Estimating the term…
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.
A method of lubricating a mold for the continuous casting of a metal product, wherein the mold includes a vigorously-cooled vertically-oscillating metal tubular element defining a passage for the cast metal and intended to cause, in contact with its wall in said passage, the solidification of a metal product, and wherein a flow of lubricant in a liquid state is injected through said metal tubular element toward said metal product being solidified, comprising the steps of carrying out said injection 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 wherein 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.
A mold for a plant for the continuous casting of metal products, comprising a vigorously-cooled metal tubular element having a wall defining a passage for a cast metal and intended to cause, as a result of contact with its wall defining said passage, the solidification of said metal, means for vertically oscillating said mold and means for injecting a lubricant in the liquid state through said metal tubular element toward said metal being solidified, wherein said means are placed at a single level of said metal tubular element, said level lying at a distance greater than 20 cm from the lowest level at which solidification of said metal is able to be initiated.
