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.

Nitrogen Systems For Sintering Nitrogen Gas Generators

(Sintering is the process of melting and compressing metal into molds). Oxygen (which causes rust) is removed from the environment by introducing nitrogen into the process. Inerting with nitrogen gas and an onsite nitrogen generator during the sintering process eliminates the effects of oxidation, thereby improving quality while reducing cost.
