Definitions
- the contact surface between the mold and cooling device is subjected to a reduced pressure by a vacuum transmitted through apertures in the cooling device which communicate with the contact surfacel
- the mold can also be sealed to the atmosphere and supplied with nitrogen to prevent oxidation where graphite molds are used.
- the invention relates to an apparatus and method for continuous casting of metals. More particularly, the invention relates to an apparatus and method having at least one mold cooled by a surrounding cooling device.
- :It is another object of the invention to maintain a continuous contact surface between a mold and a surrounding cooling device during a continuous casting process.
- the invention provides a method of maintaining the contacting surfaces of a mold and a cooling device surrounding the mold in intimate contact with each other during a casting operation. Intimate contact is maintained by producing a reduced-pressure between the surfaces of the mold and cooling device which has an effect of drawing the mold onto the cooling device.
- the adjacent surfaces of the mold and cooling device thus are always in complete contact so as to avoid the formation of air gaps therebetween while insuring a good uniform heat transfer during each phase of the casting operation.
- the method of the invention is particularly advantageous in the continuous casting of strips since the molds for such have a large width and thus a large heat transfer surface.
- the apparatus of the invention includes a cooling device for surrounding a mold of a continuous casting device wherein the contacting surfaces of the mold and cooling devices communicate through a plurality of apertures within the cooling device with a means for generating a reduced-pressure.
- FIG. 1 illustrates a cross sectional view of a mold and cooling device of the invention
- FIG. 2 illustrates a view taken on line A-B of FIG. 1;
- FIG. 3 illustrates a cross sectional longitudinal view of a modification of the invention.
- a cooling device having an upper part 1 and a lower part 2 held together, for example, by bolts (indicated by broken lines 3) is secured around a mold 4.
- the mold 4 is likewise divided into upper and lower parts to define a hollow internal longitudinal space 5 which serves to form a strip shaped cast strand.
- the upper and lower parts 1, 2 are each provided with chambers 6 through which cooling medium, such as water, oil or the like, flows in a manner not shown in detail.
- a plurality of apertures 7 are formed in the upper and lower parts 1, 2 of the cooling device between the mold 4 and the chambers 6 in each respective part 1, 2.
- the apertures 7 are uniformly distributed over the cooling device and communicate at one end with the contact surfaces 8, 9 between the mold 4 and the respective parts 1, 2 of the cooling device.
- the opposite ends of the apertures 7 communicate with a series of passages 10, 11 in each respective parts 1, 2 of the cooling device.
- the passages 10, 11 which are disposed, for example, transversely of the longitudinal axis of the mold 4 are interconnected by a respective transverse passage 12, 13 which is disposed, for example, longitudinally of the mold axis at one side of the cooling device.
- Each transverse passage 12, 13 is connected through a bore 14 in the cooling device and a pipe 15 (shown diagrammatically) connected to each bore 14 with a reduced-pressure generating suction means, for example, a vacuum pump 16.
- the reduced-pressure generating means creates a reduced pressure, for example, of 7 p.s.i., across the contacting surfaces 8, 9 between the mold 4 and each of the parts 1, 2 of the cooling device.
- the effect of such a reduced-pressure is that the mold 4 is maintained flush with the parts 1, 2 of the cooling device along the contact surfaces 8, 9 so that a good uniform heat transfer from the mold to the cooling device is constantly provided.
- the formation of air gaps in the contact surfaces 8, 9 is prevented even if the walls of the cooling device in which the apertures 7 are formed are slightly deformed, as by bending, since the adjacent mold walls will also be subjected to similar deformation.
- Each part 1, 2 of the cooling device is provided with apertures 7 which are cylindrically formed along their lengths on the left of each part, as shown in FIG. 1, and apertures 7 which are conically widened at their ends adjacent the contact surfaces 8, 9 on the right of each part, as shown in FIG. 1.
- the conically widened apertures provide an increase in the suction area between the contact surfaces 8, 9 so that a greater suction force per aperture is created to press the mold 4 against the cooling device. It is noted in this regard that the reduced pressure is substantially uniform in each of the apertures of the cooling device. It is further noted that since the heat transfer from the mold to the cooling medium (e.g.
- the mold 4 can be formed of a material such as, graphite or a cermet (sintered compound of metallic and ceramic substance). Where the mold material is graphite, the invention can be advantageously improved by feeding nitrogen to the exit of a cast strand from the mold 4.
- a mold of graphite which is connected to a furnace 26 is surrounded by a cooling device as described above having upper and lower parts 1, 2 with cylindrically formed apertures 7 and by a housing 20 mounted on the exit end of the mold.
- the housing 20 is connected to a supply of nitrogen 21 (schematically shown) and surrounds a solidified strand 22 emerging from the mold.
- a labyrinth seal or gland 23 is provided between an inwardly directed wall of the housing 20 and the casting 22.
- Nitrogen is supplied to a pair of passages 24 in the housing 20 which distribute the nitrogen through a plurality of ports 25 into the interior of the housing 20 over the width of the strand 22.
- the nitrogen is fed under a slight excess pressure to prevent in a simple manner contact of the graphite of the mold with the atmospheric oxygen of the surrounding atmosphere so that oxidation of the graphite is avoided. Due to the gas porosity of the graphite, the supplied nitrogen passes through the mold and is drawn off by a reduced-pressure generating means acting on the mold as described above.
- the molten metal or metal alloy in the furnace which is to be cast enters the mold 4 at the end connected to the furnace, solidifies under the action of the cooling device, and is continuously or discontinuously drawn out by means (not shown) from the mold in the direction indicated by the arrow 27.
- the apertures 7 need not be formed in the walls of the cooling device. Instead, individual plates which are to be considered as componnts of a cooling device can be provided between a mold and the remainder of the cooling device. These plates are formed of heat conducting material and are provided with apertures 7 together with transverse connecting passages 10, 11 as described above. If desired, the apertures 7 can extend through the entire depth of thicknesses of the plates so that a reduced-pressure will act both on the contact surface between plate and mold as well as on the contact surface between plate and the remainder of the cooling device.
- the invention provides for the simplified construction of a mold. For example, when casting broad strips, it is no longer necessary to manufacture the mold over the entire width from a simple piece. Rather, the mold of the invention can be assembled from several narrower pieces which together extend over the entire width of the strand to be produced since the mold portions lying side by side are safely and permanently held against a cooling device under the reduced-pressure created by the reduced-pressure generating means of the invention. Likewise, the same principles apply to molds for the casting of strands which have square or rod-like cross sections rather than the cross sections of strips. In casting these square or rod-like strands, the mold can be assembled from four separate parts which bound the four sides of the square or rod-like cross section and which are then held in a surrounding cooling device by means of the reduced-pressure generating means of the invention.
- a continuous casting apparatus comprising a mold having a space therein for forming a strand therein;
- cooling device surrounding said mold for cooling a casting therein, said cooling device and mold defining a contact surface therebetween;
- suction means for generating a reduced-pressure
- said means communicating said suction means with said contact surface further includes a plurality of passages interconnecting said apertures in rows within said cooling device, at least a pair of transverse passages interconnecting said passages, and pipe means connecting said transvere passages with said suction means.
- An apparatus as set forth in claim 1 further comprising a housing mounted on one end of said cooling device for surrounding a cast strand emerging therefrom in sealed relation, and means for connecting the interior of said housing to a nitrogen supply.
