A method of producing a multilayer ingot in an electron-beam installation, with the billet arranged in a base plate above the bottom thereof, and the base plate is reciprocated in a horizontal direction as said billet is being melted and the first layer of said ingot is being shaped. Another metal billet is melted above an intermediate vessel, with the molten metal being poured thereoff onto said first layer of the ingot in the base plate forming thereby a second layer on the first formed layer and additional layers of a multilayer ingot are shaped in a similar manner. The reciprocation speed of the base plate is inversely proportional to the cooling rate of the ingot metal in a longitudinal direction. The method of the invention ensures producing ingots with a smooth surface which does not require and preprocessing prior to rolling.
