Abstract

The utility model relates to a melting furnace, which comprises a flowing furnace and a maintaining furnace, wherein, the lower part of the flowing furnace is provided with two melting channel of which the middle part is provided with an iron core, a primary coil and a water jacket. A passage is arranged between the flowing furnace and the maintaining furnace, and the passage contains an annular melting channel; moreover, one side of the passage is communicated with the lower part of a furnace hearth of the melting furnace, and the other side of the passage is communicated with the lower part of a furnace hearth of the maintaining furnace; the middle part of the annular melting channel is provided with an iron core, a primary coil, and a water jacket. The melting furnace with the structure has the advantages that the melting efficacy is high, the process of work always keeps three-phase equilibrium, the accident of breaking off channels can be avoided when the furnace is restarted after stopped, and the utility model has a favorable energy-saving effect.

Description

Smelting furnace

The utility model relates to a kind of smelting furnace of production of copper bar.

Chinese patent CN2101203U discloses a kind of symmetrical expression line-frequency induction combination smelting furnace of producing oxygen-free copper bar, this stove is because the channel of its holding furnace has half the time is to be in off-position, thereby influence its melting capacity and three-phase equilibrium time, cause melting efficiency low, can not remain three-phase equilibrium.

The purpose of this utility model provides a kind of melting efficiency height, and the course of work remains the smelting furnace of three-phase equilibrium.

The technical scheme that realizes above-mentioned purpose is: a kind of smelting furnace, have melting furnace and holding furnace, the melting furnace bottom has two channels, the centre of channel has iron core, primary winding and water jacket, has passage between melting furnace and the holding furnace, this passage contains an annular channel, and a side of this passage communicates with the lower furnace portion of melting furnace, and opposite side communicates with the lower furnace portion of holding furnace; The centre of this annular channel also has iron core, primary winding and water jacket.

After adopting technique scheme, owing to have passage between melting furnace and the holding furnace, this passage contains an annular channel, and a side of this passage communicates with the lower furnace portion of melting furnace, opposite side communicates with the lower furnace portion of holding furnace, the centre of this annular channel also has iron core, primary winding and water jacket, therefore, when melting furnace is worked, the annular channel forms secondary coil, and the copper material in the passage melts under the high temperature that annular channel produces, thereby melting furnace is communicated with holding furnace, half of annular channel participates in the fusing of melting furnace, second half participates in the insulation of holding furnace, also is that annular channel is in "on" position all the time, like this, the melting efficiency height of melting furnace, and the course of work is in the three-phase equilibrium state all the time.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model smelting furnace;

Fig. 2 is the cutaway view Amplified image along the A-A line of Fig. 1.

As shown in Figure 1, 2, a kind of smelting furnace, have melting furnace 1 and holding furnace 3, melting furnace 1 bottom has two channels 2, the centre of channel 2 has iron core 6, primary winding 7 and water jacket 8, has passage 4 between melting furnace 1 and the holding furnace 3, and this passage 4 contains an annular channel 5, and a side of this passage 4 communicates with the lower furnace portion of melting furnace 1, and opposite side communicates with holding furnace 3 lower furnace portion; The centre of this annular channel 5 also has iron core 6, primary winding 7 and water jacket 8.

As shown in Figure 2, holding furnace 3 bottom-hinged have hydraulic cylinder 10, and hydraulic cylinder 10 lower ends and bearing 9 are hinged, and melting furnace 1 bottom and bearing 9 are hinged.After adopting this structure,, can make holding furnace promote certain altitude, make mould 11 be in the top of copper liquid level, prevent that copper liquid runs off, and is convenient for changing mould 11 simultaneously at bleedout and more during mold exchange 11.

Annular channel 5 of the present utility model has a half-power heat tracing stove 3, and second half power heats copper liquid in the melting furnace 1 with melting furnace 1 interior two channels 2, thereby avoids causing oxygen uptake and heat-energy losses by melting furnace 1 when holding furnace 3 is transported the copper liquid.Simultaneously, two channels 2 and annular channel 5 all can be operated at full capacity, form three-phase equilibrium.In addition, the existence of annular channel 5, for after the blowing out once more blow-on created very advantageous conditions, disconnected ditch accident takes place in the time of can avoiding blow-on again, has good energy-saving effect.
