Description
Technical field
The utility model belongs to the improvement of steel mill slab continuous casting submerged nozzle structure, particularly a kind of improved continuous casting
Submersed nozzle.
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
In water, the floating of field trash plays an important role;(4) there is decisive influence to sheet billet continuous casting lumber recovery and slab quality.
Steel mill slab continuous casting submerged nozzle inwall form is cylindric straight up and down at present, and inwall is in casting process
Field trash accumulation is easily caused, is caused the mouth of a river that flow phenomenon is blocked up, so that continuous casting is smoothed out.Due to this kind of submersed nozzle
Design feature, easily cause field trash accumulation using process submersed nozzle inwall, cause mouth of a river inwall dross phenomenon, to even
Casting production has a negative impact.
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
Internal stifled flow phenomenon, is smoothed out having a negative impact to continuous casting.
2nd, submersed nozzle is changed frequently due to inwall accumulation field trash, and the cost of use of resistance to material is higher.
Utility model content
The purpose of this utility model is to provide a kind of improved continuous casting immersion outlet, and which is rational in infrastructure, can improve
Slab invasive nozzle service life, reduces casting process and blocks up flow phenomenon, it is ensured that continuous casting process is smoothed out, and can reduce
Worker's labour intensity, reduces cost.
The purpose of this utility model is realized in：A kind of improved continuous casting immersion outlet, including continuous casting immersion
The mouth of a river, the internal diameter of the pouring spout of continuous casting immersion outlet is 60mm, sets gradually at the middle part of continuous casting immersion outlet pouring spout
The first reducing pipe and the second reducing pipe, the diameter of the first reducing pipe and the second reducing pipe is 40mm, the length of the first reducing pipe
Spend for 200-300mm, the length of the second reducing pipe is 400-600mm, between the second reducing pipe and the first reducing pipe head and the tail between
Away from for 350-500mm.
It is as follows that the utility model mainly improves content：
1st, by raw sheet base submersed nozzle inwall, structure is improved to stepped construction straight up and down, this kind of structure mouth of a river inwall
Field trash is not easy to pile up, and can improve the stifled flow phenomenon of continuous casting process.
Main improvement effect：
1st, as stifled stream number of times reduces after improving, therefore change invasive nozzle number of times and reduce, substantially reduce worker's work
Intensity.
2nd, the accumulation of casting process mouth of a river inwall field trash is reduced after improving and beam blocks up flow phenomenon, it is ensured that casting process
It is smoothed out, improves the operating rate of conticaster.
3rd, the invasive nozzle life-span is improve, 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 of stifled stream replacing, greatly reduces steel technology index.
The utility model is rational in infrastructure, improves slab invasive nozzle service life, reduces the stifled stream of casting process existing
As, it is ensured that continuous casting process is smoothed out, and reduces worker's labour intensity, reduces cost.
Description of the drawings
The utility model is further described below in conjunction with accompanying drawing, Fig. 1 illustrates for the utility model sectional structure
Figure.
Specific embodiment
A kind of improved continuous casting immersion outlet, as shown in figure 1, including continuous casting immersion outlet 1, continuous casting immersion outlet
The internal diameter of 1 pouring spout is 60mm, sets gradually the first reducing pipe 2 and the at the middle part of 1 pouring spout of continuous casting immersion outlet
Two reducing pipes 3, the diameter of the first reducing pipe 2 and the second reducing pipe 3 are 40mm, and the length of the first reducing pipe 2 is 200-
300mm, the length of the second reducing pipe 3 is 400-600mm, and the spacing between the second reducing pipe 3 and 2 head and the tail of the first reducing pipe is
350-500mm.
