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 steelsintering 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.
