Technical field
The utility model relates to electric furnace, more particularly, relates to a kind of water cooled furnace wall of electric furnace, this water cooled furnace wall can avoid its oxygen that is gone out by oxygen lance spraying rise dissolve.
Background technology
See also shown in Figure 1ly, generally all have an installing hole 11 on the water cooled furnace wall 10 of electric furnace 1, installing hole 11 outsides are provided with an oxygen rifle installing rack 12, are used to install multifunctional oxygen lance 2, by carrying out oxygen furnace steel in 2 pairs of stoves of this oxygen rifle.In the bottom of installing hole 11 are water cooled furnace walls 10 of electric furnace, and please in conjunction with shown in Figure 2, this water cooled furnace wall 10 is to adopt high-pressure boiler tube 101 manufacturings of solid matter to form, and is connected with cooling water in boiler tube 101, when high temperature is made steel, cooling effect is played in the furnace wall.Because oxygen rifle 2 tilts to install, the angle of itself and horizontal plane is 40 °, and ejection is boundling, the oxygen of not dispersing, therefore, when the Oxygen Flow of the high-voltage high-speed that sprays runs into the heavy scrap 3 that is positioned at 2 mouthfuls in oxygen rifle in the electric furnace 1, can cause the Oxygen Flow bounce-back to refract to (dotted arrow of Fig. 1 is the refractive direction of Oxygen Flow) on the water cooled furnace wall 10 that is arranged in installing hole 11 bottoms, cause boiler tube 101 fusings of water cooled furnace wall 10, cause taking place drainage, in case water cooled furnace wall 10 is impaired when comparatively serious, can cause a large amount of cooling waters to enter in the stove, cause that finally the anti-material in the stove damages, even the serious security incident that molten steel explodes takes place, thereby cause enormous economic loss.
The utility model content
Water cooled furnace wall at the above-mentioned oxygen rifle below that exists in the prior art is easily impaired, cause leaking and easily cause the shortcoming of molten steel blast, the purpose of this utility model provides a kind of water cooled furnace wall of electric furnace, the oxygen rifle that this water cooled furnace wall can be avoided being gone out by oxygen lance spraying dissolves, and prevents to cause the interior molten steel of stove to explode because of leaking.
For achieving the above object, the utility model adopts following technical scheme:
Have an installing hole on the water cooled furnace wall of this electric furnace, the installing hole outside is provided with oxygen rifle installing rack, on the water cooled furnace wall that is positioned at described installing hole lower end, be provided with retaining oxygen parts, these retaining oxygen parts comprise that framework, base of frame are connected with the top, water cooled furnace wall of installing hole lower end, framework lateral surface and one side, oxygen rifle installing rack lower end lean, and framework inside is filled out and is provided with resistant to elevated temperatures dnockout.
Also be connected with several in the described framework and hang muscle, hang muscle and be provided with hangnail.
The medial surface of described framework is the angle of inclination and is provided with.
The lateral surface of described framework also is provided with water-cooling channel, and water-cooling channel one side is connected with framework, and the water-cooling channel upper end offsets with oxygen rifle installing rack bottom, is respectively equipped with water inlet and delivery port on the water-cooling channel another side.
The bottom of this side one end of described water inlet and water-cooling channel is communicated with; The top of this side other end of described delivery port and water-cooling channel is communicated with.
In technique scheme, have an installing hole on the water cooled furnace wall of electric furnace of the present utility model, the installing hole outside is provided with oxygen rifle installing rack, on the water cooled furnace wall that is positioned at described installing hole lower end, be provided with retaining oxygen parts, these retaining oxygen parts comprise that framework, base of frame are connected with the top, water cooled furnace wall of installing hole lower end, framework lateral surface and one side, oxygen rifle installing rack lower end lean, and framework inside is filled out and is provided with resistant to elevated temperatures dnockout.After oxygen flow that oxygen lance spraying goes out runs into heavy scrap, directly refract on the retaining oxygen parts, it is impaired to avoid the water cooled furnace wall of installing hole lower end to dissolve, thereby has protected the water cooled furnace wall, prevents to cause because of leaking that molten steel explodes in the stove; , make it not easily broken and come off by but the anti-material of hanging in the muscle fixed frame is set; Can cool off retaining oxygen parts by water-cooling channel is set, prolong its service life.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also Fig. 3, shown in Figure 4, the water cooled furnace wall 20 of electric furnace of the present utility model is basic identical with prior art, adopts high-pressure boiler tube 201 manufacturings of solid matter to form equally, has an installing hole 21 on the water cooled furnace wall 20, installing hole 21 outsides are provided with oxygen rifle installing rack 22, are used to install multifunctional oxygen lance 2.Different is, on the water cooled furnace wall 20 that is positioned at installing hole 21 lower ends, have additional retaining oxygen parts 23, these retaining oxygen parts 23 comprise that framework 231, this framework 231 adopt the steel construction welding production, and 20 tops, water cooled furnace wall of the bottom of framework 231 and installing hole 21 lower ends are connected to a fixed, the lateral surface of framework 231 and one side, oxygen rifle 2 installing racks, 22 lower ends lean, fill out in the inside of framework 231 and to be provided with anti-material, anti-material adopts the resistant to elevated temperatures dnockout that falls.In framework 231, also be welded with several and hang muscle 232, hang muscle 232 and be provided with hangnail, but hang anti-material in muscle 232 fixed frames 231, when steel-making, can make it not easily broken and come off by this.The medial surface of this framework 231 is the angle of inclination and is provided with, and on the lateral surface of this framework 231, also be provided with water-cooling channel 24, water-cooling channel 24 1 sides are connected with framework 231, water-cooling channel 24 upper ends and oxygen rifle 2 installing racks 22 bottoms offset, be respectively equipped with water inlet 241 and delivery port 242 on water-cooling channel 24 another sides, water inlet 241 is communicated with the bottom of water-cooling channel 24 these side one ends; And delivery port 242 is communicated with the top of water-cooling channel 24 these side other ends.
Please in conjunction with shown in Figure 5, during use, if when the Oxygen Flow of the high-voltage high-speed of multifunctional oxygen lance 2 ejection runs into the heavy scrap 3 that is positioned at 2 mouthfuls in oxygen rifle in the electric furnace, can take place to rebound and refract on the medial surface that keeps off 23 inclinations of oxygen parts (dotted arrow promptly is shown the refractive direction of Oxygen Flow among Fig. 5), because filling out, framework 231 inside established resistant to elevated temperatures dnockout, can be not impaired because of oxygen flow, thereby the water cooled furnace wall 20 of having avoided installing hole 21 lower ends is met oxygen and is dissolved, effectively reduce the fault rate of leaking, having stopped the interior molten steel of stove blasts, eliminated potential safety hazard, simultaneously, in water-cooling channel 24, feed cooling water, retaining oxygen parts 23 are cooled off by water inlet 241, and the principle of utilizing hot water to rise, by delivery port 242 hot water is discharged smoothly, thereby can prolong service life of retaining oxygen parts 23, guarantee the ordinary production of electric furnace, because the cooling water channel of this cooling duct and water cooled furnace wall 20 is separate, can cut off control respectively.In addition, the anti-material in the framework 231 can prolong its use mission by online spray repair.
