The invention is directed to a process and to a continuous casting installation for the production of thin slabs, preferably of steel with a predetermined solidification thickness of, e.g., 50 mm, in which an optimum surface quality and internal quality of the strand with minimal and predetermined solidification thickness and plant capacity, and accordingly minimal rolling effort, is achieved by the introduction and optimal combination of such elements as the following: continuous casting and rolling in the region of the strand guide (segment 0), hydraulically driven lifting platform, casting powder and feed thereof, immersion nozzle with specific flow cross section. A qualitative adjustment of the above-mentioned parameters relating to the process and continuous casting installation results in a satisfactory supply of casting slag and bath movement in the cast surface compared with a standard slab with a thickness of 200 mm. These conditions from the crater end to the cast surface exert a direct influence on the superficial and internal quality of the strand and on the reliability of the casting process.
