Abstract
Continuous casting T shape tundish impact area argon-blowing device, in continuous casting of molten steel equipment, relates in particular to a kind of continuous casting T shape tundish protection cast argon-blowing device.Feature is that this device consists of framework, air supply pipe, Argon pipe, fast joint and nozzle, and air supply pipe is established in the outside of described framework, and the head of air supply pipe is established fast joint, by wireway, ball valve and argon gas source of the gas, is connected, and Argon pipe and nozzle are established in framework inner side.Before cast, on device placement and T shape tundish impact area refractory material cylinder-packing, fast joint is connected with wireway, and ball valve is controlled charge flow rate; During cast, argon gas is sprayed by nozzle, at impact zone, forms air curtain, isolated air conservation molten steel; After cast, take off device.Advantage is novel, and structure letter gathers, rationally; Can effectively completely cut off molten steel the contacting of middle bag impact zone and air, prevent molten steel secondary oxidation in casting process, improve Molten Steel Cleanliness, thereby improve the quality of strand; Design apparatus is simple in structure, easy to operate, can reuse, and invests little.
Description
Technical field
The utility model belongs to continuous casting of molten steel equipment, relates in particular to a kind of continuous casting T shape tundish protection cast argon-blowing device.
Background technology
Along with high-quality steel is continually developed, also more and more higher to the degree of purity requirement of steel, wherein in casting process, secondary oxidation is one of key factor affecting purity of steel.Steel production enterprise is generally added a cover and is carried out blowing argon T shape basket pouring region now at present; but shock zone does not take to protect apparatus for pouring; molten steel is just easy ingress of air in casting process; the easy ingress of air in territory, T shape tundish impact area; the easy oxidation by air of molten steel; produce secondary pollution, affect slab quality, increase production cost.
Utility model content
In order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of continuous casting T shape tundish impact area argon-blowing device, can in casting process, effectively completely cut off molten steel and contact with air, improves the quality of strand.
Continuous casting T shape tundish impact area argon-blowing device, comprise wireway and be located at the ball valve on wireway, be characterized in that this device consists of framework, air supply pipe, Argon pipe, fast joint and nozzle, air supply pipe is established in the outside of described framework, the head of air supply pipe is established fast joint, by wireway, ball valve and argon gas source of the gas, connected, Argon pipe and nozzle are established in framework inner side.Before cast, on device placement and T shape tundish impact area refractory material cylinder-packing, fast joint is connected with wireway, and ball valve is controlled charge flow rate; During cast, argon gas is sprayed by nozzle, at impact zone, forms air curtain, isolated air conservation molten steel; After cast, take off device.
The utility model further improves, described framework is connected and composed by hollow pipe, framework and T shape tundish impact area shape, size match, framework inner side is uniformly distributed at least eight Argon pipes, Argon pipe one end is welded on framework, be communicated with the through hole on framework, the other end is established screw thread, connects with nozzle; In the middle of framework, establish the air supply pipe with fast joint, fast joint connects rapidly, facilitates mobile T shape tundish.
The utility model further improves, and described nozzle consists of taper inner and outer tubes, in taper inner tube, establishes stepped hole, taper inner tube peripheral hardware external screw thread; In outer tube, establish spray orifice and taper inner tube adapts, in spray orifice, establish internal thread, match with taper inner tube peripheral hardware external screw thread; The installation end of outer tube is established external screw thread, is connected with Argon pipe, in use procedure, as situations such as obstructions, can change easily, guarantees to protect effect.
Compared with prior art, advantage is novel, and structure letter gathers, rationally; Can effectively completely cut off molten steel the contacting of middle bag impact zone and air, prevent molten steel secondary oxidation in casting process, improve Molten Steel Cleanliness, thereby improve the quality of strand; Design apparatus is simple in structure, easy to operate, can reuse, and invests little.
