle, by-pass circle all select copper pipe, and by-pass circle selects two circles.
The invention has the beneficial effects as follows: make aluminium liquid coverture in whole fusion process, cover aluminium liquid surface all the time, the cooperation of the liquid outlet that bottom is arranged and inductor, makes bottom temp meet production requirement, save the energy simultaneously.
Accompanying drawing explanation
Below in conjunction with view and embodiment, the present invention is described in detail.
Fig. 1 is structural representation of the present invention.
In figure: 1, inductor, 2, combustion chamber, 3, liquid outlet.
Detailed description of the invention
Special type as shown in Figure 1 melts aluminium stove, and comprise furnace shell, the combustion chamber 2 be arranged in furnace shell, be arranged on the inductor 1 of combustion chamber outer ring, described combustion chamber 2 is graphite crucible, and the downside of combustion chamber 2 is provided with liquid outlet 3; Described inductor 1 is welded to form by being positioned at the main line circle at middle part and the by-pass circle of bottom on combustion chamber 2, and wherein the wire diameter of by-pass circle is 1.2-1.6 times of main line circle wire diameter; Described by-pass circle is positioned on liquid outlet 3 with portal structures at liquid outlet 3.
Further, described main line circle, by-pass circle all select copper pipe, and by-pass circle selects two circles.
The liquid outlet 3 that side is opened bottom graphite crucible, discharges the aluminium liquid melted, so just makes coverture cover above aluminium liquid always.Owing to making aluminium liquid charged to prevent aluminium liquid from sticking on inductor, the danger of electric shock is brought to operating personnel, so can not inductor be had below liquid outlet, but bottom graphite crucible, there is the height of 10cm there is no inductor from liquid outlet is suitable for reading, temperature of aluminum liquid can be caused to reduce or solidify, enough high for ensureing bottom temperature of aluminum liquid, so adopt bottom two circle induction coil copper pipe wire diameter to become large, make bottom also have induction coil, strengthen induction.As certain type melts in aluminium stove, inductor diameter phi 680mm, main line circle adopts copper pipe 25 × 35 main around 18 circles, and by-pass circle adopts 30 × 50 copper pipe 2 circles, graphite crucible external diameter φ 530mm, internal diameter φ 470mm, high 725mm, makes aluminium liquid coverture in whole fusion process, cover aluminium liquid surface all the time, the cooperation of the liquid outlet that bottom is arranged and inductor, make bottom temp meet production requirement, save the energy simultaneously.
The above, be the specific embodiment of the present invention, be not limited thereto, and is anyly familiar with those skilled in the art in the technical scope that the present invention shows, can expect the mode changing or replace easily, all should be encompassed within protection scope of the present invention.
Claims (2)
1. extraordinary molten aluminium stove, comprise furnace shell, the combustion chamber (2) be arranged in furnace shell, be arranged on the inductor (1) of combustion chamber outer ring, it is characterized in that: described combustion chamber (2) is graphite crucible, the downside of combustion chamber (2) is provided with liquid outlet (3); Described inductor (1) is welded to form by being positioned at the main line circle at middle part and the by-pass circle of bottom on combustion chamber (2), and wherein the wire diameter of by-pass circle is 1.2-1.6 times of main line circle wire diameter; Described by-pass circle is positioned on liquid outlet (3) with portal structures at liquid outlet (3).
