Process and installation for continuous casting thin metallic products between rolls

摘要

Molten metal is poured into a casting space bounded by the cylindrical surfaces of two counter-rotating rolls (1,1') and two lateral retaining walls (3), and a thin solidified prod. is extracted from this space. A measured thrust is exerted on the retaining walls (3) parallel to the roll axes, in order to press them against the roll faces (11). The drag on each retaining wall in the direction of the casting motion is measured. The measured values of thrust and drag are used to derive a quantity which is indicative of the friction conditions in the contact zone between the retaining walls and cylinder faces. This quantity is compared with a predetermined value, and the comparison result is used for control of casting parameters.
