Abstract
The utility model provides a spiral water-cooled copper sleeve for a bottom electrode of an electric furnace. The spiral water-cooled copper sleeve is characterized by comprising a spiral water-cooled copper sleeve body, a ring-shaped plane is formed at one end of the spiral water-cooled copper sleeve body, and a plurality of spiral grooves are formed on the outer wall of the spiral water-cooled copper sleeve body. The spiral water-cooled copper sleeve provided by the utility model has the advantages of better cooling effect and electric conductivity, simple structure and convenience in installation.
Description
Technical field
The utility model relates to a kind of electric furnace hearth electrode and uses the spiral water cooling copper sleeve, utilizes the electric conductivity and the spiral bosh of spiral water cooling copper sleeve, reaches conduction and cooling effect.
Background technology
Along with the stable development of the technological in the ascendant and ac arc furnace steel-smelting technology of dc arc furnace, further improving electric arc furnace smelting efficient is a problem that has important practical significance with improving the power quality problem that is caused thus.The developing history of direct current stove, the also developing history of hearth electrode just to a great extent.According to the pattern of hearth electrode, at present the direct current stove is divided into three types usually, promptly conducts electricity four kinds of furnace bottom formulas, water cooled steel bar type, many draw points formula, many steel discs formula.Direct current electric arc furnace water cooled steel bar type hearth electrode technology comprises the hot state of hearth electrode, state of insulation, hearth electrode sleeve brick and water-cooled cyclic part.The shortcoming of existing hearth electrode assembly is that complex structure, poor electric conductivity, cooling effect are poor.
Summary of the invention
The purpose of the utility model provides a kind of electric furnace hearth electrode simple in structure, that have higher electric conductivity and water-cooled performance and uses the spiral water cooling copper sleeve.
In order to achieve the above object; The utility model provides a kind of electric furnace hearth electrode to use the spiral water cooling copper sleeve, it is characterized in that, comprises spiral water cooling copper sleeve body; Spiral water cooling copper sleeve body one end has the annular plane, and the outer wall of spiral water cooling copper sleeve body is provided with many helicla flutes.
Preferably, described annular plane is provided with and installs and fixes screw and insulation fixed via.
Preferably, described annular plane is provided with survey hole of thermocouple.
Compared with prior art, the utility model has the advantages that:
1, have unique T shape design, the annular plane of super large can increase conductive area and thermal conductivity, and electric conductivity reaches 48m/ mm2, thermal conductivity 322W/mk.
2, the helicla flute that has the super large helical pitch, every helicla flute all has independently circulation waterway, and film-cooled heat reaches more than 85%, good cooling results;
3, have survey hole of thermocouple, thermometric rate of accuracy reached to 95%, through temperature control, the recirculated water incrustation scale that can not produce electrolysis improves the life cycle of equipment greatly, and safety in production provides safeguard.
4, simple in structure, easy for installation.
Description of drawings
Fig. 1 for the electric furnace hearth electrode with spiral water cooling copper sleeve structural representation.
The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1; For the electric furnace hearth electrode with spiral water cooling copper sleeve structural representation; Described electric furnace hearth electrode comprises spiral water cooling copper sleeve body 5 with the spiral water cooling copper sleeve, and spiral water cooling copper sleeve body 5 one ends have annular plane 6, and the outer wall of spiral water cooling copper sleeve body 1 is provided with many helicla flutes 4.Described annular plane 6 is provided with and installs and fixes screw 2 and insulation fixed via 3.Described annular plane 6 is provided with survey hole of thermocouple 1.
Described spiral water cooling copper sleeve body 5 adopts Tu2 through repeatedly forging die-forging forming, installs and fixes screw 2 and is used for spiral water cooling copper sleeve body 5 is fixed on the electric furnace bottom with insulation fixed via 3, and survey hole of thermocouple 1 is used to install thermocouple, measures temperature in real time.
The utility model mainly utilizes the electric conductivity and the special spiral cooling effect of water-cooling spiral copper sheathing, and the heat energy that the electric furnace hearth electrode is produced is taken away through cycle of higher pressure water, reaches conduction and cooling effect.Through the insulation fixing hole this product is fixed on the electric furnace bottom, forms a cover circulation waterway with miscellaneous part again, reach conduction and cooling effect.
