The invention discloses a steel plate
ingot casting device, which comprises a pedestal, a fixed framework and an
ingot mold, wherein the fixed framework is fixedly connected with the pedestal; the
ingot mold is positioned in the fixed framework and consists of two pairs of side templates, i.e., front, rear, left and right side templates, and a bottom template; the outer sides of the side templates and the bottom template are respectively provided with a cooling water box; the side templates are provided with squeezing mechanisms; the bottom template is provided with a lifting mechanism; the side templates and the bottom template are all
copper plate products; and the bottom template is provided with a runner port. According to the steel plate
ingot casting device, deformation under cold and hot intensity stress can be avoided, and a shrinkage hole is avoided; since the solidification time is greatly shortened, the segregation in a steel ingot can be obviously relieved, thereby greatly improving the
internal quality and the performance of a produced ultra-
thick plate; and meanwhile, the steel plate
ingot casting device has the advantages of freely adjustable ingot mold size, long service life of the ingot mold and the like.
