IMPROVED MOULD FOR STEEL CONTINUOUS CASTING, PARTICULARLY FOR THE CONTINUOUS CASTING OF THIN SLABS

摘要

An improved mould, particularly suitable for the continuous casting of thin slabs, shows the wide walls having a profile in a vertical plane being formed of a number of curved lines which are radiused to each other, in particular arcs of circumference having a bending radius of a size decreasing downward from a valueapproaching infinity on the inlet side where the tangent line to the profile is vertical, until reaching with a continuous line the known lower band at the outlet from the mould. The latter is an arc of circumference with the center in the oscillating center of mould, being positioned at a height comprised between the levels of inlet andoutlet sides of the mould itself. Preferably the profile pattern is elliptical starting from the inlet side with vertical tangent down to said lower arc of circumference, so that the bending variation is caused to be tendentially continuous.
