The Sintering Process in Powder Metallurgy |

Powder metallurgy processes use sintering to convert metal powders and other unique materials into end-use parts. Sintering typically takes place in a single, elongated furnace with different temperature zones. To facilitate the process, alloying elements or pressing lubricants may be added to the metal powder. In traditional solid state sintering, pressing lubricants are first eliminated via

PROCESS BRIEF - Ministry of Steel

Sintering process is developed mainly to utilize under size of lump ore called iron ore fines; which otherwise, could not be charged directly in blast furnace. In order to conserve these, otherwise waste material, they are compacted together and made into lumps by a process known as sintering.Sintering is defined as the agglomeration of the Iron ore fines (generally <8 mm) by incipient fusion

Sintering | metallurgy | Britannica

Sintering, the welding together of small particles of metal by applying heat below the melting point.The process may be used in steel manufacturing—to form complex shapes, to produce alloys, or to work in metals with very high melting points. In a steel-sintering plant a bed of powdered iron ore, mixed with coke or anthracite, is ignited by a gas burner and then moved along a traveling grate.

Sintering in the Powder Metallurgy Process

Transient liquid phase sintering. In a compact that contains only iron powder particles, the solid state sintering process would generate some shrinkage of the compact as the sintering necks grow. However, a common practice with ferrous PM materials is to make an addition of fine copper powder to create a transient liquid phase during sintering.

Mineralogy of Iron Ores of Different Alumina Levels from

In the sintering process, the iron ore corresponds to the mixture of hematite, goethite and other gangue mineral typologies. However the goethite and gangue contents are relatively lower than the hematite, but the goethite + gangue to hematite ratio influences the reactivity during sintering. The minerals association in iron ores and their chemistries affect the formation and composition of
