Description
Technical field
The utility model belongs to the improvement of steel mill slab continuous casting submerged nozzle structure, particularly a kind of to carry horn mouth
Continuous casting immersion outlet.
Background technology
Slab continuous casting submerged nozzle main function is:(1) splashing of secondary oxidation of steel, nitridation and molten steel is prevented;(2)
Adjust MOLTEN STEEL FLOW state and injection rate;(3) covering slag and other non-metallic inclusions is prevented to be involved in molten steel, to promoting steel
The floating of field trash plays an important role in water;(4) there is decisive influence to sheet billet continuous casting lumber recovery and slab quality.
Current steel mill slab continuous casting submerged nozzle inwall form is cylindric straight up and down, and inwall is in casting process
Field trash accumulation is easily caused, causes the mouth of a river to block up flow phenomenon, prevents continuous casting from being smoothed out.
Due to the design feature of such a submersed nozzle, field trash heap is easily caused using process submersed nozzle inwall
Product, causes mouth of a river inwall dross phenomenon, has a negative impact to continuous casting.
The subject matter that traditional slab invasive nozzle is present is as follows：
1st, invasive nozzle inwall is cylindrical shape, and inwall easily causes field trash accumulation in casting process, causes the mouth of a river
The stifled flow phenomenon in inside, is smoothed out having a negative impact to continuous casting.
2nd, submersed nozzle changes frequent, the cost of use of resistance to material is higher due to inwall accumulation field trash.
Utility model content
The purpose of this utility model is to provide a kind of with bell-mouthed continuous casting immersion outlet, its conjunction simple in construction
Reason, dependable performance can improve slab invasive nozzle service life, and reduction casting process blocks up flow phenomenon, it is ensured that continuous casting
Process is smoothed out, reduction consumption, is reduced worker's labor intensity, is reduced cost.
What the purpose of this utility model was realized in：One kind carries bell-mouthed continuous casting immersion outlet, including continuous casting
Submersed nozzle, the mouth of a river bore of continuous casting immersion outlet is 60mm, sets expanding in the lower end of continuous casting immersion outlet
Cylindrical drum, the internal diameter of expanding cylindrical drum is 100mm, and length is 400mm, and wherein continuous casting immersion outlet pouring spout passes through transition circle
Taper Pipe connects expanding cylindrical drum, and the length of transition conical tube is 200-250mm.
Operation principle of the present utility model：
By raw sheet base submersed nozzle inwall, structure is improved to from top to bottom gradually expanding loudspeaker to the utility model straight up and down
Mouth structure, such a intraoral wall field trash of constitution water is not easy accumulation, can improve the stifled flow phenomenon of continuous casting process.
The good effect that the utility model is produced：
1st, flow phenomenon is blocked up in the accumulation and beam that casting process mouth of a river inwall field trash is reduced after improving, it is ensured that casting process
It is smoothed out, improves the operating rate of conticaster.
2nd, because stifled stream number of times reduces after improving, therefore replacing invasive nozzle number of times is reduced, and substantially reduces worker's work
Intensity.
3rd, the invasive nozzle life-span is improved, the production cost of sheet billet continuous casting is reduced, cost is compared and reduced compared with before-improvement
About 30% or so.
4th, invasive nozzle is reduced because the frequency that stifled stream is changed, greatly reduces steel technology index.
The utility model is simple and reasonable, dependable performance, and slab invasive nozzle service life can be improved by realizing,
Reduce casting process and block up flow phenomenon, it is ensured that continuous casting process is smoothed out, and reduces consumption, reduce worker's work strong
Degree, reduces cost.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is that sectional structure of the present utility model shows
It is intended to.
Embodiment
