Abstract
The subject of the invention is a method of lubricating a mold (1) for the continuous casting of a metal product (16), of the type including a vigorously-cooled vertically-oscillating metal tubular element (2) defining a passage (4) for the cast metal and intended to cause, in contact with its wall (3) in said passage, the solidification of said metal product, in which a lubricant in the liquid state is injected through said metal tubular element toward said metal product being solidified, wherein said injection is carried out at points distributed annularly at a single level of said tubular element, said level lying at a distance greater than 20 cm from the lowest level at which solidification of said product is able to be initiated, and in that the flow rate of said lubricant is sufficient to cause a fraction of said lubricant to rise up along said wall to the level at which solidification of said product is effectively initiated.
