Definitions
- lance noses work at a distance of bath from 1 to 2.5 m, while the bath has a temperature of the order 1400 ° C. Under these operating conditions, the temperature of the nose can grow quickly at 400 ° C, and have to stay in this environment for about 20 minutes. Then, when the spear is removed, the nose quickly returns to room temperature, that is, to 20 ° C.
- the present invention aims to propose a nose of launches who is able to undergo the important solicitations to which he subject to a significant number of successive uses, all by providing a simple lance nose to manufacture and defensible cost.
- a nose of blow lance as described at the beginning, wherein said third front wall has a central depression which is directed towards central opening and which has a ratio between height of depression and base of depression equal to or greater than 0.35, said second front wall has, around the central opening, a central deformation in the form of a truncated cone, which is directed towards said first front wall, and space heat exchange has a section for the passage of the coolant which is substantially constant so as to get a coolant flow velocity through this space which is approximately constant, in the presence of depression.
- said central depression has a ratio of height to base equal to or greater than 0.4, in especially at 0.5, and preferably even at 0.8.
- section for the passage of liquid from “cooling” means that the affected sections are taken perpendicular to the flow direction of the coolant in the heat exchange space.
- the flow / section ratio remains constant and therefore the speed of passage of the liquid also remains constant. It can thus be ensured that at a given speed of passage, and at the critical temperature of the front wall to be cooled, none Cavitation phenomenon is not likely to occur in the liquid of cooling, which generally is water.
- a flow rate of the flow liquid between 8 and 12 m / sec.
- the nose of lance comprises several aforementioned passage conduits arranged around of a central axis and in that said central depression extends from said outlet ports of these conduits.
- the basis of depression is thus advantageously maximum and allows improved efficiency of heat exchange in the depression.
- the third end wall has an outer diameter and the base of said depression is a circle with a diameter of at least 0.25 x said outer diameter, preferably at least 0.33 x this diameter external.
- the central depression is thus not according to the invention in any way a small central recess laid out in the wall of the nose for strengthen the rigidity of it.
- said third front wall has a depression central cone-shaped.
- said cone and said truncated cone have a common axis and the central depression in cone shape forms with this axis an angle greater than the formed angle between this axis and the central deformation in the form of a truncated cone.
- the section can remain constant and the flow velocity of the flow liquid also remains equivalent to that obtained along the entire third front wall.
- the central depression is at least partially covered by a screen protector made of a material with high thermal resistance. It could be a disc-shaped plate that is carried by the depression central or tight against it and therefore requires no welding for its fixation. Thermal exchange between the coolant and the third front wall remains unchanged, while a large part the area of the third end wall is protected from overheating excessive.
- a spear nose 1 of FIG. blowing This nose includes a central tube 2 for the gas supply brewing.
- This central tube 2 is closed by a front wall 3 which, in the illustrated example, is provided with several openings 4.
- An inner tube 5 is arranged coaxially around of the central tube 2 and these tubes form between them an annular cavity 6 which, in the example illustrated, is used to supply water to cooling in the direction of arrow F ,.
- This inner tube 5 is closed by a front wall 7 which is called a separator.
- This wall 7 is provided with a central opening 8 and an orifice 9 in the alignment of each opening 4 in the central tube 2.
- An outer tube 10 is arranged coaxially around the central tube 2.
- This outer tube is generally made of steel and forms with the inner tube 5 an annular cavity 11 which, in the example illustrated, serves for the outlet of water from cooling in the direction of the arrow F 2 .
- This outer tube 10 is closed by a front wall 12 which faces the bath to be stirred and which is therefore subjected to critical thermal stresses, as explained above.
- this front wall is made of a material that is a good conductor of heat, for example copper, to allow as efficient a heat exchange as possible between the heated front wall 12 and the cooling water passing through the heat exchange space. 13 which is located between the front wall 7 of the inner tube 5 and the front wall 12 of the outer tube 10.
- the cooling water coming from the cavity 6 passes through the central opening 8 in the heat exchange zone 13. There it flows in the direction of the arrow F 3 outwards, that is to say towards the cavity 11.
- the front wall 12 is also provided with an outlet orifice 14 in alignment with each opening 4 provided in the front wall 3 and with each passage opening 9 provided in the front wall 7.
- a conduit output 15 for the ejection of brewing gas outside the nose of spear.
- the outer front wall 12 is, according to the invention, provided in its center of a cone-shaped depression 16, which is directed towards the central opening.
- this depression is sufficiently pronounced to present a ratio between height of the inner wall of the cone (h) and base diameter (B) equal to or greater than 0.35. In the case illustrated this ratio is equal to about 0.5.
- this depression 16 extends from the ducts output 15 and therefore forms a cone whose base is maximum.
- the ratio between the base B of the depression and the outer diameter D of the front wall 12 is about 0.33. Otherwise, by the deep depression, the central zone of the frontal wall 12, which is the most thermally stressed, is discarded at maximum of the bath surface.
- Figure 3 illustrates how to measure the parameters h and B of the lance nose according to the invention.
- the height h is calculated between, on the one hand, the tangent plane lower 30 of the lance nose perpendicular to the axis 19 and the parallel plane 31 tangent to the top of the depression. If something foreign to the depression is expected at the top of it, such as the pulling 20 in Figure 2, the plane 31 remains in the position it would have if this foreign element did not exist. The summit of depression must be then considered as a virtual point to be taken into account in the measured.
- the base B is located in the lower tangent plane 30. It is circumscribed by line 32 resulting from the intersection between this plane 30 and the extension 33 of the internal faces 34 of the depression. We do not hold therefore no rounding counts.
- the outer diameter of the front wall 12 is taken where its value is maximum.
- This deformation 17 has a frustoconical shape open upwards through the central opening 8.
- This truncated cone 17 is coaxial with the cone formed by the depression 16, their common axis being the axis 19 of the lance nose.
- the cone of the depression 16 forms with the axis 19 an angle greater than the angle formed between this axis and the imaginary extension of the truncated cone 17 up to this axis.
- the truncated cone 17 is further away from the cone 16 at its summit than at its base. At its summit, the truncated cone is narrower. So, the section of the heat exchange space located between the front walls 7 and 12, which is measured in a plane perpendicular to the flow direction of the coolant, remains constant even in the presence of the projected central depression 16 in the exemplary embodiment illustrated in FIG.
- the lance nose according to the invention is therefore arranged in order to provide for the full extent of the heat exchange zone 13 a constant passage section for the coolant.
- this ratio corresponding to a speed of passage of the flow liquid expressed in m / sec.
- the flow and the section will be determined to obtain a speed of approximately constant passage and between 8 and 12 m / sec. The phenomenon of cavitation can thus be avoided as much as possible. greatly improves the efficiency of the heat exchange obtained in the nose.
- FIG. represented a lance nose that is different from the one depicted on the Figure 1 in that the depression 16 is more pronounced.
- the top of the depression 16 protrudes through the opening 8 and opens therefore even in the space between the front walls 3 and 7, which allows to obtain a ratio between h and B equal to or greater than 0.8.
- a retaining element for example a tie rod 20, between the top of the vacuum and a nut arranged on or in the front wall 3 of the tube central 2.
- the central depression 16 is, in this exemplary embodiment, completely covered by a plate 21 thermally resistant. In this way, while allowing a unchanged heat exchange between the cooling water and the cone formed by the depression 16, the central part of the lance nose is thermally insulated from the heat of the bath, which enhances the efficiency of heat exchange and allows a longer life of the nose of spear.
- plate 21 is composite, that is to say it has a layer outer part of a refractory material, for example ceramic, or refractory steel and an inner layer of thermally insulation, such as fibrous alumina.
- a refractory material for example ceramic, or refractory steel
- an inner layer of thermally insulation such as fibrous alumina.
- this plate is simply tight between the head 22 of a threaded rod 23 passing through the plate 21 and screwed in a thread provided in the head of the tie rod 20.
- Other modes of fixing this plate could of course be provided.
- the lifetime of a nose is calculated on the number of cast that could be brewed before having to discard this nose. As can be seen from this table, the improvement in the average duration of life of the nose according to the invention is remarkable and totally unexpected.
