Abstract
A process and apparatus for producing thin metal products by continuous casting. The apparatus comprises an ingot mold (2) and squeezing rolls (6, 6') intended to cause, by reduction of the thickness of product, closing of the solidification pool. The separation force (F) exerted on the squeezing rolls by the product is measured and a variable magnetic field, matched to the separation force so that the latter does not exceed over a long period a predetermined upper limit value representing the force that the squeezing rolls can tolerate temporarily without damage, is applied to the core of the still molten product by inductors (8, 8') housed in, or upstream of, the squeezing rolls.
