Abstract
The utility model discloses a kind of ladle anti-gas-leak air brick cores, inner core including having airflow channel, and the sheath of cladding innercore sidewall and bottom wall, the snorkel being connected with airflow channel is provided in the bottom of sheath, gap package has and the consistent outer sleeve of its shape on the lateral wall of sheath, the lower end of outer sleeve passes through several connecting columns being evenly distributed and is fixedly connected with sheath, and outer jacket is filled in the gap between sheath and outer sleeve.The utility model advantage is that structure is simple, processes and using easy.Increase outer sleeve on the outside of the sheath of original inner core; and outer jacket is filled in the gap between sheath and outer sleeve, it forms the second layer and protects structure, if fracture gas leak phenomenon occurs in inner core; second layer protection structure remains to protection air-flow indiffusion, guarantees that airflow channel is unimpeded；Effective protection porous core prevents porous core because fracture and gas leakage shift to an earlier date offline phenomenon, guarantees ladle safe operation, greatly increase company's benefit.
Description
Technical field
The utility model relates to Refractory For Steelmakings, more particularly, to a kind of ladle anti-gas-leak air brick core.
Background technique
Air brick is the functional product of ladle, and key effect is played in steel-making；Its main function is to steel
Blowing argon gas in wrapping, to reach the purpose of degassing, decarburization and removal oxide are mingled with, so that uniform stirring molten steel, guarantees molten steel
Refining reaches required standard.Due to air brick receive repeatedly thermal stress of the impact of molten steel, thermal shock, erosion and temperature etc. it is many because
Element, therefore it is easiest to the problems such as fracture, airflow channel blocking occurs, to cause gas blowby or become flat from breaking joint, cause ladle
It is improper offline, safety accident can be also caused when serious, causes immeasurable loss.
Summary of the invention
The utility model aim is to provide a kind of ladle anti-gas-leak air brick core of manufacture easy to process.
To achieve the above object, the utility model can take following technical proposals:
Ladle described in the utility model anti-gas-leak air brick core, the inner core including having airflow channel, and cladding
The sheath of the innercore sidewall and bottom wall is provided with the snorkel being connected with the airflow channel in the bottom of the sheath,
Gap package has on the lateral wall of the sheath passes through circumferentially with the consistent outer sleeve of its shape, the lower end of the outer sleeve
Uniformly distributed several connecting columns are fixedly connected with the sheath, and outer shield is filled in the gap between the sheath and the outer sleeve
Layer.
Spacing distance between the sheath and the outer sleeve is 20 ~ 40mm.
The utility model advantage is that structure is simple, processes and using easy.Increase on the outside of the sheath of original inner core outer
Sleeve, and outer jacket is filled in the gap between sheath and outer sleeve, it forms the second layer and protects structure, if inner core is broken
Gas leak phenomenon (fracture of general inner core is broken outward since internal airflow channel), second layer protection structure remains to protect
Air-flow indiffusion guarantees that airflow channel is unimpeded；By on probation, the access times of porous core are increased to 40 times by original 30 times,
Whole multi-purpose 10 times, and worked well every time using can guarantee, effective protection porous core prevents porous core because of fracture and gas leakage
Phenomenon offline in advance guarantees ladle safe operation, greatly increases company's benefit.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the top view of Fig. 1.
Specific embodiment
As shown in Figure 1, 2, ladle described in the utility model anti-gas-leak air brick core, including having airflow channel 1
Inner core 2, and the sheath 3 of cladding 2 side wall of inner core and bottom wall, the bottom of sheath 3 be provided be connected with airflow channel 1 it is logical
Tracheae 4 is blown (generally argon gas) into snorkel 4, and air-flow can be blown into ladle through airflow channel 1, to reach steelmaking process
The purpose of middle degassing, decarburization and removal oxide are mingled with；Gap package has consistent outer with its shape on the lateral wall of sheath 3
The material of sleeve 5, outer sleeve 5 is consistent with 3 material of sheath, is steel material, can effectively avoid that fracture occurs, prevent ladle from leaking
Gas；The lower end of outer sleeve 5 passes through several connecting columns 6 being evenly distributed and is fixedly connected with sheath 3, between sheath 3 and outer sleeve 5
Gap in be filled with outer jacket 7, spacing distance between sheath 3 and outer sleeve 5 is 20 ~ 40mm, i.e., outer jacket 7 with a thickness of
The material of 20 ~ 40mm, outer jacket 7 are consistent with 2 material of heart, are refractory brick, and such outer jacket 7 and outer sleeve 5 just form
The second layer protects structure.
When inner core 2 is heated for a long time fracture gas leak phenomenon occurs, since heart 2 is coated with the sheath 3 of steel,
Heart 2 can be generally broken outward since internal airflow channel 1, and the second layer is protected structure to remain to protection air-flow and do not expanded at this time
It dissipates, guarantees that airflow channel 1 is unimpeded.By on probation, the access times of ladle described in the utility model anti-gas-leak air brick core by
30 times originally are increased to 40 times, are only improved by simple structure, and access times can just improve 10 times fully, and can be guaranteed
What is used every time is functional, effective protection porous core, prevents porous core because fracture and gas leakage shift to an earlier date offline phenomenon, guarantees steel
Packet safe operation, greatly increases company's benefit.
