Description
Technical field
The utility model to relate in ingot steel casting process the argon gas device that steel pouring stream is protected, and belongs to ingot steel casting equipment technical field.
Background technology
Before ingot steel casting, molten steel in ladle is through refining, application of vacuum, the indexs such as Molten Steel Cleanliness, composition, temperature have reached technological requirement, but in ingot steel casting process, steel stream can be there is directly contact with air, cause secondary oxidation of steel and molten steel air-breathing, easily cause steel ingot internal soundness to fluctuate, main manifestations is ingot butt lamination defect.Simultaneously; at present in process of production; non-standard ingot shape, the different ingot shape output of same dish have accounted for more than 56%; therefore in casting process; frequent generation ingot mould and the unmatched phenomenon of middle cast tube height; cause ladle nozzle and cast tube basin brick apart from inconsistent, fluctuate between 200 ~ 450mm, molding casting effect is undesirable.In addition, argon shield adopts bottled argon gas, and bottled argon pressure is unstable, and early stage is high, and the later stage is low, cannot realize constant voltage cast.Therefore; in order to effectively avoid molten steel directly to contact with air, and then alleviating secondary oxidation of steel, reduction molten steel inspiratory capacity, significantly reducing ingot butt lamination defect incidence; steel ingot internal soundness is tended towards stability, is necessary to improve the proterctive equipment in pouring molten steel process.
Utility model content
Technical problem to be solved in the utility model is to provide the argon protective device in a kind of ingot steel casting process; this argon protective device can implement molding casting to molten steel, effectively avoids steel stream to contact with air, alleviates secondary oxidation of steel; reduce molten steel inspiratory capacity, stablize ingot quality.
The technical scheme solved the problems of the technologies described above is:
A kind of ingot steel casting argon protective device; it has the ring sleeve of a level; ring sleeve is enclosed within ladle nozzle circumference; ring sleeve is fixedly connected with ladle nozzle; ring sleeve there is air inlet be connected with argon gas pipeline; the bottom of ring sleeve is evenly distributed in steam vent along ring sleeve, adds protection steel cage in ring sleeve periphery.
Above-mentioned ingot steel casting argon protective device, the top of described protection steel cage is connected with ladle nozzle above ring sleeve, protects the horizontal plane of lower end plane lower than ring sleeve of steel cage.
Above-mentioned ingot steel casting argon protective device, it to water steel vehicle seat bag support pad be adjustable shim, the distance between ladle nozzle and cast tube basin brick is within 150-200mm.
Above-mentioned ingot steel casting argon protective device, is provided with pressure-regulating valve door in argon gas pipeline.
The beneficial effects of the utility model are:
The utility model has installed ring sleeve additional around ladle nozzle, and argon gas is protected the steel stream below ladle nozzle by the steam vent of ring sleeve bottom, effectively avoids molten steel directly to contact with air, alleviates secondary oxidation of steel, reduces molten steel inspiratory capacity; Install protection steel cage additional and can prevent steam vent steel bonding, improve ventilative vitality; Regulate the ducted pressure-regulating valve door of argon gas can realize constant voltage argon for protecting pouring; Water steel vehicle seat bag support pad by adjustment, make ladle nozzle and cast tube basin brick distance controlling within 150-200mm, further enhancing protected effect of the present utility model.The utility model structure is simple, protected effect good, reduces ingot butt lamination defect rate, improves comprehensive flaw detection qualification rate and Extra Sensory Perception flaw detection qualification rate, decrease mass loss, have significant economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: wrap greatly 1, ladle nozzle 2, ring sleeve 3, steam vent 4, protect steel cage 5, argon gas pipeline 6, pressure-regulating valve door 7, argon gas 8.
Detailed description of the invention
The utility model comprises ring sleeve 3, protection steel cage 5.
Show in figure; ring sleeve 3 is horizontal positioned; ring sleeve 3 is enclosed within ladle nozzle 2 circumference; ring sleeve 3 is fixedly connected with ladle nozzle 2; ring sleeve 3 there is air inlet be connected with argon gas pipeline 6; the bottom of ring sleeve 3 is evenly distributed in steam vent 4 along ring sleeve; steam vent 4 sprays argon gas 7 downwards; argon gas 7 is looped around ladle nozzle 2 around; steel stream below ladle nozzle is protected; effectively avoid molten steel directly to contact with air, alleviate secondary oxidation of steel, reduce molten steel inspiratory capacity.
Show in figure, add protection steel cage 5 in ring sleeve 3 periphery, the top of protection steel cage 5 is connected with ladle nozzle 2 above ring sleeve 3, protects the horizontal plane of lower end plane lower than ring sleeve 3 of steel cage 5.Protection steel cage 5 can prevent steam vent 4 steel bonding of ring sleeve 3, improves ventilative vitality.
In argon gas pipeline 6 of the present utility model, pressure-regulating valve door 7 being installed, constant voltage argon for protecting pouring can being realized by regulating the pressure-regulating valve door 7 in argon gas pipeline 6.Pressure 0.1-0.4Mpa in argon gas pipeline 6 is adjustable, and in casting process, by technological requirement, by regulating pressure pipeline valve 7, optimum pressure is 0.2Mpa.
The utility model also will water steel vehicle seat bag support pad and change adjustable shim into, water steel vehicle seat bag support pad by adjustment, make ladle nozzle 2 and cast tube basin brick distance controlling within 150-200mm, further enhancing protected effect of the present utility model.
After the utility model is implemented, reduce by 0.09% through measuring and calculating ingot butt lamination defect rate average level, comprehensive flaw detection qualification rate specific mass improves 0.25% stationary stage, and Extra Sensory Perception flaw detection qualification rate promotes 4.6%, and year reduces mass loss 151.68 ten thousand yuan.
