Abstract

Provided is a U-shaped beam structure tundish. The U-shaped beam structure tundish comprises a tundish body, support plates and lifting trunnions, wherein the lifting trunnions are arranged on two sides of the middle of the tundish body, and the support plates are fixed at two ends of the tundish body. The tundish body comprises an inner contour plate, fixing collars, reinforced ribs, a base plate and lateral plates. The lateral plates are arranged at two ends of the inner contour plate, the two sides and the bottom of the inner contour plate are surrounded by the fixing collars, and the reinforced ribs are disposed between the fixing collars and the inner contour plate. The inner contour plate, the fixing collars, the reinforced ribs, the base plate and the lateral plates are in welded connection. The inner contour plate and the fixing collars are U-shaped, and the base plate is connected with the bottoms of the fixing collars. The U-shaped beam structure tundish has the advantages of being high in strength, light in weight, and capable of saving investment costs of corollary equipment.

Description

U type girder construction pans

Technical field

The utility model relates to the pans of metallurgical continuous casting equipment, particularly relates to U type girder construction pans.

Background technology

In the iron and steel metallurgical industry, on the continuous casting steel machine production line, molten steel enters into a cambic intermediate receptacle from ladle, and then flows into crystallizer, and this intermediate receptacle is referred to as pans.Pans have the effect of several aspects: 1, stabilized steel stream, reduce of impact and the stirring of steel stream to crystallizer, and stablize pouring operation; 2, even molten steel temperature and composition; 3, make the deoxidation product separate come-up with non-metallic inclusion; 4, count distribution steel stream on the conticaster in multithread.

The pans of billet caster are generally rectangle; Pans for the less casting machine of stream spacing; In order to make ladle steel stream decanting point to each flowing water mouth suitable distance arranged and reduce area of dissipation as far as possible, special-shaped pans have been developed out, like trapezoidal pans and tee T pans.Consider hanging, deposit, clear up and building by laying bricks or stones of pans, the profile of pans should be tried one's best simply.

For the little square billet of big fluxion (fluxion is more than 8 streams reach); Traditional approach is generally according to two design for continuous casting machine, or two jar pieces together the cast of two together mouths of a river, like this; All want corresponding increasing configuration with the supporting two intermediate tundish carriages of pans, bale panoramic tables etc., increased cost of investment.Come in the recent period, the domestic 8 stream monoblock type pans that also occurred design, and consider pans body intensity, have increased pans fixing collar and reinforcing rib design, cause this body weight of pans sharply to increase, and have also increased the investment of its hanging device (large-tonnage overhead traveling crane).

Summary of the invention

The purpose of the utility model provides a kind of U type girder construction pans, these U type girder construction pans, and intensity is high, and is in light weight, can save the cost of investment with its corollary equipment.

In order to achieve the above object, the U type girder construction pans of the utility model comprise pans body, gripper shoe and play shackle shaft; Play shackle shaft and be fixed on both sides, pans body middle part, gripper shoe is fixed on pans body two ends, and the pans body is made up of interior profile plate, fixing collar, reinforcement, base plate and side plate; Side plate is at interior profile plate two ends; Profile plate both sides and bottom in fixing collar is enclosed in, reinforcement are between fixing collar and interior profile plate, and the connection between interior profile plate, fixing collar, reinforcement, base plate and the side plate is adopted and is welded to connect; It is characterized in that: interior profile plate and fixing collar are the U type, and base plate is connected with the fixing collar bottom.

Because interior profile plate and fixing collar are the U type, the reinforcement between fixing collar and interior profile plate also is the U type, contrasts traditional pans structure; Reinforcement parcel scope is bigger, and after direct and base plate was integrally welded, fixing collar and interior profile plate formed dual support; Increase the rigidity and the intensity of pans, can prevent the pans excessive deformation that is heated, helped guaranteeing mouth of a river accuracy of alignment; In the same bearer ability; And guarantee under the pans body strength condition, more in light weight than traditional monoblock type pans, the cost of investment of saving itself and corollary equipment (large-tonnage overhead traveling crane).

Described U type girder construction pans is characterized in that: gripper shoe adopts box-structure to be welded, and can alleviate the stress concentration phenomenon of gripper shoe bottom and intermediate tundish carriage contact position.

Described pans body and gripper shoe are general carbon steel material, and interior profile plate and fixing collar bottom have a plurality of steel flow outlets, and playing shackle shaft is that the suspension strut point is used in the pans lifting.

The U type girder construction pans of the utility model, intensity is high, and is in light weight, can save the cost of investment with its corollary equipment.

Fig. 3 is a B-B cutaway view among Fig. 1.

Fig. 4 is a C-C cutaway view among Fig. 1.

The specific embodiment

The explanation of Fig. 1 mark: pans body 1, gripper shoe 2 plays shackle shaft 3.

The explanation of Fig. 3 mark: side plate 4, interior profile plate 5, reinforcement 6, fixing collar 7, base plate 8.

Referring to Fig. 1, the embodiment of the utility model U type girder construction pans belongs to a kind of of tee T pans, comprises pans body 1, gripper shoe 2 and plays shackle shaft 3, and play shackle shaft 3 and be fixed on pans body 1 both sides, gripper shoe 2 is fixed on gripper shoe 2 two ends.

Referring to Fig. 3; Pans body 1 is made up of interior profile plate 5, fixing collar 7, reinforcement 6, base plate 8 and side plate 4, and side plate 4 is at interior profile plate 5 two ends, profile plate 5 both sides and bottom in fixing collar 7 is enclosed in; Reinforcement 6 is between fixing collar 7 and interior profile plate 5; Connection between interior profile plate 5, fixing collar 7, reinforcement 6, base plate 8 and the side plate 4 is adopted and is welded to connect, and interior profile plate 5 is the U type with fixing collar 7, and base plate 8 is connected with fixing collar 7 bottoms.

Because interior profile plate 5 is the U type with fixing collar 7, the reinforcement 6 between fixing collar 7 and interior profile plate 5 also is the U type, contrasts traditional pans structure; Reinforcement 6 parcel scopes are bigger, directly with base plate 8 integrally welded after, fixing collar 7 and interior profile plate 5 formation dual support; Increase the rigidity and the intensity of pans, can prevent the pans excessive deformation that is heated, helped guaranteeing mouth of a river accuracy of alignment; In the same bearer ability; And guarantee under pans body 1 strength condition, more in light weight than traditional monoblock type pans, the cost of investment of saving itself and corollary equipment (large-tonnage overhead traveling crane).

Among the embodiment; Gripper shoe 2 adopts box-structure to be welded; Can alleviate the stress concentration phenomenon of gripper shoe 2 bottoms and intermediate tundish carriage contact position, pans body 1 is general carbon steel material with gripper shoe 2, and interior profile plate 5 has a plurality of steel flow outlets with fixing collar 7 bottoms.

The U type girder construction pans of the utility model, intensity is high, and is in light weight, can save the cost of investment with its corollary equipment.Its promotion and application, to improving the job stability of pans, practicing thrift cost of investment has positive meaning.
