"Axial mold movement device of continuous casting plants"

The permanent casting mold is known to be in one Lifting table mounted, which carries out an up and down movement by suitable means to prevent the liquid metal solidified in the edge zone due to the cooling of the mold sticks to the mold wall «,

Efforts were made to control the movement of the lifting table and mold to prevent tilting in the axial direction as far as possible, »Various guide or attachment devices are required for this purpose of the lifting table has become known, which are sometimes complex and sometimes not entirely accurate in their Leadership caused difficulties in pulling the rope.

It is important that the lifting table is guided precisely in a straight line during the execution of its oscillations, with signs of wear and tear in the straight lines and the effect of the bearing play contribute significantly to deviations in the straight line (DAS 1 162 036, 1 151 $ 54 and 1 235 516).

Albeit with regard to another known construction

is alleged that canting of the mold table by the movement of the lifting table by means of levers on the side Endings cannot occur, it should be pointed out that through the arc deflection the lever that thru ^ h the bearing play is compensated, no Gq-pqntie for the exact axial movement is given (DAS 1 176 800).

As particularly strict when creating hollow streams Standards for the rectilinear movement of the mold have to be applied to the continuous flow by no means To interfere with damage to the strand, the aim of the invention is to put the lifting table with the mold in such to displace axial vibrations that do not allow any deviations from the linear movement »

According to the invention, the lifting table is suspended in such a way that the lifting table is guided by a link system which generates a lemniscate curve known per se, from the almost straight part of which the desired lifting table movements are derived.

In a further embodiment of the invention, the mounting of the pivot points in preloaded roller bearings is used to eliminate any bearing play, so that the guarantee is given to set the mold vibrating without deviating from the required straight line.

The construction of the lifting table with the LemniSkaten effect can be done in different ways.

"For example, referring to the accompanying drawings two possibilities "described, the presentation according to "Pip-o 1 and Fig. 2 one possibility and according to Fig. 2 and Figo 5 illustrates another possibility, with each di.p- Fd doors. 1, 2 and 3> 4- show the side and top views of the constructions.

Bi? The bracket construction shown in Fig. 1 sees the suspension of the lifting table 1 on a total of eight, four each above and below, in each case opposite pins in front, the link system being formed from the tabs 3 »4 · will ο

The tabs are at one end in the bolt 5, respectively associated with the spawning 3. The other ends are the same pivoted by the bolts 6 in bearings 7, the latter being attached to the framework of the casting plant; , qir) d "

The drive takes place from the crank 8 via the push rod 9, what "? connected to a double lever 11 by the bolt 10 is. The latter is pivotably mounted in the bearing 12.

The exiting strand 15 is shown in FIG.

The second way of a handle embodiment shown in FIGS 3 and 4 x, the same effect _ö generated Here, the lifting table 1 with a total of eight lagerst ^ 'CKEN 16, provided with bolts 17 _5, four each in the upper and lower part to which the handlebar systems, consisting of tabs 1 "and 19 are attached",

The tabs 19 are on the one hand by the bolts 20 to the Lugs 18 and, on the other hand, hinged to the bearings 22 with bolts 21, which are attached to the frames of the casting plant are ο

For the drive, as in the first version; Seen a crank 8, push rod 9, connected by Eolzen 10 with a double lever 11, which is pivotable in the bearing 12 is arranged. Via a tab 23, with a double lever 11 hinged in the bolt 24, the transmission goes to the two Pin 25 on the lifting table 1.

With the application of the lemniscate effect known per se by a link system of, for example:] Designs for the purposes of a lifting table movement including the casting of hollow strands, the guarantee is given that the lifting table and thus the mold will result in a deviation of the guided suspension points the ahirpseings and strokes required for this purpose from the straight line b ^ wepunp has only been achieved in values that can no longer be measured, i.e. ^{practically equal to 1 nuIl »}

Since the play that occurs in the bearings was eliminated by preloaded roller bearings, this is no longer the case
Side no more influence possible, so that the continuous flow of the casting process, especially "in the production of hollow strands, resistances, which could result from tilting of the mold, no longer stand in the way."
