Definitions
- the invention relates to a device for the continuous casting of metal, in particular steel, comprising a lifting table which can be driven in an oscillating manner by means of a drive unit, a continuous casting mold accommodated by the lifting table and a fixed support frame which is provided with guide or bearing elements for the lifting table ,
- Spring systems are known as replacements for roller and plain bearings, for example from EP 0 150 357 B1.
- This describes a guide device for a continuous casting mold, with fixtures being fastened to a mold lifting table in one piece, each of which is connected via a spring element to an interchangeable frame that can be placed on the base frame.
- These brackets are composed of a spring support that receives a straight leaf spring on which an intermediate piece connected to the mold lifting table comes to rest.
- the invention has for its object to provide a device for continuous casting for metal, especially steel, with guide elements between the lifting table and a fixed support frame, which are simple, low-wear and maintenance-free and which ensure accurate guidance of the lifting table regardless of thermal expansion.
- a first load balancing system is designed in the form of an elastic spring system. This is composed of two spring legs arranged at an angle to one another, preferably at an angle of 90 °, each extending perpendicular to the direction of oscillation, the two spring legs being designed in the form of a tuning fork and the overlapping upper and lower ends of the two spring legs form the support surface for the lifting table or the connection surface with the fixed support frame and the spring system absorbs forces in the two directions perpendicular to the direction of oscillation in addition to the force in the direction of oscillation.
- a second conceivable load balancing system is proposed as a pressure-controlled cushion system that is operated with an appropriate medium, preferably air or an appropriate liquid.
- the spring system in contrast to the known roller and slide bearings, ensures that the oscillating lifting table is mounted on a supporting frame in a maintenance-free manner.
- the guidance is free of play because, apart from the elastic deformation of the springs, there is no change in the running geometry.
- the two legs of a spring system designed in the form of a tuning fork are in one piece and according to one second embodiment formed in two parts.
- a first outer part is connected to the lifting table, a second outer part to the supporting frame.
- the spring system can be adjusted by moving the two lower leg parts. Due to the different dimensions of the leaf springs that form the tuning fork, in terms of their length, width and thickness, the suspension and running accuracy can also be adapted to different applications.

- the overall height of the guide columns 91a, 92a is predetermined by the height of the lifting cylinder 4a and that of the mold. With 111a, 112a inlets for the cooling water of the mold are designated.
- Figure 3 shows a side view of the continuous caster, which is rotated by 90 ° to the side views of Figures 1 and 2.
- the two supporting frame elements 2a, 2b each hold a cylinder 4a, 4b.
- a first and a second L-shaped lifting table element 3a, 3b are opposed to each other.
- the two lifting table elements 3a, 3b are shown above, spaced apart and take up the mold 13 with the casting width Y on corresponding support surfaces 122a, 122b. Below the mold outlet, the first segments 142a, 142b are shown, i.e. the first rolls to guide the strand with the shell solidified after it emerged from the mold.
- the two lifting table elements 3a, 3b are shown below the mold outlet, the first segments 142a, 142b are shown, i.e. the first rolls to guide the strand with the shell solidified after it emerged from the mold.
- Each lifting table element 3a, 3b is supported and guided by a total of four spring systems 155, the upper (63a, 64a, 63b, 64b) to the lower ren (61a, 62a, 61 b, 62b) spring systems are arranged offset to one another.
