Abstract
The invention discloses an electric-arc furnace electrode clamping device which can prevent an electrode from being oxidized before the electrode is put into an electric-arc furnace. The electric-arc furnace electrode clamping device comprises a support ad a clamping ring arranged on the support, wherein the electrode is arranged in the clamping ring in a sleeved mode, an electrode cooling device is arranged under the clamping ring and is a circle of annular water pipe with which the electrode is annularly sleeved, multiple water spraying holes facing the electrode are formed in the annular water pipe, and the annular water pipe is communicated with a water pump. Due to the fact that the electrode cooling device is arranged, after the electrode is put into the clamping ring, the annular water pipe can be opened to perform electrode spraying so as to prevent the electrode from being oxidized before the electrode is put into a furnace body, unnecessary oxidation loss can be prevented, and the service life of the electrode is greatly prolonged.
Description
Technical field
The present invention relates to a kind of clamp structure, especially relate to a kind of arc furnace electrode clamping device.
Background technology
At present, the work of arc furnace starts hole at the furnace roof of arc furnace, and arrange support above furnace roof, and support is provided with electrode collar, and electrode is inserted and entered in body of heater by the furnace roof hole of arc furnace and works from electrode collar.Due to electrode surface extreme temperatures, time above body of heater, easily cause the oxidation of electrode surface, thus affect the normal work of electrode after causing electrode to enter body of heater, also greatly can reduce the useful life of electrode simultaneously.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of electrode that can prevent to enter the front arc furnace electrode clamping device that oxidation occurs of arc furnace.
The technical solution adopted for the present invention to solve the technical problems is: arc furnace electrode clamping device, comprise support and be arranged on the holding ring on support, electrode is set with in holding ring, electrode cooling device is provided with below holding ring, described electrode cooling device is the circle annular conduit of ring set on electrode, annular conduit offers multiple hole for water spraying towards electrode, and described annular conduit is communicated with water pump.
Further, electrode side is provided with the temperature sensor be fixed on support, and described temperature sensor is electrically connected with controller, and controller is electrically connected with described water pump.
Further, holding ring is provided with the flexible protective gasket ring arranged around holding ring.
The invention has the beneficial effects as follows: this arc furnace electrode clamping device, due to the setting of electrode cooling device, after electrode enters into holding ring, annular conduit can be opened spray electrode, thus prevent electrode oxidized before entering body of heater, thus unnecessary oxidation loss can be prevented, greatly improve the useful life of electrode.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, Reference numeral is: support 1, holding ring 2, electrode 3, annular conduit 4, water pump 5, temperature sensor 6, controller 7, flexible protective gasket ring 8.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
As shown in Figure 1, arc furnace electrode clamping device of the present invention, comprise support 1 and be arranged on the holding ring 2 on support 1, electrode 3 is set with in holding ring 2, electrode cooling device is provided with below holding ring 2, described electrode cooling device is the circle annular conduit 4 of ring set on electrode 3, and annular conduit 4 offers multiple hole for water spraying towards electrode 3, and described annular conduit 4 is communicated with water pump 5.Due to the setting of electrode cooling device, after electrode 3 enters into holding ring 2, annular conduit 4 pairs of electrodes 3 can be opened and spray, thus prevent electrode 3 oxidized before entering body of heater, thus unnecessary oxidation loss can be prevented, greatly improve the useful life of electrode.Adopt which, after electrode 3 enters into holding ring 2, can start water pump and pass into water under high pressure in annular conduit 4, water under high pressure is sprayed water to electrode 3 by the hole for water spraying that annular conduit 4 is offered, and reaches the object reducing electrode surface temperature.In this approach, be preferably vaporific from the water of hole for water spraying ejection, be more conducive to the temperature reducing electrode 3 surrounding enviroment, reach the object better preventing electrode 3 to be oxidized.
In order to better control electrode 3 enters the temperature before body of heater, electrode 3 side is provided with the temperature sensor 6 be fixed on support 1, and described temperature sensor 6 is electrically connected with controller 7, and controller 7 is electrically connected with described water pump 5.The temperature feedback recorded by temperature sensor 6 is to controller 7, when the needs that electrode temperature reaches setting carry out above the temperature that cools, controller 7 water supply pump 5 one signals, water pump 5 works and water is delivered to annular conduit 4 pairs of electrodes 3 cools, which can the surface temperature of better control electrode 3, reaches the object better preventing electrode 3 to be oxidized.
In the prior art, holding ring 2 is all the clamping device of a rigidity, when electrode 3 is by holding ring 2; easily cause the surface tear of electrode and fracture; therefore, as preferred embodiment, holding ring 2 is provided with the flexible protective gasket ring 8 arranged around holding ring.The setting of flexible protective gasket ring 8, effectively can prevent the scuffing on electrode 3 surface, can reduce the probability of damage of electrode 3 further.
