Abstract
The utility model relates to a single phase single electrode electric slag furnace with a lining, which belongs to an electric slag remelting device. The single phase single electrode electric slag furnace with a lining, which relates to the shape of a furnace cavity and a bottom electrode, is composed of a furnace body, the bottom electrode, a water tank with a water cooling bottom, etc. The utility model is characterized in that the furnace cavity of the furnace body forms a basin shape, namely, the ratio of the depth of the furnace cavity and the diameter of the furnace cavity is smaller than one; the bottom electrode is rolled and welded into three cylinders with the same axis but unequal diameters by three steel plates, the outermost cylinder forms an inverted cone shape, and the bottoms of the three cylinders are together welded on a T-shaped circular steel plate arranged on a furnace bottom; the steel plate on the furnace bottom is divided into two parts, and the two steel plates can be in a separate type. The utility model which has the advantages of simple structure, convenient maintenance, long service life, etc. is suitable for producing alloy steel with high quality.
Description
The utility model belongs to esr equipment in the field of metallurgy, relates to burner hearth shape and bottom electrode that single-phase one pole has the lining electroslag furnace, is applicable to the production superior alloy steel.
It is in the burner hearth of refractory material furnace lining is arranged that the steel-making of lining electroslag furnace is arranged, the slag thermal resistance that produces when utilizing electric current by liquid slag bath, metal charge fusion---comsumable melt, and carry out refining, to obtain high-quality molten steel, carry out ingot casting, foundry goods or from casting, a kind of method of refining of high-quality blank or finished product is provided, and being electroslag metallurgy changes into the new technology that the value row is paid attention to that the type direction develops to pure.
It is the subject matter that refining need solve that the life-span of lining electroslag furnace fire proof material of furnace lining and hearth electrode is arranged.Commonly used has lining electroslag furnace stove shape as shown in Figure 1, and wherein: 1 is fire proof material of furnace lining, and 2 is bottom electrode, and 3 is water tank at the bottom of the water-cooled.The shortcoming of this structure is: (1) burner hearth be shaped as straight garden tubular or up big and down small garden tubular, ratio＞1.5 of general furnace depth and internal diameter, though the cross-sectional area of burner hearth reduces, slag consumption and the loss of top of the slag radiations heat energy reduce, but in the electrode melting process, the slag erosion that refractory materials 1 is rotated is serious, has both used low fluorine slag, and lining life is also lower.(2) Chang Yong hearth electrode 2 is the garden steel about Φ 100～200mm, the slightly high 2～3mm of its aspect ratio furnace bottom thickness, hearth electrode and steel plate of furnace hearth are welded together, in the steelmaking process the body of heater seat on water tank at the bottom of the water-cooled 3, with water tank at the bottom of the water-cooled hearth electrode is cooled off.Because the electroslag smelting furnace temperature is higher, reaches between 1700～2000 ℃, often melt because of temperature is too high on bottom electrode top, if control bad enough molten steel that do not stay, next stove was often very difficult because of the obstructed striking of circuit when last stove was poured into a mould.Simultaneously, this structure bottom refractory is repaired after by etch very inconvenient.
The purpose of this utility model is to provide a kind of single-phase one pole simple in structure, easy to maintenance, long service life that the lining electroslag furnace is arranged.
Based on the foregoing invention purpose, the utility model by body of heater, bottom electrode, water-cooled at the bottom of water tank etc. form, its characteristics are: the burner hearth shape of (1) body of heater is peviform, promptly described furnace depth and diameter are than＜1; (2) to be welded into axis with three block plates volumes identical for described bottom electrode, three garden tubes that diameter does not wait, outmost garden tube is back taper, and the bottom is with being welded on the steel plate of furnace bottom T shape garden, come by refractory materials is isolated between three garden tubes, water tank cooling at the bottom of the water-cooled is arranged at electroplax bottom, the described end; (3) described steel plate of furnace hearth is divided into two, and two block plates are detachable, and wherein one is T shape garden plate, and another piece is with body of heater garden ring flat-plate welded together, and T shape garden panel seat is common formation steel plate of furnace hearth on the ring flat-plate of garden.
The thickness of three blocks of garden tube steel plates of described bottom electrode is 10～20mm.
Compared with prior art, advantage of the present utility model is:
(1), the utility model design peviform burner hearth, be furnace depth and diameter ratio＜1, in the smelting process, molten steel and slag weaken washing away significantly of refractory wall, and lining life obviously improves, in order to reduce slag surface heat radiation loss as far as possible, mixed slag charge adds in the stove gradually, and the slag upper surface remains not molten state in smelting process, though because the crucible diameter increasing, the slag consumption has increase slightly, but has made things convenient for the effect of adding cold burden and having strengthened the slag cleaning molten steel.
(2), adopt the utility model bottom electrode structural, because the center of resembling not is that the bottom electrode heat of Φ 100～200mm garden steel is so concentrated, so in smelting process, be difficult for fusing, refractory materials around the electrode is not fragile, in addition, because spreading area is bigger, in stove after the cast, only need stay a little molten steel, the very easy conducting of circuit during next stove starting the arc.
(3), leave sufficient space between three blocks of garden tube steel plates of bottom electrode, the ramming refractory materials is very convenient, and ramming gets solid, has increased the work-ing life of furnace bottom furnace lining.
(4), steel plate of furnace hearth be two detachable, bottom electrode is a back taper, if furnace bottom damages, only needs the left-hand thread body of heater, furnace bottom T shape garden plate is got renewal, and the furnace lining periphery can not damage, is convenient to maintenance and uses.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of facing that the lining electroslag furnace is arranged commonly used in the prior art.
Fig. 2 has the structural representation of facing of lining electroslag furnace for the utility model.
Fig. 3 is that the utility model A is to schematic top plan view.
Among Fig. 1,1 is fire proof material of furnace lining, and 2 is bottom electrode, and 3 is water tank at the bottom of the water-cooled.
Among Fig. 2, Fig. 3,1,2,3 is three garden steel cylinders of bottom electrode, and 4 is fire proof material of furnace lining, and 5 is furnace bottom T shape garden steel plate, and 6 are furnace bottom garden ring steel plate, and 7 is water tank at the bottom of the water-cooled, and 8 is burner hearth, and 9 is body of heater.
Claims (2)
