Abstract
The utility model belongs to the improvement of steel mill continuous casting weir and dam in tundish structure, especially a package blows argon barricade in middle of modified, including middle package, setting up the barricade in the middle of the middle package, pre -buriedly in the barricade of centre package blow the argon pipeline, blow argon pipeline one end and middle package refractory material layer's the external pipeline intercommunication of supplying gas, the pre -buried equipartition that blows about the argon pipeline on the both sides respectively in the barricade is being installed and is being blown the argon branch pipe. The utility model is simple and reasonable in structure, use swiftly, with low costs, can guarantee has the longer come -up time in the package in the middle of the inclusion in the molten steel, can make molten steel more even in the package of centre, helps improving the continuous casting billet quality.
Description
Technical field
The utility model belongs to the improvement of steel plant continuous casting weir and dam in tundish structure, the tundish Argon barricade of particularly a kind of improvement.
Background technology
How steel plant continuous casting tundish, as the container of the liquid molten steel of last splendid attire of steel making working procedure, play its metallurgical function to greatest extent, is the problem that continuous casting worker is concerned about always.In tundish, arrange barricade is one of the most frequently used means, its major function one be gear toward the liquid slag on liquid steel level in the slag and tundish of large bag, two is adjust Tundish Flow Field.The barricade of current use is old-fashioned weir structure, it only can play the effect of pushing off the slag, but the corrective action in centering bag flow field is very little, the metallurgical function of tundish cannot be given full play to, it mainly there is following defect: though can change the molten steel flow field in tundish, but the average steel Flow Velocity in tundish is still very fast, cannot increase the time of staying of molten steel in tundish preferably.Due to molten steel barricade and gear dam surface velocity very fast, easily cause the melting loss of resistance to material on barricade and gear dam, especially the melting loss of barricade is serious, and when playing the effect of barricade after its melting loss, its resistance to material fuses in steel and increases being mingled with in molten steel.
The subject matter that tradition weir and dam in tundish exists is as follows:
1, the average steel Flow Velocity in tundish is still very fast, cannot increase the time of staying of molten steel in tundish preferably.
2, molten steel barricade and gear dam surface velocity very fast, easily cause the melting loss of resistance to material on barricade and gear dam, reduce tundish service life.
3, cannot play the effect of barricade after barricade melting loss, its resistance to material fuses in steel and increases being mingled with in molten steel, causes adverse effect to continuous casting billet quality.
Utility model content
The purpose of this utility model is the tundish Argon barricade providing a kind of improvement, it is simple and reasonable for structure, use quick, cost is low, can ensure there is longer floating interval of floating dock in the field trash tundish in molten steel, more even in tundish of molten steel can be made, contribute to improving continuous casting billet quality.
The purpose of this utility model is achieved in that a kind of tundish Argon barricade of improvement, comprise tundish, in the middle of tundish, barricade is set, pre-buried Argon pipeline in the barricade of tundish, Argon pipeline one end is communicated with the external air duct of tundish refractory masses, is embedded in uniformly respectively on the upper and lower both sides of Argon pipeline in barricade to be installed with Argon arm.
It is as follows that the utility model mainly improves content:
1, at the inner pre-buried Argon pipeline of barricade, the barricade material of parcel pipeline adopts gas permeable material, and molten steel, at now the tundish process blowing argon gas, impels the field trash in molten steel constantly to float, and ensures there is longer floating interval of floating dock in the field trash tundish in molten steel.
2, adopt the utility model can reduce the dead space volume point rate of molten steel in tundish greatly, utilize the volume of tundish to greatest extent, make more even in tundish of molten steel.
Main improvement effect:
1, the continuous Argon of MOLTEN STEEL FLOW process in tundish, impels the field trash in molten steel constantly to float, and ensures there is longer floating interval of floating dock in the field trash tundish in molten steel.
2, the volume of tundish can be utilized after improving to greatest extent, make more even in tundish of molten steel, contribute to improving continuous casting billet quality.
3, barrier wall structure, volume, weight, installation etc. are the same with original installation and application, easy to use, cost is lower.
The utility model is simple and reasonable for structure, and use quick, cost is low, ensure that in the field trash tundish in molten steel have longer floating interval of floating dock, makes more even in tundish of molten steel, improves continuous casting billet quality.
Accompanying drawing explanation
Be further described the utility model below in conjunction with accompanying drawing, Fig. 1 is perspective view of the present utility model, and Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Detailed description of the invention
A kind of tundish Argon barricade of improvement, as shown in Figure 1 and Figure 2, comprise tundish 1, in the middle of tundish 1, barricade 2 is set, pre-buried Argon pipeline 3 in the barricade 2 of tundish, Argon pipeline 3 one end is communicated with the external air duct of tundish refractory masses, is embedded in uniformly respectively on Argon pipeline about 3 both sides in barricade 2 to be installed with Argon arm 4.The quantity of side Argon arm 4 is 6-8.The refractory material material of parcel Argon arm 4 is made up of gas permeable material.
Claims (3)
1. the tundish Argon barricade improved, comprise tundish (1), in the middle of tundish (1), barricade (2) is set, it is characterized in that: pre-buried Argon pipeline (3) in the barricade (2) of tundish, Argon pipeline (3) one end is communicated with the external air duct of tundish refractory masses, is embedded in that Argon pipeline (3) in barricade (2) is uniform respectively on both sides is up and down installed with Argon arm (4).
2. the tundish Argon barricade of a kind of improvement according to claim 1, is characterized in that: the quantity of side Argon arm (4) is 6-8.
3. the tundish Argon barricade of a kind of improvement according to claim 1, is characterized in that: the refractory material material of parcel Argon arm (4) is made up of gas permeable material.
