Sintering Machine on Steel Mill

Sintering machine is a piece of equipment used in the process of sintering. Sintering is a heat treatment process that involves compacting and forming a solid mass of material using heat and pressure without melting it completely. The sintering machine is used to apply the necessary heat and pressure to the material to create a strong and durable final product. 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. Air is drawn down through the grate to produce downdraft combustion. As the bed moves forward, a very high heat (1,325°–1,500° C [2,400°–2,700° F]) is generated that converts the tiny particles into lumps about 2.5 cm (1 inch) in…
