FIELD: production of articles by extrusion in combination with casting.
SUBSTANCE: method comprises steps of using extrusion container in one end of which die is mounted and in other end extruding ram with diameter less than that of container is mounted; casting metal into container; extruding ingot after its crystallization by means of ram at removing remainder of blank and forming gap between ram and container of press-jacket. In said jacket all surface flaws of ingot are concentrated. Then new doze of metal is cast into container and the last is welded with remainder of blank at crystallization. Press-jacket is melt by action of new doze of metal and ingot is extruded into the same product. Such operations are repeated depending upon desired length of product.
EFFECT: lowered quantity of circulating metal waste, improved quality of product.
