A three dimensional model for studying the surface shape of the rolls textured by laser beam is set up. The fluid motion in the melt pool and the deformation of the liquid gas interface in addition to the heat transfer for the laser remelting is taken into account. The surface shape of the melt pool is numerically approached. The shape of the surface of the laser textured rolls is compared with the numerical results, having good agreement with the height, depth and width.
