A furnace lining and a furnace shell are arranged on the ground; a high-level steel platform parallel with the ground is provided with an electrode lifting device vertical to the furnace body; the electrode is arranged in the electrode lifting device and stretches into a furnace material of a furnace body; and the electrode is connected with a transformer through a short net and a rectifier. The high-power rectangular DC submerged arc furnace, disclosed by the utility model, has the advantages of increasing capacity by 3-6 times without adding the diameter of the electrode, being simple in structure, easy to manufacture and convenient to popularize, further improving capacity of the submerged arc furnace, adding heat efficiency, saving energy obviously, simplifying structure, reducing manufacturing cost and prolonging service life.
Description
Technical field
The utility model relates to the DC-ore-heating furnace of a kind of ferroalloy, calcium carbide electric furnace, particularly a kind of high-power rectangle DC-ore-heating furnace.
Background technology
China's ferroalloy, the hot stove in the employed ore deposit of calcium carbide industry nearly all use the interchange three-phase electrode at present, and the type of furnace is circular.The hot stove in these ore deposits is influenced by reactance, the eddy current of alternating current, the kelvin effect of low power factor, and the restriction of three electrode diameters, and capacity is difficult to do more, and cost of manufacture is very high, manufacture difficulty is very big.
The utility model content
The utility model technical problem to be solved be to provide the hot heat size in a kind of ore deposit big, simple in structure, more energy-conservation, make to be easy to high-power rectangle DC-ore-heating furnace.
In order to solve above technical problem; The utility model provides a kind of high-power rectangle DC-ore-heating furnace; Furnace lining, furnace shell are installed on ground, on the high-order steel platform parallel to the ground electrode lifting device perpendicular to body of heater are installed, and electrode is installed in the electrode lifting device; And stretch in the furnace charge of body of heater, electrode is connected with transformer through short net, rectifier.
The quantity of said electrode is the 4-8 bar, by the power supply of 2-4 cover continuous-current plant.
Two at said electrode is one group, in stove, divides two row's symmetric arrangement, and every group of electrode supplied power by the continuous-current plant of a correspondence.
Said furnace lining is installed in the furnace shell, and both are rectangle at shape.Furnace lining does not have the function of hearth electrode.
The beneficial effect of the utility model is:
1) the hot heat size in this ore deposit is under the situation that does not increase electrode diameter, and capacity has increased by 3～6 times, and is simple in structure, make easily, be convenient to promote;
2) further improve the hot heat size in ore deposit, increase the thermal efficiency, simplified structure, reduction cost of manufacture, increase the service life;
3) the hot stove in this ore deposit do not have eddy current, do not have reactance, do not have kelvin effect, no hearth electrode, High Power Factor, no circuit noise significantly reduces electric energy loss.

The specific embodiment
See also shown in the accompanying drawing, the utility model is done further to describe.
The utility model provides a kind of high-power rectangle DC-ore-heating furnace; Furnace lining 5, the furnace shell 6 of rectangle are installed on ground; On the high-order steel platform 9 parallel to the ground electrode lifting device 8 perpendicular to body of heater is installed; Electrode 1 is installed in the electrode lifting device 8, and stretches in the furnace charge 2 of body of heater, and electrode is connected with transformer 4 through weak point net 2, rectifier 3.
The quantity of said electrode 1 is the 4-8 bar, by the power supply of 2-4 cover continuous-current plant.
1 two at said electrode is one group, in stove, divides two row's symmetric arrangement, and every group of electrode 1 supplied power by the continuous-current plant of a correspondence.
The high-power rectangle DC-ore-heating furnace of the utility model, employed furnace lining 5 does not have the function of hearth electrode.
The high-power rectangle DC-ore-heating furnace of the utility model; Changed the capacity limit and the electrode diameter restriction of the hot stove in three-phase alternating current ore deposit in the past; Under the situation that does not have to change at electrode diameter, capacity has but increased by 3～6 times, and the making and the operating cost of high-power rectangle DC-ore-heating furnace obviously reduce; Energy-saving effect is obvious, is fit to very much the popularization and the use of large and medium-sized smelting mine heat furnace.
