Abstract
The utility model discloses an improve ladle bottom masonry structure of molten steel yield relates to steel smelting technical field, including mouth of a river brick cup, buffering seam, the buffering seam is located mouth of a river brick cup periphery, still includes the stabilizer, and the stabilizer sets up adjacent mouth of a river brick cup side, is located between mouth of a river brick cup and the buffering seam. The higher flow stabilizing plate forms resistance to molten steel, effectively delays the time for forming vortex, can reduce 1-3 tons of molten steel remained in a ladle under the condition of not influencing the quality of the molten steel, and improves the yield of the molten steel.
Description
Technical Field
The utility model relates to a steel smelting technical field especially relates to a ladle bottom masonry structure who improves molten steel yield.
Background
During continuous casting of the ladle, molten steel in the molten steel tank flows out through the tap hole brick holes, as shown in figures 3 and 4, in the flowing process, the molten steel forms vortex, and steel slag on the surface of the molten steel is involved into the molten steel along with the vortex as the height of the molten steel in the molten steel tank is reduced. In order to avoid the steel slag from being involved in the molten steel, the molten steel is stopped pouring before the eddy current formed by the molten steel affects the steel slag on the surface of the molten steel in the ladle, so that 3 to 7 tons of molten steel are remained in the ladle, and particularly, the more the molten steel of a special steel grade is remained. This reduces the yield of molten steel and causes a great waste of energy.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above technical problem, overcome prior art's shortcoming, provide an improve ladle bottom masonry structure of molten steel yield, including mouth of a river brick cup, buffering seam, the buffering seam is located mouth of a river brick cup periphery, still includes the current stabilizer, and the current stabilizer sets up adjacent mouth of a river brick cup side, is located between mouth of a river brick cup and the buffering seam.
The utility model discloses the technical scheme who further injects is:
the ladle bottom masonry structure for improving the yield of the molten steel has the advantages that the thickness of the flow stabilizing plate is 50-300mm, and the width of the flow stabilizing plate is 200-400mm.
According to the ladle bottom masonry structure for improving the yield of molten steel, the height of the flow stabilizing plate is increased by 30-100mm according to actual conditions on the basis of the height of the nozzle brick.
The ladle bottom masonry structure for improving the yield of the molten steel is characterized in that the flow stabilizing plate is arranged on one side of the nozzle brick close to the ladle shell.
The utility model has the advantages that: the higher flow stabilizing plate forms resistance to molten steel, effectively delays the time for forming vortex, can reduce 1-3 tons of molten steel remained in a ladle under the condition of not influencing the quality of the molten steel, and improves the yield of the molten steel.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a cross-sectional view of the present invention;
FIGS. 3 and 4 are schematic diagrams of background art;
wherein: 1. a nozzle pocket brick; 2. buffering the seam; 3. a flow stabilizer.
Detailed Description
A nozzle pocket brick 1 is built at the bottom of a 60-ton molten steel tank, the length, width and height of the nozzle pocket brick are 360 multiplied by 400mm, the original construction mode is that a buffer seam 2 with 40-100mm is reserved around the nozzle pocket brick 1, and corundum self-flowing materials are poured into the buffer seam 2 until the nozzle pocket brick 1 is flush after other ladle bottoms are built. About 4 tons of molten steel is generally remained in a molten steel tank after continuous casting, the service life of a primary slag line of a ladle is 40 furnaces, 160 tons of molten steel are required to be poured in the period of maintenance in one ladle, and great waste is caused.
The ladle bottom masonry structure for improving the yield of molten steel provided by the embodiment has the structure shown in fig. 1-2, a flow stabilizing plate 3 with the length, width and height of 300 x 450mm is additionally arranged next to a nozzle block brick 1, the flow stabilizing plate 3 is arranged on one side of the nozzle block brick 1 close to a ladle shell, a buffering seam 2 with the width of 50mm is reserved around the nozzle block brick 1 and the flow stabilizing plate 3, and corundum castable is poured after masonry is completed. The material of the flow stabilizing plate 3 is corundum spinel material. By the design, on the premise of not influencing the quality of molten steel, only 2.5 tons of molten steel need to be retained in the molten steel tank on average, the waste of 60 tons of molten steel is reduced in the middle repair period of one steel ladle, and the yield of the molten steel is improved.
In addition to the above embodiments, the present invention may have other embodiments; all the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
