The method consists in that a flat work in an initial position is oriented horizontally between cooled mold beams. Plasma torches are arranged in line across the parallel side edges so that the anode spots of the extreme torches are confined by said edges of the work. By supplying a plasma forming gas and electric current to the plasma torches the work is heated with the formation of a metal pool which extends across the work from edge to edge. By relatively moving the work and the plasma torches in a horizontal plane and along the edges of the work movement of the metal pool over the surface thereof is effected and thereby a remelted layer as thick as the pool is deep, is obtained. The apparatus for carrying out the method comprises a sealed chamber containing a mold having two beams arranged in a horizontal plane and being parallel to one another. Installed in the chamber are plasma torches mounted on shafts and connected through supply lines with the sources of plasma forming gas, electric current and cooling water. Each of the shafts is journalled in a sealing bush installed in the wall of the sealed chamber so that the axis of the shaft is parallel to the beams. Each shaft is rotatively driven by a drive. The apparatus further comprises a drive for relatively moving the work and the shafts in the plane parallel to the beams, connected with at least one of the elements taking part in such movement. The practice of the method with the help of the apparatus of the invention permits a high-quality work of a predetermined macrostructure of a surface layer, to be produced at a higher rate of treatment.

An apparatus for abrasive machining of workpieces comprises a base in the form of a carriage, a tool head having a spindle with an abrasive tool fastened thereto, an articulated four-bar linkage, a drive for rotating the abrasive tool and an actuating cylinder for urging the abrasive tool to a workpiece, the actuating cylinder being pivotally mounted on the base and a movable link thereof being pivotally connected to one link of the articulated four-bar linkage. The spindle of the tool head is arranged in a plane of the articulated four-bar linkage and connected to the drive for rotating the abrasive tool through a telescoping cardan shaft to thereby considerably reduce the bulk of the tool head movable parts and improve the tracing of the tool over the surface of the workpiece being machined.

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.
