Abstract
Description
Technical Field
[0001] The utility model relates to the field of ferrosilicon alloys, and particularly relates to a slag discharge pit for ferrosilicon alloy materials. Background Art
[0002] During the process of producing ferrosilicon alloy in a submerged arc furnace, waste slag floats on the surface of molten steel, and there will also be waste slag on the upper surface of the ladle when it transports and holds the ferrosilicon alloy from the submerged arc furnace. These waste slags affect the quality of the ferrosilicon alloy during subsequent casting and forming, so it is necessary to remove the floating slag on the surface of the ladle.
[0003] When removing, the crane moves the ladle to the slag discharge pit, and the operator holds a slag raking rod to rake the waste in the ladle into the slag discharge pit. However, due to the high temperature of the ladle, the radiation to the operator is large, and during slag raking, the molten steel is also likely to splash outwards, affecting the safety of the staff. Summary of the Utility Model
[0004] In order to solve the above existing problems, the utility model provides a slag discharge pit for ferrosilicon alloy materials.
[0005] The utility model is realized through the following technical solutions:
[0006] A slag discharge pit for ferrosilicon alloy materials includes a slag discharge pit and a retaining wall arranged on its upper part. A sliding base is slidably connected to the upper part of one side of the retaining wall. A blocking plate is fixed on the sliding base. A slag raking opening is formed on the blocking plate. A rotating guide wheel is arranged in the middle of the slag raking opening, and a wind blocking component is arranged around the slag raking opening.
[0007] Further optionally, the sliding base is arranged as a frame-shaped structure matching the shape of the retaining wall, and a plurality of longitudinal rollers and supporting rollers are respectively supported on both sides and the top of the frame-shaped structure.
[0008] Further optionally, locking screws are arranged on the outer side of the sliding base.
[0009] Further optionally, the wind blocking component includes an air duct arranged along the edge of the slag raking opening, and a plurality of air holes inclined towards the center of the slag raking opening are formed on the air duct.
[0010] Further optionally, a layer of heat insulation cotton is arranged on the inner side of the blocking plate.
[0011] Compared with the existing technology, the beneficial effects of the utility model are as follows: By arranging a blocking plate that can be moved and adjusted on the upper part of the retaining wall of the slag discharge pit, the blocking plate can better adapt to the position of the ladle, not only avoiding the splashing of molten steel during slag raking and hurting people, but also blocking the heat radiation of high-temperature ferrosilicon alloy, improving the operation environment of the staff. Through the air seal of the wind blocking component at the inner slag raking opening, it can avoid the direct radiation of the high temperature of the ladle along the slag raking opening and ensure the sealing of the blocking plate.

[0015] In the figure: slag pit 1, retaining wall 2, heat insulation component 3, sliding base 4, longitudinal roller 5, support roller 6, baffle 7, charging opening 8, guide wheel 9, locking screw 10, air duct 11, air hole 12. Specific embodiments
[0016] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:
[0017] As Figure 1 , 2 shown, a slag discharging pit for ferrosilicon alloy materials includes a slag pit 1 and a retaining wall 2 arranged above it. A sliding base 4 is slidably connected to the upper part of one side of the retaining wall 2. A baffle 7 is fixed on the sliding base 4. The baffle 7 is made of a metal partition board, and its frame and inner side are reinforced with angle steel to prevent it from deforming due to heat. A charging opening 8 is opened on the baffle 7. A rotating guide wheel 9 is arranged in the middle of the charging opening 8. The charging rod is supported by rolling through the guide wheel 9, making the charging more labor-saving. A wind baffle component is arranged around the charging opening 8.
[0018] As Figure 2 shown, the sliding base 4 is arranged as a frame-shaped structure matching the shape of the retaining wall 2. A plurality of longitudinal rollers 5 and support rollers 6 are respectively supported on both sides and the top of the frame-shaped structure. The longitudinal rollers 5 on both sides are in contact with the side part of the retaining wall 2 to prevent the sliding base 4 from moving horizontally, while the support rollers 6 on the top play a supporting role to facilitate movement.
[0019] As Figure 3 shown, a locking screw 10 is arranged on the outer side of the sliding base 4, and the locking screw 10 can prevent the sliding base 4 from loosening.
[0020] As Figure 2 shown, the wind baffle component includes an air duct 11 arranged along the edge of the charging opening 8. A plurality of air holes 12 inclined towards the center of the charging opening 8 are opened on the air duct 11. Air with a certain pressure blown out from the plurality of air holes 12 can form a heat insulation air curtain to prevent heat radiation from passing through the charging opening 8.
[0021] A layer of heat insulation cotton is arranged on the inner side of the baffle 7, and the heat insulation cotton can improve the heat insulation effect of the baffle 7.
[0022] The implementation principle of a slag discharge pit for ferrosilicon alloy material in an embodiment of this application is as follows:
[0023] When skimming the surface slag in the ladle, the operator is outside the heat insulation component 3 and inserts the slag skimming rod into the skimming port 8 and supports it on the guide wheel 9, and repeatedly moves along the guide wheel 9 to use the front end of the slag skimming rod to skim the slag on the surface of the ladle into the slag pit 1, realizing the skimming of the slag.
[0024] During the whole process, the baffle plate 7 of the heat insulation component 3 plays a blocking role, which not only avoids the splashing of molten steel and hurting people during skimming, but also can block the heat radiation of high-temperature ferrosilicon alloy, improving the operation environment of the staff. Moreover, when the heat insulation component 3 is not directly facing the ladle and the operator cannot skim the slag better, the locking screw 10 can be loosened, and the sliding base 4 at the lower part of the baffle plate 7 can be moved. The sliding base 4 moves on the retaining wall 2 through the longitudinal rollers 5 and the supporting rollers 6, so as to adjust the position of the baffle plate 7 to make the skimming port 8 directly face the ladle, facilitating the operator to skim the slag more conveniently and efficiently.
[0025] At the same time, during the whole skimming process, the control valve of the air pipe 11 connected to the external air supply pipe (hose) can be opened to supply air into the air pipe 11 and blow directly to the center of the skimming port 8 through multiple air holes 12. In this way, the high-temperature radiation of the ladle can be avoided from directly irradiating along the skimming port 8, ensuring the sealing of the baffle plate 7.
[0026] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
