Technical field
The utility model relates to a kind of ten second-rate conticaster tundish, belongs to tundish apparatus technical field.
Background technology
Along with the development of steel-smelting technology, the cleannes of steel are required to improve constantly.The metallurgical link having necessitated of bag in continuous casting, in conjunction with the needs of producing, tundish plays vital effect to removing the mean residence time of molten steel in non-metallic inclusion, even liquid steel temperature, balanced multi-strand tundish.In the middle of multiple-strand caster, be surrounded by present both at home and abroad five streams, six streams, eight streams etc., be up to ten second-rate.In multi-strand tundish, when desirable state is the optimization that realizes tundish flow field, the balanced respectively average stop between stream, asks and respectively flow temperature, will be beneficial to so respectively to flow successfully to open and water and normal cast.At present general tundish is difficult to reach, and does not also have document to use for reference both at home and abroad.The main cause that is difficult to reach above-mentioned perfect condition is, first from shock point to the distance at a mouth of a river farthest, has more than 6m, so flow field control difficulty is very large; Secondly because ten second-rate square billet casting machine tundish high-temperature molten steel in casting process often washes away more severe to the 6th stream of adjacent large water-coating port and the 7th stream stopper bottom, resistance to material corrodes serious, therefore current ten second-rate conticaster tundish can not meet the needs of production, and are necessary to be improved.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of ten second-rate conticaster tundish of energy reasonable diffluence, this tundish can reasonable layout molten steel, and extend time of staying of molten steel, and alleviate the wash away erosion of molten steel to stopper, solve billet continuous casting and open the front flow control problem of watering.
The technical scheme solving the problems of the technologies described above is:
A kind of ten second-rate conticaster tundish of energy reasonable diffluence, it is comprised of two tundish symmetries, each tundish is by tundish body, clad, stopper, brick cup, composite nozzle, the lower mouth of a river forms, on tundish body, there are permanent layer and working lining, position in the every first-class cast in the bottom of tundish is all provided with brick cup, composite nozzle is installed in brick cup, composite nozzle above and stopper cooperation, be connected with the lower mouth of a river below, its improvements are, an all-in-one-piece turbulence inhibitor is installed in tundish, turbulence inhibitor is positioned at the below of large bag long nozzle, the tapping mouth of a river of large bag long nozzle is relative with the upper opening of turbulence inhibitor, on the side barricade in the district that becomes a mandarin of turbulence inhibitor, have pod apertures, pod apertures is towards other stream away from large water-coating port pouring position.
Ten second-rate conticaster tundish of above-mentioned energy reasonable diffluence, described pod apertures is two, and horizontal symmetrical distributes, and the tapping direction of two pod apertures is tilted to, and angle of inclination and horizontal direction are 12-30 °, the aperture of two pod apertures is 100-200mm.
Ten second-rate conticaster tundish of above-mentioned energy reasonable diffluence, the stopper of described each stream and composite nozzle junction are provided with to open waters ring.
The beneficial effects of the utility model are:
The utility model has adopted monoblock type turbulence inhibitor, prevent that high-temperature molten steel from directly entering 6 streams or 7 flowing water mouths, thereby alleviate the wash away erosion of molten steel to stopper, two pod apertures of turbulence inhibitor can make molten steel raise up, pod apertures is towards other stream away from large water-coating port pouring position, be convenient to be uniformly distributed molten steel toward each stream, and extend the time of staying of molten steel; In the stopper of each stream and composite nozzle junction, be provided with to open and water ring, raised region, the mouth of a river, can prevent from wrapping the resistance to material of wall, remaining bulk cargo or other foreign matters assembles at the place of becoming a mandarin, the mouth of a river of lower, can prevent in baking of tundish process the foreign matter place's high temperature bonding that becomes a mandarin at the mouth of a river simultaneously, solve billet continuous casting and opened the front flow control problem of watering.The utility model is simple in structure, be easy to make, there is anti-turbulence effects good, can there is not impact zone liquid steel level slagging scorification phenomenon, can also suitably reduce the impact kinetic energy of large bag beam, and the kinetic energy that fluid replacement moves ahead in process is not enough, prevent that the unreasonable situation of the flow location form causing because fluid is discontinuous from occurring, and can reasonably control molten steel and distribute.
