Description
Technical field
This utility model belongs to metallurgy industry steelmaking technical field, relates to a kind of for steel mill ladle argon bottom-blowing
From the facility being dynamically connected, particularly to a kind of gas coupling device.
Background technology
At present, domestic metallurgy industry iron and steel enterprise, use Argon guider for steel mill molten steel in the prior art
The automatic interconnection function of tank bottoms blowing argon gas, changes traditional-handwork and connects the most dangerous but also time-consuming situation.When ladle falls slowly
Seat is to while on ladle car, and argon-blowing device can engage with guider at leisure along the guide section of guider, until
Ladle realizes argon-blowing device after sitting on ladle car completely and engages completely with guider, reaches duty.At this
Period, argon-blowing device can produce low-angle swing and compression displacement.After ladle hangs ladle car, argon-blowing device leans on bullet
Spring resilience and ball ring realize automatically setting back putting.Guider is formed a fixed connection with ladle by the method for welding.
Argon-blowing device undersetting is pre-welded on ladle car body, then is fixed by argon-blowing device by bolt.Argon-blowing device is flexible
Structure, is made up of mobile jib, upper cover, spring, base, ball ring, locking nut and protective jacket.During work, spring entirety can produce
The swing of certain angle, also has a certain amount of being compressed axially.Lower spring end is enclosed within base and makes its upper end can be with mobile jib
Swing and swing, to compensate the site error of the guider horizontal direction that ladle deformation brings；Spring is axially compressed, and one
Being the site error that can compensate the guider vertical direction that ladle deformation brings, two tie when being and can meet gas coupling
The needs that conjunction face place seals.Being connected with base by ball ring by locking nut, one is to play spring pre-tightening effect；Two are to ensure that
Can reliable return when argon-blowing device does not works；Three is when guider just contacts with argon-blowing device, it is allowed to argon-blowing device
Produce and slightly swing.Protective jacket is asbestos friction material, prevents the foreign bodies such as high-temperature steel slag from entering stuck for spring inside argon-blowing device, from
And disablement.
Argon guider work under bad environment, the slag easily being fallen by top or sputtering smashes, burns out or buries.
Although existing argon-blowing device has protective jacket to protect, but protective capacities is limited, often damages and makes spring be exposed to severe ring
Border cannot be worked by slag is stuck, or quickly followed the string cannot work by reasons such as high-temperature bakings.Spring by compression same
Time also acted on by tilting moment, reduce service life.Especially when by shock loading, more exacerbate service life short
Situation, spring steel wire phenomenon of rupture even occurs.
Argon guider is divided into single line type and two-wire type.So-called two-wire type, is exactly to guide dress in single set Argon in fact
Putting when can not meet Large Steel water pot Bottom Blowing supply, the modes using two set Argon guiders in parallel meet ladle bottom blowing
Gas supply demand, investment cost increases nearly 1 times.
For above-mentioned reasons, both caused production maintenance inconvenience, operation troubles rate is high and the life-span is shorter, causes again two-wire type
Investment is close to the defects such as double.
