A crystallizer including a cylindrical body with a bottom, a lid and a vertical shaft which is mounted on bearings and is provided with a rotary drive. The inner surfaces of the body and lid are covered with a two-layer coating. The first layer, in the form of a liner, is attached to the walls of the body by means of a high-temperature adhesive. The second layer is made of fine-grained graphite and is glued to the first layer. The bearings are arranged in a unit which is designed to allow the supply of a cooling liquid. The described subject matter makes it possible to improve the quality of ingots since the thermal deformation of the crystallizer and the interaction of the ingot with the body walls are excluded owing to the increased velocity range of the bearings.
