Description
Technical field
The utility model high-performance steel continuous casting technology field, specifically one kind can effectively solve the problem that plate face junction is close
The continuous casting filling pipe end of the new structure of secondary oxidation of steel under the conditions of sealing and prevent height from even pouring.
Background technology
Steel continuously casting is the main technique of current steel production, the ratio of current steel continuously casting be up to 98% with
On, in addition to extremely indivedual steel grades, general steel grade is all that molten steel is converted into steel billet by continuously casting.But for some property high
Energy steel grade, the selection of refractory material has standard higher in casting process, and ultra-low-carbon steel is poured and cast this problem.Ultra-low carbon
Steel employs special technique in steel-making and refining process, it is ensured that carbon content is less than 300ppm.This steel has fabulous
Deep drawability and ductility（As above the IF steel of th century America Amoca Corp exploitation is used for car panel）, high-strength tenacity energy
（Such as ultra-low-carbon bainite steel, the steel grade can be used for Arctic heavy caliber high pressure oil-gas pipeline）, improve conventional ferrite stainless
The pitting corrosion resistance of steel, toughness and processing characteristics etc.（Such as super-purity ferrite stainless steel）Etc., have in industrial trade very big
Market.
Further raising with the fast development of metallurgical technology and to making the quality requirements such as steel cleanliness factor, in mesh
In preceding continuous casting technology, 100% slab production casting machine employs protective casting, and 70% square billet casting machine also all employs protection
Casting, its protection domain from ladle to tundish, from tundish to crystallizer, in ladle, in tundish and in crystallizer all
Employ coverture in bulk, the covering slag formed with high temperature melting with air insulated layer function.
Filling pipe end is mounted in tundish bottom, in steel pouring process, is subjected to static pressure, the bottom immersion of high-temperature molten steel
The mouth of a river is to its top power from bottom to top, and the disturbance that high temperature, the flow at high speed of high specific gravity molten steel cause.Existing plate face sealing
Due to clamper thrust support area discontinuity, cause poor sealing, there are two defects, one is to cause the mouth of a river pouring steel
During air is sucked due to suction function, cause secondary oxidation to molten steel, influence the quality of steel billet；Two is because plate face is resistance to
Material produces oxidation because of high temperature action again when air is sucked, it is serious in the case of have molten steel by the seam contract after plate face oxidation
Outside is seeped into, causes equipment to be damaged, or even personal safety accident can be caused.
In order to prevent molten steel from being flowed into during crystallizer because filling pipe end and the plate face of submersed nozzle two are combined by tundish
Place seals bad and sucks air and produce secondary oxidation, it is necessary to develop a kind of new structure suitable for continuous casting quick-changing mechanism
Continuous casting filling pipe end.
The content of the invention
The purpose of this utility model is directed to the plate face sealing problem that the Quick change upper nozzle for using in the prior art is present, and carries
For it is a kind of can effectively solve the problem that plate face junction seal and prevent it is high even pour under the conditions of secondary oxidation of steel new structure company
Casting filling pipe end.
The purpose of this utility model is solved by the following technical programs：
A kind of continuous casting filling pipe end of new structure, including filling pipe end and metal can, it is characterised in that：The metal can
The metalwork of one semi-cylindrical is set at clamper thrust support area, the both ends of the surface of the metalwork respectively with the horizontal plane of metal can
Combined with vertical plane close and firm so that all can be distributed in the whole surface of metal can suffered thrust by metalwork,
So that it is guaranteed that the sealing property between the plate face of the filling pipe end plate face of filling pipe end and submersed nozzle below.
The radius R scopes of the metalwork are 5~100mm.
The radius R scopes of the metalwork are 15~20mm.
Described filling pipe end includes filling pipe end pipeline and filling pipe end plate face two parts and both all use high-performance refractory material
Material one cast is formed, and the outer surface of upper of filling pipe end pipeline is in the inclined plane shape for inside contracting.
Described metalwork is located at the concave arc above filling pipe end plate face side.
The size for pouring steel passage of the filling pipe end can make according to sets requirement.
Described metal can is made of the metal material of high-termal conductivity, high temperature tolerance energy, high intensity.
The utility model has the following advantages compared to existing technology：
The metalwork that the utility model passes through one semi-cylindrical of setting at the clamper thrust support area of metal can, the gold
The both ends of the surface for belonging to part are combined with the horizontal plane and vertical plane close and firm of metal can respectively so that metalwork can push away suffered
Power is all distributed in the whole surface of metal can, filling pipe end is had the strong of resistance to mechanical stress higher in steel pouring process
Degree, so as to ensure that the sealing property between plate face, has reached that the air in steel pouring process is not sucked, filling pipe end plate face is not aoxidized,
Finally ensure that the time of direct casting and the quality of steel billet.
