Abrégé
A process and 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 a qualitative adjustment of casting and rolling in the region of the strand guide, oscillation of the casting mold by a hydraulically operated lifting platform, feeding of casting powder to the mold, and an immersion nozzle with a specific cross sectional area of flow relating to the process and continuous casting installation, resulting 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.
