Description
Technical field
The utility model belongs to the improvement of the steel base brick structure that steel mill is used, it is particularly a kind of can be with the ladle of Argon
Pocket block.
Background technology
Ladle is used to make steel to be accepted molten steel before electric furnace or converter, carries out pouring practice.Liquid is contained as steel making working procedure
How the container of molten steel, play its metallurgical function to greatest extent, is always steel-making worker's concern.Ladle bottom is pacified
Dress brick cup, the built-in water inlet of brick cup enters tundish for molten steel by the mouth of a river.
The steel base brick for originally using due to there is gap, therefore pouring molten steel process and air contact and the mouth of a river between,
The oxidation of molten steel is easily caused, causes increasing for molten steel subscale field trash, not only form dross phenomenon smooth to continuous casting
Cast is adversely affected, and causes the rising of continuous casting billet inner clamps debris, influences continuous casting billet quality.
The subject matter that traditional ladle pocket block is present is as follows：
1st, due to there is gap, therefore pouring molten steel process and air contact between pocket block and the mouth of a river, easily cause
The oxidation of molten steel, causes increasing for molten steel subscale field trash.
2nd, the field trash that content is higher in molten steel forms dross phenomenon, and dross thing is enriched in ladle nozzle constantly to be piled up,
Mouth of a river aperture is caused to be plugged, cast smooth to ladle is adversely affected.
3rd, the continuous oxidation of molten steel causes Tundish during Continuous Casting constantly to aoxidize, the rising of continuous casting billet inner clamps debris,
Influence continuous casting billet quality.
Utility model content
The purpose of this utility model be provide it is a kind of can be with the ladle pocket block of Argon, its is rational in infrastructure, can make
Molten steel surface in casting process covers one layer of argon shield, and effective isolation molten steel and air reduce molten steel and be oxidized
Degree, reduce the high-melting-point field trash in molten steel in the enrichment of middle water containing opening, contribute to continuous casting to be smoothed out, can be with
Improve continuous casting process, improve continuous casting billet quality, reduce the labour intensity of staff.
What the purpose of this utility model was realized in：It is a kind of can be with the ladle pocket block of Argon, including with disk
The cylinder barrel shaped ladle pocket block of seat, sets upright gas transmission road and from upper in the cylinder barrel of ladle pocket block
Horizontal communication gap uniform down, upright gas transmission road is connected with uniform horizontal communication gap respectively, is set in disc seat
Air intake duct is put, air intake duct is connected to gas transmission road, and the import of air intake duct is connected to supply argon gas pipeline.
Main improvement content is as follows：
The pre-buried Argon pipeline inside ladle pocket block, molten steel flow process in the mouth of a river is passed through argon gas, in molten steel liquid
One layer of argon gas is covered on face, because argon gas is inert gas, therefore air-isolation can be played a part of, prevent molten steel by air
Secondary oxidation.
Improvement effect
1st, the continuous Argon of MOLTEN STEEL FLOW process in ladle nozzle, is passed through argon gas, and one layer of argon gas is covered on molten steel surface,
Play a part of to completely cut off air, prevent molten steel from being aoxidized by air secondary.
2nd, the ladle pocket block that can be blown of new design can substantially reduce casting process molten steel by air secondary oxygen
The degree of change, reduces the high-melting-point field trash in molten steel in the enrichment of middle water containing opening, contributes to continuous casting to be smoothed out.
3rd, prevent from entering the secondary oxidation of Tundish during Continuous Casting, reduce the quantity of continuous casting billet inner clamps debris, it is ensured that
Continuous casting billet quality.
4th, argon-blowing device is easy for installation, and personnel need to only install argon-blowing device pipe joint, it is possible to decrease staff's
Labour intensity.
The utility model is rational in infrastructure, the molten steel surface in casting process is covered one layer of argon shield, effectively
Completely cut off molten steel and air, reduced the oxidized degree of molten steel, reduce the high-melting-point field trash in molten steel in tundish water
The enrichment of mouth, contributes to continuous casting to be smoothed out, and improves continuous casting process, improves continuous casting billet quality, reduces work
Make the labour intensity of personnel.
Brief description of the drawings
The utility model is further described below in conjunction with accompanying drawing, Fig. 1 illustrates for the utility model sectional structure
Figure.
Specific embodiment
It is a kind of can be with the ladle pocket block of Argon, as shown in figure 1, including the cylinder barrel shaped ladle water with disc seat 2
