Abstract
The utility model discloses a connection part for rapid tundish change, comprising a first rectangular frame, a second rectangular frame and an impact steel plate. The first rectangular frame is arranged on the top; the second rectangular frame is arranged below the first rectangular frame; the impact steel plate is arranged below the second rectangular frame; and the first rectangular frame and the second rectangular frame as well as the second rectangular frame and the impact steel plate are connected by a plurality of steel bars. Due to the adoption of the connection part for rapid tundish change, the rapid tundish change for continuous casting can be realized, the continuous cast heats can be increased, and the casting machine operation rate can be improved.
Description
Technical field
The utility model relates to the metallurgical continuous casting technical field, more specifically, is that a kind of fast quick change bag that is used for bloom continuous casting is used connector.
Background technology
In metallurgical continuous casting technology, the quick replacing Tundish Technology of bloom is that continuous casting realizes connecting the key technology of watering; Its main advantage is: improve to connect and water the stove number, improve caster work rate, production capacity, reduce downtime; Improve the strand recovery rate, the aspect such as is watered at by the company that realizes different steel grades.Wherein, changing bag is the critical component of realizing changing fast Tundish Technology with connector, and its advantage is: 1) the front and back steel grade is carried out physical segmentation, reduce mixed steel and scrap, reduce cost; 2) connector has increased the bonding strength of molten steel, has reduced and has opened the probability that waters bleed-out after changing tundish.
At present, because the difference of aspects such as domestic and international associated casting machine steel grade that equipment is produced and technology, applied fast quick change bag program and equipment are also varied, basically all relate to connector but change Tundish Technology fast.Each enterprise use and present most patent in the version of mentioned connector also of all kinds; The employing steel plate structure that has is made; The structure that the employing that has is complicated, cost of manufacture is higher, uses heavy; Even can cause scuffing to copper plate of crystallizer, its final purpose is exactly to open the probability that waters bleed-out after reducing the replacing tundish.
Therefore, need a kind of novel fast quick change bag use connector, realize that bloom changes at the tundish that continuous casting connects in the pouring technique fast.
The utility model content
The purpose of the utility model is to overcome the deficiency that exists in the above-mentioned fast quick change bag equipment, thereby provides a kind of novel fast quick change bag to use connector.
The fast quick change bag of the utility model is used connector; Comprise first rectangular frame that is positioned at the top, be positioned at second rectangular frame of said first rectangular frame below and the impact steel plate that is positioned at said second rectangular frame below, be connected through many steel bars between wherein said first rectangular frame and second rectangular frame and between said second rectangular frame and the said impact steel plate.
Preferably, the area of said first rectangular frame is greater than the area of said second rectangular frame.
Preferably, said first rectangular frame is provided with two clamping steel bars parallel to each other.
Utilize the fast quick change bag of the utility model to use connector, can realize changing fast tundish and even water operation, improve to connect and waters stove number and caster work rate, reduce downtime, and can further reduce the learies of handing-over base, the comprehensive recovery rate of raising continuous casting.
Description of drawings
Fig. 1 is the schematic perspective view of the fast quick change bag of the utility model with connector;
Fig. 2 is reduced to the vertical view of lines with connector for the fast quick change bag of the utility model among Fig. 1;
Fig. 3 is the schematic flow sheet that utilizes the fast quick change bag of the utility model to carry out the quick replacing tundish operation of large square bland continuous-casting machine with connector.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, the fast quick change bag of the utility model composition structure and the operation principle with connector is elaborated.
Like Fig. 1, shown in 2, the fast quick change bag of the utility model is used connector, comprises first rectangular frame 10 that is positioned at the top, is positioned at second rectangular frame 20 of first rectangular frame, 10 belows and the impact steel plate 30 that is positioned at second rectangular frame, 20 belows.First rectangular frame 10 and second rectangular frame 20 can be welded by many steel bars respectively, also can be integrally formed by a steel bar.More specifically, between first rectangular frame 10 and second rectangular frame 20 and second rectangular frame 20 be connected through many steel bars 40 with impacting between the steel plate 30.In the embodiment shown in the figure; First rectangular frame 10 is connected through 8 steel bars with each corresponding long limit of second rectangular frame 20; Broadside is connected through 6 steel bars 40, and the long limit of second rectangular frame 20 also is connected with impact steel plate 30 with 6 steel bars 40 through 8 respectively with broadside.After connecting first rectangular frame 10 and second and holding the steel bar of framework 20 and also can pass through bending machining, connect simultaneously and impact steel plate 30.Above connected mode is welding (shown in solder joint among Fig. 2 50).
On size design, the area of first rectangular frame 10 is greater than the area 20 of second rectangular frame.And the long limit 11 of first rectangular frame 10 and broadside 12 outlines are less than the length of crystallizer section and wide, so that can not damage copper plate of crystallizer behind the expanded by heating.
In addition, preferably, first rectangular frame 10 is provided with two clamping steel bars parallel to each other 13,14.Clamping steel bar 13,14 can be welded on the pair of long edges or minor face of first rectangular frame 10, and clamping steel bar 13, the distance between 14 should be arranged for ease of submersed nozzle and insert, and is touched to avoid submersed nozzle.
Below in conjunction with Fig. 3, the flow process of the connector that utilizes the utility model being carried out the quick replacing tundish operation of large square bland continuous-casting machine describes.Particularly, in step S100, a last basket pouring finishes, and middle hired car drives away, and strand is located in crystallizer automatically.Then promptly, in step S200, the skull around the crystallization wall is chosen, and before strand liquid core solidifies, rapidly the connector of the utility model is assigned into wherein, guarantee simultaneously to assign and do not have, to avoid touching copper plate of crystallizer.In step S300, reaffirm that each flows interior connector and inserts in the strand, do not have, and affirmation crystallization periphery of inner wall does not have bits.After accomplishing above-mentioned steps, in step S400, another tundish is reached the cast position, unwrap greatly successively to water to open and water operation with each stream of tundish.In above operation, connector should insert rapidly, and guarantees not have no skull.
In sum, utilize the fast quick change bag of the utility model to use connector, can realize changing fast tundish and even water operation; Improve to connect and water stove number and caster work rate; Reduce downtime, and can further reduce the learies of handing-over base, improve the comprehensive recovery rate of continuous casting.The application of the connector of the utility model has also increased the molten steel bonding strength, has reduced to open and has watered the bleed-out probability.In addition, the connector of the utility model has also reduced to open and has watered raw-material consumption, for example consumption such as seal, V-block, spring.
