Abstract: The invention relates to compressing methods combined with casting and is used for producing products having a specified chemical content and length. The inventive method is the most close to an existing liquid metal forging (compressing) method consisting in pouring liquid metal in a metal reservoir (container), moving pasty metal from the metal reservoir to a die, crystallising metal, compressing a casting (ingot) and in extracting said casting from the die together with a extrusion discard. (See the patent RF N DEG 2033309, cl.B22D 18/02, published in 1995). The aim of said invention is to produce products having a required length and to reduce recirculating waste metal. The aim is achieved by the fact that for the inventive compressing method consisting in pouring liquid metal in a container and in crystallising said metal for producing an ingot, a container provided with a sleeve is used. Prior to casting, a die is arranged on one end of said sleeve, the other end being provided with a compression ram. When the ingot is produced, it is formed into a product with the aid of said compression ram. Afterwards, The compression ram is displaced to the sleeve end and filled with new portion of liquid metal. Said portion of liquid metal is crystallised and welded to the extrusion discard of the previous compressing in such a way that they are formed in one piece which is then formed into the same product. The longitudinal section of a device for carrying out said method is shown; on Fig. 2-view A on Fig. 1; on Fig. 3-view B on Fig. 1. The inventive device for carrying out said method comprises a container (1) provided with the sleeve (2), a die (3), a compression ram (4), a pressure plate (5) and a pouring channel (7). The extrusion discard, liquid metal and a final product are denoted on Fig 1 by positions 8, 9, and 10, respectively. The inventive method makes it possible to produce an article (tube, rod, wire, profile etc) having a required length up to several kilometres, reduce metal waste and decrease the energy consumption for metal-forming production process.

Abstract translation: 本发明涉及与铸造结合的压缩方法，并且用于生产具有特定化学成分和长度的产品。 本发明的方法最接近现有的液态金属锻造（压缩）方法，其包括将液态金属浇注到金属容器（容器）中，将膏状金属从金属容器移动到模具中，结晶金属，压缩铸件（铸锭） 并且在挤出废弃物的同时将所述铸件从模具中取出。 （见1995年出版的专利RF N°2033309，cl.B22D 18/02）。 所述发明的目的是生产具有所需长度的产品并减少再循环废金属。 这个目的是通过以下事实实现的：对于本发明的压缩方法，其包括将液态金属浇注到容器中并且使所述金属结晶以制造锭块，使用设置有套筒的容器。 在铸造之前，在所述套筒的一端设置模具，另一端设有压缩压头。 在制造锭时，借助于所述压缩冲头将其制成产品。 之后，压缩活塞移动到套筒端部并充满液态金属的新部分。 所述液态金属部分结晶并焊接到先前压缩的挤出废弃物上，使得它们形成为一体，然后形成相同的产品。 示出了用于执行所述方法的设备的纵向截面; 在图2中 - 图1中的视图A; 在图3中示出了图1的视图B.用于执行所述方法的本发明的装置包括设有套筒（2），模具（3），压缩压头（4），压力板 （5）和浇注通道（7）。 图1中的位置8,9和10分别表示挤出废料，液态金属和最终产品。 本发明的方法可以生产具有长达几公里的所需长度的制品（管，棒，线材，型材等），减少金属浪费并减少用于金属成形生产过程的能量消耗。
