The trolleys ingot molds can be constructed with different materials, by means of welded profiles, and mounted on four or six wheels that run on rails. The tightening of the ingot can be either mechanical or hydraulic. In the first case the molds are clamped by means of mechanical locking screw, in the second case the hydraulic system includes two opposed hydraulic jacks.
This unit allows the casting and solidification of ingots from 1 to 5 Kg and is composed of three units: Unit for the Preheating of the ingot molds, equipped with a device to control the solidification of the metal by means of air/LPG flame switched by photoelectric cells. Unit for Ingots Solidification constituted by a Copper Table, water cooled, used during the casting of molten metal.
