By adopting the water-cooled plate, splashing can be relieved; dead burning of a furnace lid and a furnace edge is removed; the duration of heat of the electric furnace is shortened; the energy is saved; and the cost is reduced.
Description
Technical field
The utility model belongs to field of metallurgy, relates to a kind of electric furnace and uses cooled plate, and specifically a kind of energy-saving electric furnace that can reduce power consumption, consumption of electrode is used cooled plate.
Background technology
At present, Electric furnace steel making factory produces the burden structure that adopts 60-40% steel scrap, 40-60% molten iron; Through mole oxygen rifle and three furnace wall fluidic oxygen guns in stove oxygen supply the time; Switch in the electric furnace stove through power supply system and to smelt; Melting electric consumption is up to 225kwh/t, and consumption of electrode is up to 1.2kg/t, so the electric furnace production cost is much higher than the converter smelting cost.
In the conventional ultra-high power electric arc furnace type of furnace, open bell and directly in stove, add steel scrap through the material basket.Fig. 1 is an oxygen rifle installation site synoptic diagram in the prior art.Among the figure; Body of heater 51, EBT zone 52; On body of heater 51 inwall circumference, begin by doorframe 6 positions; Be provided with 1# cooled plate 61,2# cooled plate 62,3# cooled plate 63,4# cooled plate 64,5# cooled plate 65,6# cooled plate 66,7# cooled plate 67,8# cooled plate 68,9# cooled plate 69 and 10# cooled plate 60 successively; Mole rifle 7 is arranged on 10# cooled plate 60 places, and 1# oxygen rifle 71,2# oxygen rifle 72,3# oxygen rifle 73 are separately positioned on 3# cooled plate 63,4# cooled plate 64 and 8# cooled plate 68 places, and each cooled plate all is vertically to arrange along body of heater 51 vertical directions.
In existing electric cooker structure, because the electric furnace molten bath is more shallow, after hot metal ratio increases; Three the Praxair fluidic oxygen guns in original furnace wall are big with mole rifle oxygen supply intensity, and after a large amount of molten iron added, reaction between carbon and oxygen was violent in the stove; Splash is serious; Bell and stove are serious along steel bonding, and cleaning bell and stove are long along the time, are unfavorable for the raising of electrosmelting rhythm on the contrary.Therefore, must undergo technological transformation, alleviate splash, shorten the electrosmelting time, the purpose of energy saving and cost lowering thereby reach to furnace equipment.
Summary of the invention
The purpose of the utility model provides a kind of energy-saving electric furnace and uses cooled plate, adopts this cooled plate can alleviate splash, eliminates bell and stove along steel bonding, shortens the electrosmelting time, energy saving and cost lowering.
The purpose of the utility model realizes through following technical scheme:
A kind of energy-saving electric furnace is used cooled plate, comprises water cooling tube, it is characterized in that: said water cooling tube comprises vertical component and bossing, and vertical component is arranged on the body of heater and along the body of heater vertical direction and vertically arranges; One group of bossing is arranged on the vertical component and to furnace body inside direction projection arrangements.
In the utility model, the height of said bossing is 550-600mm, and the width of bossing is 800-1000mm.One group of bossing is three.Bossing is arranged on the middle section of vertical component.Be provided with oxygen rifle mount pad at bossing.
The utility model is transformed the cooled plate of electric furnace system, by original whole be that vertical component changes one group of bossing that advances to the stove convex into, three Praxair carbon fluidic oxygen guns are installed in bossing; Shortened and the molten steel face between distance; Both guaranteed oxygen supply intensity, reduced splash in the stove, also reduced erosion the anti-material of furnace lining; Help stable the raising and smelt rhythm, improve electric furnace furnace life.
Compared with prior art, adopt this cooled plate can alleviate splash, eliminate bell and stove, shorten the electrosmelting time, energy saving and cost lowering along steel bonding.
