Abstract
The utility model discloses a baking air-inducing device at the bottom of a ladle. The device includes a slide gate arranged at the bottom of the ladle, which is characterized in that the slide gate is connected with an ejector by a connecting sleeve. The ejector comprises an air inducing pipe, an air outlet, and a compressed air pipe, one end of the air inducing pipe is connected with the connecting sleeve, another end is communicated with the air outlet, one end of the compressed air pipe is connected into the air inducing pipe, another end is connected with a compressed air generating device by a valve. The utility model is simple in structure, and reasonable in design. When the gas at the top burns, the air at the bottom of the ladle is extracted by the air inducing pipe, therefore improving the flowing of the heat in the ladle and distributing the heat into each part of the ladle, improving the baking effect, avoiding the steel setting, and improving the work efficiency.
Description
Technical field
The utility model belongs to steelmaking equipment, relates in particular to a kind of blower unit of using at the bottom of the molten steel jar jar that toasts.
Background technology
The molten steel jar is toasted, realize that red jar of tapping is to reduce tapping temperature, shorten smelting cycle, improve a very important operation in furnace life.It is energy-conservation that this not only is related to operation, also is related to water steel quality.The molten steel tank roasting device that we adopt at present utilizes gas-fired to toast from the molten steel tank top.Because tank body is big, be subjected to the restriction of capacity of equipment again, flame can't be baked to the bottom of tank body, causes the tank base cured effect bad, and, there is steel with fixed attention at a jar end, oneself waters rate thereby influence BOTTOM ARGON BLOWING effect and molten steel jar, influences the production direct motion.
Summary of the invention
Thereby the purpose of this utility model is toasted blower unit at the bottom of being to provide a kind of molten steel jar jar that can make the interior baking heat of molten steel jar arrive jar end raising cured effect.
The baking blower unit is achieved in that this device comprises the slide gate nozzle of molten steel pot bottom at the bottom of the utility model molten steel jar jar, is characterized in being connected with an injector by adapter sleeve in the outlet of described slide gate nozzle.Described injector is made up of air inducing pipeline, air outlet and compressed air line, one end of air inducing pipeline is connected with adapter sleeve, the other end communicates with air outlet, and compressed air line one termination is gone into the air inducing pipeline, and the other end is connected with compressed air generator by valve.
The utility model is simple in structure, and is reasonable in design, after the gas-fired at top, the air of molten steel pot bottom is drawn by the air inducing pipeline, has improved flowing of jar interior heat, makes heat can be distributed to jar interior each position, improve cured effect, avoided coagulating the generation of steel, improved working efficiency.
Description of drawings
The utility model accompanying drawing is the structural representation of baking blower unit at the bottom of the molten steel jar jar.
Embodiment
The utility model will be further described with reference to the accompanying drawings.
The baking blower unit has utilized the principle of induction apparatus at the bottom of the utility model molten steel jar jar, and the outlet of the slide gate nozzle 2 at the bottom of molten steel jar jar is connected with an induction apparatus by adapter sleeve 3.Described induction apparatus is combined by air inducing pipeline 4, air outlet 5, compressed air line 6 and compressed air generator 7.One end of air inducing pipeline 4 links to each other with adapter sleeve 3, and the other end communicates with air outlet 5, and an end of compressed air line 6 inserts air inducing pipeline 4, and the other end is connected with compressed air generator 7 by valve.When molten steel jar 1 is toasted, adapter sleeve 3 is socketed in the outlet of slide gate nozzle 2, open the pressurized air valve, utilize compressed air energy to produce suction by air outlet 5, at the bottom of hot gas in the molten steel jar 1 is drawn onto jar, and,, draw from air outlet 5 through adapter sleeve 3 and air inducing pipeline 4 by slide gate nozzle 2.
Claims (2)
