A process for strand casting of steel in a cooled casting mold made to oscillate over a distance h at a frequency f, for manufacturing a product withdrawn from the mold at a casting speed VC, the metal being surmounted by alubrication product forming a liquid slag, the speed of descent of the casting mold being greater than the casting speed VC during a negative stripping time tN. The casting speed VC can be adjusted over a wide range to adapt to well-defined casting conditions without modifying the nature of the lubrication product, by acting in a combined way on the distance and frequency of oscillations according to the chosen casting speed, in such a way that the consumption rate Q of the lubrication product and the negative stripping time tN are both maintained at an optimum value that remains substantially constant over the entire speed adjustment range, irrespective of the casting speed VC.
