Description
Outokumpu Oy Apparatus for -the continuous casting of an object of predetermined weight or size The present invention relates to an apparatus for -the continuous cas-ting of a plate-like object of predetermined weight or size, such as an anode plate, in-to open, low-rimmed molds at the periphery of a rota-ting wheel, the apparatus comprising at least one casting ladle for pouring molten metal into the molds, a feediny member for filling the casting ladle with molten metal between castings, measuring devices for determining the total weight of the casting ladle before and during casting, and control members for regulating the casting cycle on the basis of the measured total weight of the casting ladle.
Previously known apparatus of the above type, e.g. suspended and weighed casting ladles above a continuously rotating casting wheel, have been s-tructurally unsui-table for foundry conditions.
The object of the present 'nvention is to provide a casting apparatus fitted in connection with a continuously rotating casting wheel and using previously known casting and ~Pighing ~l - ~
.
techniques experimented with in practice.
A continuously rotating wheel has certain advantages in terms of castin~ techniques and apparatus technology, but it also has grea-t drawbacks, e.g. in removing the cast anodes from the wheel~ The present invention comprises only a practical me-thod of ca~i.ng flawless p:l.ates of a precise wei~Jht while the table is .in continuous rotation.
According to the invention, this is achieved using an apparatus in which the casting ladle has been fitted to swivel between two extreme posi-tions around a subs-tantially vertical shaft so that -the spout of the casting ladle moves along with the mold below it at a given moment during the casting cycle and then re-turns to a position above the next mold before the following casting cycle. Thus the movement oE the series oE molds can be continuous, in which case no splashing of the molten metal in a mold owing to acceleration or braking will occur, and furthermore, the molten metal is poured into the mold by a dependable, tried technique, which makes it possible to pour the molten metal into the mold with a minimum quantity of casting burr.
The essential idea of the invention lies in the fact -that, contrar~ to what ~ould be assumed without a thorough knowled~e of the pouring action into -the mold, splashing over the mold rims in the lateral direction is not caused by the pouring even if the casting ladle is only a few centime-ters from the mold rims.
In other words, cen-tering the casting ladle in the lateral direction is not the most critical factor.
On the other hand, the distance of the castincJ edge from those rims of the mold which are parallel to the casting edge is critical. For this reason the previously known system, in which the pouring edge of the casting ladle is parallel to the radius of the wheel, the ladle being on top of the table and either fixed, or in some embodimen-ts moving with the wheel, provides no advantage in terms of the pouring action itself. In this method, however, the structures of the appara-tus are complicated and expensive, as well as difficult to use in production conditions.
The apparatus according -to -the invention can be made very simple and advantageous as the casting ].adle, the measuri~ng devices and the control members constitute one swiveling unit which can be :Eitted :ins:icle the mold circle, p.re.Eerably so that the substantially vertical swivel sha:Et oE the casting ladle is coaxial wlth the turnin~ po:int o:E the casting wheel.
The invention is described below in more detail with reference to the accompanying drawinq, in which Fi.gure 1 depicts a side elevation of the apparatus according to the invention, Figure 2 a top view of the apparatus, and Figure 3 a section along line A-A in Figure 1.
In the drawings, the endless, circular series of molds rotating in the horizontal plane is indicated by reference numeral 1 and the low-rimmed molds, open a-t the top, situated in it are indicated by 4. The casting uni-t fitted adjacent -to the mold circle 1, outside its periphery, is indicated by 2, and its purpose is to pour a precisely weighed quantity of molten metal into each mold 4 in turn. The batching ladle situa-ted on the opposite side of the castlng unit 2 in relation to the mold track 1 is indicated by 3, and i-ts purpose is to allow a periodic flow of a molten metal quantity sufflcient for filling at least one mold 4 into the casting ladle 5 in the casting unit 2. During filling the casting ladle 5 is in its basic position, shown in Figure 1, and the batching ladle 3 is in the position indicated by the dotted outline in Figure 1.
The casting unit also has scales 9 measuring the total weight of the casting unit. On the basis of a signal given by the scales 9 the batching ladle 3 is raised when a sufficient quantity of molten metal has flown into the casting ladle 5.
The casting ladle 5 has been fitted in the casting unit 2 so that it can be tipped, supported by a horizontal shaEt 6 in such a manner that the molten metal contained in it can be ~3~8S;~
poured` through the spout 7 into the mold 4 below when the castiny ladle 5 is tipped. The castlng unit 2 is also supported by a bearinq 8 so as -to swivel around a substantially vertical shaft 11; thus the casting unit 2 swivels be-tween -two extreme positions,which are indicated in Figure 2 by solid and dotted lines, respectively. The swivel movemellt of the casting unit is procluced by the actuating cylinder 12 shown in Figure 3, one end oE the cylinder being attached to arm 13 protruding radially from the shaft 11 and the other end to the Erame.
The apparatus according to the invention also has control devices (not in the Eigure), by means of which the tipping of the batching ladle 3 and the castin~ ladle 5 and the swivel movement of the casting unit are controlled and coordinated.
In addition, the casting unit 2 has been fitted with a cover 14 which has been fi-tted next to the casting ladle 5 and swivels, supported by the arm 16, around a vertical shaft 10; a burner 15 has been fitted to the cover 14. The cover 14 can be swiveled above the s~out 7 of the casting ladle to keep the molten metal in it hot so -that the molten met~l will not cool before or during casting.
When the casting ladle has been filled with a sufficient quantity of molten metal and the batchinq ladle 3 has been raised, the cas-ting ladle 5 swivels about its horizontal shaft 6 to lower the spout 7 so that molten metal flows into the mold 4 below. At the same time the entire casting unit is swiveled about its vertical shaft 11 by the actuating cylinder 12, supported by the bearing 8, so that the spout 7 follows the movement of the mold below during the casting cycle. When the scales 9 indicate that the total weight of the casting unit 2 has decreased sufficiently, i.e., by the predetermined weight of the molten metal to be poured into the mold, the casting ladle 5, supported by its hori~ontal shaft 6, returns to its basic position, whereby its spout 7 rises and cuts the flow of molten metal into the mold 4. At the same -time the ac-tuating cylinder 12 returns the casting unit to its initial position to fill the casting ladle with a new batch of molten metal.
