Description
Technical Field
The utility model relates to a ladle is with drainage sand instrument of adding sand belongs to ferrous metallurgy technical field.
Background
At present, the steel-making method adopted by the mainstream batch steel making in China and abroad is an electric furnace and a converter steel-making method, and no matter which scheme is adopted, molten steel must be transferred into a steel ladle (commonly called as a steel ladle) from the converter or the electric furnace, or refined and then continuously cast, or directly blown with argon and then continuously cast. During pouring, the instant drainage sand opened by the steel ladle sliding plate needs to flow out of the steel ladle along the water gap under the action of the static pressure of the molten steel, the molten steel flows out along the same way, namely the steel ladle is self-opened, otherwise, the instant drainage sand opened by the sliding plate cannot flow out along the water gap under the action of the static pressure of the molten steel, the molten steel cannot flow out, and the drainage sand needs to be boiled by introducing pure oxygen through the oxygen blowing pipe so that the molten steel can flow out along the water gap to enter the tundish, so that the pouring process is completed.
During the process of adding sand into the ladle, the funnel pipe is aligned with a ladle nozzle, and drainage sand can be scattered around the ladle nozzle; in the process of lifting the funnel, the drainage sand can be scattered along with the shaking of the funnel in the ascending process of the funnel, so that the drainage sand is scattered at the bottom of the bale. Therefore, accurate positioning and quantitative addition of the drainage sand cannot be realized, so that the probability of the ladle being opened automatically is increased; meanwhile, drainage sand is also consumed greatly.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a ladle is with drainage sand adds sand instrument is provided to above-mentioned prior art, can be quick, accurate add the drainage sand to the ladle, improve the ladle from the rate of opening, reduce the consumption of drainage sand.
The utility model provides a technical scheme that above-mentioned problem adopted does: a ladle used drainage sand sanding tool comprises a funnel and a sleeve, wherein a discharge port of the funnel is connected with a funnel pipe, the sleeve is arranged below the funnel, the funnel pipe is partially arranged in the sleeve, the funnel is connected with the sleeve through a flexible cable, a bottomless forming box is arranged at the bottom of the sleeve, and the bottomless forming box is communicated with the funnel pipe; the funnel is characterized in that a fixed pulley block is arranged above the funnel, a steel wire rope is arranged on the fixed pulley block, one end of the steel wire rope is connected with the funnel, and a balance weight is arranged at the other end of the steel wire rope.
The length of the sleeve is greater than that of the funnel pipe.
The bottomless forming box is square, and the size of the bottomless forming box is matched with the size of the nozzle pocket brick.
The weight of the counterweight is greater than the sum of the weights of the funnel and the sleeve.
Compared with the prior art, the utility model has the advantages of: the utility model provides a ladle is with drainage sand sanding tool, the funnel pipe is deepened the ladle mouth of a river, directly fills the ladle mouth of a river with the drainage sand, and the bottomless shaping box that the sleeve pipe bottom set up is direct contacts with the ladle bottom for in the drainage sand fills bottomless shaping box and sleeve pipe, make the drainage sand no longer disperse but gather the shape, avoided the drainage sand to scatter around the mouth of a river. The ladle filler sand filling device is convenient and fast to operate, can quickly and accurately fill the ladle nozzle with the filler sand, improves the self-opening rate of the ladle, and reduces the consumption of the filler sand.
Drawings
FIG. 1 is a schematic view of a ladle-used sand-filling tool for stuffing sand;
in the figure, a funnel 1, a flexible cable 2, a funnel tube 3, a fixed pulley block 4, a counterweight 5, a sleeve 6, a bottomless forming box 7 and a steel wire rope 8 are arranged.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in figure 1, the ladle used stuffing sand adding tool in the embodiment is arranged on a converter or electric furnace tapping platform. Including funnel 1 and sleeve pipe 6, 1 discharge gate of funnel is connected with funnel pipe 3, and 1 below of funnel is equipped with sleeve pipe 6, and 3 parts of funnel pipe are located in the sleeve pipe, and funnel 1 is connected through flexible cable 2 with 6 tops of sleeve pipe, and 6 bottoms of sleeve pipe set up bottomless shaping box 7, and bottomless shaping box 7 is square structure, and the size phase-match of brick at the bottom of the size and the mouth of a river. The bottomless forming box 7 is communicated with the funnel pipe 3, so that the drainage sand in the funnel 1 flows into the bottomless forming box 7 through the funnel pipe 3. The fixed pulley group 4 is arranged above the funnel 1, the fixed pulley group 4 is fixed on the steel tapping platform, the fixed pulley group 4 comprises two fixed pulleys, the two fixed pulleys are arranged in parallel, a steel wire rope 8 is arranged on the fixed pulleys, one end of the steel wire rope 8 is connected with the funnel 1, the other end of the steel wire rope 8 is provided with a balance weight 5, and the weight of the balance weight 5 is greater than the sum of the weights of the funnel 1 and the sleeve 6. When the balance weight 5 is lifted or descended, the fixed pulley block 4 and the steel wire rope 8 drive the funnel 1, the funnel pipe 3, the sleeve 6 and the bottomless forming box 7 to be close to or far away from a ladle nozzle.
The length of the sleeve 6 is greater than the length of the funnel 3.
During the sanding, the ladle is opened to the platform below, control counter weight 5, and funnel 1 downstream drives sleeve pipe 6 and sees through the hole on the platform and deepens into the ladle for bottomless shaping box 7 contacts with package end nozzle brick cup, sleeve pipe 6 is motionless, because be flexible cable 2 between funnel 1 and the sleeve pipe 6 and be connected, when counter weight 5 is still promoting, funnel pipe 3 continues the downstream, descends to in the ladle nozzle promptly. And pouring the drainage sand into the funnel 1, wherein the drainage sand flows to the ladle nozzle through the funnel pipe 3 until the ladle nozzle is filled. At the moment, the counterweight 5 is controlled, the funnel 1 moves upwards, and the sleeve 6 is fixed due to the connection of the flexible cable 2 between the funnel 1 and the sleeve 6, so that the drainage sand forms a certain shape in the bottomless forming box 7 and the sleeve 6. And finally, controlling the balancing weight to completely lift the funnel, the funnel pipe and the sleeve to finish the sand adding operation.
The funnel pipe in this application gos deep into the ladle mouth of a river, directly fills the ladle mouth of a river with the drainage sand, and the no end shaping box that the sleeve pipe bottom set up is direct contacts with the package end for in the drainage sand fills no end shaping box and sleeve pipe, make the drainage sand no longer disperse but gather the shape, avoided the drainage sand to scatter around the mouth of a river. The ladle filler sand filling device is convenient and fast to operate, can quickly and accurately fill the ladle nozzle with the filler sand, improves the self-opening rate of the ladle, and reduces the consumption of the filler sand.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
