Title: Process for producing a semi-finished powder metallurgy product
IPC: B22F3/11
Filed: 1998-01-16
Granted: 1999-12-27
Abstract: The invention relates to a process for producing a semi- finished powder metallurgy product for the production of metal foam, according to which process a powder of the matrix metal, e.g. aluminium, is mixed with a metallic foaming agent powder, e.g. titanium hydride, and is then compacted, for example by cold isostatic pressing (CIP) and is further compacted by extrusion, rolling or the like and is shaped into a semi-finished product, which semi-finished product can ultimately be foamed, in particular in a mould, by being heated to the melting point of the matrix metal resulting in dissociation of the foaming agent; scrap and waste material from the compacted powder mixtures and semi-finished product which has not been foamed are comminuted by shredders or granulation, cleaned if appropriate, mixed with mixtures of matrix metal powders and foaming agent, compacted and processed once again into a semi-finished product. <IMAGE>

Title: Process and apparatus for producing sponge iron particles and molten pig iron
Inventor: VULETIC BOGDAN
IPC: C21B11/02
Filed: 1986-01-22
Abstract: In this process for the direct production of sponge iron particles and molten pig iron from lump iron ore, which is reduced in a direct reduction unit (2) and supplied in the hot state to a melt-down gasifier (1), the sponge iron particles discharged from the direct reduction unit are separated into a fine particle fraction and a coarse particle fraction and only the former is supplied to the melt-down gasifier. Separation takes place in an air classifier (7) connected to the discharge means of the direct reduction unit and through said classifier flows cooling gas at a predetermined velocity in countercurrent to the sponge iron particles. This cooling gas is admixed with the reducing gas produced in the melt-down gasifier for the direct reduction unit and said gas mixture, as well as the fine particle fraction of the sponge iron entrained therewith are supplied to cyclones (5 and 6). The solid separated therein, e.i., the fine particle fraction and the coke particles, are introduced into the melt-down gasifier level with the coal fluidized bed. The gas mixture freed from the solids is used as a reducing gas in the direct reduction unit. Part is branched therefrom beforehand, washed and compressed and used as a cooling gas. The coarse particle fraction passes out of the air classifier into a cooling or buffer unit (4) and is then discharged therefrom.
