Abstract
The utility model provides the outside argon-blowing device of the large bag long nozzle of a kind of continuous casting, comprise the argon gas pipeline be arranged on long nozzle operator jaw and the argon gas source of the gas be connected with described argon gas pipeline, described tunger tube road shape size and described long nozzle operator jaw adapt, and are evenly provided with some argon gas exports along self circumference.The utility model effectively to reduce in casting molten steel process due to the air that the negative pressure of gap position sucks, prevents air to the secondary oxidation of molten steel, improves Molten Steel Cleanliness, thus the quality of raising strand.Simultaneously this apparatus structure is simple, easy for installation, can recycle, and maintenance cost is low, it is little to invest.
Description
Technical field
The utility model belongs to metallurgical machinery continuous casting installation for casting field, relates to the outside argon-blowing device of the large bag long nozzle of a kind of continuous casting.
Background technology
Molten steel is in the large bag casting process of continuous casting, and long nozzle and collector nozzle of ladle connecting portion have gap, and this place is easy to suck air due to the impact of negative pressure, produces secondary pollution to molten steel.Present iron and steel enterprise generally gets down to and reduces long nozzle and collector nozzle of ladle gap and carry out blowing argon in long nozzle inside to solve the problems referred to above.But fail so fundamentally to solve the air of molten steel owing to sucking in casting process, affect the problem of slab quality, and need to carry out larger change to production equipment, significantly improve cost.
Utility model content
The technical problems to be solved in the utility model is to provide the outside argon-blowing device of the large bag long nozzle of a kind of continuous casting, and object forms argon gas atmosphere in long nozzle outside, effectively reduces because of long nozzle and the large air wrapping lower gap, mouth of a river place and suck, improves the quality of strand.
To achieve these goals, the technical scheme that the utility model is taked is:
The outside argon-blowing device of the large bag long nozzle of described continuous casting, comprise the argon gas pipeline be arranged on long nozzle operator jaw and the argon gas source of the gas be connected with described argon gas pipeline, described tunger tube road shape size and described long nozzle operator jaw adapt, and are evenly provided with some argon gas exports along self circumference.
Described argon gas pipeline is C font, and the centre of described argon gas pipeline is provided with the gas source interface be connected with described argon gas source of the gas.
Adopt technique scheme, argon gas forms argon gas atmosphere by argon-blowing device in long nozzle outside, reduces the contact of molten steel and air, better improves steel quality.And this apparatus structure is simple, can reuse again, greatly reduce costs compared to existing technology.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model;
Fig. 2 is the schematic diagram of the utility model when installing and using.
Being labeled as in figure:
1, argon gas pipeline; 2, argon gas export; 3, gas source interface; 4, large bag long nozzle; 5, long nozzle operator.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.
As shown in Figure 1 and Figure 2, the utility model provides the outside argon-blowing device of the large bag long nozzle of a kind of continuous casting, comprises argon gas pipeline 1 and argon gas source of the gas.Described argon gas pipeline 1 geomery and described long nozzle operator jaw 5 adapt, and are C font.Argon gas pipeline 1 is evenly provided with 10 argon gas exports 2 along self circumference, is provided with gas source interface 3 in centre position.Argon gas source of the gas is connected to gas source interface 3 by flexible pipe.
After argon-blowing device completes, in use argon gas pipeline 1 is arranged on long nozzle operator jaw 5, during cast, is placed in large bag long nozzle 4 place.Before cast, open the high pressure gas holder valve as argon gas source of the gas, connect argon gas, check argon gas export 2 whether normal ventilation.Continuous aeration during cast, argon gas is ejected in large bag long nozzle 4 surrounding through argon gas export 2 and forms argon gas curtain protection molten steel.After cast terminates, close argon gas source of the gas, and inspection is repaiied to argon-blowing device, in order to recycling.
This device effectively to reduce in casting molten steel process due to the air that the negative pressure of gap position sucks, prevents air to the secondary oxidation of molten steel, improves Molten Steel Cleanliness, thus the quality of raising strand.Simultaneously this apparatus structure is simple, easy for installation, can recycle, and maintenance cost is low, it is little to invest.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
