Definitions

• the invention relates to a device for the support and oscillation of a continuous casting mold for casting of liquid metal, in particular of flüssi ⁇ gem steel material, arranged on both sides to a plane of symmetry, in which the Mittel ⁇ longitudinal axis of the cast strand, arranged guide elements arranged on stationary support components are stored, wherein the continuous casting mold is supported on both sides on guide elements and at least one oscillating device.
• Such devices move large masses, which consist of the weight of the continuous casting mold with side walls (narrow side plates), a Stitzkonstruk ⁇ tion for the side walls, for water tanks, a lifting table with both sides an ⁇ ordered guide elements and oscillating drives. Added to this is the frictional force between the cast strand surfaces and the mold walls during the downward stroke of the oscillatory drives.
• the support of such devices is generally very difficult and also requires a high Platz ⁇ required, so that the accessibility of the loaded by wear assemblies and components is difficult.
• a lengthy dismantling or mounting exchangeable or serviceable components means an equally long-term stoppage of the continuous casting machine. This creates significant economic disadvantages.
• the invention is based on the objective of shortening the maintenance, disassembly and assembly times by a corresponding constructive design and thereby reducing downtime and costs.
• the object is achieved according to the invention in that a first assembly of guide elements and supporting components is formed and a second assembly consists of the oscillation, wherein the second assembly by a lateral, transverse to the plane of symmetry output or input below the guide elements or between Füh- management elements is removable and wherein each of the two modules in time and place regardless of the other module is disassembled or reassembled.
• the main advantage is achieved in that regardless of whether an assembly for guide elements or the oscillation device has to be changed more frequently, the shorter maintenance or changeover time can be used in each case because a certain sequence of successive removal actions is no longer compulsory , The module can immediately be removed and rebuilt, which requires maintenance. Furthermore, there are advantages to the effect that disassembling and mounting without prior maintenance does not create a requirement for a new alignment or adjustment of the respective different type of assembly, which is not affected by disassembly, assembly or maintenance.
• One embodiment is directed to the reduction of the masses to be moved and thus to the reduction of the stress on the components and provides that the first assembly with brackets of a self-supporting Strangg screen ⁇ kokille is supported and fixed on the guide elements on spaced bearing blocks.
• the number of components can be reduced by the fact that the bearing blocks each together form a one-part wall frame, which are each supported and fastened in pairs on an intermediate plate.
• the assembly of the supporting components is characterized in particular in the total absence of a lifting table or a correspondingly heavy frame in that the first assembly also includes a cover plate and a support plate with guide thorns for the continuous casting mold.
• a portion of the otherwise forciblymutbau- to be removed components during maintenance, disassembly or assembly so was ⁇ were ⁇ that a stationary assembly of a lower plate, several Stütz ⁇ walls and an intermediate plate is formed on a continuous casting ⁇ stationary stationary, releasable base plate is arranged.
• Easier accessibility of the stationary support members is further achieved in that on the intermediate plate on both sides free spaces for the oscillatory movements of leaf spring-shaped guide elements are arranged.
• the entire number of components can be assembled by fixing the fixed, detachable subassembly on the fixed base plate by means of ground screws.
• the removal or replacement of the oscillation drive which may include pairs of oscillation devices, requires integration into the fixed region and provides that the oscillation device in each case in the Grenzbe ⁇ rich between the first expandable assembly and the stationary assembly on a flange plate is supported.
• a lighter, faster and more complete removal or installation provides that the second expandable assembly comprises at least one oscillation device with the piston-cylinder drive and control or switching elements.
• the cooling zone of the strand casting mold for which a stationary structure with cooling water connections is provided on the intermediate plate.
• the number of components or subassemblies to be removed can be increased if necessary to such an extent that the stationary subpanel and the intermediate plate with the superstructures form a stationary, detachable subassembly which is lifted or placed by means of lifting eyes.

• the cylinder or the piston of the piston-cylinder drive 6a can be gewech ⁇ Selt. It is also essential that each of the two modules can be disassembled and remounted independently of each other in terms of time and location.
• the first assembly 7 need not be removed. Conversely, the The entire hydraulic circuit of the second assembly 8 remain in the Vorrich ⁇ device and does not need to be opened when only Wartungsarbei ⁇ th on the first assembly 7 are executed.
