Definitions
- the casting strand 1 is transported therein by means of driven support roller pairs 6, individual support rollers 6a, which can be adjusted, driven or not driven.
- the support roller pairs 6 also form groups 7 of support rollers (FIGS. 2A and 2B) or support roller pairs 7a.
- the inflow of the liquid steel material can also be regulated via various plug positions 8.
- the melt pool level 9 is regulated in the continuous casting mold 4. All of the elements, components or functions described have signal transmitters 10.
- the roller spacing is set via hydraulic piston-cylinder units 11, in whose cylinder spaces such signal transmitters are also arranged are.
- the signals from the signal generators 10 are routed to a central memory and computer unit 12.
- the support roller segments 5 also form a fixed side 13a (left side) and a loose side 13b (right side).
