Abstract
The invention discloses an electric arc furnace electrode clamping device, and can prevent an electrode from oxidization before entering into an electric arc furnace. The electric arc furnace electrode clamping device includes a support and a clamping ring arranged on the support, an electrode is sleeved in the clamping ring, a lower surface of the clamping ring is fixedly provided with an annular circulating water cooling chamber, the circulating water cooling chamber is communicated with a water pump, the electrode is located in the annular circulating water cooling chamber, and the lower end of the electrode extends out of the circulating water cooling chamber. Due to the arrangement of the circulating water cooling chamber, when the electrode enters in to the clamping ring, the circulating water cooling chamber can be started to cool the electrode, thereby preventing the electrode from oxidization before entering into a furnace body, preventing unnecessary oxidization loss, greatly prolonging the service life of the electrode, the circulating water cooling chamber can also save water, and water is prevented from splashing into the electric arc furnace and affecting steelmaking operation of the electric arc furnace.
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, the circulating water chamber of annular is fixedly installed at holding ring lower surface, described circulating water chamber has water pump, electrode is positioned at the circulating water chamber of annular, and circulating water chamber is extended in the lower end of electrode.
Further, electrode side is provided with the temperature sensor be fixed on support, and temperature sensor is positioned at below circulating water chamber, 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 circulating water chamber, after electrode enters into holding ring, electrode can be cooled ON cycle water cooling chamber, thus prevent electrode oxidized before entering body of heater, thus unnecessary oxidation loss can be prevented, greatly improve the useful life of electrode, and all right using water wisely of circulating water chamber, prevent the steelmaking operations affecting arc furnace in water projection to arc furnace.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, Reference numeral is: support 1, holding ring 2, electrode 3, circulating water chamber 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, the circulating water chamber 4 of annular is fixedly installed at holding ring 2 lower surface, described circulating water chamber 4 is communicated with water pump 5, and electrode 3 is positioned at the circulating water chamber 4 of annular, and circulating water chamber 4 is extended in the lower end of electrode 3.Due to the setting of circulating water chamber 4, after electrode 3 enters into holding ring 2 and enters into circulating water chamber 4, can cool by ON cycle water cooling chamber 4 pairs of electrodes 3, thus prevent electrode 3 oxidized before entering body of heater, thus unnecessary oxidation loss can be prevented, greatly improve the useful life of electrode; And adopt circulating water chamber 4 pairs of electrodes 3 to cool, and can using water wisely, the steelmaking operations affecting arc furnace in water projection to arc furnace can also be prevented.
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 temperature sensor 6 is positioned at below circulating water chamber 4, 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 circulating water chamber 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.
