The invention relates to a method and apparatus for obtaining an ingot wherein elastic oscillations are directed on metal being crystallized over a broad frequency range and at high intensity in the form of powerful pulses generated by a high-voltage spark discharge in liquid. One form of the apparatus of the invention comprises a discharge chamber filled with liquid in contact with a mould or with melt. The discharge chamber is provided with a system of electrodes connected to a pulse current generator. Upon feeding high-voltage current pulses to the electrodes, high pressure, impulse flows, cavitation and surge waves are built-up in the liquid resulting in the appearance of elastic oscillations acting on the molten metal.

Method and apparatus for obtaining an ingot

A continuous casting apparatus of a horizontal type is designed for simultaneous casting of a plurality of parallel strands from molten metal discharged from a common tundish. Each strand unit comprises a mold and a refractory conduit which are in contact with each other and in direct association with a clamping mechanism provided with means for adjusting the clamping pressure applied to said mold and conduit to enable closeness of contact therebetween. In combination with a cylinder mechanism intended for clamping conduits to a tundish, said clamping mechanisms provide for a fluid tight connection therebetween at the place of junction thereof.

Horizontal continuous casting apparatus

The process includes the delivery of molten metal for solidification in stepped flow and the blowing of a gas through the flow at a step located at the level of the surface of that portion of the flow which is directly fed for solidification, or at a level exceeding said level by as much as 300 mm. The apparatus for realizing said process comprises a tundish with a stepped bottom. A means for blowing the gas through the flow of metal is provided within that portion of the tundish which is located level with the upper generatrix of the outlet from the tundish or preferably, at a level about 300 mm above said generatrix.

Process and apparatus for horizontal continuous casting of metal

A continuous casting apparatus comprises a mold and a tundish connected to each other by means of a refractory conduit capable of withstanding several cycles of casting operations. Used on the continuous-casting apparatus is a dummy bar assembly whose head is bevelled on both sides thereof adjoining the mold wall. The bevelled portions of the dummy-bar head and the mold wall define a gap expanding in the direction of the withdrawal of the ingot. A sealing material, such as asbestos string, is placed in the gap and tamped therein by a special means.

Continuous casting apparatus

The withdrawal apparatus comprises a housing through which a cast ingot passes, said housing being mounted for reciprocating movement and for travelling in the direction along which the cast ingot is withdrawn and then back to its initial position. Mounted in the housing are shoes and wedge blocks with rollers arranged therebetween, said rollers being locked into position between the shoes and wedge as the housing travels in the direction of withdrawal of said cast section. The shoes are associated with a rod fitted with a compression spring bearing up against the housing and producing a force acting in the direction opposite to the movement of the housing during the withdrawal operation. When the withdrawal cycle is over, the shoes being spring-biased, release or unlock the rollers.
