Description
Technical field
This utility model relates to tundish argon gas blowing device.
Background technology
Continuous casting technology has become as current metallurgy industry, particularly the main flow foundry engieering in smelting iron and steel enterprise, and the tundish in continuous casting technology is indispensability holds steel container, is also the critical container realizing the direct casting of many stoves.And built the tundish of refractory lining by laying bricks or stones before use of reaching the standard grade, it is necessary to through high-temperature baking, liner is carried out temperature raising process, then carry out watering steel operation.During watering steel operation, particularly the first stove watering molten steel driven by big bag in tundish, outside air and baking residual gas are trapped in tundish, liquid steel water in tundish is produced secondary oxidation, cause that in molten steel, oxide inclusions increases, have impact on the cleanliness factor of molten steel, contaminated molten steel is mingled with all kinds of oxidation product and enters steel billet, by the properties generation impact on steel billet, even result in the quality accident in steel following process use procedure.
By being blown into noble gas in tundish and dilute, the oxidizing gas such as the air of replacing in tundish, it is possible to effectively reduce and open the secondary oxidation of molten steel when watering.It is generally adopted conduit peschel at present and connects argon, by artificial hand-held insertion tundish, it is blown into argon in tundish, the method to gas instead in tundish not exclusively, argon time swap is longer, argon is in tundish flowing irregular, can not effective air-out, the tundish lining that the argon that tunger tube is blown into simultaneously directly impacts, Local cooling cooling is serious, adds and opens the molten steel temperature drop watering heat and open the probability watering failure.
Utility model content
The purpose of this utility model is in that to provide a kind of tundish argon gas blowing device, and tundish can be carried out Argon by it, and Argon is effective.
For achieving the above object, the technical solution of the utility model is a kind of tundish argon gas blowing device of design, including:
The gas transmission hard tube being connected with argon source of the gas,
By the connecting tube that movable soft tube connects with gas transmission hard tube,
Two ends connect the movable soft tube of gas transmission hard tube, connecting tube respectively,
By the argon distribution header that snap joint is connected with connecting tube,
For supporting the tundish cover of argon distribution header,
And respectively through with argon distribution header, for insert tundish and to tundish carry argon multiple argon arms；
Described gas transmission hard tube is provided with manual ball valve and pressure-regulating valve；
Each argon arm is vertical with argon distribution header, and each argon arm is positioned at argon distribution header the same side；
Described tundish cover is provided with and argon arm vertical through holes one to one；
Each argon arm inserts corresponding through hole and stretches into tundish bottom.
Preferably, described snap joint includes: is located at the female joint in connecting tube, and is located at the male joint in argon distribution header.
Preferably, described argon arm is uniform in argon distribution header.
Advantage of the present utility model and having the beneficial effects that: providing a kind of tundish argon gas blowing device, tundish can be carried out Argon by it, and Argon is effective.
This utility model has a characteristic that
1, adopt the outlet of multiple argon arm, solve single channel tunger tube and be directly blown in tundish argon displacement is not thorough.
2, can according to the distance at the bottom of middle handbag, the appropriate length of design argon arm, it is ensured that argon arm stretches into tundish bottom, so that it is guaranteed that argon is blown into tundish bottom and realizes the lasting blowing argon during the low liquid level of Metal in Tundish.
3, argon distribution header can be directly placed at the plug rod mechanism above tundish or on tundish cover, it is no longer necessary to workman's long-term holding.
4, argon distribution header and connecting tube are by male and female formula snap joint, it is possible to quick despatch, it is possible to Fast Installation connects gas circuit in use, can be dismantled down again placement when not in use.
5, manual ball valve and pressure-regulating valve are installed on gas transmission hard tube, can be used for the switch of argon and pressure regulates.
