Definitions
- the invention relates to a casting-rolling system for producing a steel strip according to the preamble of claims 1 or 2, and a corresponding method according to the preamble of claim 10.
- a technology for producing cast strip from a molten metal is known, for example from WO 2014/049150 A1.
- a molten metal passes through a casting gap delimited by two counter-rotating casting rolls and is thereby formed into the cast strip.
- two axially parallel and internally cooled casting rollers rotate in opposite directions to one another, which delimit the long sides of a casting gap between them.
- the casting gap is usually sealed by plates made of a refractory material.
- Sufficient liquid melt is poured into the casting gap so that a so-called “melt pool” forms above the casting gap and is maintained until the casting process is completed.
- the melt that reaches the casting rolls from the melt pool solidifies into a shell, which is then conveyed into the casting gap by the respective casting roll.
- the shells are then pressed against each other in the casting gap so that the cast strip is formed from them and the melt trapped between them.
- the cast strip that continuously emerges from the casting gap in this way is drawn off below the casting rolls and fed to the roll gap of a rolling mill for further processing at a lower level.
- FIG. 8 A conventional casting-rolling system according to the prior art is shown in principle simplified in the side view of FIG. 8, which is a typical production system for steel strip.
- the difference in height between the casting rolls of the Twin-Roller and the floor of the rolling mill is, for example, 5000 mm.
