Abstract
Disclosed is an arc furnace electrode cooling device with excellent cooling effect, comprising an electrode (4), wherein the periphery of the electrode (4) is provided with an annular shower pipe (3) connected with a water inlet tube (1); the annular shower pipe (3) is provided with water outlet holes (5) at the side closing to the electrode; and the water outlet holes (5) are annularly arranged around the electrode (4) in the radial direction of the annular shower pipe (3). The arc furnace electrode cooling device is characterized in that the water inlet tube (1) is connected with an air inlet pipe (2) and each water outlet hole (5) is provided with an atomizing nozzle (6). The arc furnace electrode cooling device has a simple structure. When the arc furnace electrode cooling device is used, due to the combination of the water and gas, the simple water spraying is turned into the aerosol spraying, thereby forming strong aerosol mass at the atomizing nozzles which plays a role in both cooling and sealing the electrode and the furnace lid. The arc furnace electrode cooling device prevents the overflow of the high temperature furnace gas, facilitates the protection of the atmosphere inside the furnace, and prolongs the service lifetime of the furnace lid. The trial proves that the electrode consumption is decreased to 3.1Kg/ton of steel from the 3.2Kg/ton of steel, thereby having remarkable economic benefits.
Description
Technical field
The utility model relates to a kind of arc furnace, specifically a kind of arc furnace electrode cooling device.
Background technology
At present, electric-arc furnace steelmaking produces electric arc by electrode raw material is heated, and its temperature can reach more than 2000 ℃, in order to reduce the temperature of electrode, reduce the oxidation of electrode, improve the useful life of electrode, usually in the junction of electrode and bell, cooling device is installed.Namely add a circle stainless steel waterpipe around the electrode, water pipe is at the aperture that by the electrode one many diameters of sidetracking is 2 ㎜ left and right, with water under high pressure spray cooling down on electrode.The shortcoming that this cooling device exists has 1, in the situation that the hydraulic pressure shakiness, water can not be sprayed onto on electrode, export license is fast; 2, aperture can not form water smoke, and cooling of electrode is inhomogeneous, not thorough; The residual water of 3, shutting down in rear water pipe can not be discharged immediately, and water clock affects the bell life-span on bell; 4, do not become sealing between electrode and bell.
Summary of the invention
The purpose of this utility model is to provide a kind of arc furnace electrode cooling device of good cooling results.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of arc furnace electrode cooling device, it comprises electrode, be provided with the ring-type shower that is communicated with water inlet pipe around electrode, be provided with apopore by electrode one side on the ring-type shower, apopore in the upwards setting circlewise of the footpath of ring-type shower, is connected with air inlet pipe around electrode on water inlet pipe, apopore is provided with atomizer.
Apopore described in the utility model is two the ring-type shower in the radial direction, and the angle of the center line of two apopores is 60 °～120 °.
Owing to adopting technique scheme, the utility model has been realized goal of the invention preferably, and it is simple in structure, during use, due to mixing of gas and water, the pure water spray becomes spray washing, the atomizer place forms powerful aerosol group, has both played cooling effect, has played again the sealing function of electrode and bell, prevent the excessive of high-temperature furnace gas, be conducive to keep the atmosphere in stove, improve the bell life-span, through on probation, consumption of electrode drops to 3.1Kg/ ton steel by original 3.2Kg/ ton steel, and economic effect is obvious.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of ring-type shower 3.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As seen from Figure 1, Figure 2, a kind of arc furnace electrode cooling device, it comprises electrode 4, be provided with the ring-type shower 3 that is communicated with water inlet pipe 1 around electrode 4, be provided with apopore 5 by electrode one side on ring-type shower 3, apopore 5 in the upwards setting circlewise of the footpath of ring-type shower 3, is connected with air inlet pipe 2 around electrode 4 on water inlet pipe 1, apopore 5 is provided with atomizer 6.
Apopore 5 described in the utility model is two ring-type shower 3 in the radial direction, and the angle of the center line of two apopores 5 is 60 °～120 ° (the present embodiment is 90 °).
When the utility model was used, the inlet pressure of air inlet pipe 2 was 0.6MPa, and for increasing cooling effect, apopore 5 is two ring-type shower 3 in the radial direction, and the angle of the center line of two apopores 5 is 90 °.Like this, apopore 5 is arranged on ring-type shower 3 around 4 one-tenth two ring-types of electrode.Gas by atomizer 6 ejections on ring-type shower 3, carries out comprehensive cooling to electrode 4 with after water mixes.Because, pure water spray becomes spray washing, the atomizer place forms powerful aerosol group, has both played cooling effect, has played again the sealing function of electrode 4 with bell.
When the utility model is used, can also be provided with electromagnetically operated valve on water inlet pipe 1 and air inlet pipe 2, can control by electromagnetically operated valve the amount that enters the interior gas of ring-type shower 3 and water.
Claims (2)
1. arc furnace electrode cooling device, it comprises electrode (4), electrode (4) is provided with the ring-type shower (3) that is communicated with water inlet pipe (1) on every side, ring-type shower (3) is upper is provided with apopore (5) by electrode one side, apopore (5) makes progress in the footpath of ring-type shower (3) around electrode (4) and arranges circlewise, it is characterized in that being connected with air inlet pipe (2) on water inlet pipe (1), apopore (5) is provided with atomizer (6).
2. arc furnace electrode cooling device according to claim 1, it is characterized in that described apopore (5) ring-type shower (3) be two in the radial direction, the angle of the center line of two apopores (5) is 60 °～120 °.
