Abstract

The invention relates to extruding methods combined with casting. The inventive method for extruding unlimited length products from a molten metal consists in pouring a molten metal into a container and in crystallising a billet, and uses a container (1) provided with a bush (2), wherein a matrix (3) is connected to one end face of the bush prior to casting and an extrusion stem, whose diameter is smaller than that of the container, is connected to the other end face thereof. The crystallised billet is pressed into a product (10) with the aid of the extrusion stem in such a way that a remainder of billet is preserved and a gap in the form of a residual shell is produced between the extrusion stem and the container. All surface defects of the billet are concentrated in said residual shell. Afterwards, the inventive method consists in returning once again the extrusion stem back to the barrel end face, in pouring a melt metal portion, in melting the residual shell by said metal, in crystallising and welding said melt metal portion together with the remainder of billet into a single billet and in carrying out a subsequent extrusion. The operations are repeated for required number of times. The aim of the invention is to obtain the products having a desired length, to reduces the metal utilisable wastes, and to improve the product quality by removing surface defects.
