Abstract
The invention discloses a production device for continuous casting of vertical tube blanks, which comprises a steel ladle, wherein the steel ladle is communicated with a middle ladle, the middle ladle is communicated with a crystallizer, a vibrator is connected outside the crystallizer, a two cooling section assembly is perpendicularly arranged at the lower part of the crystallizer, a dummy bar passes through the roller gap of the two cooling section assembly, the head part of the dummy bar is inserted in the crystallizer, and a support roller device clamps the bottom part of the dummy bar. The molten steel in the steel ladle is poured into the middle ladle and then poured into the crystallizer; the molten steel is cooled in the crystallizer to form a hollow tube blank with a liquid core; when the molten steel in the crystallizer reaches a certain level, the vibrator is started and the support roller device is started, the support roller device pulls the dummy bar to move down, and the dummy bar drives the hollow tube blank to move down and move out; the hollow tube blank is cut by a cutting machine according to needs, and tube blanks are discharged through an oblique discharge system. The production device achieves the purpose of continuous casting of hollow tube blanks, reduces the production cost, saves resources and increases the yield, and fills in the blank of the technology at home and abroad.
Description
Technical field
The present invention relates to technical field of metallurgical equipment, particularly a kind of process units of vertical pipe continuous casting.
Background technology
At present, also there is not to produce continuously the conticaster of hollow bloom both at home and abroad.The mode of production of tradition pipe has die casting solid and hollow bloom, continuous casting square billet and the solid pipe of circle base, centrifugally cast pipe and pipe.Need solid heating of pipe blank perforation with solid pipe rolling seamless steel pipe.Die casting hollow bloom and its mode of production of centrifugal casting pipe all can not be produced hollow bloom continuously, and its production cost is high, wastes energy, and yields poorly.
Summary of the invention
In order to overcome the defective of prior art, the object of the present invention is to provide a kind of process units of vertical pipe continuous casting, can produce hollow bloom continuously, reduce production costs, economize on resources, improve output.
In order to achieve the above object, the technical solution of the present invention's employing is:
A kind of process units of vertical pipe continuous casting comprises steel ladle 1, and steel ladle 1 is connected with tundish 3 through long nozzle 2; Tundish 3 is connected with crystallizer 5 through two submersed nozzles 4; Crystallizer 5 be externally connected to vibrating device 6, the lower vertical of crystallizer 5 is provided with secondary cooling zone group 8, is installed with dummy bar 7 in the roll gap of secondary cooling zone group 8; The head of dummy bar 7 inserts in the crystallizer 5, and support roller device 9 clamps the bottom of dummy bar 7.
Described crystallizer 5 is tube type molds of cored bar.
Described tundish 3 is provided with molten steel induction heating apparatus 12.
Vertical hollow bloom conticaster of the present invention, problem that can not the continuous pouring hollow bloom before having solved has reduced production cost, has economized on resources, improved output, has filled up the blank of domestic and international this technology.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of the tundish 3 of band molten steel induction heating apparatus.
The practical implementation method
Below in conjunction with accompanying drawing the present invention is made further detailed description.
With reference to Fig. 1; A kind of process units of vertical pipe continuous casting comprises steel ladle 1, and steel ladle 1 is connected with tundish 3 through long nozzle 2; Submersed nozzle inserts in the crystallizer; The submersed nozzle tapping hole is apart from crystallizer 200mm～250mm suitable for reading, and tundish 3 is connected with crystallizer 5 through two submersed nozzles 4, and two submersed nozzles 4 make molten steel evenly smooth in crystallizer.Crystallizer 5 be externally connected to vibrating device 6; Be vertically installed with secondary cooling zone group 8 below the crystallizer 5, be installed with dummy bar 7 in the roll gap of secondary cooling zone group 8, the head of dummy bar 7 inserts in the crystallizer 5; Support roller device 9 clamps the bottom of dummy bar 7, holder drawing spindle blade 7 and the strand that solidifies.
Described crystallizer 5 is tube type molds of cored bar, can produce hollow bloom.
With reference to Fig. 2, described tundish 3 is provided with molten steel induction heating apparatus 12.
Operation principle of the present invention is: the steel ladle 1 that holds molten steel is through long nozzle 2; Molten steel is injected in the tundish 3; Tundish 3 has heating function with molten steel temperature drop and purify hot metal in the compensation casting, molten steel stops about 10～15 minutes in tundish after; Be injected in the crystallizer 5 through submersed nozzle 4, molten steel cools off to form in crystallizer and has liquid core hollow bloom; After the molten steel in the crystallizer reach a certain height, vibrating device 6 started, and beginning is being with crystallizer 5 to vibrate together up and down according to certain curve; Meanwhile, support roller device 9 starts, and support roller device 9 is pushed down dummy bar 7 and moved downward, and dummy bar 7 is being with hollow bloom to move downward; After hollow bloom is drawn out crystallizer 5, get into secondary cooling zone 8,8 pairs of hollow blooms of secondary cooling zone play a supportive role and the hollow bloom of using crystallizer band liquid core solidifies fully; When hollow bloom arrived cutting machine 10, cutting machine 10 began to cut hollow bloom, and after cutting was accomplished, hollow bloom and dummy bar 7 broke away from, and dummy bar 7 transports through oblique knockout system 11; Cutting hollow bloom and transporting in the process of dummy bar 7, support roller device 9 is pushed down the downward throwing of hollow bloom always, and after reaching scale, cutting machine 10 cuts hollow bloom once more, and after cutting was accomplished, hollow bloom transported through oblique knockout system; The process of repeat throwing later on, cutting, transport.
Characteristics of the present invention are:
1. adopt vertical casting machine to produce hollow bloom, energy savings continuously.
2. tundish 3 is established the molten steel induction heating apparatus and is had heating function with molten steel temperature drop and purify hot metal in the compensation casting, and two cover submersed nozzles 4 symmetric arrangement crystallizer 5 in makes molten steel smooth even in crystallizer.
3. it is hollow to adopt the tube type mold 5 of cored bar that pipe is formed in crystallizer 5.Crystallizer 5 water flowings cooling, and the water yield is adjustable.Plug top connecting plate is connected with crystallizer by bolt with crystallizer 5 top boards and on vibrating device 6, moves up and down; Can change plug according to required aperture; The inner water flowing cooling of plug; Also be provided with the cold gas pipeline of cooling pipe endoporus in the plug, the plug skin is provided with self-lubricating material and prevents pipe inner casing and plug bonding.
4. adopt hydraulic vibration device 6 online adjustable amplitudes, frequency and angle of deviation, select to be applicable to the model of vibration and the vibration parameters of casting pipe.
5. secondary cooling zone adopts carbonated drink atomizing cooling, dynamically control.
6. crystallizer 5 is equipped with curdled appearance and the solidified structure that electromagnetic agitation is improved pipe with secondary cooling zone 8.
