No. 455,481 Claims priority, application Germany, May 15, 1964, B 76,787 12 Claims. (Cl. 164-158) ABSTRACT OF THE DISCLOSURE A strip-casting apparatus for casting of metals, which comprises a stationary frame and a substantially horizontal reciprocable continuous mold having an upper part and a lower part. The latter has a form complementary to the profile of the metal strip to be cast. An inlet funnel is disposed adjacent the mold and is adapted to feed liquid metal into the mold. The lower part of the mold extends to a lower part of the funnel. The mold has cooling conduits extending therethrough. A rotatable metal feeding roll is disposed above the lower part of the mold and has a plurality of cooling conduits. The surface of the metal feeding roll is formed complementary to the profile of the metal strip to be cast.
The present invention relates to a continuous strip-casting apparatus for casting of metal.
The known strip-casting apparatus is operated generally by means of vertically disposed molds. Depending upon the congealing or solidification conditions to which the metal to be cast has to be subjected, such arrangement requires often considerable structural heights, which require corresponding tall buildings. In order to avoid these structural heights, such arrangements have already been built into deep pits.
During strip casting of steel, wherein the structural height is much larger than during the working with other metals, caused by the long liquid funnel, it is also known already to bend over the cast strips into the horizontal direction under the transport rolls, an expedient Which is possible due to the then still prevailing strip temperature.
Furthermore, an installation is known for the manufacture of metal bands, e.g. a copper band, in which installation the metal is crystallized onto a cooled rotating drum immersed into a liquid metal bath. It is, however, not possible to produce other semi-finished products as bands.
It is one object of the present invention to provide a strip-casting apparatus which avoids the drawbacks of the known structures.
It is another object of the present invention to provide a strip-casting apparatus for casting of metals, which is of a horizontal arrangement.
It is a further object of the present invention to provide a strip-casting apparatus, wherein the lower part of the mold, equipped with cooling conduits, extends up to the lower part of an inlet funnel and a metal feeding roller, provided with cooling conduits, is disposed in front of the shorter, upper part of the mold, which is formed according to the profile of the metal strip to be cast, the surface of the metal feeding roller being formed likewise according to the metal strip to be cast.
It is yet another object of the present invention to provide a strip-casting apparatus, wherein a packing of refractory, plastic and metal repelling mass is provided between the inlet funnel, the advanced lower part of the mold and the metal feeding roller, in order to protect the metal feeding roller in front of the liquid metal and in the advanced lower part of the mold.
It is still another object of the present invention to provide a strip-casting apparatus which includes a brush arranged on the upper part of the periphery of the metal feeding roller adapted for the cleaning of the surface of the metal feeding roller and which provides simultaneously a spraying device for the application of the mold lubricant, while a feed conduit for the mold conduit is arranged in the advanced lower part of the mold.
It is also a further object of the present invention to provide a strip-casting apparatus which includes a lifter formed according to the profile of the metal strip between the metal strip and the metal feeding roller at the upper part of the mold, in order to prevent the surface of the metal strip, which surface is only thinly solidified due to the cooling effect of the cooled metal feeding roller, being broken up again by the metal feeding roller.
It is of advantage to provide a joint drive for the transport roller and the metal feeding roller, in order to obtain a synchronous rotational speed for both rollers. It is possible, however, to provide individual drives for the transport roller and for the metal feeding roller, and the synchronous rotational speed can be achieved by means of a common electrical control means.
With these and other objects in view, which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawings, in which:
FIGURE 1 is a longitudinal sectional view of a horizontal strip-casting apparatus according to the present invention along the lines 11 of FIG. 2;
FIG. 2 is a top plan view of the apparatus disclosed in FIG. 1;
FIG. 3 is a section along the lines 3-3 of FIG. 1; and
FIG. 4 is a fragmentary section along the lines 4--4 of FIG. 1.
Referring now to the drawings, the strip-casting apparatus comprises an inlet funnel 2 over which the liquid metal 1 is fed by means of a ladle (not shown) or by means of a teeming furnace in a free fall over a pouring device or over a direct connection (not shown) into the apparatus, which liquid metal 1 is covered by a protective mass 3, in order to prevent oxidation. A skimmer 4 prevents that slag or oxides enter in an unwarranted manner the liquid metal 1.
The mold, consisting of two parts 5 and 6, which are rigidly connected together and which perform a reciprocating movement during the casting, is set-off in its upper part 5 at the entrance point for the liquid metal 1 corresponding to the profile of the metal feeding roll 10 over the upper part 5 of the mold, while the lower part 6 constituting the inlet part, is advanced to the inlet funnel 2. The inlet funnel 2, as well as the metal feeding roll 10, perform the reciprocating movements of the mold during the casting by using any conventional means therefor.
The upper part 5 of the mold is, however, set-off along the center line of the profile, in case of the use of round cross-sections. The metal feeding roll 10, equipped with cooling tubes 9, is arranged in front of the set-off upper part 5 of the mold, which metal feeding roll 10 is formed according to the profile 7 of the metal strip 8. The metal feeding roll 10 engages at its lower engaging point the surface of the metal strip 8, rotates in the direction of movement of the latter and drives forwardly the latter in this manner.
The metal feeding roll 10 is sealed off toward the liquid metal 1 in the inlet funnel 2, as well as: in the advanced lower part 6 of the mold by means of a packing 11 made of a refractory, metal-repelling plastic mass. The mold lubricant, required for the sliding of the metal strip 8 in the mold, is fed for the upper part of the metal strip 8 by means of a spraying device 12 to the metal feeding roll 10, which is cleaned by a rotating brush 13, and reaches with the latter the surface of the metal strip 8. The mold lubricant for the lower part of the metal strip 8 is fed into the mold by means of a feeding conduit '14 terminating in the advanced part 6 of the mold.
' In order to prevent the surface of the metal strip 8, which is only thinly solidified, due to the cooling effect of the cooled metal feeding roll 10, being broken up again by the metal feeding roll 10, a lifter 15 is provided on the set-off edge of the upper part 5 of the mold.
The mold which is cooled by a coolant fed through conduits 16, is secured to a lifting slide 18 mounted in the machine frame 17, which lifting slide 18 is driven by a controllable drive 19 by means of the drive shaft 20 and the pushand connecting rods 21.
The metal strip 8, which is on the outside already completely solidified, moves from the indirect cooling zone in the mold into a zone 22 providing direct cooling by means of spraying nozzles 23, by which the coolant is sprayed on, where the metal strip 8 is completely solidified and is maintained by non-driven support rolls 24 still in horizontal position.
Transport rolls 25, which have the same rotational speed as the metal feeding roll 10, caused by a common drive 26 or also by individual, yet common electrically controlled drives, move the metal strip 8 in dependency upon the profile 7 of the metal strip 8, the type of metal cast and the casting speed from the mold to the further working stations.
In the joint drive 26 of the transport rolls 25 and of the metal feeding roll 10, the drive of the metal feeding roll 10 takes place over the drive shaft 27 and any suitable transmission 28.
While I have disclosed one embodiment of the present invention, it is to be understood that this embodiment is given by example only and not in a limiting sense, the scope of the present invention being determined by the objects and the claims.
