Abstract
The utility model provides a blow argon ladle lid which characterized in that: including steel shell (1), refractory material (2), be provided with and blow the blowing of argon hole (3) argon ring canal (4) and hoisting machine structure (5), there are perpendicular decurrent guard plate (6), steel shell (1) and guard plate (6) fixed connection in steel shell (1) peripheral 360, be fixed with refractory material (2) below steel shell (1) is positive, be fixed with hoisting machine above steel shell (1) and construct (5), guard plate (6) go up to be connected and to be blown argon ring canal (4), blow to be equipped with on argon ring canal (4) and blow argon hole (3).
Description
Technical field
The utility model belongs to technical field of ferrous metallurgy, is a kind of heat insulation seal device.
Background technology
The steel ladle cover used during current most of steel mill cast is single circular box hat, is attached with asbestos or castable refractory below, steel ladle cover broad in the middle do not arrange argon-blowing device or and small part in the middle of steel ladle cover, be provided with argon-blowing device.Because the splash in smelting process of ladle mouth edge has slag mixture, ladle mouth edge is made not to be very smooth; Or steel ladle cover is out of shape after scorching, after making to cover steel ladle cover, ladle mouth edge leaves gap, and in casting process, air can enter in ladle; Even if be provided with argon-blowing device directly over steel ladle cover, when argon gas arrives steel ladle edge edge, also can be upwards floating, the object of 100% isolated air cannot be played, such as above-mentioned steel ladle cover cannot meet the requirement of isolated air completely, there is the possibility of molten steel secondary pollution in casting process.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of Argon steel ladle cover.
The scheme of the utility model technical solution problem is:
A kind of Argon steel ladle cover, comprises steel shell, refractory material, the Argon endless tube being provided with argon blowing hole and hoisting mechanism; 360 °, steel shell periphery has protective plate vertically downward, and steel shell is fixedly connected with protective plate; Steel shell is fixed with refractory material just below, is fixed with hoisting mechanism above steel shell; Protective plate connects Argon endless tube, Argon endless tube is provided with argon blowing hole.
Preferably, steel ladle cover is oblate cylinder ┏ ┓ shape, and steel ladle cover interior diameter is not less than supporting ladle overall diameter suitable for reading; Argon steel ladle cover is refractory material in the face of the side of ladle mouth, and steel ladle cover shell is steel shell.
Preferably, protective plate is steel or high temperature resistant material.
Preferably, the optional position that the Argon endless tube vertical ring-type protective plate that protective plate connects is upper and lower, uppermost position in fig-ure is not higher than the lower plane position of refractory material.
Preferably, refractory material is at least one in asbestos or castable refractory bi-material.
Preferably, Argon endless tube is provided with argon blowing hole in the face of the side of steel shell.
Adopt and protective plate is set on steel ladle cover periphery, protective plate is provided with multiple argon blowing hole in the face of the side of steel shell, by the argon gas that argon blowing hole blows out, air between steel shell and protective plate is squeezed, make ladle space suitable for reading and ambient atmosphere completely isolated, so just stopped the secondary pollution of outside air to slag or molten steel.The quantity of argon blowing hole can adjust arbitrarily according to the size of ladle diameter, meets blowout argon gas by air exclusion, makes air cannot enter sheaf space on ladle mouth.

Fig. 3 is using state schematic diagram of the present utility model
Wherein, 1, steel shell; 2, refractory material; 3, argon blowing hole; 4, Argon endless tube; 5, hoisting mechanism; 6, protective plate; 7, argon gas; 8, the argon gas ring-type isolation layer ejected; 9, ladle.
Detailed description of the invention
The utility model is made up of steel shell 1, refractory material 2, the Argon endless tube 4 being provided with argon blowing hole 3 and hoisting mechanism 5.360 °, steel shell 1 periphery has the protective plate 6 of ring-type vertically downward, and steel shell 1 is fixedly connected with protective plate 6; Steel shell 1 is fixed with refractory material 2 just below, and steel shell 1 is fixed with hoisting mechanism 5 above; Protective plate 6 connects Argon endless tube 4, argon endless tube 4 is provided with multiple argon blowing hole 3 in the face of the side of steel shell.
By hoisting mechanism 5 steel ladle cover integral hoisting is placed in when using directly over the ladle mouth of casting, then argon gas is opened, make argon gas enter Argon endless tube 4 by pipeline, argon gas sprays from the argon blowing hole 3 Argon endless tube again, forms argon gas ring-type isolation layer at steel shell periphery.The argon gas of ejection is stopped the rear argon gas stream formed and upwards downwards by steel shell, the air part in space suitable for reading for ladle is squeezed by argon gas stream upwards, the air of steel shell periphery squeezes by downward argon gas stream in steel ladle cover protective plate, such argon gas forms isolation layer between steel ladle cover protective plate and steel shell, by ambient atmosphere and steel package space completely isolated, avoid the secondary pollution phenomenon that molten steel produces in casting process.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
