Definitions
- the invention relates to a device for the continuous casting of metal, in particular Steel, comprising a lifting table, which is by means of a drive unit can be driven to oscillate, one picked up by the lifting table Continuous casting mold as well as a fixed supporting structure that with Guide or storage elements for dn lifting table is provided.
- Spring systems are known to replace rolling and plain bearings, for example from EP 0 150 357 B1.
- a guide device described for a continuous casting mold with an integrally formed Chill lift table brackets are attached, each via a spring element with a removable frame that can be placed on the base frame are connected.
- These brackets consist of a spring support together, which holds a straight leaf spring, on the one with the intermediate piece connected to the mold lifting table comes to rest.
- the invention has for its object a device for continuous casting for metal, especially steel, with guide elements between the lifting table and a fixed support structure to provide the simple, low-wear and maintenance-free and which are independent of thermal expansions ensure precise guidance of the lifting table.
- a first load balancing system is in the form of a elastic spring system.
- This is made up of two angled arranged in relation to each other - preferably at an angle of 90 ° - spring legs together, each perpendicular to the direction of oscillation extend, the two spring legs designed tuning fork-shaped are and where the overlapping upper and lower Ends of the two spring legs the support surface for the lifting table or form the connection surface with the fixed support structure and the spring system in addition to the force in the direction of oscillation forces in the two receives directions perpendicular to the direction of oscillation vibration.
- the spring system is particularly opposed to the known rolling and plain bearings, maintenance-free storage of guaranteed swinging lifting table on a supporting frame.
- the leadership is free of play because, apart from the elastic deformation of the springs, none Change of barrel geometry takes place.
- the two are tuning fork-shaped trained leg of a spring system in one piece and after a second embodiment formed in two pieces.
- a first outer part is connected to the lifting table, a second outer part to the supporting frame.
- the spring system can be moved by moving the lower two Leg parts are adjusted. Due to different dimensions of the Leaf springs that form the tuning fork in terms of their length, width and Thickness is also the suspension and running accuracy on different Adaptable for use.
